Effect of Nano DAP on Growth and Yield Performance of Triticum aestivum (L.) East Nimar Region, Khandwa, Madhya Pradesh, India

The study was to evaluate the impact of Nano DAP on the growth and productivity of wheat (Triticum aestivum L.), specifically on the HI-1634 (Pusha Ahilya) variety, through foliar application. The experiment laid out in randomized block design (RBD) with three replications. The field experiment was carried out during the Rabi season of 2023/24 at the School of Agriculture, Research farm of DR. C.V. Raman University in Khandwa, Madhya Pradesh, India. There were seven treatments consisting of different doses of T1-100% NPK, T2-75% N and P and 100% K, T3- 50% N and P and 100% K, T4- T2 + ST with Nano DAP @ 5 ml/kg seed + FS with Nano DAP @ 2 ml/litter of water, T5-T3 + ST with Nano DAP @ 5 ml/kg seed + FS with Nano DAP @ 4 ml/liter of water, T6- T2 + ST with Nano DAP @ 5 ml/kg seed + FS with Nano DAP @ 4 ml/litter of water at and T7- Control. The findings revealed that treatmenT1 resulted in the highest number of tillers and yield, followed by T6, which significantly higher performance with the application of 100% NPK. The foliar sprays of Nano-DAP in T1 treatment showed promising outcomes in terms of tillers, grains earhead-1, spikelet earhead-1, earhead-1 length, and yield ha-1. It is evident that utilizing Nano DAP in place of half of traditional DAP, as well as treating seeds with Nano DAP, leads to superior root growth and overall crop development.
