ABSTRACT
The investigation entitled Effect of Organic Nutrient Sources on Soil Health and Productivity of Wheat under Rice-Wheat System was carried out at the Crop Research Centre of Sardar Vallabhbhai Patel University of Agriculture & Technology, Meerut, (U.P) during Rabi seasons of 2017-18. The experiment consisting seven treatments viz. T1- Control, T2- 10 t ha-1 FYM, T3-10 t ha-1 FYM +Cow urine + Azotobacter, T4- 10 t ha-1 Vermicompost, T5- 10 t ha-1 Vermicompost+ Cow urine + Azotobacter, T6- 7.5 t ha-1 FYM+ Cow urine + Azotobacter, T7- 80 % of RDF of nitrogen through vermicompost + 10 % through neem cake + Azotobacter was laid out in randomized block design with three replication. Result show that T7 (80 % of RDF of nitrogen through vermicompost + 10 % through neem cake + Azotobacter) significantly higher the growth and yield attributing character of wheat viz. plant height, dry matter accumulation, number of tillers m-1 row length, grains spike-1 and test weight over the control plot. it also recorded significantly higher spike length 67.69 % grain yield 70.16 %, test weight 52 % and harvest index 5% of wheat over control plot. The nitrogen, phosphorus and potassium content were higher in fertility levels of T7 and T5. However, lower bulk density and pH were recorded with T7 (80 % of RDF of nitrogen through vermicompost + 10 % through neem cake + Azotobacter) plot.
