Effect of organic nutrient sources on plant nitrogen, phosphorus and potassium content at different stages of wheat crop

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 plant Nitrogen, Phosphorus and Potassium content at tillering, jointing and at harvesting stage (grains and straw) over the control plot.
