Abstract
ABSTRACT This study aimed to investigate the interaction between nitrogen source and calcium on tomato. A soilless culture experiment was accordingly carried out using four different ratios of NO 3 :NH 4 (N1 = 1:0, N2 = 3:1, N3 = 1:1, N4 = 1:3) and three concentrations of Ca (2, 4, and 8 mmol/l) to grow the tomato fruits. The results showed that the Ca application increased the Ca levels in the fruits, yield, total amino acid, and auxin hormone of the fruits; however, Ca application decreased Pectin Methyl Esteras activity and the ABA hormone. The highest levels of nitrate and ammonium content were observed in the fruits exposed to N1 and N2 treatments, respectively. At the highest level of calcium, the fruits were more spherical, and the quality and yield of the tomato fruits were improved. The nutraceutical values of the tomato fruits, including amino acid content and composition, and the Ca level were increased, while nitrate accumulation was decreased in 8 mmol L −1 Ca and NO 3 : NH 4 (100/0).
