Abstract
A field experiment was conducted on sandy loam soil at Crop Research Centre of Sardar Vallabhbhai Patel University of Agriculture & Technology, Meerut, Uttar Pradesh during rabi season (December 2018 to April 2019) in randomised block design with three replications. The treatments comprised of twelve tillage crop establishment methods were used for the experimentation and different observations were recorded during the crop growth period. The results indicated that the growth characters of wheat were significantly higher under wide raised bed residue retention (T9) except narrow raised bed residue retention (T7) and conventional tillage residue incorporation (T11) compared to other treatments. The grain yield, biological yield, harvest Index, yield attributes and grain weight were higher in treatments T9, T7, and T11, respectively. The improvement in grain yield with the tune of 32.09%, 28.14% and 25.49% was under treatments T9, T7 and T11 as compared to T12. It can be concluded that among crop establishment methods, wide raised bed residue retention (T9) found excellent to increase growth, yield attributes and yield for sustainability of wheat crop.
