Two hundred and twenty five site years of irrigated corn production experience, is analyzed here for the years 2000, 2001, 2002, 2003, 2004, and 2005. The leaf tissue nutrition and field agronomy of all sites are documented at anthesis. Cob development factors, yields, and grain quality was assessed by mid-September. Whole plant silage and/or dry matter stover, for grazing was analyzed. Over twenty varieties of the newest corn genetics are also included in this study. A strong working relationship was established with Alberta and Manitoba during the course of this corn research. On the basis of the results from this study, it was concluded that a meaningful data base and foundation for agronomic recommendations, to irrigated corn producers has been established.
