Abstract: A field experiment was conducted during the rabi season of 2014-15 in GBPU&T, Pantnagar to study the effect of different tillage and precision nutrient management on nutrient content, Nitrogen uptake, energy, economics and yield of wheat. The result revealed that among the tillage practices, there was no significant difference in grain yield but the reduced tillage produced slightly higher grain yield than conventional and zero tillage. Since it incurred a low cost of cultivation besides resulting in a marginal increase in yield attributes and grain yield, it could be preferred over the conventional tillage. The recommended dose of fertilizers recorded the highest grain and straw yield, energy use efficiency, benefit cost ratio and total N uptake more than that of the SSNM and SSNM+ Green seeker based nutrient management, but SSNM saved 37 % nitrogen as compared to the recommended NPK, which shall be helpful in to protect environment. Thus, application of the recommended dose of NPK could be made for realization of the yield potential, but SSNM could be taken as a step to make the present day agriculture eco- friendly. As the results were based on one year data, one more year of experimentation shall be made for further confirmation.
