Abstract:
The present investigation entitled “Effect of conservation tillage and precise nitrogen management on growth of wheat” 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, C₂- Reduced tillage 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. The soil of the experimental site was sandy loam having low organic matter (0.43%), low in available nitrogen, low in available phosphorus and high in available potassium. The maximum values of growths attributes (plant height, number of tillers and dry matter accumulation) was recorded in furrow irrigated raised bed (FIRB) system than rest of tillage practices. Among precise nitrogen treatments, the maximum value of growth characters (plant height, number of tillers, dry matter accumulation, CGR and RGR) were noticed with application of nitrogen using SPAD meter while LCC treatments were at par with SPAD meter.
