Abstract
A field experiment was conducted at experimental farm, Department of Agronomy, Faculty of Agriculture and Veterinary Sciences, Mewar University Gangrar, Chittorgarh (Rajasthan) during Rabi season of 2024-25 to study evaluated the response of Nano DAP on growth and yield of wheat variety Raj-3077. The result revealed that the maximum plant height (40.22, 64.46 and 86.74 cm at tillering, jointing and harvest stage), number of total tillers (307), chlorophyll content (21.45), leaf area index (2.12) and yield parameter such as number of effective tillers (294), number of grains per spike (46.78), grain yield (44.25 q/ha), straw yield (59.78 q/ha) and biological yield (404.03 q/ha) with application of T10-T4 + ST with Nano DAP @ 5 ml/kg seed + first FS with Nano DAP @ 4 ml/L of water at 40 DAS and second spray – before one week of flowering stage So, it was concluded that treatment T10-T4 + ST with Nano DAP @ 5 ml/kg seed + first FS with Nano DAP @ 4 ml/L of water at 40 DAS and second spray – before one week of flowering stage was better combination of nano DAP for the higher yield of wheat.
