Abstract

The effect of nitrogen fertilization in various rates and the stage of plant development (beginning and full bloom) on the mass of leaves of three sweet basil cultivars (‘Dark Opal’, ‘Mittelgross’ and ‘Wala’) as well as the content of total N, chloroplast pigments and essential oil in leaves were estimated. It was found that nitrogen fertilization significantly increased the mass of leaves, the chloroplast pigment content and the yield of essential oil whereas the effect of the stage of plant development on above parameters depended on the cultivar.
