| Abstract | ||
| A field Experiments were carried out during two winter successive seasons 2011/2012 and 2012/2013 at Sakha Agricultural Research Station. AgriculturalResearchCenter at the north region of Delta Egypt, to illustrate the importance of studying sowing dates of some wheat cultivars. Ten cultivars of bread wheat (Sakha 93, Sakha 94, Giza 168, Misr 1, Misr 2, Gemmeiza 9, Gemmeiza 11, Sids12, Shandawel 1 and Giza 171) were sown at 20th October, 20th November and 20th December. Sowing date were separated and wheat cultivars were distributed randomly in the every experiment. The results indicated that there were significant differences among the three sowing dates for all studied traits in both seasons. Sowing on 20th October recorded the lowest days to heading and straw yield, longest time to maturity. Meanwhile, sowing on 20st November recorded the tallest plants, highest number of spikes/m2, number of grains/spike and grain yield. On the other hand, sowing on 20th December recorded the decreases in yield and increases in protein percentage. The differences among bread wheat cultivars were significant in both seasons. Misr 2 recorded the highest number of days to heading and maturity. Sakha 94 recorded the highest number of tillers/m2. Giza 171 produced the highest values for 1000- grain weight. Misr 2 and Sakha 94 recorded the highest number of grains/spike and straw yield. Meanwhile, Misr 1 and Gemmeiza 9 recorded the highest grain and straw yields/Fed. Giza 168 recorded the highest values for both of harvest index and protein percentage. Sakha 94 recorded the highest number of days to heading and maturity and plant height when sowing on 20 November. Gemmeiza 11and Giza 171 recorded the highest values for 1000- grain weight in two seasons when sowing on 20 November. It can be concluded that sowing Giza 168 and Misr 1 on different sowing dates, sowing Gimaza 9, Gemmeiza 11, Shandaweel 1 and Giza 171 on optimum date and sowing Misr 2 on the late date are recommended for optimum grain at Kafr elsheikh area. | ||
