Abstract:
The present investigation entitled “Effect of conservation tillage and precision nitrogen management techniques on soil health and soil available N, P and K in wheat in rice-wheat cropping system” study was carried out at the Crop Research Centre of Sardar Vallabhbhai Patel University of Agriculture & Technology, Meerut, (U.P.) during rabi season of 2021-22 and 2022-23. The experiment was conducted under split plot design with three replications, treatments comprising of three conservation tillage treatments {C₁-Conventional tillage (CT), C₂- Reduced tillage (RT) and C₃- Furrow irrigated raised bed (FIRB)} as main plots and four precise nitrogen treatments (N₁- Control, N₂- State recommendations, N₃- LCC based nitrogen Application and N₄- SPAD based treatments) as sub plot treatments. Among conservation tillage treatments, the maximum value of Available N, P and K in soil was observed in FIRB treatments while precision nitrogen treatments did not show statistically significant result. When soil parameters like Organic Carbon (%) (OC), pH and Electrical Conductivity (EC) was concerned it showed that precision nitrogen management resulted in better soil health parameters and reduced tillage resulted in better soil health parameters.
