Abstract: The economic and financial viability analysis of a R$ 60,000.00 investment project was made for the production of biofortified Brazilian sweetpotatoes, in the rural community of ‘Panasco’, Nova Soure municipality in the northeast region of Bahia. The Minimum Attractiveness Rate varied in three scenarios: 10%, 11.50%, and 13.75%. The study used the Multi-Index Methodology to evaluate the return and risk attributes inherent to the investment project. After a detailed analysis of each attribute, investors accepted the TMA of 11.50%, and the indicators resulted in Present Value R$ 70,895.00, Net Present Value R$ 10,895.00, Annualized Net Present Value R$ 2.612,53, Cost Benefit Ratio R$ 1.18, Additional Return on Investment 2.82%, ROIA/TMA 24.52%, Internal Rate of Return 17.65%, Payback of 5 years, Payback/Horizon of 83.33% and TMA/IRR 65.16%. The Business Risk was evaluated with the cross-SWOT analysis. The Revenue Commitment Degree indicated that 68.72% of the revenue is committed to the full payment of the bills that make up the break-even point, with 31.27% of the revenue is taken as profit from the activity. Management Risk was accessed through a nine-point structured quiz so the investors pointed out that the Process and Social areas have greater control, but the Commercial and Administrative areas require greater attention in terms of business strategy. The project was approved, and the funding will be made for an agricultural work period of six years.

Abstract: Biosynthetic genes are responsible for antibiotic production by rhizobacterial antagonists. Detection of antibiotic biosynthetic genes of an antagonist is therefore important for the identification of genes and antibiotics responsible for disease suppression. The study was carried out to detect the antibiotic producing genes of eight rhizobacteria responsible for fungal disease suppression. Eight yam (Dioscorea sp.) rhizobacterial isolates which were found to possess antifungal properties against several plant pathogenic fungi and identified as Bacillus species were tested for the presence of genes for biosynthesis of antifungal lipopeptides; bacillomycin D, iturin A, surfactin, fengycin, and aminopolyols, zwettemycin A as possible antibiotic tools for biocontrol using specific primers. The detection of bacillomycin D gene by PCR amplification, gene sequencing, and BLAST analysis, was achieved through the use of the primer pair, BACC1-F/BACC1-R, capable of detecting 875-bp region, iturin A through the use of ITUD1-F/ITUD1-R primer pair, capable of detecting 647-bp region while primer pair SUR3-F/SUR3-R, capable of detecting 441-bp region was also used for the detection of surfactin. Three separate primer pairs were used for fengycin viz. FEND1-F/FEND1-R, FENA1-F/FENA1-R, and FENB2-F/FENB2-R, capable of detecting 964-bp region corresponding to fengycin D, fengycin A and fengycin B respectively. Zwettermycin A was detected through the use of ZWET-F2/ZWET-R1 primer pair, capable of detecting 1-kb region. The outcome of the study shows that all the eight rhizobacteria possessed biosynthetic genes for the production of bacillomycin D, iturin A, and surfactin, however, neither the three types of fengycin nor the zwettermycin A were detected. Sequenced data of these antibiotics have been deposited with GenBank and the following accession numbers assigned to bacillomycin D (MW263002-MW263009), iturin A (MW263010-MW263017), and surfactin (MW263018-MW263025). All the eight rhizobacteria tested were found to possess three out of the five biosynthetic genes namely bacillomycin D, iturin A and surfactin. The detection of these biosynthetic genes confirms and justify why these rhizobacteria are potential biocontrol agents of plant pathogens.

Abstract: Study of genetic variability is crucial in plant breeding to find traits of interest in genetic resources for any crop improvement. The present study was carried out using 36 genotypes including two checks to evaluate the mean performance of the genotypes, to examine the genetic variability, heritability, expected genetic advance and genetic advance as percent of mean. All the thirty six genotypes were tested using simple lattice design at Holeta Agricultural Research Center during 2018/2019. Observations were recorded on plot basis for days to flowering (days), days to maturity (days), yield per plot (g), yield per hectare(kg), oil yield (kg), oil content (%) and thousand seed weight (g) and on plot basis for plant height (cm). Analysis of variance revealed the significant differences among the tested genotypes for all traits considered. The phenotypic coefficient of variation observed in this study was higher than the genotypic coefficient of variation for all traits considered implying that high influence of environment on those traits. High phenotypic coefficient of variation was observed for all traits and moderate genotypic coefficients of variation recorded by seed yield per hectare, seed yield per plot and oil yield per plot. Low genotypic coefficient of variation was recorded by days to flowering, days to maturity, oil content, thousand seed weight and plant height. The study of genetic advance in this experiment showed high genetic advance for all traits except thousand seed weight which recorded low genetic advance.

Abstract: ENSET is a multipurpose crop in which every part is thoroughly utilized, not only for food but also for several cultural applications and livestock feed. It is primarily used as food, feed, medicinal, ornamental, and raw material for industries and construction materials. As a species, ENSET morphology is highly variable, although the extent of its variation remains unknown. The purpose of this study is therefore (i) to identify the existing ENSET diversity, (ii) to identify morphological trait variability among landraces of Enset, and (iii) to identify threats that affect ENSET diversity and to understand the associated indigenous knowledge in the study area with the ultimate goal of providing information that will help in constructing a scientific basis for the conservation and sustainable use of the plant. The study was carried out in ten purposively selected kebeles of three districts in the Gurage zone. A total of 100 (20 purposively selected key informants and 80 randomly selected general informants) were interviewed using semi-structured interviews; field observations and guided field walks were also used to collect ethnobotanical data. Morphological traits were measured according to Enset IBPGR (International Board for Plant Genetic Resources) descriptors. The data were analyzed by using computer software R v 3.2.2 and SPSS v 16.0 as well as an Excel 2010 spreadsheet. Direct matrix ranking and preference ranking were also used to analyze the ethnobotanical information. A total of 33 ENSET landraces were identified from the study area. Farmers give the name for their landraces based on morphological traits and sources of planting material. The identified landraces grouped into five clusters based on morphological trait variability. Mean plant height, pseudo stem height and cecum, leaf size and number were significantly different (p<0.05) among clusters. The most abundant landraces were Lemat Nechiwe Yeshirafire and Kanchiwe in Kabena District, whereas Agade and Yeshirakinke were the most abundant in Cheha. Yeshirakinke, Nechiwe, Agade and Kibinar were the most dominant landraces in the third study district. ENSET is an important food crop consumed in the form of bulla, Kocho and Amicho. In addition, ENSET is used as animal feed, as well as a source of medicine and fiber. This study confirms that the Gurage zone is rich in diversity of ENSET, but a reduction in production and loss of some landrace was observed because of different factors.

Abstract: Cotton growers from Northern Cameroon use chemical fertilizers to improve soil fertility. However, the use of chemical fertilizers exhibits an immediate solution to decline of soil fertility problem, but its exclusive use causes an increase of soil degradation. With the aim of sustainably increasing of cotton growth in Cameroon, study was conducted to evaluate effects of combinations of various strains of endogenous mycorrhizal fungi from Sudano-Sahelian savannahs of Cameroon on cotton productivity. Colonization rate, AMF diversity, cotton growth and yield were assessed according to suitable methods. Regarding the assessment of cotton productivy a 8×3×2 experimental design with 08 types of treatments, 03 experimental sites (Djalingo, Djabi and Djaba), and 02 cotton varieties (IRMA Q302 and IRMA L457) were used. Results shown that the colonization rate of cotton plant roots is higher in the Division of Mayo-Rey (93.33%). The cotton plants growth varies according to fertilizer and experimental area. There is no significant difference between cotton varieties relative to seeds yield and fibers yield. Endogenous mycorrhizal strains from Northern Cameroon better improve cotton productivity in our study areas than exogenous mycorrhizal strains in the range of 5 to 70%. Cotton fibers yield from Djaba site were 1.85 and 2.02 folds greater than that from Djalingo and Djabi respectively. Based on these results, the domestication and application of endogenous mycorrhizal fungi in North Cameroon for cotton growth is a contribution to increase cotton productivity and to limit the use of chemical inputs, as well as a guarantee of sustainable agriculture.
