Improving the Growth of Fennel Plant Grown under Salinity Stress using some Biostimulants
Gehan G. Mostafa

Abstract:
The efficiency of some biostimulants, as natural and safe compounds for humans and environment, were studied on alleviation the adverse effect of salinity on Foeniculum vulgare (fennel). Seaweed extract (1.5, 3 and 4.5 cm L–1), amino acids (1, 2 and 3 cm L–1) and dry yeast (5, 10, 15, 20 and 25 g L–1) were used, as foliar application. Humic acid (1, 2 and 3 g L–1) was used, as foliar application and soil drench. Humic acid at 3 g L–1 increased significantly most of the studied traits, when added as a soil application. Most of the studied traits increased gradually with increasing the concentration of dry yeast. The concentrations of dry yeast (20 and 25 g L–1) were the most effective treatments, as compared with other studied-substances for overcoming the negative effect of salinity. Enhancing plant growth under salinity stress, was combined with increasing the accumulation of potassium and reducing the sodium ions.
