Abstract: The field experiment and instrument analytical method were conducted to study the effects of the Plant Nutrition on the yield and quality of tomatoes. The results showed that the yield and quality of treatment applying the Plant Nutrition were significantly higher than the treatments including applying water,Green Fenway and Nutrivant. Compared with the contrast,one single fruit weight,yield per plant,lycopene content and Vitamin C content of treatment applying the Plant Nutrition increased by 9.5%,34.5%,82.6% and 46.1% respectively. By applying the Plant Nutrition,the sugar acid ratio increased so as to improve the taste,and the nitrate content reduced to improve the fruit quality.

Key words: Plant Nutrition, tomato, yield, quality
