A field experiment was conducted during summer 2002 and 2003 at Bikaner to evaluate the effect of sulphur in improving iron nutrition for mungbean. The experiment comprised 32 treatment combinations of four sulphur and eight Fe levels. The results revealed that increasing levels of soil application of sulphur up to 40 kg/ha significantly increased active iron content of green leaves at 20 and 40 DAS, yield attributes, yield and N, P, K, S and Fe uptake in grains and straw, Application of 40 kg S/ha gave 65.9 and 29.5% higher grain and straw yields. Soil application of FeSO,@ 25 kg/ha increased the active iron content of green leaves markedly at 20 and 40 DAS over rest of the treatments. It also increased yield, yield attributes and N, P, K, S and Fe uptake in grains and straw significantly over rest of the treatments. Application of 25 kg FeSO, increased grain and straw yields by 66.6 and 34.3% over control. Foliar application of 0.5% FeSO+0.1% citric acid at branching and flowering stages remained at par with soil application of 25 kg FeSO, ha1 and produced 10.31 q/ha of grains.
