Seasonal differences in iron toxicity tolerance of lowland rice cultivars

Iron toxicity is a major stress and yield-reducing factor in irrigated and rainfed lowlands in West Africa. Varietal tolerance is the most practical and cost-effective means of reducing iron toxicity in iron-toxic soils. We have been evaluating lowland rice cultivars for iron toxicity tolerance at Korhogo, Côte d'Ivoire, a site with a consistent and high iron toxicity pressure on plants. Because irrigation water is available, it was possible to evaluate germplasm in both the wet and dry seasons.
