SUMMARY
The influence of the rate of fertilizer on tomatoes fruit quality aspects such as taste and content of nutritionally important compounds were investigated in this paper. The tomatoes were analyzed for sugar content, titrable acidity, vitamin C (ascorbic acid), lycopene, phenolic compounds and total antioxidant activity by FRAP. The experience was done in a cambic cernosium soil, with low acidity reaction and the high natural fertility potential favorable vegetables cultivation. The study was performed on control soil samples (without fertilizers) and soil samples after differentiated NPK fertilization in variable doses: N30P30K30, N45P45K45, N60P60K60, N120P60K60. The fertilization doses and the application methods in tomatoes fertilization were to determine in correlations between agro chemistry factors.A field experiment was using tomatoes samples in different precocity steady: early (Export II) and middle tardy ( Campbell 1327).The NPK fertilization doses were affect the quality of tomatoes fruit.
