Agroclimatic Zonation for Wheat Production in the Savanna Region of Nigeria
Over the past few decades, demand for wheat in tropical and less developed countries has outweighed local production capacity. Increasing wheat production requires prior investigation of the crop’s requirements. In places with relatively low technology a naturally favourable environment is paramount for optimum production. In a tropical country such as Nigeria, climate appears to be the most critical factor for wheat growth. A new technique (or model) of delineating the savanna region of Nigeria based on its agroclimatic potential for wheat production is proposed in this study. Analytical techniques of multiple regression, hierarchical clustering and suitability rating were employed in determining the crop production potentials. Five suitability zones were identified. The study shows that the Jos Plateau and the adjacent high plains of Kaduna and Zaria have the best climate for wheat production in Nigeria. It also observes that the climatic potential for wheat production generally decreases equatorwards due to the consistently high temperatures and humidity.
