Suphur plays a vital role in the development of seed and improving oil quality. Groundnut is rich in oils and protein hence sulphur requirement for this crop is substantially high. Sulphur levels from 20 to 70 kg ha−1 were tried in groundnut among which higher level of sulphur @ 60 kg ha−1 has recorded taller plants, higher leaf area index, dry matter production pod number, pod yield and oil quality in groundnut. Gypsum application at 400 kg ha−1 (200 kg as basal and remaining 200 kg ha−1 during earthing up) has increased the pod yield, oil content and oil yield in groundnut.
