Abstract
The response of hydroponically grown tomatoes (Lycopersicon esculentum) to stem and fruit pruning was investigated in a shade net structure. Plants were pruned to either one or two stems, with three fruit pruning treatments (six or four fruits per truss, as well as no fruit removal). Plants pruned to two stems resulted in a significant increase in total and marketable yield, with a decrease in unmarketable yield. Although the fruit pruning treatments had no significant effect on marketable yield, zero fruit pruning increased the total number and mass of small fruits. Plants pruned to two stems yielded a higher number of fruits per plant, while the competition for assimilates lead to reduced fruit size. The increased incidence of cracking with the single stem pruning can be related to the larger fruit size obtained with this treatment. The study demonstrated that yield and fruit size can be effectively manipulated by stem pruning, while fruit pruning has only a limited effect.
