Pot and field trials were conducted to assess pod shattering in 15 varieties of soybean as affected by growth and yield attributes of the crop .Varieties used in this study included ; TGx1740-2F, TGx1871-12E, TGx1895-33F, TGx1019-2EB, TGx1485-1D, TGx1882-2F, TGx1880-3E, TGx1873-16E, TGx1842-1E, TGx1888-15F, TGx1866-7F, TGx1869-13E, TGx1848-10E, TGx1896-3F and TGx1448-2E At plant maturity, plant height and number of leaves, branches, nodes, pod, and shattered pod per plant, as well as pod length, pod diameter, pod weight and seed yield were assessed. Results indicated that variety TGx1888-15F had significantly the highest number of leaves while variety TGx1740 produced significantly the tallest plant. In field trial, there were no significant differences in the number of leaves per plant among varieties. Soybean varieties varied widely in their yield in both experiments. Variety TGx1448-2E produced the highest and significant seed yield while TGx1019-2EB had the lowest Pod shattering showed a significant negative correlation with pod diameter while plant height had negative but not significant effect on number of shattered pod per plant. The analysis also revealed that number of pod per plant, pod length, number of seed per plant, pod weight, seed weight and husk weight per plant had a direct but not significant effect on number of shattered pod per plant.
Key word: soybean, pod shattering, growth and yield attributes
