Late Planted Grain Sorghum

Posted by romeethredge on July 20, 2011

Late planted grain sorghum aka milo is an option after corn harvest or on land not yet planted or where we failed to get a stand.  It can be harvested for silage or grain. One problem is herbicides used on the first crop may hurt grain Sorghum .

Here are some keys to late planting:

Deep till if there hasn’t been any deep tillage within the last few months.

Watch for chinch bugs and lesser cornstalk borers, use insecticide treated seed if possible. During flowering stage watch for midge.

Plant 50,000 to 65,000 seeds per acre on dryland and 80,000 to 100,000 seeds per acre on irrigated land. Narrow row plantings are best 14 to 22 inches.

If you use Concept treated seed you can use metolachlor herbicide at planting. Atrazine can be used on any sorghum when it has 3 leaves.

Early cold in the fall can hurt yields and test weight and make drying in field difficult.

Dr Dewey Lee , UGA Extension scientist, has some good info concerning late planting of Grain Sorghum on his blog at this link.
