dc.description.abstractIt is well known that biotic and abiotic factors that affect lettuce growth influence pigmentation, phytochemicals and nitrate concentration. In this study, the effect of organic and inorganic fertilizers (T) on pigments, phytochemicals and nitrate concentrations of red and green lettuce was investigated. Information on the effects of cultivar (C), T and their interactions will inform future selection strategies for the production of low-nitrate cultivars. The results indicated that C significantly affected pigment, phytochemicals and nitrate concentration. The effect of T was significant on chlorophylls and nitrate concentration of the red and green lettuce. Analyses of variance showed that CxT was significant for anthocyanin, phytochemicals and nitrate. The results also indicated that green and red varieties responded differently to the fertilizer sources. The green cultivar showed larger differences than the red cultivars. Also, the cultivar that had the highest anthocyanin content accumulated higher nitrate concentration than the others. To determine whether colour influences the nitrate accumulation, further study has to be conducted with more red and green varieties in controlled environments. Consequently, to minimize the risk associated with high concentrations of nitrate in plants or ground water, it is necessary to optimize the cultivar selection, fertilizer source and amount of nutrient applied to the crop.
