All demonstrations were carried to yield with a quality measurement included where possible. Demonstrations in soybeans included: herbicide burndown on no till soybeans, cruiser insecticide treated seed, soybean verification program, replicated fungicide demonstration, stinkbug control, maturity group IV variety, and a production survey. All demonstrations were carried out with producer equipment. Each demonstration was evaluated on its own merit and then combined into a county demonstration booklet. A major aspect of each demonstration was an economical ranking of each activity carried out. The verification program was used to compare Extension recommended production practices on an entire crop. The production survey was carried to insure that demonstration planned was what producers had actual issues with. Result demonstrations are an excellent way to transfer technology from a research base to Extension Clientele. Result demonstrations need to be relevant to the area so that producers will be able to use the information on their farm. To assist with the dissemination of information methods needs to be used to inform all producers of the results,, not only the producer participating in the program. This is done in Phillips County by the use of a printed demonstration book. Efforts must be made to insure quality data is gathered from these demonstrations. This includes measurement of plot size and correct weights of different treatments. Quality data will insure producers are willing to use the information gathered. By having an active result program more producers are willing to conduct activities on their farm. This increase in usage of Extension educational material has been a positive aspect of the program.
