Effect of integrated nutrient management on yield nutrient uptake and quality of wheat in central plain zone of Uttar Pradesh

Abstract

A field experiment was conducted during Rabi season 2013-14 and 2014-15 to study the Effect of integrated nutrient management on yield, nutrient uptake and quality of wheat in Central plain zone of Uttar Pradesh, India with sixteen treatments viz., T1-control, T2-(100 % R.D.F), T3-(100 % R.D.F. + S), T4-(100 % R.D.F. + S + Zn), T5-(100 % R.D.F. + S + Zn + bio-fertilizers (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-fertilizers (Azotobactor + P.S.B.), T10-(100 % R.D.F. + 25 % N through vermicompost), T11-(100 % R.D.F. + 25 % N through vermicompost + S + Zn + bio-fertilizers (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 through vermicompost, T15-(75 % R.D.F. + 25 % N through F.Y.M. + S + Zn + bio-fertilizers (Azotobactor + P.S.B.), T16-(75 % R.D.F. + 25 % N through vermicompost + S + Zn + bio-fertilizers (Azotobactor + P.S.B.) in randomized block design with three replications.Data revealed that integration of sulphur, zinc, bio-fertilizers and organic manures with 100 % RDF and 75 % RDF increased growth and yield attributing characters viz., plant population m-2 , plant height at 40, 80 DAS and at harvest stages of crop, dry weight of plant at 40, 80 DAS and at harvest stages of crop, number of effective tillers plant-1, ear length cm, number of spikelets ear-1 number of grains ear-1, grain weight ear-1, grain weight plant-1, test weight (1000-1 grain) than control. Highest increase in growth and yield attributing parameters newline
