Abstract
A field experiment was conducted at Awka, Anambra State, Nigeria to evaluate the growth and yield response of cucumber intercropped with different indigenous cowpea varieties. The experiment was laid out in Randomized Complete Block Design replicated three times. The treatments were three local varieties of cowpea (“Akidi Anaâ€, “Akidi Ocha†and “Akidi Ojiiâ€) which were sown sole, intercropped with cucumber include “Akidi Ana†+ cucumber, “Akidi Ocha†+ cucumber, “Akidi Ojii†+ cucumber, and sole cucumber. Results obtained from the study showed that the cowpea varieties intercropped with cucumber exhibited a significantly better growth and yield performance as compared to cowpea varieties sown as sole crop. “Akidi Ana†intercropped with cucumber recorded the highest yield advantage (22.8%) over the control followed by intercropped “Akidi Ojii†(22.4%). The result also showed that the intercropped cucumber had better yield compared with those sown sole. The intercrop between different cowpea varieties and cucumber was able to suppress weed emergence than the cowpea varieties and cucumber sown as sole crop.
