The Impact of Manganese Sulfate on Increasing Grain Yield, Protein and Manganese Content of Wheat Cultivars in Semi Arid Region

摘要

Wheat is the mostimportant staple food crop in the world. Micronutrients are vitalcomponents for balances both growth and development in plants. Anexperiment was designed in order to survey the effects of manganesesulfate on yield and quality parameters of wheat cultivars in Isfahanin 2017. A split plot layout with a randomized complete block designwith four replications was conducted. Main plots were manganese sulfate(contains 28% pure manganese) (20, 40 and 60 kg/ha), and sub-plots werewinter wheat cultivars (Pishtaz, Shiraz and Marvdasth). Manganesesulfate influence was meaningful on the number of fertile spikes, thenumber of grains in spike, a thousand grain weight, grain yield,protein and manganese contents of grain. Cultivar had significantinfluence on number of fertile spikes, a thousand grain weight, grainyield and protein content. The highest values of fertile spike, numberof grain, a thousand grain weight, harvest index, grain yield, grainprotein and the content of grain manganese was achieved in applicationof 60 kg manganese sulfate per ha. In addition, the highest number offertile spikes, number of grains per spike, grain yield and the contentof grain manganese was related to Marvdasht cultivar. On the basis ofthe results, cultivation of Marvdasht cultivar and application of 60 kgMn sulfate per ha is recommended for the semi-arid region of Isfahan.
