Effect of Integrated use of Organic, Inorganic and Bio-Fertilizers on Soil Fertility and Productivity of Wheat (Triticum aestivum L.) in Alluvial Soil

Abstract

The present experiment was conducted during rabi season of year 2020-21 at the Research Farm of Kulbhaskar Ashram Post graduate College, Prayagraj to study the Effect of Integrated use of Organic, Inorganic and Bio-Fertilizers on Soil Fertility and Productivity of Wheat (Triticum aestivum L.) in Alluvial Soil. The experiment was laid out in Randomized Block Design (RBD) with three replications and eleven treatments viz. T1-100% RDF (120:60:40 NPK), T2-75% RDF + 3 t/ha FYM + Azospirillum, T3-50% RDF + 6 t/ha FYM + Azospirillum, T4-25% RDF + 9 t/ha FYM + Azospirillum, T5-75% RDF + 2.5 t/ha WH + Azospirillum, T6-50% RDF + 5 t/ha WH + Azospirillum, T7-25% RDF + 7.5 t/ha WH + Azospirillum, T8-75% RDF + 1 t/ha VC + Azospirillum, T9-50% RDF + 2 t/ha VC + Azospirillum, T10-25%RDF + 3 t/ha VC + Azospirillum and T11-control. The results revealed that application of balanced fertilizers in wheat crop increased the growth, yield, yield attributing characters and protein content in grain. Integrated use of organic manure with chemical fertilizers and bio-fertilizers improved the soil properties in respect of pH, ECe, organic carbon, available N, P and K. The maximum reduction in pH and ECe was recorded with the treatment T10-25% RDF + 3 t/ha VC + Azospirillum and T3-50% RDF + 6 t/ha FYM + Azospirillum respectively. The organic carbon, available N, P and K were found maximum in treatment T8-75% RDF + 1 t/ha VC + Azospirillum.
