WATER USE EFFICIENCY OF MAIZE VARIETIES IN ACID SAND SOIL | Journal of Global Agriculture and Ecolo

Introduction: One of the primary constraints to rainfed crop productivity, especially on sandy soils, is water efficiency. Water usage efficiency (WUE) measurement is thus a good tool for comparing biomass output to grain yield. As a result, evapo-transpiration may be quantified in soil water balance studies in order to increase crop WUE. The goal of this study is to determine the amount of soil water utility by maize crop. Methods: Under rainfed conditions, two indigenous maize varieties (Mkprak and Uweb) and one enhanced variety (FARZ-7) were planted. The experiment was conducted in a randomised full block design with three replications. Each treatment had four micro-lysimeters inserted at random. The evapotranspiration at different stages of the crop was determined by weighing the micro-lysimeters two days after rainfall. Introduction: Water efficiency is one of the main restrictions to rainfed agricultural output, especially on sandy soils. The assessment of water consumption efficiency (WUE) is thus a useful technique for comparing biomass output to grain yield. As a consequence, evapo-transpiration might be measured in soil water balance studies to improve crop WUE. The purpose of this research is to figure out how much soil water a maize crop uses.

Two indigenous maize varieties (Mkprak and Uweb) and one improved variety (FARZ-7) were planted under rainfed circumstances. The experiment was carried out in a three-replication randomised complete block design. Four micro-lysimeters were randomly put into each treatment. Weighing the micro-lysimeters two days after harvest determined the evapotranspiration at various stages of the crop.
