Its major cash crops include&colon; groundnut, cotton, cowpea. The main agricultural products are corn, cassava, cowpea, peanut, and sweet potato. The legume pod borer, "Maruca vitrata," is the main preharvest pest of the cowpea. The bean beetle, "Callosobruchus maculatus", oviposit their eggs on the cowpea bean.
