Abstract
Abstract A greenhouse study with rice Var. ‘Sena’ in two soils, black clay soil and saline sodic soil, indicated pronounced effect of Fe and Zn application on yield and concentration and uptake of these nutrients in plants at 30 and 60 days after transplanting and grain and straw at maturity. The yield and uptake of Fe and Zn increased considerably with the optimum supply of the respective nutrients in the soils. Mutual antagonism was observed between Fe and Zn mainly in respect to the concentration of these nutrients in plant, grain and straw and their availability in soil. Though the application of Fe and Zn to the soil decreased the concentration of each other in the plant by interfering in absorption and translocation of the other nutrient, still the uptake of these nutrients increased. Better yield and growth of rice with Fe and Zn fertilization is associated with higher uptake of nutrients. Uptake of Fe and Zn increased with the advancanent in growth. The yield and uptake of Fe and Zn without Fe and...
