Abstract

Thirty one soybean cultivars were evaluated for eight agronomic characters at two locations for 6 seasons in Coimbatore. The genotype mean square in the pooled analysis significantly exceeded the mean squares for interaction of genotype x location and genotype x season for all the traits. On black loam soil the seed yield. number of pods, seeds and nodes and height were greater than on red sandy loam soil. Sow- ing done in May has resulted in maximum production of nodes, pods, seeds and seed vield under red sandy loam soil and has produced maximum seed yield. besides taking maximum number of days to mature under block loam soil. All the varieties holding the top 10 ranks on overall mean seed yield basis were of tropical origin. EC 7034 produced the highest seed yield/plant. number or seeds and pods and had the maximum height at maturity.
