Effect of Soil Conditioner (Biosil) and Recommended Dose of Fertilizer on Soil Properties, Growth and Yield of Wheat

摘要

A novel soil conditioner 'Biosil' has been developed from flyash through the process of magnetization. Field trials were carried out on wheat cultivar GW-273 using magnetized flyash 'Biosil' doses from 150 kg/ha to 900 kg/ha in combination with recommended dose of fertilizers (RDF), keeping control treatments of recommended dose of fertilizers and vermicompost (VC). These biosil doses were very low as compared to conventional doses (10% to 100%) given by other authors. It was observed that Biosil treatments improved the physico-chemical properties, of soil and wheat productivity with 750-900 kg/ha being optimum for most of parameters. Production of wheat grains in biosil treatment was 30% more than the recommended dose of fertilizers control. Maximum percentage increase under Biosil doses over recommended dose of fertilizers control in relation to plant population plant height, number of leaves/plant, number of effective tillers, length of earhead, number of grains/earhead, test weight and straw yield were 13.33%, 4.85%, 65%, 50.51%, 6.52%. 26%, 10.98% and 20.77%, respectively. Vermicompost control treatment was superior to recommended dose of fertilizers control treatment and over 150-450 kg/ha Biosil treatments in case of most of the parameters. However, long term field trials are required for recording maximum benefits of Biosil treatment at these low doses.
