Combining organic and inorganic fertilizer has been proved to be an effective and sustainable soil management strategy for increased crop yield and safe environment. Field experiments were conducted in two locations in Nigeria namely Malete and Shao during 2018 and 2019 seasons. This was to find out the efficacy of organic and inorganic fertilizer (including prilled and granular urea) and their various combinations on grain yield and agronomic characteristics of maize. The use of full dose of P and K + 75% N through Granular Urea + 25 % N through farmyard manure improved most of the soil chemical properties with high economic returns. It was concluded from the experiment that a combination of organic and inorganic fertilizers is an environmentally friendly practice and could lead to high yields and improve farmers’ income and their livelihoods.
