Effects of seed priming and Nitrogen different levels on yield and yield components of wheat in east of Golestan province

One of the parameters for obtaining high yield per unit area, is the of the rate and percent of germination and establishment of seedlings of planted seeds. Priming is one of the techniques that results in increased percent and rate of germination and emergence. To do this, response of wheat to priming and nitrogen were evaluated. In order to evaluate the response of wheat to seed priming and nitrogen  a factorial experiment was conducted arranged in an RCBD with three replications on Golcheshmeh farm (Golestan proviance) in 2015. seed priming at five levels i.e. (non-primed and primed seeds with (hydro priming, with 0.03% zinc sulfate, 2%potassium chloride (KCl) and 2% potassium nitrate (KNO3), and nitrogen as the second factor consisted of three levels: nitrogen fertilizer (from urea): 1- No nitrogen fertilizer, 2- 75 Kg.ha-1, 3- 150 Kg.ha-1, The effect of priming and nitrogen fertilizers on yield and its components were highly significant. Grain yield and its components increased with zinc sulphate priming and they increased with an increase in nitrogen level. Grain yield Increased from 4464.64 to 5830/30 kg ha-1 with priming with zinc sulfate. As well, Grain yield Increased from 3810 to 5642 kg ha-1 with Nitrogen fertilizer (150 Kg.ha-1) ).The effect of priming by nitrogen interaction was not significant on any of the traits.
