| dc.description.abstract | Theinvestigation entitled “Effect of different levels of nitrogen and silica on yield and uptake of nutrients by rice in lateritic soils” was undertakenat Experimental Farm, Department of Soil Science and Agril. Chemistry, Dr.BalasahebSawant Konkan KrishiVidyapeeth, Dapoli, during kharifseason2017. The field experiment was laid out in Factorial Randomized Block Design with 4 levels of nitrogen and silica application viz. N0-0 per centRDN, N1-40 per cent RDN, N2-60 per cent RDN, N3-80 per cent RDN through KAB and Si0-0 kg Si ha-1, Si1-50 kg Si ha-1, Si2-75 kg Si ha-1 andSi3-100 kg Si ha-1through potassium silicate which were replicated three times and total sixteen treatment combinations were taken in the experiment. The initial experimental soil was well drained, sandy clay loam in texture, acidic in reaction with low electrical conductivity and very high organic carbon content. It was very high inavailable N and K2Oand low in available P2O5. The study indicated that, theapplication of 80per cent RDN through Konkan Annapurna Briquettes (KAB) in combination with silica @ 100 kg ha-1placedat7 to 10 cm depth @ one briquettes and one paper packet of potassium silicate for every four hills of rice was founduseful to increase the yield and yield attributing characteristics, grain and straw content of rice, total N, P, K and Si uptake and available N, P2O5, K2O, and Si status of soil. It is therefore concluded that, the placement of Konkan Annapurna Briquettes during kharif season in lateritic soils of Konkan region can reduce the recommended dose of fertilizer to the extent of 20 per centalong with 100 kg silica ha-1 to rice as a basal dose for increasing crop productivity as well as soil fertility. | en_US |
