molar ratio in the nutrient solution on the growth of sweet basil (O. basilicum L. cv. Genovese) grown hydroponically and
harvested at full bloom seven weeks after transplanting. In experiment 2, total nitrogen concentration was 10.0 mol m-3
. Mean values of four replicates ( SE), each consisting of four plants. Values
followed by different letters differed significantly at 5% level.
