Abstract: A field experiment was conducted to study the effect of soil and foliar application of nitrogen and sulfur on wheat varieties during two growing seasons (2008-09 and 2009-10) at New Developmental Farm of Khyber Pukhtunkhwa Agricultural University Peshawar, Pakistan. The experimental setup was Randomized Complete Block Design with four replications. The 5 × 3 factorial experiment was designed with eight different nitrogen and sulfur treatments and were applied to main plots at four application timings (T1 = at sowing , T2 = at tillering, T3 = at anthesis and T4 = after anthesis stages). Number of spike m-2, Number of grains spike-1, 1000 grain weight and grain yields increased significantly by both N and S application methods. Wheat yield and yield components were higher when nitrogen and sulfur were applied in split doses at sowing (N @ 60 kg ha-1 + S @ 15 kg ha-1), tillering (N @ 40 kg ha-1), at anthesis (N @ 10 kg ha-1 + S @ 10 kg ha-1). It is concluded that N and S spray at the rate of 10-15% during different growth stages would improve the grain yield and yield components of wheat in the study area and contributed significantly to increased production.
