Abstract
The study included the effect of planting system (single and double rows), plant spacing (20 and 30 cm) and shoot pruning (without pruning, pruned to three or six shoots, pruned to six shoots topped at 3rd leaf and all shoots topped at 3rd leaf) on early yield of tomato plants cv. Castlerock. Experiments were conducted during the summer season of 1993 and 1994.
                Plants grown in double rows at 20 cm spacing produced the largest early yield of total and size II (< 80 g) fruits. The highest early yield of fruits having size I (> 80 g) was likewise obtained from plants grown in double rows but at 30 cm spacing. Tomato plants grown with three shoots produced the highest early yield of total and size I fruits, and the lowest record of size II fruits. The treatment combination of planting in double rows at 20 cm spacing with plants pruned to three shoots/plant achieved the highest early yield in both seasons.
