Abstract

In the single truss tomato production system (STTPS), plants are grown hydroponically in a greenhouse with a single cluster of fruit per plant. One major advantage of STTPS is the ability to achieve uniform fruit quality on a planned schedule with predictable yield. To achieve high levels of greenhouse space utilization and a consistent harvest, several generations of plants are grown simultaneously with the plants being spaced periodically to maintain maximum plant canopy cover of the growing area, thereby maximizing utilization of space and supplemental lighting. As the production period varies with the light received by the crop it is essential to control the amount of supplemental light provided the crops so that each will have a predictable harvest date. Simulation of the cropping cycle has been programmed in Visual Basic to provide a management tool for the scheduling of lighting and the design of the lighting system. This program is based on a previously determined relationship between light received by the crop between germination and first flower development and the time to harvest. It accepts location specific solar radiation data as a variable input and has been used to optimize scheduling for the New Brunswick, New Jersey location.
