PROPER TIMING OF CHEMICAL WEED CONTROL AND FERTILIZER APPLICATION ENHANCES MAIZE GROWTH AND YIELD ACROSS NORTHERN GHANA: A REVIEW

Abstract

Maize is an important food crop in the world. Among the challenges affecting its production, weeds infestations and soil infertility play dominant roles across northern Ghana. Though several methods have been employed to manage these problems, the current average yield of 1.5 t/ha is far below the achievable yield of 5 t/ha. With the numerous work done on the incorporation of these management inputs in modern agriculture, this review identifies improper application of the inputs relative to the growth stages of the maize crop as an obstacle to attaining the desired yield. Much more marginal value in yield could be realized with the proper timing of the inputs in the maize production .
