Productivity, Nutrient Content and Uptake of Wheat (Triticum aestivum L.) as Influenced by Integration of Organic, Inorganic and Biofertilizers Nutrient Sources

Abstract

A field experiment was conducted during Rabi season of 2019-20 and 2020-21 at the Agricultural researchfarm of Rama University, Mandhana, Kanpur (U.P), to assess the response of integrated nutrient managementon yield and economics of wheat. The soil of the experimental field was sandy loam with pH 7.5, 0.41%organic carbon, 0.13 dSm-1 electrical conductivity, having available nitrogen 227.6 kg ha-1, availablephosphorous 13.9 kg ha-1 and available potassium 173.9 kg ha-1. The experiment comprised 11 treatments,viz., T1-Control, T2-100% NPK (120:60:40 kg ha-1), T3-100% NPK+ Zn (5 kg ha-1), T4-100% NPK + Zn + S (25kg ha-1), T5-100% NPK + Zn + S + Azotobactor + PSB, T6-100% NPK + Zn + S + Vermicompost (5.0 t ha-1), T7-100% NPK + Zn + S + FYM (5.0 t ha-1), T8-100% NPK + Zn + S + Vermicompost (5.0 t ha-1) + Azotobactor +PSB, T9-100% NPK + Zn + S + FYM (5.0 t ha-1) + Azotobactor + PSB, T10-75% NPK + Zn + S + Vermicompost(10.0 t ha-1) + Azotobactor + PSB, T11-75% NPK + Zn + S + FYM (10.0 t ha-1) + Azotobactor + PSB. The experimentwas laid out in randomized block design, replicated thrice. The maximum grain yield (4.84 t ha-1), proteincontent (%), nitrogen, phosphorous and potassium content and uptake were recorded in application of75% NPK + Zn + S + Vermicompost (10.0 t ha-1) + Azotobactor + PSB (T10) however organic carbon andavailable N, P2O5, K2O were found higher treatment T11 (75% NPK + Zn + S + FYM (10.0 t ha-1) + Azotobactor+ PSB) in during both the years.
