Abstract

The research was conducted at AL-Makasem AL-khamseh Research Station in the north-west of Al- Hassakeh, Agricultural Research Center, GCSAR, Syria, during two seasons (2010/2011 and 2011/2012). An improved and local varieties of barley, drought-tolerant were grown, using sprinkler irrigation method. The experiment was designed in split design, including five levels of sprinkler irrigation as main treatment: first treatment: irrigation level (A) 100% watered when soil moisture is reduced to 70% of 90% of field capacity, second treatment: the level of irrigation (B) is given by 75% of (A), third treatment: irrigation level (C) is given by 50% of (A), fourth treatment: irrigation level (D) is given at 25% of (A), fifth treatment: irrigation level (E) depends on rainfall, and four secondary treatments which were the improved varieties of barley i.e. (Furat 3), (Furat 7), (Furat 9), and (Arabic black), with three replicates for each treatment. The results of the study showed that the control treatment (rainfed) could not reach the stage of grain production during the growing season, due to the low rainfall after tillers stage. Cultivar Furat3 surpassed significantly the other varieties in grain yield by 2177 kg /ha. The grain yield of the rainfed treatment was 34 kg /ha, while the first treatment (70% of 90% of the field capacity) achieved 3338 kg/ha, and surpassed significantly the other treatments. In terms of straw yield, the three cultivars (Furat3, Furat7 and Arabic black) showed significantly higher straw yield than Furat9, while the differences were non-significant between them. The yield of rainfed treatment reached 1787 kg/ha compared to 5852 kg/ha for the first water treatment. Furat7 and Furat3 were significantly higher in 1000 grains weight (34.9, 34 g) respectively. The control treatment of water (rainfed) achieved 23.3 g compared to 41.3 g for the first superior water treatment. There was no significant difference in the highest water treatment (100%) against the lowest water treatment (75%) in water use efficiency (kg/m3), which means that barley yield did not respond to the increase in water supply, and Furat 3 surpassed significantly the other cultivars.

Key words: Barley crop, Improved and local cultivars, Sprinkler irrigation, Reduced supplementary irrigation, yield.
