| Abstract | ||
| A factorial field experiment was conducted in the fields of the college of agriculture / Tikrit university in sandy loam texture soil by using (RCBD) to study the effect of potash fertilizer and the type, source of zinc in the grain yield of wheat. The experiment included two factors the first potassium fertilizer was four levels (0, 80, 160 , 240) Kg K ha-1 as potassium sulphate and the second factor is zinc fertilizer added from two sorouce: the mineral zinc sulphate ZnSO4.7H2O and chelate zinc Zn-EDTA with by five levels of the two fertilizers: control(Zn0) , (10 , 20) Kg mineral zinc ha-1 and (10, 20) Kg chelate zinc ha-1. The results showed that the addation of potassium fertilizer recorded a significantly increased in all the components of the yield and the highest yield for grain and straw (3850.93, 5861.5) Kg ha-1 respectively, also the zinc fertilizer was significant effect which was gave the highest yield of grain and straw reached (3823.83, 5420.8) Kg ha-1. The interaction between potassium and zinc also gave the highest yield for each of them (4909.67, 7315.7) Kg ha-1 to the treatment K2Zn4. The increase in grain yield firstly resulted from the characteristic of the number of grains spike-1 (53.23) grain spike-1 , and in secondly from the characteristic of the number of spikes m-2 and which was (426.33) spike m-1 and the weight of 100 grains (40.73) gm. | ||
