Effect of nitrogen and zinc sulfate fertilizers on yield and yield components of barley (Hordeum Vulgare L.)

For the purpose of study on the different levels effects of nitrogen fertilizers and zinc sulfate on seed yield and yield components of barley (figure 13 sarasari barley), the experiment was conducted to factorial based on statistical plan format of block randomized design in karun area of Khuzestan province with four replications. In this research nitrogen fertilizer in 3 levels (0,30,60 kg ha-1), and zinc sulfate fertilizer in four levels (0,10,20,30 kg ha-1) that were supply with strip application which available to crop at seeding times. The results showed that different levels of zinc sulfate and nitrogen fertilizer had significant effects on yield and yield components at one percent level. So that by using maximum nitrogen fertilizer seed produce increase to maximum (3.28 tons per hectare) and biological yield harvest index (9.34 tons in hectare), obtained by consumption of 60 kg nitrogen fertilizer per hectare. So grain performance and biological function affected by zinc sulfate as a result maximum of product of grain. (3 tons per hectare). Biological (9.19 tons per hectare) caused by usage of 30 kg zinc sulfate per hectare. Between fertilizer levels, zinc sulfate fertilizer treatment of 30 kg per hectare in terms of production numbers of seeds per yield and harvest index. The most suitable treatment known is nitrogen fertilizer also relative to non-consumption conditions caused increasing of spike per levels, seeds amount per spike and harvest index and the weight of 1000 seeds of barley.
