Abstract

To exp < /strong>lore hybrid rice cultivation under Egyptian saline soils using its hybrid vigor in salinity tolerance, two field experiments were conducted under saline soil during 2005 and 2006 seasons at Research Farm of El Sirw Agriculture Research Station. Enhancing seedling vigor and salinity tolerance of hybrid rice as well as its grain yield were the main approaches during the set up of this experiment. The type of experimental soil was clayey with salinity levels of 7.5 and 7.35 dS/m in 2005 and 2006 seasons, respectively. For above mentioned purposes, the seeds of Egyptian  SK2034H rice hybrid  (Egyptian Hybrid 1) were soaked in 1-water (as a control treatment), 2- ZnSo4(2%) , 3- diammounum phosphate (DAP)(2%), 4- NaCl(1%) ,5-GA3 (120 mg/l), 6-cytokinine (75 mg/l)  and 7- Salicylic Acid  (80mg /L). The seedling vigor of SK2034H hybrid rice was measured at 30 days after sowing whereas, root and shoot traits as well as leaves and root chemical contents were estimated. Furthermore, growth and grain yield and its components were estimated. The obtained results showed that pre-sowing seed treatments were found to be significantly effective in enhancing seedling vigor of SK2034H and improved its growth and its favorable nutrient content such as N, P and K.  Therefore, the salinity withstanding of hybrid rice was raised  which resulted in proper growth and reasonable grain yield  and its components under salt stress. The most effective treatments were GA3, NaCl and Salicylic Acid. These treatments clearly demonstrated their desirable effect on seedling vigor, growth parameters and grain yield of hybrid rice under salt stress. Moreover, the all studied traits were significantly affected by the current treatments involving seedling vigor traits, rice growth traits at heading and grain yield and its components.
