Abstract
Seeds of (M&na and Horus) sorghum hybrids were sown on i st June if) 2001 and 2D02 seasons at Ras Seer Experimental Statioo - Desert Research Cent6r (DR C) - South Sinla Governorate. Three different wells containing throe different levels of 'sallne water (2970. <1580 and 9350 ppm) were used In irrigation. Sulfur fertilizer was added at rates of 150. 300 and 450 kg I fed. Results revealed that grain yie'd reduced by 14.2% with ·.vater sali(\lty 4580 ppm and by 34.5% when salinity increased 10 9350 ppm. On the other hand. lodder yield decreased only by 3.1 300 10.8% at the same levels of salinity respectlvely. These findings illustrate that fodder yic!d was less anecrec by s.aJ1nity while the dramatic aHect of salinity was Observed in grain yield. Hybrid Horus show superiority in salinity tolerant compared wllh ~"ena hybrid. All recorded characters of Horus hybrid showed signl~C<lnt IncreaSIng more than Mena hybrid. Superiority of Horus reached a percenlage of 18.4% and 5.5% for grain and fodder yields respectively. Grain yield increased by 39.3~% and 202%. while ladder yield tncreaseo by 8.89% and 6.00% as sulfur lertllizer ir.creasec trom 150 to 300 kglfed. and 450 kg/fed. respectively. The greatest 9rilln and fodder Yields were Obtained of hybrid Horus under the lowest sal! concentration (2970 ppm). The most pronounced values or growth and yield were observed when Ihe maxrmurn sulfur fer1ilizer (450 kg/fed) and water contained tha lowest salt conc. (~70 ppm)were used. The higher gr-ain yield was obtained of Horus hybrid received 450 kg SHed. It IS noUceabte th.at 'he reduction occurred in rodder yield of hybrid Horus Clpplied with 4SO kgffed due to increasing salt concsnlranon up 10 4580 ppm and 9350 ppm was little (8. f and 6.5% rssoecuvetv) and could be acceptable under condition 01 Ras Sedr. whereas. water available always contain high sart concentration. trus IIIUe reouction may no! cause ecooornicat losses in fodder yield. On the other hand. redocton occurred in grain yield was detectable (8.1 and 23.7% respectively) when high sail concenuauoo (4580 and 9350 ppm) were used.
