Research Article of American Journal of Agricultural Research AGRO-MORPHOLOGICAL CHARACTERIZATION, CORRELATION AND PRINCIPAL COMPONENT ANALYSIS OF ELITE GROUNDNUT (Arachis hypogaea L.) VARIETIES IN UYO, SOUTHEASTERN NIGERIA Ofose, G. E., Bassey, E. E., and Udom, G. N. Department of Crop Science, Faculty of Agriculture, University of Uyo, Akwa Ibom State, Nigeria Field experiment was conducted at the University of Uyo Teaching and Research Farm, Uyo, Southeastern Nigeria during the 2021 cropping season to evaluate agro-morphological characters, and determine correlation coefficients and principal components in 10 groundnut varieties. The experiment which occupied a land area of 21.8m x 4.12m was laid out in a randomized complete block design in three replications. Characters studied were plant height (cm), number of leaves, leaf area (cm2), number of branches, length of petioles (cm), days to first flowering, number of pods per plant, number of seeds per plant, length of pods (cm), circumference of pods (cm), weight of pods per plant (g), harvest index (%), weight of 100 seeds (g), pod yield (tha-1) and seed yield (tha-1). Significant differences (p>0.05) were observed among the groundnut varieties for all the characters. The variety, RC-128B was superior over all other varieties in nine characters, namely number of leaves, leaf area (cm2), number of branches, number of pods per plant, number of seeds per plant, weight of 100 seeds (g), harvest index (%), pod yield (tha-1) and seed yield (tha-1), followed by RC-128S in seven, namely number of leaves, number of branches, number of pods per plant, number of seeds per plant, harvest index (%), seed yield (tha-1) and pod yield (tha-1), while RMP-24 was superior over the rest in six characters, namely plant height (cm) length of petioles (cm), plant biomass (g), weight of haulm (g), fresh weight of pods (g) and number of pods per plant.

Comparative effectiveness of turmeric (Curcuma longa), garlic (Allium sativum) and curry leaves (Ocimum africanum) against stored insect pest of Maize, (Sitophilus zeamais Motsch)

Research Article of American Journal of Agricultural Research Comparative effectiveness of turmeric (Curcuma longa), garlic (Allium sativum) and curry leaves (Ocimum africanum) against stored insect pest of Maize, (Sitophilus zeamais Motsch) AZEEZ, O.M. AND OKE, E. Department of Crop and Soil Science, Faculty of Agriculture, University of Port Harcourt, Choba, Port Harcourt, River State The bioactivity of turmeric, garlic and curry oil and powder were evaluated and compared against maize storage pest, Sitophilus zeamais (Motsch.) at 28+20C and relative humidity (r.h.) 65+5% in the laboratory. Ten pairs of newly emerged weevils were introduced separately into each of the plastics containing 20 g maize seed treated with plant oil at different concentrations, 0.25%, 0.50% and 1.00% v/v and similarly plant powder at dosage levels of 0.25 g, 0.50 g and 1.00 g of the tested plant parts. Each treatment, including the control comprised four replicates which were laid out 3x3 factorial arrangements in a completely randomized design. Results indicated that oil and powder of curry, and turmeric evoked significant mortality (82.50%) and (81.00%), while garlic powder is equally effective (72.00%) in achieving mortality of the weevil. There was an appreciable reduction in means of exit hole and percent seed damage in treated maize seeds at 0.50% and 1.00% concentrations. Curry had exit hole (12.25 &11.00), turmeric had (12.75&11.75); also lower seed damage was recorded in curry (11.00% & 21.75%), while turmeric had (20.75% &31.00%). There was however corresponding high percent undamaged seed recorded in curry (89.00% & 78.25%) and turmeric (79.25% & 73.25%). All the plant parts tested reduced weight loss in the stored maize seeds when compared with the control. Adult mortality significantly correlated with exit hole (r = 0.381), seed damage (r = 0.0509) and undamaged seed (r = -0.0643). Therefore, 0.50% was lowest concentration at which control was ...

Value Chain Analysis of Enset (Ensete ventricosum)

Research Article of American Journal of Agricultural Research Value Chain Analysis of Enset (Ensete ventricosum) in Dawuro Zone, Southern Ethiopia Berhanu Megerssa1, Ashenafi Haile2, Rijalu Negash1 1.Jimma University College of Agriculture and Veterinary Medicine; 2.Dawuro Zone Agricultural Office Introduction: Enset is a native food security crop in Ethiopia; and it has been served as emergency food crop in Vietnam during second world war. The crop is commonly used as staple food, and raw material for domestic and high-tech industries. Despite such opportunities, its production is declining due to introduction of new cereals, recurrent droughts and pests. There is also limited research conducted to address challenges. Methodology: Purposive sampling was used to select samples and three separate semi-structured interview schedules were used to collect data from producers, traders and consumers, accordingly. Tobit regression model was run to analyze market supply and intensity of market participation. Porter’s Value Chain Analysis tool was used to map the value chain. Result: Minimum and maximum number of enset trees harvested per year per household was 24 and 144, respectively; this was similar to National average. 34.75% of respondents consumed enset as alternative food due to skyrocketing prices of latter crops. Eight and seven marketing channels were observed in enset and bulla market, respectively. Recommendation: to ameliorate decreasing production and to increase farmers’ market participation, training should be given on enset value chain; intention should be done on integrated disease and pest management. Keywords: actors, Dawuro, enset, value chain, tobit ...

The main aim of this study is to identify the community development needs and potentials by assessing the challenges and prospects of the community under Chira watershed. Cross-sectional research design was employed. The data were analyzed by using frequency, percentage, mean, standard deviation, cross-tabulation along with inferential statistics like t-test; Chi-square test. The survey result indicated that only 17.5% of this land is conserved and covered by improved soil and water conservation measures. Only 17% of the respondents have used irrigation for crop production purpose and all of them were used traditional irrigation activities. Regardless of production increase, high price of fertilizer (50%), land shortage (25%), soil degradation (16.7%), lack of money (3.3%), lack of oxen (3.3%) and natural disaster (1.7 %) were mentioned as the current problems regarding crop production activities. Generally, infrastructure development in the area is weak and, therefore, much improvement is in need like developing roads, well developed farmer training center and demonstration sites, saving and credit institutions, electricity and mobile networks. Keywords: Assessment, Livelihood, Chira watershed, Ethiopia ...
