The peanut is currently a common crop planted around the world. Nigeria is the largest groundnut producer in Africa accounting for 30% of the total Africa’s nut production and takes third place in the world peanut production (behind China and India). The nuts are mainly grown in the dry areas of Nigeria including Kano, Kwara, Sokoto, Zamfara, and Kaduna. Nuts are used in Nigeria to produce cooking oil and a source of protein for both human and animals. Groundnuts account for 70% of the total export earnings for the country.  Peanut is a crop demanding nitrogen in the soil that is why nitrogen fertilizers help to bring a higher yield.
