Abstract
An experiment was conducted on S deficient soil during 2003–2006 on a farmer's field in the Jaipur district of Rajasthan, India, to study the direct effect of four levels of sulphur (0, 15, 30 and 45 kg S/ha) on pearl millet (Pennisetum glaucum) and their residual effect on Indian mustard (Brassica juncea). Results revealed that S fertilization up to 45 kg/ha significantly increased grain and stover yields and S uptake by pearl millet. Agronomic efficiency, physiological efficiency and value:cost ratio decreased up to 45 kg S/ha. S recovery was higher at 45 kg S/ha (21.4%). Residual effect of sulphur up to 45 kg/ha significantly improved the seed, stover and oil yields by 66.3, 49.4 and 95.9% of Indian mustard over control, respectively. Productivity, S uptake and apparent S recovery in the pearl millet-Indian mustard system increased with increasing level of sulphur up to 45 kg/ha while physiological efficiency was higher at 15 kg/ha (69.3 kg grain/kg of uptake). Agronomic efficiency and value:cost ratio increased with increasing S levels up to 30 kg/ha. Sulphur application improved the available sulphur status in the soil when applied at 30 and 45 kg/ha.
