Abstract
The study was carried out in the winter (rabi) season to determine effect of Nano and Non-nano nutrient, the study's findings revealed that wheat grown with 100% NPK + nano nutrients (N + P + K + Zn) had significantly higher uptake, namely N (143.1 kg ha-1), P (28.9 kg ha-1), K (109.0 kg ha-1), and Zn (519.5 g ha-1). Applications of nano nutrients—N, P, K, and Zn, and N + P + K + Zn + 75% NPK—worked synergistically and increased content and uptake over 100% NPK. Similarly, the agronomic efficiency (kg of grain kg-1 of nutrient applied) of N (22.4), P (56.0), and K (84.0) was greatest when 75% NPK + nano N + bio nano P, K, and Zn were applied. In a similar manner, physiological efficiency and partial factor productivity were also found to be significantly higher with the same treatment. Thus, the wheat crop grown with the application of Nano-N + 75 and 100 percent NPK led to higher nutrient content, accumulation, and efficiency.
