Abstract

This experiment was carried out at Sari, Mazandaran, Iran in 2012. This experiment was done as split plot in randomized complete blocks design based three replications. Zinc fertilizer application was chosen as main plots (0, 20 and 40 kg/ha) and genotypes as sub plots (Tall cultivars: Sang Tarom and Mahalli Tarom; Short cultivars: Neda and Shiroodi). The results showed that the most panicle number per m2 and harvest index had observed in 40 kg Zn ha and the least of those was obtained in control treatment. Mahalli Tarom cultivar had the maximum panicle length and plant height, but the maximum panicle number per m2, grain yield and harvest index were produced for var. Neda and Shiroodi. The highest Zinc content in grain, zinc uptake in grain and straw, and nitrogen uptake in grain were observed in 40 kg Zn ha, as the most zinc content in straw, nitrogen content in grain and straw, and nitrogen uptake in straw were observed with application of 40 and 20 kg Zn ha. The maximum zinc content in grain and straw and zinc uptake in straw was obtained for var. Sang Tarom, but the most zinc uptake in grain and nitrogen uptake in straw had produced for var. Neda and Shiroodi. The highest nitrogen content in grain and straw and nitrogen uptake in grain was obtained for var. Shiroodi. The most zinc content in grain and straw were produced at interaction of 40 kg Zn ha and var. Sang Tarom and the highest nitrogen content in straw and nitrogen uptake in straw had produced under interaction of 20 kg Zn ha and var. Shiroodi. So according to the results 20 and 40 kg Zn ha was the best treatment.
