| Abstract | ||||
| The present work was conducted during two successive seasons of 1999 and 2000 at the Agricultural Research Slation otking Abdulaziz Univ. at Hoda AI-Sham area. Saudi Arabia to sludy the effect of using five levels of potassium (0.0, 18.0,36.0, 54.0 and 72.0 kg Klfed) andlor three concentrations of yeast (0.0, 0.2 alld 0.4%) on plant height, number of branches and fruits per plant. fresh and dry weights of leaves, stem, roots, sepals and fruits, anthocyanines and navones 01 Hibiscus sabdarjffa L plants irrigated with saline groundwater {EC. 2.44 dSm'\ Soil application of K and spraying yeast were done three times at 45,90 and 135 days from sowing. Results showed that using K and yeast was very effective in enhancing all growth criteria, anthocyanine and navones compared to untreated and Irrigated with saline water plants. The promotion on the studied parameters was associated with increasing K levels from 0.0 to 72.0 kg/fed and Yeast concentrations from 0.0 to 0.4% .Meaningless increase of the investigated characters was observed between the higher two doses of K and the higher two concentrations of yeast. One can slate thai supplying Hibiscus sltbdarjffa plants grown under saline conditions with K al54 kg/fed incorporated with spraying 0.2% yeast three times was necessary for alleviating the adverse effects of watei salinUy on growth traits and chemical constituents. | ||||
