Engineering economy of controlled environment for greenhouse production
ABSTRACT User-friendly, menu-driven, screen-editing microcomputer software was developed to evaluate the economic feasibility of a greenhouse operation employing the single truss tomato cropping system. A variety of scenarios were investigated to determine the cost-effectiveness of supplemental lighting. The software, written in BASIC, has a generic greenhouse engineering economic analysis algorithm plus a number of supporting subprograms for calculations of costs and revenues associated with specific design/operation conditions.
