Abstract | ||||
Two experiments were carried out at Central Laboratory for Agricultural Climate (CLAC), Agricultural Research Centre, Dokki, Giza governorate, Egypt during two successive seasons of 2012 and 2013, to investigate the influence of humic acid, magnetite and their interactions on growth characters (plant height, number of branches, leaf area and leaves number), yield of fresh and dry herb, oil yield and its components as well as chemical composition of basil plants growing under different levels of chemical fertilizer (0, 50,100% NPK). The obtained results showed that using magnetite and humic acid under fertilization of full dose of NPK increased all growth parameters (plant height, number of branches, leaf area, leaves number, herb fresh and air dry weights) and oil percentage in herb compared to the other treatments. In addition, basil plants treated with this integrated treatment gave the highest number of yield of plants compared to the other treatments. further, using magnetite and humic acid under half dose of NPK conditions significantly increased all data collected over the control treatment (plant received only the full recommended dose of NPK ). It could be concluded that using magnetite and humic acid might improve nutritional status of plants, leading to higher plant productivity. | ||||
