Abstract

Identification of cowpea varieties with superior grain yield and high soil fertility enhancing potential is crucial to increasing productivity of the crop among small-scale farmers in Omu-Aran, Kwara State. A field experiment was carried out during the 2014 growing season to evaluate two cowpea varieties for their grain yield and their effect on fertility status of Lateritic soils of Landmark University Teaching and Research Farm. The varieties evaluated were IAR 48 and IAR 2.5.6. Variety IAR 2.5.6 produced the highest grain yield compared to variety IAR 2.5.6. The study also revealed the potential of cowpea in improving the fertility status of Lateritic soils as there was significant difference observed in some of the chemical properties analyzed including available Phosphorus, Exchangeable Calcium, Magnesium, Potassium and Sodium.
