Effect of seed priming, nitrogen levels and moisture regimes on yield and yield components of wheat

Abstract

The experiment was layout at the Agronomy research farm, The University of Agriculture, Peshawar, Pakistan, in winter season 2015-16, to study the effect of moisture regimes, seed priming and nitrogen levels on yield and yield components of wheat. The experiment was consist of three factors i.e. moisture regimes (low, and high), seed priming (dry seed, water soaked seed and P-primed seed) and N levels (0, 60, and 120 kg ha^-1). The results indicated that higher moisture regime gives higher number of spike m^-2 (332), and thousand grain weight (45g), while in case of N-levels more spike m^-2(343), grains spike^-1 (49.20), thousand weight (46g), biological yield (10678 kg ha^-1) and grain yield (4433 kg ha^-1) ware recorded at 120 N kg ha^-1. In case of priming P-primed seed gives higher spike m^-2, grains spike^-1 (49.4), 1000 grains weight (45.4g), biological (9654 kg ha^-1) and grain yield (4032 kg ha^-1) followed by water soaked seeds.
