Abstract: 

In order to study the effects of manganese sulphate on yield, yield components, and grain quality of wheat cultivars, an experiment was conducted in a split plot layout within a randomized complete block design with four replicates in Abadeh region during 2007-2008. Main plot was manganese sulphate (0, 20 and 40 kg h-1) and subplot was winter wheat cultivar (including Marvdasht, Shiraz and Pishtaz).The results showed that increasing the manganese sulphate levels causes meaningful increasing in the total plant dry weight in stemming, pollination and physiologial maturity period and also increasing number of fertile heads m-2, kernel number per fertile head, 1000-kernel weight, grain yield, and grain manganese and grain protein and decreasing infertile heads. Studied cultivars had significant differences with each other from vegetative growth and yield components and grain yield so that Marvdasht cultivar meaningfully had the highest dry matter during stemming, pollination and physiological maturity period in comparison with other cultivars and also had more vegetative growth. Also from yield components including number of fertile spike m-2, number of kernel in fertile spike and following this, Marvdasht kernel yield was the best cultivar, and had the highest grain manganese. And Pishtaz cultivar from total dry matter, yield components and grain yield was in second place after Marvdasht cultivar and had only the highest 1000-kernel weight. Shiraz cultivar had the least yielding rate from growth and yield indices and was the best cultivar from seed protein. Based on these results, it seemed appropriate to use 40 kg ha-1 manganese sulphate and Marvdasht cultivar to produce wheat under conditions similar to current study.
