Abstract
ABSTRACT An experiment was conducted to evaluate the performance of wheat varieties under different levels of nitrogen at Agronomy Research Farm, The University of Agriculture Peshawar Pakistan, during 2020-2021. The experiment was laid out in a Factorial Randomized Complete Block Design (RCBD) having three replications. Two wheat varieties and five levels of nitrogen were evaluated in the experiment. The size of each plot was 3 m x 3 m. Each plot was consisted of ten rows. The distance between rows was 30 cm. Results showed that wheat variety Pirsabaq-15 resulted in significantly higher number of tillers m-2 (329), increased plant height (95.9 cm), increased leaf area (26.4 cm2), produced more spike m-2 (296.6), took less days to physiological maturity (164), resulted maximum grains spike-1 (67), produced maximum 1000 grains weight (45.2 g), produced more biological and grain yield (10387 and 3884 kg ha-1) respectively, as compared to Khaista-17. Among the N levels, 200 kg N ha-1 significantly improved tillers m-2 (362), increased plant height (100.5 cm), increased leaf area (29.7 cm2), produced more spike m-2 (319), took maximum dABSTRACT An experiment was conducted to evaluate the performance of wheat varieties under different levels of nitrogen at Agronomy Research Farm, The University of Agriculture Peshawar Pakistan, during 2020-2021.

All the afore mentioned parameters showed statistically similar results to that of 160 kg N ha-1. Interaction between nitrogen levels and wheat varieties was found non-significant for all the parameters. Based on the current field experiment and conclusion wheat variety Pirsabaq-2015 and 160 kg N ha-1 are recommended for the increased of yield and yield components in the study area and for the similar environment elsewhere. ays to physiological maturity (169), resulted maximum grains spike-1 (74), produced maximum 1000 grains weight (49.7 g), produced more biological and grain yield (11098 and 4205 kg ha-1).
