Assessment of site specific nutrient management in hybrid maize (Kanchan)

Abstract

An experiment was conducted on farmer’s field in Amanari village of Sadar block: and Bend village of Katakamdag block under OFT for assessment of site specific nutrient management in hybrid maize (Kanchan) during kharif season of 2014 and 2015 in sandy loam soil of pH (5.88), low organic carbon, available nitrogen (166.25kg), available phosphorous (26.23kg/ha) and available potash (175.5kg/ha).There were three treatment including farmers practice (75kg Nitrogen, 43kg P2O5/ha.) as control, Recommended dose of fertilizers 80:60:40 (T2) and site specific nutrients management (Nutrients Expert dose 120:24:51) (T3). Among these treatments (T3) is found most suitable nutrient management technique for obtaining higher grain yield (43.60q/ha.), maximum net return (₹ 33891.0) and B:C ratio (2.49:1) in 2014. Similar result was also obtained in 2015 i.e., maximum grain yield (40.36q/ha.), higher Net Return (₹35399.0) and B:C ratio (2.68:1) in T3.
