Response of Three Cultivars of Barley(Hordeum vulgare L.) to Different Planting Dates

The experiment was conducted in the fields of one the farmers of Al-Mussaib region (30 km north of Babylon province) During the agricultural season 2017-2018 to study the response of three cultivars of barley at different planting dates. Experimental factorial is applied according to complete randomized blocks design (R.C.B.D) which included two factors: The first factor included three cultivars of barley (Samir, Warka, Local) which symbolized by (V3, V2, V1), respectively, and the second factor included three planting dates (1 November, 15 November, 1 December) which symbolized by (D3, D2, D1 ), respectively. The average difference was measured according to the Least Significant Design (L.S.D) under the probability level of 5 % using the statistical program Genstat. The results were summarized as follows: Samir V1 was superior to the other cultivars in vegetative growth traits (plant height (cm) , tillages number, flag leaf area (cm2/plant)) and yield traits (number of spikes , Length of spike, number of grains per spike and 1000-grain weight (gm)) While the first date (1 November) D1 excelled in all studied traits except flag leaf area cm2/plant, The interaction treatment (Samir + 1 November) was excelled on all the interactions in all studied traits.
