Breeding Crops for Tolerance to Acidic Soils in Ethiopia: A Review

Abstract

Soil acidity and associated low nutrient availability is one of the constraints to crop production on acid soils. In Ethiopia, soil acidity is a well-known problem limiting crop productivity. The management of acid soils should aim at improving the production potential by the addition of amendments to correct the acidity, manipulate the agricultural practices and using acid tolerant crops to obtain optimum crop yields. In this paper, we review some of the most recent applications of different breeding approaches for improving crop yield under acidic soils condition. In addition to this review paper aimed to put together recent achievements made through research on developing soil acid tolerant cereal and food legumes in Ethiopia. These newly released cereal and legume crops gave additional option for our farmers living in acid soil prone areas.
