Using of Microelements in Increasing Yield and Quality Grape

Chemical fertilizers are very important instruments for increasing and quality of agricultural products. Using of fertilizer management showed that didn’t reach to high yield levels and optimum quality on products. Using of potassium and micronutrients increasedyield and quality grape. Grape is the most products in Qazvin province. Takestan city have more than grape gardens than other cities in this province. Mean of yield is 12ton/ha which that is very low. Results showed that Sulfur microelements is significant on yield, weight of cluster, marketing, sugar percent and diameter of single grape. Using K micronutrients increased yield to 6200 kg/ha VS control. Also sugar percent of grape juice was 1.8 from this treatment VS control. Marketing is increased with micronutrients VS control. S micronutrients are increased yield per brush VS control. (70kg per brush).
