Effect of iron and sulphur levels on yield, oil content and their uptake by Indian mustard (Brassica juncea)

Abstract

A field experiment was conducted during winter seasons (rabi) of 1999-2000 and 200041 to study the effect of graded levels of iron and sulphur on lndian mustard [Brassica juncea (L.) Czernj. & Cosson]. lndian mustard responded significantly to the application of Fe and S. The seed and stover yields increased linearly up to 20 kg Felha and 40 kg Slha. The seed yield (17.72 qlha) at 20 kg Felha was 12.4% higher than that obtained in the control. Similarly, application of 40 kg Slha gave the highest seed yield (18.37 glha), which was 28.1% more in comparison with that of the control. The uptake of Fe and S significantly increased up to 40 kg Slha and 40 kg Felha, and at 60 kg Slha and 20 kg Felha respectively. Oil content increased significantly with Fe and S addition. The added Fe and S were utilized maximum under application of the lowest levels of Fe and S.
