| Abstract | ||
| The experiment was conducted at season 2010 in the research roof shade of Field Crop Department Agriculture and Forestry College Mosul University in13 liters capacity plastic pots, the research plan include study the effect of two factors: first cultivars with four levels including four barley cultivars : Raihan a six rows cv. (Cv.1) old Iraqi entrance cultivar and three new entered cultivars , BOI 182 a six rows cv. (Cv.2), BA2391 a six rows cv.(Cv.3) and Otis a two row cv.( Cv.4).The second factor was Irrigation with three levels chosen depending on 2007 season average for precipitation and distribution in Low Rainfall Area which equal (10.8 L/pot), Moderate Rainfall Area which equal (14.2L/pot) and High Rainfall Area which equal (24.5L/pot) . To study the effect of each factor and its interaction on growth , yield and its component in barley, five grains were seeded in 13 liter volume pots in a circle mediates pot diameter (18 cm) with seeding depth (3 cm), 30 mm of water was added to all pots after sowing as germination dose, the impact of interaction effect of the two factors in growth , yield and its components of barley crop were studied. The results showed that Otis cv. was superior in plant height followed by BA2391cv.. BA2391cv. also was the highest in a number of tillers , spikes / pot , grain yield , straw weight and biological weight . while all cultivars were equal in No. of grain / spike. This results caused to recommend continuing studies with cv. BA2391 because most traits values of this cv. surpassed domestic cv. Raihan . The irrigation factor has significant effect to increase all values of all the traits with increased amounts of irrigation and the highest value realized at the third level of irrigation and less value at the first level. | ||
