Field experiments at three different locations on acidic soils of Bihar plateau were conducted in the late kharif season of 1997 to study the effect of graded levels of fertilizer sulphur @ 0, 15, 30, 45 and 60 kg ha−1 on yield, S-uptake and oil content in niger grown in Sdeficient upland soils. Grain yield, total S uptake, oil content and oil yield increased with successive S application up to 45 kg ha−1 in comparison to control. Mean increase of grain yield and oil content due to sulphur was 159 kg ha−1 and 3.7 per cent, respectively.
