Abstract
The study on the evaluation of cowpea varieties for intercropping with okra was conducted during the late cropping seasons of 2008 and 2009 at the experimental farm of the Federal University of Agriculture, Abeokuta, Nigeria. The experiment was laid out in Randomised Complete Block Design replicated three times. Four cowpea varieties (oloyin, sokoto, IT84S 2246-6 and IT90K 2772-2) with determinate and indeterminate growth habits were planted as sole crop or intercropped with NHAe-47-4 variety of okra. Land equivalent ratio (LER) used to assess the productivity of the mixtures was consistently greater than unity in all treatments. Okra yield was not significantly reduced by intercropping in both years except in okra + IT84S 22466. Leaf area, LAI, number of flowers/plant and number of pods/plant were not significantly different (P=0.05) except in okra + IT84S 2246-6 in sole and intercrop mixtures. Intercropping enhanced the growth and yield of cowpea varieties compared to sole cropping. Oloyin, IT90K 2772-2 and Sokoto gave yield advantages of 147, 133 and 92% respectively.
