IMPACT OF DIFFERENTIAL SUBSTITUTION OF NUTRIENTS THROUGHORGANICS ON YIELD, NUTRIENT UPTAKE AND ECONOMICS OFBASMATI RICE IN IRRIGATED SHIVALIK FOOTHILLS OF J&K, INDIAMonika Banotra, B.C Sharma, Rakesh Kumar and Rohit SharmaAbstract A field experiment was conducted for two years at research farm of division of Agronomy at SKUASTJammuduring kharif 2015 and 2016 to assess the effect of differential substitution of nutrients throughorganics on yield, nutrient uptake and economics of basmati rice in irrigated Shivalik foothills of J&K. Thepooled data of two year study on basmati rice revealed that grain yield, straw yield and total nutrientuptake in basmati rice were significantly influenced by differential substitution of nutrients through organicsin irrigated Shiwalik foothills of J &K. Significantly higher pooled grain yield (30.38 q/ha) and straw yield(72.42 q/ha) of two year of basmati-370 were recorded with treatment 100% RDF which were foundstatistically at par with yields recorded with treatments T12, T16, T2 and T6 whereas significantly lowest grainand straw yield of basmati-370 were recorded with treatment 100 % NPK through FYM which was foundstatistically at par with treatment 100 % NPK through vermicompost and 100 % NPK through vermicompostand FYM (1:1) in grain and straw yield whereas significantly higher (75.37 kg/ha) total N uptake , total Puptake (13.13 kg/ha) and total K uptake (86.53 kg/ha) were recorded with treatment T11. Further, highestnet returns (Rs 66056/ha) and b:c ratio (3.18) in basmati-370 after two years were recorded with treatment100% NPK whereas lowest net returns (Rs 23213/ha) and b:c ratio (0.68) were recorded with treatment 100% NPK through Vermicompost in basmati rice. |
