Impact of Nano-fertilizers on Productivity and Profitability of Wheat (Triticum aestivum L.)

Yield stagnation, multi-nutrient deficiencies coupled with reduced fertilizer-use efficiency have emerged as major challenges to the food-systems of South Asia. Modern scientific tools to enhance nutrient use efficiencies along with augmented crop yields became utmost necessity to sustain food security of developing world. In this context, a field study was undertaken to understand the influence of numerous nano-fertilizers on wheat productivity, profitability and nutrient-use efficiency. Results revealed that application of 100% NPK coupled with foliar-spray of Nano- N + P + K + Zn increased grain and straw yield by 29.8 % and 13.7 %, respectively over 100% NPK. The crop fetched a net return of ₹ 72141.50 with B:C ratio of 5.51 with 75% NPK + nano-N. As a result, the wheat crop produced when Nano-N + 75% NPK was applied produced a greater yield (grain, straw, and biological), as well as financial gains.
