Corn – All of the Corn Verification Cooperators have done a great job being on top of irrigation this year. A few fields have received that initial irrigation while others will begin this week. The average date of the first irrigation last year in the verification program was May 27 and the average growth stage was V8. This year irrigation is starting around May 4 and the average growth stage is V5.5. The average growth stage for fields on this date in 2011 was V4.5, with one field not even planted yet! What a difference a year makes.
Grain Sorghum – The grain sorghum fields are looking good and enjoying this hot weather! The field in St Francis county needs a rain soon to help it along. The field in Desha County is recovering from the gramoxone drift and was fertilized. Irrigation is not far off for this field if it doesn’t rain.
