Description
Data from alfalfa (Medicago sativa L.) cultivar trials in Illinois, USA from 1963 lo 1992 have been adapted to a computer software spreadsheet for storage and manipulation. The data recorded have been the percentage of check cultivar's yield. The average % of checks for a given cultivar is calculated after each year of recorded yield. The computer spreadsheet enables sorting of resultant yields. The sorting in descending order determines lhe top-performing cultivars. Criteria used lo determine cultivar suggestions for extension clienlele are: (a) a minimum of 3 harvest years in the region of cultivar suggestion, and (b) the cultivar is assured of being available in the market pince by the seed industry. Data from cultivar trials are recorded in regional files to provide site-specific cultivar suggestions and to speed lhe rate of retrieval and manipulation. The "lop len alfalfa cultivars" list is obtained for extension clientele to assist producers select high performance cultivars.
