| Abstract | ||||
| The Field experiments were conducted out during the two successive winter seasons of 2012/2013 and 2013/2014 at the Experimental Farm (Demo) of the Faculty of Agriculture, at Fayoum University , Egypt .The aim of these experiments was to evaluate growth character of some wheat cultivars under different sowing dates and different irrigation intervals . The experiment was laid out in split - split plot design with four replicates and comprised of three dates of sowing, namely 1st November, 15th November and 30th November in main plots and three irrigation intervals, namely, Irrigation every 21(I1) days, Irrigation every 28 (I2)days, Irrigation every 35( I3)days, in sub- plots and three wheat cultivars namely, Sakha 93, Sakha 94, and Sids 12 in subsub-plots. Results showed that the Wheat cultivars significantly differed in all growth characters. Sids 12 cultivar surpassed the other varieties in all characters under this study. On the other hand, significant differences were observed among irrigation intervals for plant height and number of leaf per plant at ripping stage, while dry weight per plant and leaves area /plant at two growth stages. Moreover the greatest value were obtained by irrigation every 21 days. sowing dates shown significant effect on plant height, number of leaf per plant, dry weight per plant, leaves area /plant at flowering and ripping stages as well as crop growth rate and relative growth rate. Late sowing date (30th November ) gave higher values from dry weight/plant and leaf area/plant at flowering stage and highest number of leaves/plant at two growth stages also high crop growth rate and relative growth rate while moderate sowing date (15th November ) gave the highest values from plant height at two growth stages, big leaf area per plant and dry weight per plant at ripping stage only. Significant differences were observed among sowing dates with irrigation intervals, sowing dates with wheat varieties, irrigation intervals with wheat varieties and sowing date x irrigation intervals x wheat variety interactions on most growth traits. The results showed that early sowing date followed by moderate sowing date under irrigation every 21 or 28 days with Sids 12 variety gave the highest values for most growth characters. | ||||
