Abstract
s. 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 suga r content, titrable acidity, vitamin C (ascorbic acid ), lycopene, phenolic compounds and total antioxida nt activity by FRAP. The experience was done in a cambic cernosium soil, with low acidity reaction and the high natural fertility potential favorable vegetables cultivatio n. The study was performed on control soil samples (without fertilizers) and soil samples after differentiated NPK fertilization in variable doses: N 30 P30 K30 , N 45 P45 K45 , N60P60 K60 , N 120 P60 K60 . The fertilization doses and the application metho ds in tomatoes fertilization were to determine in correlations between agro chemistry fa ctors. A field experiment was using tomatoes samples in di fferent precocity steady: early (Export II) and middle tardy ( Campbell 1327). The NPK fertilization doses were affect the quality of tomatoes fruit.
