AbstractA field trial was conducted during winter season of (2004 / 2005) in Al-Jazeera / Al-Hamdhiya / Anbar province in loam soil to study the response of six cultivars of barley (Samir, Shua'a, Twaitha, Warka, Aml and Al-Hadra) to planting dates. The studied traits were no.tilleres, plant height, no.plants / plot, no.leaves, leaf area (cm2), dry weight (g) and flag leaf area (cm2). The experiment was arranged according to split plots desing with six replicates, including planting dates as main plots and cultivars as sub-plots. The experiment was statistically analysed according to analysis of variance and LSD was used for comparing means at probability of 5%. The following results were obtained:
The first date (15 / 11 / 2004) was superior in all studied traits except no.plant / plot which is not significantly different as compared with the second date . The mean results were 24.80, 103.76, 6.65, 45.50 cm2, 1.53g and 26.30 for no.sprouts / plant, plant height, no. leaves, leaf area, dry weight and flag leaf area, respectiveiy.
Warka cultivar was superior in no.sprouts, plant height (cm) and leaf area (cm2), which were 33.60, 107.87, and 49.22 respectively. Aml cultivar was superior in no.leaves, no.plants / plot and dry weight (g) which were 7.03, 54.25 nd 136.61 g, respectively, while "shua'a" cultivar was superior in flag leaf area which was 27.18cm2 .
