AbstractThis study was conducted on peach transplants (Prunus persica Batsch) in the Technical Institute Nursery / Mosul /Iraq, during 2007 growing season ,to study the effect of sulphur and phosphorus and diameter rootstock on vegetative growth of Silver king peach cv. budded on peach seedling at different sizes rootstocks ,which was planted in black polyethylene bags ( 30x35 cm ) . The effect of rootstock diameter ,classified as large ,medium and small ( 8,7, 6 mm respectively), agriculture Sulphur and Phosphorus were studied. Three levels of sulphur (0 , 3.5 and 7gr Stransplantˉ¹) ,with three levels of Phosphorus of (0, 1 and 2gr p transplanˉ¹t) were used. The agriculture sulphur (95٪ S) was used as a source of sulphur and super phosphate (20٪P)were used as a source for Phosphorus which were incorporated with soil befor planting the transplants in a black polyethylene bags , at the on 26th January 2007. Results indicated that the diameter rootstock , sulphur , and Phosphorus and their interaction caused a significant increase in the leaves number per transplants , leaf area of transplants, transplants height, transplants diameter , number of shoots and vegetative dry weight . The best treatment as compared with the other treatments was the treatment of (7gr S transplantˉ¹ +2gr p transplantˉ¹ + large diameter) in leaves number per transplants , leaf area of transplants, diameter transplants , the treatment of (7gr S transplantˉ¹ +2gr p transplantˉ¹ + transplants medium in vegetative dry , and the treatment of (3.5gr S transplantˉ¹ +1gr p transplantˉ¹+ diameter medium in diameter transplants .
