EFFECT OF INTEGRATED NUTRIENT MANAGEMENT ON NITROGEN UPTAKE AND YIELD OF WHEAT CROP (TRITICUM AESTIVUM L.)

Abstract

A field experiment was conducted during the rabi season of 2013-14 and 2014-15 at Chandra Shekhar Azad University of Agriculture and Technology, Kanpur to evaluate the different levels of INM on nitrogen uptake and yield of wheat. The experiment was comprising sixteen treatments viz. T1-control, T2-100%RDF, T3-100%RDF+S, T4-100%RDF+S+Zn, T5-100% R.D.F.+S+Zn+bio-fertilizer (Azotobactor+P.S.B.), T6-100% R.D.F.+25% N through F.Y.M., T7-100% R.D.F.+25% N through F.Y.M.+S, T8-100% R.D.F.+25% N through F.Y.M.+S+Zn,T9-100%R.D.F.+25% N through F.Y.M.+S+Zn+bio-fertilizer (Azotobactor+P.S.B.), T10-100% R.D.F.+25% N through vermi compost, T11- 100% R.D.F.+25% N through vermi compost+S+Zn+bio-fertilizer (Azotobactor+P.S.B.), T12-75% R.D.F., T13-75% R.D.F.+25% N through F.Y.M., T14-75% R.D.F.+25% N throughvermi compost, T15-75% R.D.F.+25% N through F.Y.M.+S+Zn+bio-fertilizer (Azotobactor+P.S.B.) and T16-75% R.D.F.+25% N through vermi compost+ S+Zn+bio-fertilizer (Azotobactor+P.S.B.). Maximum accumulation of N at late tillering, milking and at harvest in grain and straw was recorded with T11 (100%R.D.F.+25%N through vermicompost+S+Zn+bio-fertilizers (Azotobactor+ P.S.B.) followed by T9 (100% R.D.F.+25% N through F.Y.M.+S+Z+bio-fertilizers (Azotobactor+P.S.B.) and minimum at control (T1) during both the years.

Highest grain yield was recorded in 46.50 and 44.70 q ha-1 with T11 (100% R.D.F.+25% N through vermin compost+S+Zn+bio-fertilizers (Azotobactor+P.S.B.) which was 104% and 108% higher to the lowest yield 22.80 and 21.50 q ha-1 at control T1 and 32% and 34.5% higher to 100% RDF treatment (T2 ). The maximum cost of cultivation Rs. 32270 and Rs. 35267, gross return Rs. 89032 and Rs. 90530 and net return Rs. 56762 and Rs. 55263 with the application of 100% R.D.F.+25% N through vermin compost+S+Zn+bio-fertilizers (Azotobactor+P.S.B.) T11 followed by T9 (100% R.D.F.+25%N through F.Y.M.+S+Zn+bio-fertilizers (Azotobactor+P.S.B.) and minimum was recorded with control (T1) during both year, respectively.
