Improving the Productivity of Fennel \Foeniculum Vulgare Miller\ Plants by Using some Humic and Salicylic Acid Treatments
2024
Overview
This investigation aims to determine the influence of humic acid and salicylic acid on the growth, yield and production of volatile oil of fennel (Foeniculum vulgare Miller). Four levels of humic acid (0, 4, 8, 12 kg/ha) were used. While foliar spraying was carried out with salicylic acid at two concentrations of 0.100, 200 and 300 ppm. The results obtained showed that humic acid at all levels, as well as foliar spraying with salicylic acid, led to a significant increase in plant productivity. The highest values for growth and productivity measurements of fennel plants were obtained when humic acid was applied at a high level (12 kg/ha). Foliar spraying with salicylic acid at a concentration of 300 ppm gave the highest values for all measurements under this study. Most of the joint coefficients showed a significant increase in all the studied traits. It was found that adding humic acid at a high rate (12 kg/ha) and foliar spraying with salicylic acid at a concentration of 300 ppm was the best treatment compared to the other combined treatments under the conditions of this study. It is worth noting that this study is primarily economic, as alternatives to expensive mineral fertilizers were used to improve the productivity of the fennel plant, which is widely used in various pharmaceutical industries.
