Midsouth Planting Date/Maturity Group Research - July 2012
Fertilization of soybeans is often required to produce maximum yields and maintain soil productivity here in Arkansas.

This project is a study to evaluate maturity group and planting date across a wide range of different latitudes. The project is funded by the Midsouth Soybean Board and the United Soybean Board in a joint project.
A goal of this research is to help farmers determine at any given day of the year for their particular location, what the best maturity group choice is for them to plant.
The experiment is located at eight different locations, spread across Arkansas, Texas, Louisiana, Mississippi, Tennessee and Missouri. In addition to looking at yield levels for this experiment, we’re very interested in helping farmers predict crop development.
Soybean is a unique crop in that it has a very wide window in which it can be planted. You can begin planting soybeans soon after the danger of frost has ended and continue in all the way to mid-June or early July. [Video shows soybean plants in a field.]
At each location we have four maturity groups: maturity groups 3, 4, 5 and 6, planted at four different planting dates from early March all the way into early June.
The information on crop phenology and crop development will also be important and it will help farmers to understand better when insecticides may be needed, when fungicides may be needed during the course of the season.
So we would like for farmers to be able to know when their soybean cultivar flowers, when it begins to set pods, when it will be mature. [Video shows soybean pods]
This information is important because it allows the farmer to schedule important farming activities for their whole farm. When equipment will be needed, when irrigation will be needed, when irrigation can be terminated and when harvest equipment is needed. [Video shows Dr. Purcell standing in a soybean field.]
