Three vegetable irrigation systems, semi-closed subirrigation (seepage), fully enclosed subirrigation (seepage), and drip irrigation, were evaluated for use on sandy soils with naturally high water tables to determine comparative irrigation costs for tomato production. Investment, fixed (ownership), and variable (operating) costs were estimated for each irrigation system. The investment costs of the drip irrigation system were significantly greater than those for the semi-closed and fully enclosed irrigation systems. The variable costs, however, for the semi-closed system were considerably less than those for the fully enclosed and drip irrigation systems. The semi-closed irrigation system, therefore, was determined to be the least-cost tomato irrigation system under present fuel cost and nonlimiting water supply conditions.

The computer program Greenhouse Cost Accounting, available for DOS-based microcomputers and Macintosh computers, is described. The software enables the user to perform cost accounting and to determine the profitability of greenhouse crops. The information can be used by managers to analyze various production, financial, and marketing strategies. The Greenhouse Cost Accounting program uses cost information typically found on income statements and direct cost information for each crop. From these inputs, the program allocates as many costs as possible to individual crops. The remaining unallocated costs are assigned to each crop on a per square-foot-week basis. The computer output provides information on costs and returns on a per crop, per unit, and per square-foot basis. It also provides an income statement showing total costs, allocated costs, and unallocated costs. The output can aid the manager in making decisions about pricing, reducing unprofitable production, controlling costs, and increasing sales of profitable crops. The program also can be used by greenhouse management classes or for extension workshops.
