Location Summary

Conditions were poor throughout the early-growing season due to high moisture and cool temperatures. Stand count was poor due to these conditions in irrigated (I), and non-irrigated (NI) tests. The dry conditions during the month of July had a significant affect on yield in the non-irrigated variety test.
