Abstract
This study was carried out at Abu-Ghuraib Agricultural Research Station during the seasons of 2002 and 2004. The experiment included 6 treatments which were the combination of 2 methods of seedling production of tomato (nursery plots and styropore tays) and 3 ages of seedling which were at 4, 6, and 8 leaves stage to study their effects on survival percentage after transplanting, vegetative growth and yield of tomato. Randomized Complete Block Design by using three replication was used. The results revealed that survival percentage of transplants increased significantly when produced in trays which were 79.2, 82.3% compared with plots treatment which gave 70.9, 75.5% during the first and second seasons respectively. In addition to that an increase in the plant height, and number of leaves was were recorded. The yield of these plants was 6.41, 6.39 ton/Donum compared with 4.45, 4.47 ton/Donum for the plants produced by using plots seedlings. On the other hand, it was found that using the seedlings which had medium age with 6 leaves were the superior than the young or old seedlings and affected significantly both plant growth and the yield production which were 6.70, 6.41 ton/Donum compared with 4.3, 4.12 ton/Donum when using the young seedlings and 5.57, 5.76 ton/Donum for old seedlings.
