The Effect of Different Fertilization Methods on Some Quantitative and Qualitative Characteristics of Grapes in Qazvin

One of the most important agricultural inputs to increase production per unit area of correct use fertilizers and organic, that they are used to increase crop yield, not only in developed countries, but in the third world countries has also been successful. In order to effect fertilization methods on some quantitative and qualitative characteristics of grapes, the experimental carried out in research station Ismael Abad in the Qazvin. Treatments contain: 1-Control (the growers) 240 g urea 240 g superphosphate triple per vine, 2- Fruit set Control (20 g urea g boric acid 20 g zinc sulfate with concentration 5 per 1000 in 4000 ml of water), 3- full spraying (200g urea흍 g superphosphate triple 200g potassium sulfate magnesium sulfate g manganese sulfate 10g copper sulfate� 20 g of iron Sequestrine) with concentration 5 per 1000,4- Used as soil three of treatment the soil application fertilizer with 5 kg of rotten manure for the vine 5- the third treatment 纋ꮶ treatment (spraying soil application fertilizer fertilizer). Measured factors yield, cluster weight and lower marketable yields. The result showed that is notable application of fertilizer in increasing the quantity and quality and grape yield per hectare has increased by 95% compared to control foliar application procedure but the difference is 246% higher than the control treatment was soil application fertilizer is quite clearly and showed application method of soil application fertilizer and combining soil application fertilizer and spraying complete fertilizer on spraying methods in grape of yield.
