Abstract

Continuous use of inorganic fertilizers plays a vital role in deteriorating the soil health. Use of organic manure is the best remedy for maintaining soil quality as well as productivity and replacement of mineral fertilizers. In this context the present study entitled Effect of Organic Nutrient Sources on Soil Health and Productivity of Wheat under Rice-Wheat System was carried out during the Rabi seasons of 2017-18 at the Crop Research Centre, Chirodi farm of Sardar Vallabhbhai Patel University of Agriculture and Technology, Meerut, (Utter Pradesh), India. The experiment consisting seven treatments viz. T1= Control ( no organic manure), T2 = 10 t ha-1 Farmyard manure, T3 = 10 t ha-1 Farmyard manure + Cow urine + biofertilizer (Azotobacter), T4 = 10 t ha-1 Vermicompost (V.C.), T5 = 10 t ha-1 vermicompost (V.C.) + Cow urine + biofertilizer (Azotobacter), T6 = 7.5 t ha-1 Farmyard manure + Cow urine + biofertilizer (Azotobacter), T7 = 80 % of RDF of nitrogen through Vermicompost (V.C.) +

Keywords

Vermicompost, Azotobacter, neem cake, phosphorus, and Wheat.

Conclusion

The continuous introduction of the rice-wheat cultivation system without organic nutrient sources proved detrimental to soil health and quality. It resulted in a significant decrease in nitrogen, phosphorus and potassium from their original values in the soil. Organic manure application resulted in the most significant increase in the uptake of major nutrients. The current study showed that the application of 80% RDF of nitrogen from Vermicompost + 10% from neem cake + Azotobacter (T7) resulted in significantly higher N, P, and K uptake of the plants in the tillering, jointing, and harvesting stage over the control plot (no manure application). The present study thus indicates that a combination of 80% of RDF nitrogen from vermicompost + 10% from neem cake + Azotobacter is promising for the cultivation of Wheat.
