Summary in the original language of the document
Soybean (Glycine max (L.) Merrill) yield in tropical Africa remains below 1t/ha partly because most growers rarely use beneficial organic soil amendments on degraded tropical soils. Therefore, filed trials were conducted during the late cropping seasons (July – Nov.) of 2015 and 2016 on the organic research plots of the Institute of Food Security, Environmental Resources and Agricultural Research, Nigeria (7o 23´ N, 3o 39´ E, altitude 139 m above sea level) the trials evaluated the agronomic response of five recently released soybean varieties (TGx 1448-2E, TGx 1440-1E, TGx 1740-2F, TGx 1987-62F and TGx 1835-10E) to the application of three commercial organic fertilizers (Aleshinloye Grade B, Organo-Farm and Gateway) and a control. The trials were laid out in randomized complete block design (RCBD) in a 5 × 4 factorial arrangement and replicated three times. Data were collected on growth parameters, yield and yield attributes, and seed quality. Significant (P<0.05; F-Test) varietal difference was recorded for aboveground plant weight, grain filling period, height at physiological maturity, number and weight of pods per plant, number of branches and, seed yield and quality in both years. Application of organic fertilizers significantly (P<0.05; F-Test) increased aboveground plant weight, number of branches, pods, weight of seeds per plant, seed yield and quality in both years relative to the control treatment, except oil content and seed yield in 2016. The three organic fertilizers appear appropriate for soybean cultivation since soybeans grown on treated plots produced seed yield above 1/ton in both contrasting years of experimentation.
