Abstract

Effects of composted Cassava peels and Chromoleanaodorataon root-knot nematode disease and yield of soybean were studied in a 3 x 3 factorial experiment in randomized complete block design with 4 replications. These organic manures were applied to soybean varieties: TGX 1908-1; TGX1921-4F and TGX1485-1D in splits of 2 and 3kg per 1.2 x 1.5m seedbed. Results obtained 16 weeks after planting showed that the disease severity varied among soybean varieties and organic manures applied. Soybean susceptibility to the nematode was in the order: TGX 1921-4F >TGX 1908-1 >TGX 1485-1D. Significant (P=0.05) root-knot reductions however occurred on the soybean varieties on application of the organic soil amendments. This was more with composted cassava peels application but did not differ significantly from that of Chromoleanaodorata. Earliness to flowering and pod production correlated with root-knot reductions. The same was true for yields and amount of root nodules produced.

Keywords: Cassava peels, Chromoleanaodorata, nematode, root-knot, soybean, yield.
