Performance of Released Soybean Varieties at Jimma, South Western Ethiopia

Abstract

Soybean is becoming economical important oil crop in Ethiopia. The process of plant growth and development is important to the successful adaptation of a species to its geographic and climatic environment. Evaluating the adaptability of released soybean varieties in diverse agro ecology is important for efficient use of nationally released varieties in their area of adaptation and thereby increases production and productivity of soybean in the country. The trial was conducted with 19 released soybean varieties in the year 2015 and 2016 main cropping season at Jimma, South Western parts of Ethiopia. The experimental design used was RCBD with three replications. The parameters collected include; days to flowering, days to maturity ,number of pod per plant, number of  seed per plant ,hundred seed weight, rust ,common bacterial blight ,lodging score and grain yield. The statistical analysis showed significant difference at (P<0.05) among the varieties   for some parameters. The interactions of year by varieties showed significant differences for all of the traits except hundred seed weight. Mean grain yield ranged from 1.16 t/ha to 4.2 t/ha. The three high yielding varieties were Nyala (4.19 t / ha), Cocker-240 (3.9 t/ ha) and Williams (3.7 t/ ha). The above mentioned three varieties are recommended for south western Ethiopia.
