Abstract

Urea applied directly to the soil is mostly lost through volatilization and leaching. Foliar spraying is thus a potential method to increase the effectiveness of nitrogen utilization, which raises crop output. To ascertain the impact of various urea foliar application concentrations on triticale production and yield components, a field experiment was carried out. During the Rabi season of 2020–2021, An investigation was conducted at the Research Farm of Agriculture University Peshawar. The experiment followed a structured design with three replications of (RCBD). The factor encompassed twelve distinct foliar concentrations of urea dissolved in water. These concentrations were subsequently applied to the crop during its tillering and booting stages. The concentration levels were designated as follows: T1 (control) at 0%, T2 at 1%, T3 at 2%, T4 at 3%, T5 at 4%, T6 at 5%, T7 at 6%, T8 at 7%, T9 at 8%, T10 at 9%, T11 at 10%, and T12 at 11%. The results revealed that the maximum plant height (128.10 cm), spike length (16.80 cm), spikelets spike^-1 (28.78), grains spike^-1(63.13), 1000 grains weight (53.24 g),biological yield (12466 kg ha^-1), grain yield (5423.2 kg ha^-1), harvest index (43.50) and seed protein contents (18.11 %) were observed at 6% urea foliar application. Based on the above result it is concluded that urea foliar application @ of 6% found best to be used for improving yield without any harmful impact.
