Wilczeck] in arid western Rajasthan during summer season of 2004. The results showed that inorganic source of nutrients as NPK 100% of recommended dose and organic sources of nutrient like FYM 10 t/ha and vermicompost 5 t/ha significantly enhanced nitrogen, phosphorus and potassium content in seed and straw and total uptake of nitrogen, phosphorus and potassium of greengram and residual soil nitrogen and phosphorus after harvesting of greengram over control and lower levels of inorganic and organic sources of nutrient. Organic carbon of soil after harvest of the greengram significantly increased up to 125% NPK of recommended dose, FYM up to 20 t/ha and vermicompost up to 10 t/ha over control and their preceding levels. 收起
