Guide Available Concerning Delayed Plantings
05/20/2015

(MO. EXTENSION)-- The University of Missouri Extension has a guide that addresses the impact of delayed planting. The Guide, g4091, is called “Corn and Soybean Replant Decisions” and can be found at the University of Missouri Extension’s website under publications.

Many growers have corn planted. Other growers; however with significant acreage and areas that has had frequent rains, have planting delays. It is hard to predict the yield potential decrease of delayed planting. However, long-term research indicates once corn planting reaches the May 21 calendar date, an 83% yield potential is expected; by May 31, it becomes 77% and June 10 it is 71%. Again, results will vary from year to year.

Regarding soybeans, a May 22 planting delay is expected to produce a 96% yield potential; May 29 it is 93%; June 19 it is 79% and July 10 it is 54%. Soybeans have a lot of flexibility for yield recovery from delayed planting.

For specific information, please check Guide g4091 on the University of Missouri Extension’s publications website.
