different organic amendments on dry yield of corchorus. The treatments had a significant effect at (P< 0.05) on all the yield parameters collected. The treatment Velvet + IBBW1 gave the highest dried shoot weight (6.50 t/ha), Velvet fallow resulted into the highest total dry weight (7.22 t/ha), followed by IBBW2 treatment (7.16 t/ha). Comparative effect of Organic amendments on the soil properties Table 3 revealed that the treatment applied significantly affect the post fertility status of the soil. Treatment IBBW1 + Velvet (residual fertility) increased the soil organic carbon, nitrogen, available phosphorus, calcium and potassium when compared with the other treatments as well as the initial fertility status.

The least performance of the plants in the control was a reflection of soil nutrients deficit.
