Response of wheat to foliar application of nutrients under different dates of sowing

A.H. Pavithra, B.N. Patil

Abstract


A field experiment was conducted at University of Agricultural Sciences, Dharwad on medium black soil during rabi season of 2011-12 to study the response of wheat to foliar application of nutrients under different dates of sowing. Among different treatments , foliar application of Starter @ 2% at 15 and 45 DAS + Booster @ 2% at 55 and 70 DAS recorded significantly higher yield components like effective tillers per square meter, number of grains per ear head,1000-grain weight (43.10 g), grain yield (39.97 q ha-1) and quality parameters i.e. protein, gluten, starch, zeleny, zinc content in wheat grains. This treatment also recorded higher nutrient uptake at harvest and higher net returns as compared to control treatment. Among the interaction effects, foliar application of Starter @ 2% at 15 and 45 DAS +Booster @ 2% at 55 and 70 DAS in timely sowing recorded significantly higher yield and yield components like effective tillers per square meter, number of grains per ear head, thousand grain weight (g), grain yield (40.97 q ha-1) and its quality parameters i.e. protein, gluten, starch, zeleny and zinc content in wheat grain. The effectiveness of foliar nutrients was more conspicuous under late sown condition.
