Abstract: With “green-mindedness” increasing in popularity, the use of organic substrates has become more important in the retail Organic Agriculture. Yield of wheat is reduced due to limited water availability, poor soil fertility and low organic matter contents in the soil. This study comprised of field experiment on the use of organic amendments for growing wheat HD 3086 (Pusa Gautami) to find out their impact on crop growth, yield, and productivity. First experiment compared the efficiency of various organic manures applied solely and in different combination treatments of the chosen manures on loamy sand soil of the organic farm. The organic matters used in the experiment were: Azotobacter, Farm Yard Manure (FYM), Mustard Oil Seed Cake (MOC) and Neem Oil Seed Cake (NOC) @200g/acre, @ 26.67 t/ha, @2.40 t/ha and 1.71 t/ha Respectively. The data of the experimental year 2016–2017 on crop growth and yield attributes revealed that combination of Azotobacter +MOC gave the highest yield followed by NOC, and FYM+NOC. Combined application of MOC and other oil seed cake (OSC) showed significant increase in growth and yield of wheat, while integration of Azotobacter & MOC with other organic matter improved its effectiveness. Soil bulk density was affected significantly by the application of the treatments. Contrastingly, FYM and MOC alone or gave lower N contents in soil, as compared to the integration of the bio-fertilizer and the organic manures. The results revealed that highest N content in wheat grain and straw were found with Azotobacter and MOC and their integration with other organic amendments.
