| Abstract | ||||
| The present work was conducted during two successive seasons of 1999 and 2000 at the Agricultural Research Station or kIng Abdulaziz Univ. at Hoda AI-Sham area, Saudi Arabia to study the effect of using1ive levels of potassium (0.0, 18.0, 36.0. 54.0 and 72.0 kg KJred) and/or three concentralionsofyeast (0.0, 0.2 and 0.4%) on plant height, number or branches and fruits per ptant, fresh and dry weights of leaves, stern, roots, sepals and fruits, anlhocyanines and f1avones of Hibiscus sabdarjffa L plants irrigated with saline groundwater (EC. 2.44 csm''), SoU appllcation or K and spraying yeasl were done three times at 45.90 and 135 days from SOwing. Results showed that usin9 K and yeast was very effective in enhancing all growth criteria, anthocyanine and ftavones compared 10 untreated and irrigated with saline water plants. The ptomotion on the studied parameters was associated with Increasing K levels from 0.0 to 72.0 kglfed and Yeast concentrations from 0.0 to 0.4% .Meaningless increase 01 the investigated characters was observed between the higher two doses of K and Ihe higher two concentrations of yeast. One can state Ihal supplying Hibiscus sttbdarjlfa plants grown under saline conditions with K al54 kglfed incorporated with spraying 0.2% yeast three times was necessary for alleviating the adverse effects of water sa Unity on growth traits and chemical constituents. | ||||
