Effect of integrated nutrient management on yield and yield-attributing characters of wheat (Triticum aestivum)

A field experiment was conducted during the rainy (kharif) season of 2002 and 2003 to study the effect of different levels of organic manure (FYM) and inorganic fertilizers with different biofertilizer strains on wheat (Triticum aestivum L. emend. Fiori & Paol.). Application of 10 tonnes FYM + 120 kg N/ha significantly increased plant height, effective tillers/m row length, grains/spike, grain and straw yields over the control and 10 tonnes FYM + 100 kg N/ha during both the years. Both biofertilizers, i.e. Azospirillum and Azotobacter, significantly enhanced all the growth parameters and grain and straw yields over the control. Combined application of Azospirillum + Azotobacter showed significant improvement over their individual application.
