Soybean research verification program weekly update – July 18, 2014
Author: Chris Grimes, Program Associate - Soybean/Wheat Verification Coordinator

Rainfall was more abundant in the southern part of the state this week. All but three of the fields in the program have reached the reproductive stage and are enjoying the mild conditions this week. Irrigation will be top priority from this point forward due to growth stage and moisture requirements. Most of the fields have been cleaned up and we are trying to get them setup for irrigation. Insect and disease pressure were light in the verification fields this week, except for Randolph.
