Sensor based smart technologies can lead a way in increasing wheat production for small and marginal farmers with the save guard of sustainable environment using adequate synthetic fertilizer. Field plot experiment was conducted having conventional tillage (CT) and zero tillage (ZT) in main plots and five nutrient management viz., N1 and N2 with top dressing after and before irrigation, respectively having similar recommended dose, N3 based on Nutrient Expert tool, N4 using nutrient expert tool in combination with Green Seeker and N5 (nutrient enriched plot) in sub plots. The experiment was laid out in split plot design with three replications during the dry season of 2014-15 and 2015-16. Results indicated that across the two tillage options, the nutrient expert tool with green seeker based N application could save the N fertilizer by 30% without affecting the grain yield of wheat crop. This smart technology (N4) also increased the net return by Rs. 4643 and Rs. 10574 over the 100% and 150% recommended dose of N, respectively. Research findings strongly suggest the need of revision in current nutrient recommendations for wheat crop and aiming that nutrient expert tool and green seeker can be the viable option for higher productivity and profitability of wheat crop.
