Plant Responses to Nutritional Stresses

Abstract

Early successes in breeding crop plants for increased yields resulted in selection for high nutrient requirements and high soil fertility. This often necessitated high inputs of fertilizers and soil ameliorants in order to achieve optimum yields and product quality. The costs involved and the environmental damage that often resulted from this approach has led to attempts to reduce mineral nutrient inputs and better fit crop plants to soils. This has been particularly important in agricultural production from infertile tropical and sub-tropical soils. The approach requires plant genotypes with high nutrient efficiency and tolerance to nutrient stresses. To help in production of such genotypes, the physiological responses of plants to nutrient stresses and the genetic controls involved in adaptation to those stresses need to be understood by those involved in plant improvement programs.
