The effect of fertilization with different nitrogen doses (0, 1.35 and 1.80 g N per plant) and different harvest times (beginning of blooming and in full bloom) on the content of chlorophyll a and b, carotenoids and anthocyanins in the leaves of sweet basil "Wala" and "Dark Opal" were investigated. It has been found that the level of nitrogen fertilization as well as the harvest time and the cultivar have a significant effect on the content of chloroplast pigments, but they exert no influence on the synthesis of anthocyanins. The highest leaf yield was obtained in the case of later harvest and with the use of 1.35 g N per plant (0.9+0.45)
