| Abstract | A filed experiment was conducted to evaluate the effect of compost rates (0.0, 5, 10 and 15 ton/feddan), ascorbic acid concentrations (0.0, 100 and 200 ppm) on growth and productivity of dragonhead plant. These experiment was carried out during the two successive seasons of 2015/2016 and 2016/2017 at the Experimental Farm, Applied Research Center for Medicinal Plants, National Organization for Drug Control and Research, Egypt. The results showed that compost at 15 ton/feddan significantly increased each of plant height, number of branches, total fresh and dry weight per plant and per feddan as well as volatile oil percentage, volatile oil, yield (ml/plant and L/ fadden) and chlorophyll a, b and a+b of dragonhead plants. Ascorbic acid at 200 ppm significantly enhanced all the investigated parameters in both growing seasons. The interaction effects among different treatments appeared that the best results were achieved by the interaction treatment between organic fertilization of compost at 15 ton per feddan plus ascorbic acid at 200 ppm. This interaction treatment will promise in the development of sustainable dragonhead production with a limited use of external inputs. That could be used by the farmers under the same conditions because this treatment has the most profitable rate and concentration with the greatest yield advantages. |
