In the single-truss system of tomato growing, the main shoot is pinched, leaving a few leaves above the first truss, and only the first truss is harvested. The objective of this system is to reduce labor requirement for training, pruning and harvesting. Workplace ergonomics is markedly improved by the use of high benches. There is no need for skillful plant operations. Soilless culture is required for the system, because several replantings are performed in a year. A “wet-sheet culture” system has been developed, in which a water-retaining sheet made of non-woven fabric is used as a growing medium. Fruit quality can be easily improved by the application of salinity stress. A large number of nursery plants are required in the single-truss system because of the dense planting and frequent replantings. Mass production of nursery plants in plug trays is recommended. In the single-truss system, no serious problems occurred even when very young plug seedlings were transplanted. An alternative way might be the use of cuttings. The roots of tomato plant cuttings emerge easily if the cuttings are placed in a medium such as rockwool. The single-truss system may be suitable for large-scale production of tomato. Continuous predictable production may be possible if the environment in the greenhouse could be adequately controlled.
