Abstract

The present work was conducted at the Laboratory of Horticulture Department, Faculty of Agriculture, Zagazig University during the two successive seasons of 2012and 2013. It aims to  study the effect of some nutrient solutions (150 and 300 ml/l) and humic acid (HA) concentrations (0, 100 and 200 ppm) as well as their combinations on growth characters, productivity and some chemical constituents of Ocimum basilicum L. cv. Genovese under nutrient film technique (NFT) system. The data recorded were growth characters (plant height, number of leaves/ plant, branch number/ plant, leaf area and leaf fresh and dry weight/plant), productivity (yield fresh and dry weight/ plant and (%) of oil content) and some chemical constituents (total chlorophyll, NPK and  total carbohydrates content). The obtained results came to conclusion that, using the treatment of nutrient solution at 300 ml/ l recorded significant increase in  growth characters, productivity and some chemical constituents of Ocimum basilicum L. cv. Genoveseas compared  to the other treatments (150 ml/l) under study in most cases. HA also, enhanced the efficiency of the nutrient solution and increased leaf area, number of leaves/plant and branch number/ plant.
