Abstract
The experiment was carried out (from 6th December 2013 to 20th May 2014) to study of irrigation intervals (3 and 6 days), levels of peatmoss in the sowing media (0, 6, 12 and 24%) and DAP foliar spray (the levels of 0, 1.5, 3 and 6 ml DAP.l-1) on the growth and yield of two carrot (Daucus carota L.) cultivars (Dordogene F1 and Ten Ten). Results indicated that Dordogene F1 gave the best results for the root characters, while the best results of vegetative growth were from of Ten Ten cultivar. Three days irrigation interval, 24% peatmoss and DAP levels significantly enhanced the vegetative
growth. The best interaction treatment was among Dordogene F1 with 24% peat moss, 6 ml DAP.l-1and 3 days irrigation interval for root (diameter, fresh and dry weight) and the longest root was in the same cultivar, various peatmoss and DAP levels but with 6 days irrigation interval. However, the best vegetative parameters were resulted various Ten Ten interactions with the three studied factors.
