Sulphur deficiencies have been reported from 72 countries in the world. Sulphur has a great role in N-fixation by influencing active nodulation in legume&despite the relatively low S requirement of rice, the productivity of these staple food grains may drastically be reduced by an inadequate supply of S. Sulphur has the ability to benefit more than one crop in sequence due to it s significant residual response. Application of higher dose of phosphorus (60 kg P205 /ha ) and increasing levels of sulphur up to 40 kg S/ha proved to be the best in improving the growth, yield attributing characters, grain yield of green gram. Varying levels of residual fertility and basal dose of nitrogen application significantly... ISBN:9783659125362 Издательство: "LAP Lambert Academic Publishing" (2014)
