Acquisition of soil quality and crop productivity of aromatic rice under emerging production system

Abstract

An experiment entitled Effect of crop establishment methods and nutrient management on soil health and productivity of basmati rice (Oryza sativa L) was conducted at Crop research farm Nawabganj, College of Agriculture, Chandra Shekhar Azad University of Agriculture and Technology Kanpur (U.P.) in Kharifseason for two consecutive years (2015 and 2016) in irrigated condition. The soil of the experimental field was sandy loamy in texture.The physiochemical properties of soilviz.,pH(8.20 and 8.30) E.C.(0.22 and 0.21dSm-1),Organic corbon(0.48 and 0.38%), Available nitrogen (212 and 207 kg/ha), available P2O5(13.40 and 13.15kg/ha), available K2O (1380and 135kg/ha) and zinc (0.46 and 0.43mg/kg) respectively during 2015 and 2016.The experiment was conducted in Split Plot Design (SPD) with three replications and twelve treatments combination. The main plot was consisting of two establishment method (transplanting and aerobic rice) and sub plot consisting of six nutrient management treatments (control, 100 % RDF), 100 % RDF + Zn, 75 % RDF + 25 %N through organic manure, 50 %N RDF + 50 % through FYM and 100 % RDF through organic manure). Scented rice variety PusaBasmati-1509 was transplanted with the recommended agronomic practices.The maximum yield attributes viz. length of panicle, number of filled grains panicle-1, test weight and yield were recorded in transplanted rice as compared to aerobic rice under crop establishmentmethod. The maximum values of yield attributes viz. length of panicle, number of filled grains panicle-1, test weight and yield was observed with the application of 100% RDF +Zn (T3) which remained statistically at par with application of 75% RDF +25%N through organic manure (T4) during both the years. Among the different sources of manureFYM resulted in higher availability of nutrients because of its slow release after mineralization improving the soil environment. newline
