Abstract. This study was carried out at the Agricultural Experiment
station, KAU, Hada Al– Sham during 2007 and 2008 seasons, to study
the effects of three irrigation water salinity levels (1000, 5000 and
10,000 mg/l), three irrigation intervals and three sulphur rates on
forage yield and quality of blue panic grass. The results revealed that
decreasing water salinity or irrigation interval or increasing sulphur
rate ceased increasing forage yield and yield components of dry forage
yield /ha were 12.6, 10.3 and 8.07 t/ha under the effect of 1000, 5000
and 10,000 mg/l. As irrigation interval increased from 4 to 6 to 8 days
dry forage yield decreased from 11.4 to 10.3 to 9.27 t/ha, respectively.
Increasing sulphur rates from 0.0 to 7.5 to 15 t/ ha, increased dry
forage yield from 8.68 to 10.59 to 11.69 t/ha, respectively. Leaf
protein content increased as irrigation water salinity increased, where
protein contents were 18.94% and 20.63% under 1000 mg/l and
10.000 mg/l, respectively. As sulphur rates increased, protein content
of stems and leaves increased. Also, the interaction between the water
salinity and sulphur rates had significant effects on fresh and dry
forage yield. Also, the interaction between irrigation intervals and
sulphur rates had significant effects on dry forage yield. |
