| Legumes can play an important role in management of nitrogen (N) for vegetable production, especially in tropics where low native fertility is a major constraint to crop production. Thus, this report therefore presents evaluation of the influence of velvet bean-fallow (residual fertility) and compost on the yields of corchorus (Corchorus olitorus), as well as the post-harvest soil fertility quality. Corchorus was used as the test crop. Six treatments IBBW1 (Ibadan brewery waste based grade A), IBBW2 (Ibadan brewery waste based grade B), IBBW1 compost + Velvet residual fertility, IBBW2 compost + Velvet residual fertility, Velvet residual fertility (Sole) and no fertilizer treatment as a control were investigated. The compost was applied at 100 kgN/ha. The... |
