Abstract
Multi-location field experiment was carried out at Sabon Layi and Yaulari, on effect of inter-row spacing on the performance of some selected varieties of soyabean (Glycine max (L)merr) experimental treatments consisted of three different inter row spacing of S1 (25cm 20cm) S2 (50cm) and S3 (90 20cm) allocated to the subplots respectively. Experiments were laid out in a split plot design replicated three times with total number of 27 plots. Parameters on count, plant heigh, number of branches, and number of pods, 100-seed weight and grain yield kg/plot were taken. Data were subjected to analysis of variance. Means were separated using Duncan Multiple Range Test (DMRT). Results showed among others, significant effects (P? 0.05) were recorded as count, plant heights at 6 (Weeks After Swaying) WAS and 9 WAS. The study recommends decrease in inter row spacing should be encourage in order to achieve high yield in the production of soyabean crop.
