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 total yield and its quality of tomato plants cv. Castlerock. Experiments were conducted during the summer season of 1993 and 1994.
                Tomato plants grown in a single row at 30 cm spacing had higher total fruit yield per plant and average fruit weight than those grown in double rows at 20 cm spacing. In contrast, total yield per plot (marketable and nonmarketable) of plants grown in double rows at 20 cm spacing surpassed that of plants grown in a single row at 30 cm spacing. Likewise, fruit acidity percentage was increased by planting in double rows.
                Shoot pruning level had no significant effect on fruit yield whether per plant or per plot in most cases. However, all pruning applications tended to produce higher marketable and total yields per plot, especially pruning treatment with three shoots. On the other hand, all pruning levels improved both average fruit weight and vitamin C content compared with the unpruned control, since the highest average fruit weight resulted from plants pruned to three shoots.
                The highest total fruit yield per plot was obtained from plants grown in double rows at close spacing (20 cm) and pruned to three shoots per plant.
