Abstract
Two field experiments were carried out at El-Gemmeiza Agric. Res. Station, Gharbia Governorate, during 2005 / 2006 and 2006 / 2007 seasons, to study the effect of transplanting canola seedling at different ages (30, 45 and 60 days as well as direct seeding) and preplanting soaking canola transplants, in GA3, IAA and NAA and without dipping (control treatment), on growth, yield and yield attributes of canola seeds (Srew 4). The treatment took of stages of 30 days from seeding the seeding were soaked for 24 hours just before transplanting using control without soaking. Results indicated that, the differences between transplanting treatments as well as direct seeding for number of days to 50% flowering, plant height (cm), number of branches / plant, fruiting zone length, seed yield / plant (g), 1000 – seed weight (g), seed yield kg/fad. and oil seed percentage were significant in the two seasons. Transplanting canola plants at 45 days old gave the highest values for all attributes studied in both seasons, except No. of branches/plant and oil percentage. While, transplanting after 30 days produced the highest values for number of branches / plant and seed oil percentage in the two seasons. The minimum values of the above attributes studied were obtained by sowing seed directly. IAA application significantly increased all attributes studied in first and second seasons.  Interaction between transplanting and soaking treatments showed significant increase for all attributes studied except number of branches / plant, 1000 – seed weight (g) and seed oil percentage in both seasons.
