The long fight with Mother Nature that started in the fall with harvest rolled right into spring and never really relented. As a result, the growing season of 2019 started out by challenging the plans that growers and agronomists had developed over the winter months to produce the highest yields possible while striving for the best return per acre. While most of those plans did not include a mid- to late-May and into June planting dates for corn and soybeans, that is when some growers finally found a dry period to put crops in the ground. Now is the time to reexamine those plans to see which of the yield determining factors could still have a positive influence on the corn crop in 2019.
After all, according to Dr. Bob Nielson from Purdue University only “12 to 16% of the overall yield variability is actually impacted by the delayed planting date.” There is still a very high percentage of the overall yield that we can influence.… Continue readingRead More »
