Nutrient application reduces iron toxicity in lowland rice in West Africa

Abstract

Iron toxicity is a widespread nutrient disorder that affects rice growing in inland swamps and on irrigated lowland soils throughout the humid forest and savanna zones of West Africa. It has been reported to reduce lowland rice yields in West Africa by 12–100%, depending on the intensity of the toxicity and the tolerance of the rice cultivar (Sahrawat et al 1996)
