Assessment Effect of Different Amounts of Iron and Manganese Sulfates on the Qualitative and Quantitative Yield of Wheat in South West of Iran (Ramhormoz Region)

In order to evaluate the effect of different amounts of iron and manganese sulfates on wheat yield (Chamran cultivar), a factorial experiment based a randomized complete block design with three replications. The experiment treatments consisted of different concentrations of iron sulfate (Including; zero, 1500, and 3000 grams per hectare) and manganese sulfate (Including; zero, 1500, and 3000 grams per hectare). The results showed that there was a significant difference between different levels of iron sulfate and manganese sulfate in terms of seed yield and yield components and seed protein content. As the consumption of iron and manganese sulfate increased the number of infertile spike decreased. The highest number of seeds per spike belonged to the consumption of 1500 and 3000 g per hectare iron and manganese sulfates. The treatment with the consumption of 3000 g iron and manganese sulfates in comparison to the control treatment led to the increase of 1000-seed weight as much as almost 10 g. The highest seed yield with an average of 670 g.m-2 belonged to the treatment with consumption of 3000 grams of iron and manganese sulfates. As the consumption of iron and manganese sulfates increased from zero to 3000 g per hectare, protein, the content of protein, iron and manganese of seed increased significantly. The results showed that micronutrients by improving growth conditions and influencing the seed yield components can increase the seed yield and quality to some extent. In general, it can be concluded that highest yield and yield components in this experiment belonged to the treatments with 3000 g.ha-1 iron sulfate and 3000 g.ha-1 manganese sulfate.
