Abstract

A field experiment was conducted during rabi 2022-23 at Palampur to study the effects of foliar spray of nano DAP on the growth of wheat. The experiment was conducted in Randomized Complete Block Design with twelve treatments, replicated thrice. Application of 75 % NP along with seed treatment with nano – DAP and two foliar sprays of nano – DAP @ 0.4 % increased plant height by 60.49%, 38.33%, 43.79%, 40.99% and 42.59% at 30, 60, 90 DAS and at harvest compared to the control. Statistically similar results were observed with treatment 100 % NPK as well as all other treatments where either 50 or 75 % recommended NP was applied along with seed treatment and foliar application of nano – DAP. Application of 75 % NPalong with seed treatment and two foliar sprays of nano DAPenhanced crop growth rate, relative growth rate, yield attributes and ultimately increased grain yield.
