Abstract :Field experiment carried out in Falluja /Anbar/ Iraq, during the winter season 2012-2013 to determine the effect of spraying in three concentrations of salicylic acid insert ignore into journalissuearticles values(37.5, 75, 112.5); mg/L and humic acid with concentrates insert ignore into journalissuearticles values(0, 600, 800 and 1000); gr/d in growth characteristics and yield of wheat insert ignore into journalissuearticles values(eebaa99); type. In this study split plots system with Randomized complete Block, Design insert ignore into journalissuearticles values(RCBD); has been used in the experiment, the humic acid concentrations placed in the main plots and the salicylic concentrations in the sub-plots. High concentration of humic and salicylic acid showed the most significant response to most studied traits, salicylic with a concentration of 112.5 was the best in the average area of the flag leaf, number of tillers, number of spikes 448.9 Spikes/m2, the number of grains in spike 43.26 grains/plant, yield of grains 5.13 tons/H and the highest protein contents 8.23%. Wherever, 1000 gr/ D of humic acid was the earliest one to reach 100% flowering, the average area of the flag leaf, number of tillers and number of spikes 473 Spikes/m2 but did not differ significantly with level 800 gr/ D in the number of grains in spike, the yield of grains and protein contents. The Interference between concentrations of Salicylic and humic acid significantly affected most of the properties of the yield and characteristic growth.
