ABSTRACT
An evaluation of four soybean varieties namely TGX 1440-IE, TGX 1485-1D, TGX 1805-17F and Samsoy I, intercropped with Okra NHAE 47-4 was conducted in the ultisol of Owerri south eastern, Nigeria in 2001 and 2002 cropping seasons. Samsoy I, was significantly different (p<0.05) in height, number of branches and economic yield from other soybean varieties studied. Again Samsoy I and TGX 1485-ID were significantly different (p<0.05) from TGX 1440-IE and TGX 1805-17F in terms of total dry matter yield (TDMY) nodule weight (mg/plant) and nodule number, indicating a high potential for N-fixation in the Owerri ultisol. Okra showed no significant effect as it performed uniformly both in height, branching habit and economic yield. The highest economic yield (1.2 t ha-1) and monetary value (N78,500.00 ha-1) was obtained by intercropping Samsoy I+okra. The crop combinations were not effective in suppressing weeds, therefore care has to be taken to keep all plots weed-free.
