Conteúdo: | PROFALF is an expert system used as an educational tool for extension people and the alfafa growers. It is designed to incorporate detailed information about alfafa production regarding site, soil, machinery, management levels, and yield information to simulate the annual costs and returns over the alfafa projected stand life. PROFALF is developed in a hybrid environment involving shell-baased, hypertext, and procedural computation systems providing an interactive user friendly environment. The system requires information from several domains of expertise such as Agronomy, Entomology, Agricultural Engineering, and agricultural economy. It generates a soil fertility profile from the site information and projects the annual alfafa yields based on the user's fertilitity and liming plans. It projects the annual weed and insect control costs based on typical systems plans. The users simply initiate and modify their production plans to conduct the sensitivity analysis to compare the short-term (one year) and long-term (multi-year) effects on yields, costs, and returns. The results clearly show the details contrast on the effect of having a good and a poor management practice in both fertility and pest management control which enables the users to assess expected profitability over the stand life by selecting the appropriate management plan. PROFALF is a product of the Alfafa Integrated Management (AIM) group at Oklahoma State University (OSU). The AIM group is an ad hoc committee composed of county, area, and state extension specialists and experiment station researchers. This project is funded by the USDA extension service special project grant in support of the competitiveness and profiability initiative.
