| dc.description.abstract | A field experiment was conducted during rabi 2015-16 on gobhi sarson (Brassica napus L.) at the experimental farm of Department of Soil Science, College of Agriculture, CSK Himachal Pradesh Krishi Vishvavidyalaya, Palampur with nine treatments viz., control, 100% N through urea, 100% N through neem coated urea, 25% N through FYM + 75% N through urea, 50% N through FYM + 50% N through urea, 25% N through vermicompost + 75% N through neem coated urea, 50% N through vermicompost + 50% N through neem coated urea, 75% N through urea + lime and 75% N through neem coated urea + lime replicated thrice in a randomized block design. The soil of the experimental site was Typic Hapludalf, silty clay loam in texture, acidic in reaction, medium in organic carbon, low in available N, high in available P and medium in available K. Soil samples (0-0.15m) were taken at the harvest of gobhi sarson and were analyzed for bulk density, water holding capacity, pH, organic carbon, microbial biomass carbon and available N, P and K and micronutrient cations. The nitrogen use efficiency was calculated from crop productivity and total nitrogen uptake. The study revealed that 50% N through vermicompost + 50% N through neem coated urea resulted in highest gobhi sarson seed (22.1 q ha-1) and stover (50.5 q ha-1) yield. The productivity of crop recorded under 50% N through FYM + 50% N through urea was statistically at par with 50% N through vermicompost + 50% N through neem coated urea. The status of (N, P and K) nutrient, water holding capacity and microbial biomass carbon in soil improved in treatments where chemical fertilizers were applied in combination with organics and lime. The soil pH significantly enhanced in plots with lime application along with neem coated urea and urea. The DTPA-extractable micronutrient cations and organic carbon was also higher in treatments where chemical fertilizers were integrated with organics. Application of urea and neem coated urea in combination with organics and lime improved the nitrogen use efficiency. Highest nitrogen use efficiency was recorded in 50% N through vermicompost + 50% N through neem coated urea followed by 50% N through FYM + 50% N through urea. | en_US |
