Nitrogen Management in Late Sown Wheat (Triticum Aestivum L.)

Abstract

A field experiment entitled “Nitrogen management in late sown wheat (Triticum aestivum L.)” was conducted during rabi 2018,19 at Research Farm, Guru Kashi University, Talwandi Sabo, Bathinda (Punjab). The 50% recommended dose of nitrogen with 3% urea foliar application at tillering and earing recorded resulted in the highest growth parameters viz., plant height, dry matter, number of tillers and yield attributes viz., number of effective tillers, ear length, number of grains/ear and 1000-grain weight in late sown wheat. Nitrogen application 1/3 at sowing +1/3 at first irrigation +1/3 at second irrigation (N₅) recorded significantly higher grain yield (47.2 q/ha) of wheat than other treatments. Urea foliar application (3%) at tillering and earing with 50% recommended dose of nitrogen at sowing significantly increased the grain yield in wheat under late sown conditions. Treatment T₇: 50% recommended dose of nitrogen at sowing +3% Urea foliar application at tillering and earing recorded 41.8, 52.6 and 30.6% higher grain yield than T₁: 100% recommended dose of nitrogen (125 kg N/ha) at sowing, T₂: 75% recommended dose of nitrogen at sowing, T₃: 75% recommended dose of nitrogen at sowing +FYM 6 t/ha, respectively.
