Location Summary

Rainfall was below normal for May and June. Sufficient rainfall was received just after planting to insure good germination, but then turned dry for a period which lasted from mid-May to mid-July with only light rains. Rains beginning in mid-July and continuing through the first part of September were very beneficial to later maturing varieties. Temperatures were not extremely hot during the growing season.
