ABSTRACT
There is a need to grow cowpea and evaluate its yield. This will give adequate information on how well we are able to meet up with the demand for the crop. Identifying genotypes that can adapt to the Rainforest agro-ecological zone and also produce sufficient yields would help to boost the availability of cowpea grains for humans and animals in the zone and ensure food safety. The objective of this study was to evaluate yield and yield components of newly developed cowpea (Vigna unguiculata (L.) Walp.) genotypes in Benin City in a Rainforest agro-ecology of Nigeria. The experiment was conducted during the late growing season (September – December) of 2021 at the Teaching and Research Farm of the Faculty of Agriculture, University of Benin, Benin City(06°20°50N, 5°37'23''E;78 m asl), Nigeria. 30 genotypes of cowpea obtained from the Breeding Program of the Federal University of Agriculture, Makurdi, Nigeria were evaluated in the study. The experiment was laid out in a Randomized Complete Block Design (RCBD). Each treatment was replicated three times. Data were collected on the number of branches per plant, number of peduncles, seed yield and pod yield. No significant differences occurred among the genotypes for the parameters. This evaluation of the yield and yield components of the new genotypes were similar implying that the farmer would have to evaluate the implication of each option or management xi practices to make a decision that enables him choose which genotype to use in his farm.
