| dc.description.abstract | The present study was carried out during Kharif season of 2017 and 2019 at Norman E. Borlaug Crop Research Centre, G.B. Pant University of Agriculture and Technology, Pantnagar, district Udham Singh Nagar, Uttarakhand, India representing the Tarai belt of Uttarakhand to study the effect of different tillage methods and earthing up practices on growth, productivity, profitability and nutrient use efficiency of maize crop. The soil of the experimental site was silty clay loam having soil pH 7.19, organic carbon 0.70 % and 233.9, 20.7 and 212.4 kg/ha available N, P2O5 and K2O, respectively. The experiment was laid out in split plot design with 15 treatment combinations. There were 3 tillage methods i.e. conventional tillage, minimum tillage and deep tillage in the main plot and 5 earthing up practices i.e. earthing by pant fertilizer band placement cum earthing machine, earthing by earther, manual earthing, earthing by cultivator and no earthing in the sub plots. The experiment was replicated thrice and maize crop was gown as per recommended package of practices. The different tillage methods had significant effect on growth, yield attributes, yield, N, P and K content and its uptake and economics of maize crop. Significantly higher values of growth attributes of maize were recorded in deep tillage treatment. The deep tillage recorded 9 % higher grain yield as compared to conventional tillage treatment and 20 % higher as compared to minimum tillage. It has also recorded significantly highest value of gross return, net return and B:C ratio as compared to conventional and minimum tillage. The different earthing up practices has also significantly affected the growth, yield attributes, yield, N, P and K content and its uptake and economics of maize crop. The significantly higher values of growth attributes of maize were recorded in treatment earthing by pant fertilizer band placement cum earthing machine. The treatment earthing by pant fertilizer band placement cum earthing machine recorded 9.25 % higher grain yield as compared to earthing by earther, 20.65 % higher than manual earthing, 22 % higher than earthing by cultivator and 36 % higher than no earthing treatment. It has also recorded significantly highest value of gross return, net return and B:C ratio as compared to other earthing up treatments. The nutrient use efficiency of maize was also higher in deep tillage and earthing by pant fertilizer band placement cum earthing machine treatment. It is therefore concluded that maize crop may be grown under deep tillage treatment along with earthing up by pant fertilizer band placement cum earthing machine for higher productivity, profitability and nutrient use efficiency in Tarai region of Uttarakhand and also be replicated in whole Indo Gangetic plains of India. | en_US |
