Analysis of variance indicated that fertilizer level affected citric, malic, tartaric and fumaric acid contents.
The interaction between varieties and fertilizer level were not significant except for oxidative potential.
K content of cv. Tenggo (2074.06 mg•kg-1DM) was higher compared to cv. Krespo (1856.06 mg•kg-1 DM). Mg and Mn contents of cv. Krespo (1.02 mg•kg-1 DM and 114.95 mg•kg-1 DM, respectively) were higher than cv. Tenggo (0.9 and 107.81 mg•kg-1 DM, respectively) as presented in Table 3.
