While <em>Bryophyllum pinnatum</em> has been applied in the treatments of burns and scalds, boils, abscesses, gastric ulcers, wound, insect bites, lithiasis, edema of leg and other diseases, <em>Newbouldia laevis&nbsp; </em>has medicinal value ranging from anti-inflammatory, antioxidant, anti-microbial, anti-fungi, analgesic and wound healing properties.</p> <p><strong>Aim of the Study:</strong> To isolate bacterial organisms from wounds, and to comparatively screen the <em>in vitro</em> antibacterial activities of the extracts from the leaves of <em>Bryophyllum pinnatum</em> and <em>Newbouldia laevis </em>on the clinical isolates from wound infection.</p> <p><strong>Materials and Methods:</strong> Solvents used in leave extraction include ethanol, ethyl acetate and water. The extracts were tested against five organisms; <em>Staphylococcus aureus, Klebsiella species, Streptococcus pyogenes, Bacillus species, </em>and<em> Corynebacterium</em> <em>species </em>isolated from wounds<em>.</em> Phytochemical analyses of the plant extracts were also carried out using standard methods. Disc diffusion was used to determine the susceptibility of the organisms to the extracts while broth dilution methods were used to determine the Minimum Inhibitory Concentration (MIC) and Minimum Bactericidal Concentration (MBC).</p> <p><strong>Results:</strong> Results showed that the five test organisms had varied degree of susceptibility to the extracts. <em>Staphylococcus aureus</em> and <em>Klebsiella species</em> were the most susceptible to the extracts with zones of inhibition ranging between 6.0 to 10.0mm and 6.5 to 9.0mm respectively at concentration of 100mg/ml while <em>Bacillus species </em>was the least susceptible with inhibition zone diameter of 6.0 to 7.0mm at the same concentration. The Minimum Inhibitory Concentration ranged between 6.25 to 50mg/ml of the concentrations while the Minimum Bactericidal Concentration occurred at 50mg/ml for ethanol and ethyl acetate extracts of <em>Bryophyllum pinnatum </em>and ethanol extract of<em> Newbouldia laevis</em>. Phytochemical analysis revealed the presence of alkaloids, saponins, flavonoids, tannins, glycosides, and terpenoids. The extracts of <em>Bryophyllum pinnatum</em> had higher activity than extracts of <em>Newbouldia laevis</em> prepared in the same way.</p> <p><strong>Conclusions:</strong> The results suggest that extracts of both plants were broad spectrum in activity and has great potential in effective treatment of wound infections.</p> 2022-01-10T00:00:00+00:00 ##submission.copyrightStatement## INTERACTIVE IMPACT OF COMPOST AND BIOCHAR ON INDIGENOUS ARBUSCULAR MYCORRHIZAL FUNGI AND OKRA (Abelmoschus esculentum L.) PRODUCTION 2022-01-13T07:37:09+00:00 RANIA EL HILALI MARIYEM REHALI MOHAMED OU-ZINE SAID EL KINANY LAHCEN OUAHMANE RACHID BOUAMRI <p>Few studies have examined the impact of the effect of organic amendments on indigenous arbuscular mycorrhizal fungi (AMF) and okra growth. Our greenhouse experiment investigated the effect of compost or biochar amendments, and their combination, on AMF colonization of okra roots inoculated or not with indigenous AMF consortium inoculant using a completely randomized block design. The results showed that the inoculation of plant with indigenous AMF and the application of both compost and biochar significantly increased the colonization frequency and intensity up to 94% and 45.9%, respectively. The plant height and stem diameter were improved and reached 68.5 cm and 10.2 mm, respectively for treatment combining AMF inoculation, compost, and biochar application, against 21.5 cm and 3.5 mm, respectively for control. Fresh and dry weight of roots reached 38.7 and 28.03 g/plant, respectively for plants amended with biochar. Plants inoculated with AMF and amended with both compost and biochar showed fresh and dry weights of 30.5 and 23.3 g/plant. The highest okra yields were recorded with the treatment combining the AMF inoculation and compost application, followed by the treatment combining the AMF inoculation, compost, and biochar application. Therefore, these synergies between compost, biochar, and AMF may help farmers to increase the colonization of indigenous AMF strains in okra roots and consequently their abundance in the soil and to improve okra growth and yield.</p> 2022-01-12T00:00:00+00:00 ##submission.copyrightStatement## SOIL MICROBIAL COMMUNITIES AFFECT DEVELOPMENT OF Cedrus atlantica M. 2022-01-19T05:17:57+00:00 BELKACEM EL AMRANI MOHAMMED BENDRISS AMRAOUI <p>Soil microbial communities (SMC) play a key role in plant responses to environmental changes, particularly in cedar forest ecosystems, but the ecological and physiological effects of the microflora on <em>cedrus atlantica&nbsp;</em>are poorly understood. In this study, we investigated the dependence of cedar on natural soil microflora. The results showed that the Taz soil, compared to the other soils, stimulates the dry weight (DW) and decreases the root density of seedlings. In contrast to this, the dry weight responses to the enrichment are negative on Taz soil, but root density and tertiary root numbers are significantly increased. In native soil, Pearson test shows that the dry weight of cedar needles and stem are positively related to total microflora but that of the main root and secondary roots (R<sub>2</sub>) are negatively linked to fungi. On the other hand, yeast and actinomycetes are negatively correlated with R<sub>2</sub> abundance. The present study discusses for the first time the effect resulting from the interaction between native microflora of forest cedar soil on growth of <em>C. atlantica</em> seedlings.</p> 2022-01-18T00:00:00+00:00 ##submission.copyrightStatement## ANATOMICAL CHARACTERIZATION OF ROOTS OF SOME MEDICINAL PLANTS OF THE FAMILY EUPHORBIACEAE IN NIGERIA 2022-01-21T10:34:16+00:00 ONISODUMEYA E. JAMES BLESSING O. GREEN MERCY G. AJURU V. WILSON <p>This study has documented the root anatomical variability of some species of Euphorbiaceae in the Niger Delta region of Nigeria, as a means of providing information for quality assessment of herbal industry.&nbsp; Family Euphorbiaceae is also called spurge family consisting of about 322 genera and 7,700 species. Species are predominantly cosmopolitan with strongest representation in the humid tropical and subtropical regions of both hemispheres. Plants belonging to Euphorbiaceae family are widely used in Nigeria for various medicinal purposes. Based on this, seven species were selected for study from four genera which includes: genus Acalypha – <em>A. hispidia</em> and <em>A. wilkesiana</em>, genus Euphorbia – <em>E. heterophylla </em>and <em>E. hirta,</em> genus Jatropha – <em>J. curcas</em> and <em>J. gossipifolia</em> and the genus Manihot – <em>M. esculenta</em>. Transverse sections of the roots were obtained by free hand sectioning and submitted to double staining with methylene blue and safranin process for the anatomical study. Anatomical results of the roots revealed much variability among the species. Root characters such as the nature of the epiblema, cortex and vascular tissues are of high taxonomic significance. The secondary root has peridermis, parenchymatic cortex, collateral vascular system surrounded by sclerenchyma. The anatomical features are useful for dif­ferentiation among the species. This study will be helpful in correct identification and standardization of the plant material which is of medicinal importance.</p> 2022-01-21T00:00:00+00:00 ##submission.copyrightStatement## WATER BEHAVIOR FOR SOME WHEAT VARIETIES UNDER WATER DEFICIT CONDITIONS IN THE NORTH MIDDLE NILE DELTA REGION 2022-02-01T11:27:32+00:00 A.

A. GUJJA E. E. DISHAN Y. NASIRU <p>This research assessed nutrient status, in soil of date palm plantation of Modibbo Adama University, Yola Adamawa State. Parameters evaluated included; data on nutrient status of soils, based on growth performances of the date palm. The plantation was divided into three according to growth variabilities high, medium and low. Fifteen (15) auger points were taken, five (5) in each performance site based on the corresponding variability as observed. Soil samples were collected within same points for physicochemical analysis. One-way Analysis of Variance (ANOVA) was used to compare results of nutrient status of soils and to test for significant differences in nutrient concentration of the soils samples, mean separation was done using Least Significant Difference (LSD). &nbsp;The highest value for soil physical parameters in the growth sites were; sand 86.4%; silt 17.8%; clay 22.8%; BD 1.64g/cm<sup>3</sup>; PD 2.73g/cm<sup>3</sup> porosity 46% and WHC was 12.1%. Similarly, the highest value for soil chemical parameters in the growth sites were; pH 7.0, EC 0.60dS/m, OC 1.011%, OM 1.743%, TN 0.174%. AvP 12.637 ppm, Ca2+, Mg2+, Na+, K+, TEB TEA, ECEC and PBS highest values were; 5.212, 3.160, 0.957, 0.872, 9.186, 3.700,11.688 Cmol/Kg and 82.121% respectively. Analysis of variance for the soil parameters tested at (P ≤ 0.05) level of significance showed no significant differences in all the parameters of soil physical properties. However, Organic carbon, Organic matter and TN vary significantly after the Post-hoc tests across growth performance sites in chemical properties (p ≤ 0.05). The finding of this study revealed that there was no significant difference among the physical properties across the study site leading to the conclusion that soil physical properties may not have been responsible for the observed differences in the growth of the Date Palm in the plantation. A different pattern was however observed in the values of the chemical properties of the plantation where significant differences exist in Organic carbon, Organic matter and total Nitrogen across these sites which may perhaps be responsible for the observed differences in growth of the plants.</p> 2022-02-17T00:00:00+00:00 ##submission.copyrightStatement## EFFECT OF SODIUM HYPOCHLORITE ON SEED GERMINATION AND EARLY SEEDLING GROWTH OF SWEET ORANGE (Citrus sinensis (L).

They help in soil fertility, conservation, they hold the soil together, thereby preventing erosion. They also provide water, food, construction materials, windbreak, shade and aesthetic uses. An inventory of the plants in the University campus was undertaken to determine their family, genus and species compositions and thereby generate their checklist. Methods followed conventional practice as reported by previous authors of related studies. A total of three hundred and thirty-three (333) plants species belonging to two hundred and twenty- three (223) genera and eighty (80) families were identified and recorded. The most diverse families were the grasses, of the Poaceae family, consisting of 41 species and 26 genera, followed by the Asteraceae (29 species in 23 genera), Fabaceae (23 species in 16 genera), Cyperaceae (23 species in 7 genera), Euphorbiaceae (15 species in 8 genera), Lamiaceae (14 species in 9 genera), Amaranthaceae (11 species in 4 genera), Moraceae (10 species in 3 genera). Other families present had fewer species with fewer genera. Herbs (65.5%) were the dominant plant habit, followed by trees (17.7%), Shrubs (13.8%), Ferns (2.40%) and Liana (0.60%). The most dominant life form was the perennials (67.27%, followed by the annuals (29.73%) and annual/perennial (3.00) plants. This is the first comprehensive inventory/check list of plants present in the Rivers State University of Port Harcourt. With the continuous developmental activities, practical conservation approaches is ideal if the study area is to be saved from total loss of species.</p> 2022-03-05T00:00:00+00:00 ##submission.copyrightStatement## THE SPACING EFFECTS ON POTATO TUBER SEED YIELD IN FARTA DISTRICT, NORTHWESTERN ETHIOPIA 2022-03-17T13:29:41+00:00 BIRKIE TSEGA MEKONNEN ASRAT MELKAMU ALEMAYEHU <p>This experiment was conducted to determine the optimum row spacing of potato variety (CIP-393371.58) to seed tuber production in Farta District. Factorial combinations of three intra-row (25, 30 and 35cm) and four inter-row spacing (50, 60, 70 and 80 cm) treatments were laid out in RCBD with three replications. All phenological, growth and yield parameters were significantly affected by the main effects of intra and inter-row spacing while, fresh weight, average tuber weight, marketable tuber yield, unmarketable tuber yield, small size tuber weight and medium size tuber weight were highly significantly affected by their interaction effect. The optimum seed tuber, marketable tuber number per hill, total tuber number per hill, marketable tuber yield, total tuber yield and tuber yield and harvest index was obtained on 25cm intra-row spacing and 60 cm inter-row spacing planted potato. However, the economic analysis indicated that the highest marketable tuber yield (37.26 tha<sup>-1</sup>) was observed on25x60 cm intra-row and inter-row spacing crop. Whereas the lowest marketable and profitable yield was recorded at 25x50 and 35x70 cm intra-row and inter-row spacing, respectively. However, the highest net benefit was obtained from 25x60 cm spacing.&nbsp; Therefore, based on the finding of this study, it can be concluded that, high marketable, economically feasible and optimum Belete seed potato was obtained by planting potato at 25 cm intra-row and 60 cm inter-row spacing.</p> 2022-03-10T00:00:00+00:00 ##submission.copyrightStatement## GC-MS ANALYSIS AND NUTRACEUTICAL POTENTIALS OF THE BIOACTIVE COMPONENTS OF THREE EDIBLE COCOYAMS (XANTHOSOMA SAGITTIFOLIUM, XANTHOSOMA VIOLACEUM AND COLOCASIA ESCULENTA) 2022-03-23T12:53:54+00:00 SAMUEL C. ONUOHA REGINALD C. OHIRI ERESIYA A. DIRI <p>The productivity and growth of most developing economies of the tropics are severely threatened by malnutrition, due to their over dependency on carbohydrate-rich staples of high deficient micronutrients. Amongst the major roots and tubers, Cocoyams have better nutritional values because of their mineral compositions and protein digestibility. Mature tubers of three species of edible Cocoyams (Colocasia esculenta, Xanthosoma sagittifolium and Xanthosoma violaceum) harvested within the premises of&nbsp; University of Port Harcourt in Rivers State, Nigeria were peeled, washed, sliced, dried, ground and extracted using in dichloromethane. The pure and concentrated extracts were analyzed. GC-MS result of the bioactive components showed the methyl esters of Hexadecanoic acid and 9,12-Octadecadienoic acid as the highest components with percentage concentrations of 28.727 and 19.656, while Methyltetradecanoate and the (Z)-methyl ester of 9-Octadecanoic acid were the least components with values of 0.276 and 0.446. n- Hexadecanoic acid and 3-Hexadecyne were the highest components in X. sagittifolium with percentage concentrations of 34.783 and 33.504, while 1-Propanol, 2-methyl- and 1-Heptanol-6- methyl had the lowest percentage concentration with values of 1.219 and 1.187. The highest bioactive components observed in X. violaceum were n-Hexadecanoic acid and 1,3-Butadiene with percentage concentrations 37.613 and 16.510, while 1-Propanol-2-methyl and 1-Azabicyclo[2,2,2]octan-3- one had the least values with percentage concentrations 2.110 and 1.842. The diversity and variation in concentration of the bioactive components of these Cocoyams not only indicate varied specie-dependent potentials but also reveals the individual metabolic variations and nutraceutical potentials which can be of immersed importance to both pharmaceutical and food industries.</p> 2022-03-23T00:00:00+00:00 ##submission.copyrightStatement## ETHNOBOTANICAL STUDY ON MEDICINAL PLANTS USED BY LOCAL COMMUNITIES IN SHASHEMENE DISTRICT, WEST ARSI ZONE OF OROMIA REGION, ETHIOPIA 2022-03-24T11:42:24+00:00 TEGENU MEKURIA HIRPA ABDURO <p>Ethiopia is a country characterized by a wide range of climate and ecological conditions, possesses enormous diversity of fauna and flora. An ethnobothanical study was carried out to document information on the use of medicinal plants by local communities in Shashamane district, West Arsi Zone of Oromia Region, Ethiopia. The main method of study was semi-structured interview and discussion with informants from among Shashamane elders and healers. A total of 125 plants species belonging to 59 families were identified for their medicinal value, 45 species (36%) were Tree, 37 species (30%) were Herbs and 35 species (28%) were shrubs. Very few climbers 8 species; (6%) are used in the local traditional medical practices. The result shows plant species belonging to the families Fabaceae and Lamiaceae are most used. A total of 89 (71.2%) plant species are used for treatment of human ailments and 15 (12%) species are used for treatment of Livestock diseases and 21 (16.8%) species are used for treatment of both human and veterinary diseases. About 66 (52.8%) and 22 (17.6%) of the reported medicinal plants are taken orally and dermal respectively. Most of the plant species are wild, which is 79 plant species (63.2%) and 15 plant species (12%) are cultivated, and 21 species (16.8%) are both wild and cultivated which indicate that local people have little practice of bringing medicinal plants under cultivation. The prepared traditional drugs are administered through different routes of administration. The major routes of administration in the study area include; oral, dermal, nasal, Tooth and ocular. Oral administration is the dominant route (52.2%) followed by dermal route (27.6%). Some of the medicinal plant species were in the study area have multiple uses such as fuel wood, construction, overgrazing and charcoal production, and thus &nbsp;these plants are found under threats. The threats of medicinal plant species is main reason to the loss of the associated knowledge. It is therefore, recommended that interventions that promote traditional medicinal practices and those that help conservation of medicinal plants and local knowledge should be undertaken.&nbsp;</p> 2022-03-24T00:00:00+00:00 ##submission.copyrightStatement## AMELIORATIVE POTENTIALS OF DICHLOROMETHANE EXTRACT OF Musa acuminata LATUNDAN BRACT IN INDOMETHACIN ADMINISTERED WISTAR RATS 2022-03-29T11:34:23+00:00 B.

RAFEZ AHMED SUFIA AKTER MST ARJUARA SUMI MD. TOUHIDUJJAMAN MD. RAFI KHAN <p>The experiment was conducted in the Horticultural Farm of Sher-e-Bangla Agricultural University, Dhaka, Bangladesh. The experiment consisted of two factors. Factor A: Branch pruning and old leaf removal as P<sub>0</sub>= Control, P<sub>1</sub>= Old leaf removal, P<sub>2</sub>= Lateral branch pruning, P<sub>3</sub>= Old leaf removal and lateral branch pruning and Factor B: 3 varieties of brinjal as V<sub>1</sub>= BARI Begun-4, V<sub>2</sub>= BARI Begun-7, V<sub>3</sub>= BARI Begun-10. The experiment was laid out in a Randomized Complete Block Design with three replications. For pruning, the highest number of flower (38.87), the maximum number of fruit per plant (27.83) and the highest yield (49.73 t/ha) were recorded from P<sub>3 </sub>treatment, while the minimum were from P<sub>0</sub> treatment. In case of variety, the maximum number of flower (41.23), the highest number of fruit harvested per plant (29.23) and the highest yield (52.83 t/ha) were found from V<sub>1</sub> treatment, whereas the lowest from V<sub>2 </sub>treatment. Due to combined effect, the maximum number of flower (49.20), the maximum number of fruit harvested per plant (33.64), the highest yield (55.70 t/ha) were recorded from P<sub>3</sub>V<sub>1</sub>. So, it can be concluded that ‘BARI Begun-4’ with lateral branch pruning and old leaf removal gave the maximum yield. The highest gross return (1002600), highest net return (679649) and highest benefit cost ratio (3.1) were obtained from P<sub>3</sub>V<sub>1 </sub>(Old leaf removal and lateral branch pruning) treatment combination.

KHATAB <p>In Egypt, around 60% of cultivated lands of Northern Delta region are considered soil salinity areas. A two-year three field experiments were carried out to evaluate six Egyptian Barley genotypes under different soil salinity levels (4 , 8 and 12 dSm<sup>-1</sup>) during two consecutive seasons 2019/2020 and 2020/2021 using agro-morphological, &nbsp;germination percentage, seedling vigor, grain quality, stress indices, multivariable analysis and inter simple sequence repeats (ISSRs) marker. Increasing salinity level from (4 to 12 dSm<sup>-1</sup>) diminished the performance of all measured traits; however increasing protein content reached to 15.39% and heading data was quickens by 5.44% with strong and negative relationship with grain yield. Six salt stress indices were calculated based on grain yield; results showed that mean productivity (MP), harmonic Mean (HM) and stress tolerance index (STI) were more effective indices for detecting the high yielding genotypes. Ten ISSR primers were used to assess the genetic diversity among all genotypes; all primers showed high average percentage of polymorphic loci was 81.6%. The ISSR (UBC 835) primer generate the highest band number, polymorphism, polymorphism information content (PIC), effective multiplex ratio (EMR), diversity index (DI),), resolving power (RP), and marker index MI values were (8,100%, 0.50, 0.43, 5.80 3.20 and 0.88) respectively. Furthermore, ISSR (UBC 835) primer had amplified specific allele with molecular size 800 bp found in the tolerance cultivars (Line 4 and Giza 137) indicating that this primer is highly informative as a positive marker for salt tolerance. The heatmap cluster constructed using Euclidean distance and average linkage based on 12 phenotypic traits, seven salt tolerance indices and 10 ISSR primers showing that the six Barley genotypes were clustered into two main clusters, each cluster include the most closed genotypes together based on their response to salinity stress which could be used future in salinity breeding programs for high yield production under salinity soil areas in Egypt.</p> 2022-04-12T00:00:00+00:00 ##submission.copyrightStatement## WOODY SPECIES COMPOSITION AND COMMUNITY ANALYSIS OF EZANITULA FOREST IN CHENCHA WOREDA, SOUTHWESTERN ETHIOPIA 2022-04-13T11:07:47+00:00 TEGENU MEKURIA YORDANOS GERMAME <p>A study was conducted on Ezanitula (Nagasa Sacred) Natural Forest in Chencha Woreda, South west of Ethiopia, to conclude the Woody species composition and community type of the forest. A systematic sampling method was used to gather data from 36 quadrats (20m x 20m) established on four belt transects. All woody plants in the stands were counted and recorded as present. A total of forty- six plant specimens (31 trees, 11 shrubs, and 4 lianas) and each plant species belonging to 40 genera and 30 families were recognized. Asteraceae is the most dominant family followed by Euphorbiaceae and Rosaceae in terms of the number of species. Vernonia is the diverse genera followed by Scheflera and Maytnus. Four plant community types were identified. To detect similarities and dissimilarities among communities, Sorensen’s similarity coefficient was used and applied Shannon-Wiener diversity index to enumerate species diversity and richness. The woody species composition and community type status showed that irregular pattern which dictates need for serious conservation of the study area. Sacred forests are a hot spot of biodiversity conservation since it is a home of many rare, endangered, threatened, and endemic species of plants found in an area. This study revealed that numbers of valuable plant species are found in forest, and if conservation measures are not practiced in the near future there may be a great loss of plant genetic resources and other associated components of biodiversity.</p> 2022-04-13T00:00:00+00:00 ##submission.copyrightStatement## PHYSIOLOGICAL EVALUATION OF SOME WHEAT GENOTYPES UNDER WATER DEFICIT CONDITIONS 2022-04-15T12:09:27+00:00 OMNIA, S.

Important physiological traits of specific leaf area (SLA), crop growth rate (CGR), relative water content (RWC), stomatal resistance (SR), transpiration rate (TR), Photosynthetic pigments, Proline, total phenolic and glycine betaine, and lipid peroxidation (MDA) were studied. Results showed highly significant difference among wheat genotypes in all studied traits. The superior line1 indicated higher growth parameters, SLA, CGR, RWC, SR, Photosynthetic pigments, Proline, total phenolic and glycine betaine and showed decline in MDA and TR under1500m<sup>3</sup>/fad (Dry). These traits are recognized as beneficial drought tolerance indicators for selecting tolerant genotypes. Similarly, grain yield t/ha, straw yield t/ha, total soluble protein in grain, water productivity and harvest index of the same wheat genotype were also higher.

ESMAEIL <p>This work aims to study the effects of pre-sowing magnetic treatments of maize seeds (<em>Zea mays L.</em>) cultivar Triple hybrid 310 on its productivity and on some soil properties under different levels of mineral N-P-K fertilizers. A field experiment was conducted at a private farm at El-Menoufia Governorate, Egypt during two successive summer seasons (2020 and 2021) in a split plot design with three replicates. The main plots were the time of magnetic treatment of seeds (control, 5 min., 10 min. and 15 min.), while the sub-plots were the application rates of N-P-K fertilizers (50, 75 and 100% of recommended doses). The results showed that using magnetic treatments of seeds were better compared to the control treatments, it significantly increased the contents of N, P and K in plant and soil as well as total yield of maize, while reduced the soil pH and EC values. Also there were a relative increases by 3.98 , 15.89 and 23.37% for plant height (cm), 9.84 , 22.92 and 49.94% for weight of 100 grains, 16.51 , 36.79 and 50.94% for weight of ear yield (ton/fed), 20.14 , 40.96 and 54.26 % for straw yield (ton/fed) and 40.41 , 44.52 and 51.37% for grains yield (ton/fed), respectively for seeds treated with magnetic field for 5 min., 10 min. and 15 min., respectively, as compared to control. Also, there were significant differences in the values of yield parameters between the rates of fertilizers application (50 , 75 and 100% of recommended doses). Therefore, it can categorize the beneficial effects of the used magnetic field into different orders according the increases in maize yield parameters, as follows: 15 min. &gt;10 min. &gt; 5 min. &gt; control.</p> 2022-04-27T00:00:00+00:00 ##submission.copyrightStatement## BIOLOAD, ECOTOXICITY AND PHYSICOCHEMICAL EVALUATION OF PAINT INDUSTRIES’ EFFLUENT CONTAMINATED SITES IN ABA, ABIA STATE, NIGERIA 2022-04-28T12:41:31+00:00 UGOCHUKWU CHUKWUMA OKAFOR DAVID NWACHUKWU UMENEANYA FRANKLIN OBINNA UMEOZOR <p>The pollution index of paint industry effluent contaminated sites in Aba was evaluated.

The findings indicate that potato plants sprayed with potassium silicate had the best performance and yield quality compared to that treated with other K sources, while untreated plants recorded the lowest performance and yield quality. Potassium citrate came in the second order followed by potassium humate then potassium sulphate form. Regarding B foliar application, the performance and yield quality of potato plants increased as the rate of B increased. In other words, the best performance and yield quality for potato plants were recorded under combined treatment of potassium silicate and B at rate of 80.0 mgL<sup>-1</sup>. Generally, it can be concluded that potassium silicate form is the fastest and best form of potassium in potency and absorption inside the plant to stimulate and activate vital processes, increase the percentage of solids in tuber crops and sizing via spraying. As well as foliar application of B at rate of 80.0 mgL<sup>-1</sup> causes the transfer of most of the sugars and carbohydrates from the vegetative mass to the tubers.</p> 2022-05-09T00:00:00+00:00 ##submission.copyrightStatement## ANTIMICROBIAL SCREENING OF THE LEAF EXTRACTS OF Cissus aralioides (Welw. ex Baker) Planch.

Arg.) within the canopy of tapped trees of two <em>Hevea </em>genotypes, I.e. RRIC121 and RRISL 211. The leaf gas exchange parameters, I.e.Stomatal conductance (gs),Intercellular CO2 concentration (Ci), Leaf temperature (Tleaf),Transpiration rate ( E ),Water use efficiency (WUE) and Leaf-air vapour pressure deficit (lvpd) were measured under optimal environmental conditions. Study findings clearly revealed that the intercellular CO2 concentration (Ci) gradually decrease with increasing light intensity in both clones. The same trend was observed in the different canopy layers under both tapping treatments.Clone RRISL 211 showed a higher leaf temperature than RRIC 121 under tapping. The highest leaf-air vapour pressure deficit (lvpd) was shown in the leaves of the upper canopy and lowest in the bottom canopy layer. Furthermore, the water use efficiency (WUE) of clone RRISL 211 was higher than that of clone RRIC 121 under tapping. In the tapped treatment, because of tapping, the photosynthetic rate is stimulated relative to the transpiration rate. The positive latex yield response to WUE and lvpd of top leaves indicates that, in top leaves when lvpd increases transpiration also increases accordingly. Clone RRIC 121 showed a greater contribution from the middle layer to overall canopy photosynthesis while RRISL 211 showed a lower contribution. This could have been due to the more open canopy architecture in clone RRIC 121 or maintenance of a higher A in low light levels.</p> 2022-08-12T00:00:00+00:00 ##submission.copyrightStatement## PHYSIOLOGICAL, VEGETATIVE, AND PRODUCTION RESPONSE OF PEACH TO WATER RESTRICTION DURING SLOWDOWN PERIODS OF FRUIT GROWTH 2022-08-27T11:59:49+00:00 MERIAME LAITA ZERHOUNE MESSAOUDI RACHID BENKIRANE HOUSSAIN AITHADDOU <p>The low rainfall and poor rainfall in recent years in Morocco, have led to a situation of water deficit throughout the cropping cycle, including stone fruits.

The study was carried out (in two replications in 2017 and 2018) four water regimes during slowdown periods of fruit growth: T0 (equal to or greater than 100% of the crop's Evapotranspiration (ETc)), T1 (100% ETc), T2 (80% ETc) and T3 (60% ETc). The response of trees is presented for physiological indicators – vegetative development , production and quality parameters for the two years. The effect of RDI on peach trees showed that water restrictions varied according to the water regime. The decrease in irrigation rate negatively affected the main vegetative and production parameters. However, for the 20% decrease in irrigation rate, the effect on yield was not significant. Regarding vegetative growth, the T3 (60%ETc) water regime significantly affected the increase in length and diameter of the current year's shoots, while the T2 (80 % ETc) water regime did not affect leaf area. Trees from treatment T3 (60 % ETc) yielded fruits with the highest sugar content. This increase in sugar content was accompanied by a decrease in the total acidity of the fruit juice.</p> <p><strong>&nbsp;</strong></p> 2022-08-27T00:00:00+00:00 ##submission.copyrightStatement## IMPACT OF POLYURETHANE COATED FERTILIZERS ON SOME SOIL CHEMICAL PROPERTIES AND WHEAT PRODUCTIVITY IN SANDY SOIL 2022-08-31T09:44:55+00:00 M. A. ESMAEIL A. K. ABDEL FATTAH S. H. ABD ELGHANY A. A. ARAFAT <p>Two field experiments were carried out at Ismailia Agricultural Research Station, Ismailia Governorate, Egypt, during the two winter seasons 2020/2021 and 2021/2022 to estimate the impact of different doses of polyurethane coated fertilizers on some chemical properties of soil and wheat productivity in sandy soil. The experiment units were arranged in a complete randomized block design. Results elucidated that soil chemical properties were improved as a result of the studied treatments. Soil EC values were significantly decreased in the studied treatments than those of control. The best addition was 75% coated RD. The studied treatments caused significant increases in the values of organic matter content of soil. Values of pH were slightly decreased. There were significant increases in the values of soil available micronutrients (iron, manganese and zinc) and available macronutrients (nitrogen, phosphorous and potassium) after applying the studied treatments. The highest values of soil macro and micronutrients were recorded in 75% RD coated fertilizers, while the lowest values were found in 25% RD coated fertilizers. Concerning wheat yield parameters, there were significant differences in values of grains, straw yields and weight of 1000 seeds between the treatment (25% RD coated) and all of the other treatments. The highest yield values were found in the treatment (75% RD coated), while the lowest values were recorded in (25% RD coated). There was a slight difference between control and each of (50% RD coated) and (75% RD coated). The treatment (50% RD coated) gave yield values near to the control (100% mineral RD). This means that this treatment save about 50% of the used traditional N-P-K fertilizers.</p> 2022-08-31T00:00:00+00:00 ##submission.copyrightStatement## IRRIGATION WITH MAGNETICALLY TREATED WATER ON THE EFFICIENCY OF PHOSPHORUS FERTILIZERS AND IMPROVING THE PRODUCTIVITY OF WHEAT PLANTS GROWN ON DIFFERENT SOILS 2022-09-06T09:23:12+00:00 KHOLOUD A. EL-NAQMA M. M. A. SHABANA M. A. EL-SHERPINY <p>In most soils of Egypt, the activity of calcium is high and this negatively affects phosphorus availability, thus declining of efficiency of added phosphorus fertilizers, moreover, the country faces water deficit issues. So, a lysimeters trial was executed during two successive seasons to evaluate the performance and productivity of wheat plants grown on different soils <em>i.e.,</em> clayey, loamy, sandy and sandy loam as mainplots under two treatments of irrigation water <em>i.e.,</em> non-treated water <strong>(W<sub>1</sub>) </strong>and magnetically treated water<strong> (W<sub>2</sub>) </strong>as subplots (using well water having low quality) and calcium superphosphate additions as sub subplots <em>i.e.,</em> 100% of phosphorus recommended dose PRD in mineral form (<strong>P<sub>1</sub></strong>) , 75% of PRD in mineral form + phosphorein (<strong>P<sub>2</sub></strong>) , 75% of PRD in mineral form + compost (<strong>P<sub>3</sub></strong>) and , 75% of PRD in mineral form + phosphorein + compost (<strong>P<sub>4</sub></strong>), where calcium superphosphate represented the P mineral form. Also, the effect of studied treatments on some soil properties was assessed. The main results showed that wheat plants grown on clayey soil had the best performance <em>i.e., </em>chlorophyll content, N, P and K in leaves after 60 days from sowing as well as the best yield and its components compared tothat grown on other soil types, where the loamy soil came in the second-order and calcareous soil came in the third order, while the sandy soil came in the last order. Wheat plants under irrigation with magnetically treated water had performance and productivity better than wheat plants irrigated with non-treated water. Regarding combined additions of PRD and bio and organic fertilizers, the superior treatment was <strong>P<sub>4</sub></strong> followed by <strong>P<sub>3</sub></strong> then <strong>P<sub>2</sub></strong> and lately <strong>P<sub>1.</sub></strong> Differences resulting from interaction among studied treatments were significant, where the superior combined treatment was when wheat plants were grown on alluvial soil and simultaneously were irrigated with magnetically treated water and were treated with 75% of PRD in mineral form + phosphorein + compost.Magnetically treated water positively affected soil fertility expressed in soil content of available N, P and K. Generally, it can be concluded that irrigation with magnetically treated water under bio and organic fertilization may be an effective way for increasing the efficiency of phosphorus fertilizers and improving the productivity of wheat plants grown on different soils.</p> 2022-09-06T00:00:00+00:00 ##submission.copyrightStatement## INVESTIGATION OF SUITABLE PROTOCOL FOR IN-VITRO PROPAGATION OF Kendrickia walkeri 2022-09-27T10:58:13+00:00 M. A. T. NIROSHINI H. K. L. K. GUNASEKERA S. A. KRISHNARAJAH M. M. D. J. SENARATNA <p><em>Kendrickia walkeri</em>, is an epiphytic climbing shrub that belongs to the Melastomataceae family and it is vulnerable and included to the National Red List 2012 in Sri Lanka. Hence present study was aimed to find out suitable potting media for vegetative propagation and to develop suitable protocol for in<em>-vitro</em> propagation of <em>Kendrickia walkeri</em>. The pot experiment was laid out in a Completely Randomized Design (CRD) with three treatments randomized in seven replicates. Treatments were three different potting media i.e. coir dust only, coir dust: sand and coir dust: leaf mold: sand. Semi-wood stem cuttings were planted and each pot were kept in single propagators for twenty one days. After that, the data were obtained on stem height, number of new leaves, number of shoots and number of roots with two weeks intervals. Data were tabulated and analyzed using Analysis of Variance (ANOVA) procedure of Statistical Analyzing System (SAS). Duncan’s New Multiple Range Test (DNMRT) was performed to compare the differences among treatment means at p=0.05. Among different treatments the highest stem height, number of leaves/shoots as well as roots per plant was recorded in coir dust, leaf mold and sand medium. The laboratory experiments was laid out in a Completely Randomized Design (CRD) with six treatments randomized in four replicates. Treatments were different protocols i.e. 1% HgCl<sub>2</sub> (3 minutes), 1% HgCl<sub>2 </sub>(4 minutes), 2.5 % Clorox + 1% HgCl<sub>2</sub> (4 minutes), 5 % Clorox + 1% HgCl<sub>2</sub> (4 minutes), 7.5 % Clorox + 1% HgCl<sub>2</sub> (4 minutes) and 2.5 % Clorox + 1% HgCl<sub>2</sub> (5 minutes). Nodes were treated according to the protocols and inoculated in Murashige and Skoog (MS) medium supplemented with 1.5 mg/ L benzyl amino purine (BAP). The data of number of survived explants were taken with three days intervals. The highest number of survived explants were recorded under, 2.5 % Clorox + 1% HgCl<sub>2</sub> (5 minutes) protocol. Hence, coir dust, leaf mold and sand medium can be considered as a successful potting media for vegetative propagation of <em>K. walkeri</em> by nodal stem cuttings and <em>K. walkeri</em> exposed to 70 % ethanol for 15 seconds, 2.5% Clorox for 5 minutes and 1% HgCl<sub>2</sub> for 5 minutes duration, can be recommended for direct plantlet regeneration from nodal explant of <em>Kendrickia walkeri</em> and further studies for micro propagation technique.</p> <p><strong>&nbsp;</strong></p> 2022-09-27T00:00:00+00:00 ##submission.copyrightStatement## ANALYSIS OF PROFITABILITY AND THE LEVEL OF AGRONOMIC AND ECONOMIC EFFICIENCIES AMONG SMALL-SCALE PRODUCERS OF RICE IN RUZIZI PLAIN, EASTERN D.R. CONGO 2022-03-29T11:41:27+00:00 NAKISHUKA BITAISHA SHUKURU <p>Efforts have been made to promote local rice production to meet both local demand and improve the income level of small-scale producers involved in rice cultivation in D.R. Congo, especially in its east part. The work aims to understand the current dynamics of rice supply &amp; demand, and the level of agronomic &amp; economic efficiency of the factors of production. A quantitative study, using a well-structured questionnaire survey, was conducted to request information on the efficiencies and cost-effectiveness of the factors influencing the quantities produced and the demand available. The concept presented as area exploited, fertilizers, price explained the rice supply and demand. Total cost of fertilizers, coefficient of work efficiency, land productivity, productivity rate of capital, net income, value-to-cost ratio were used for rice profitability and efficiencies analysis. The level of agronomic efficiency of fertilizers is 59.73 and 88.09, respectively in BVB and LVA. Fertilization with NPK positively influences the yield of rice cultivation. The economic efficiency is expressed according to the value-cost ratio (VCR) and net income (NI) indicators. VCR is 39.3 and 40.3, respectively in LVA and BVB. The average NI values of 3152.4, 2595.6 and 892.1 were recorded respectively in LVA, BVB and LVC. The supply is provided by rice farmers, at a very affordable price of 0.57 US$ per kg. For 80% of small producers, the demand for rice products is available. Besides the productivity of the land is 4379.7 US$ per hectare, as well as the labor hired allows to produce more. The coefficient of labor efficiency being 5.07 (CWE &gt;1) and is all well paid. The financial and commercial profitability recorded by rice producers per hectare is 1.0217 and 0.495 respectively. There are several factors explaining household behavior towards rice demand and supply in the Ruzizi plain, including price, available demand, agronomic and economic efficiencies, and profitability.</p> 2022-03-29T00:00:00+00:00 ##submission.copyrightStatement## EXTENSION IN DISTRIBUTION RANGE OF RARE GENUS IPHIGENIA IN PEER PANJAL RANGE OF JAMMU & KASHMIR, HIMALAYA 2022-04-27T11:01:36+00:00 MUSHTAQ AHMED PREM SINGH CHAUHAN SAFEER AHMED MANJUL DHIMAN <p>In present study <em>Iphigenia indica </em>(L.)

REDAE K. HAILEGEBRIEL G. WELDEGERIMA G. TSEGAY T. YIRGALEM A. EYASU S. HUSSIEN <p>Rice is a very fascinating crop because of its higher yield real adoption by farmers and its adaptative to water logged soils. The use of chemical fertilizers is an essential component of modern agriculture but is being checked by sustainability issues. Global food systems are not only failing to keep us all fed, but they are also failing to keep us healthy too. Managing land to produce food, fiber or timber must have some environmental impact, the magnitude of which will depend on the cropping system and the intensity of management. Nitrogen (N) is central to living systems. Nitrogen is a major component of proteins, hormones, chlorophyll, vitamins, and enzymes essential for plant life. The addition of N to agricultural cropping systems is an essential facet of modern crop management and one of the major reasons that crop production has kept pace with human population growth. However, nitrogen fertilizer and its management have been the subject of considerable research and debate for several decades because the benefits of N added to cropping systems come at well-documented environmental costs due to lack of proper management. Excessive rates of N fertilizer can lead to losses of inorganic N from agricultural lands into surface water and groundwater, thereby threatening our environment. Rice production consumes about 20% of the total N fertilizer used for agriculture in the world. N fertilizer is often not effectively used by rice in general and irrigated rice in particular because of improper management. Inefficient N management practices have contributed to low (30–40%) NUE estimates for cereal crops. To achieve high yield and high partial factor productivity of N, a scientifically integrated nutrient management strategy based on a comprehensive understanding of the causes of the crop’s yield and knowledge on the nature of nitrogen fertilizers is mandatory.</p> 2022-01-04T00:00:00+00:00 ##submission.copyrightStatement## RESPONSE OF ROSE (Rosa hybrida L.)
