As more farms take advantage of winter forage yield and quality, the season length for corn gets squeezed. For many farms, BMR corn available today has difficulty fitting in the shorter rotations. Thus, the major increase in interest in getting the BMR advantage by planting sorghum species with their shorter season and potentially wider harvest window. The other reason farms are adding BMR sorghum to the rotation, is that the forage is perfect for optimum growth of heifers and maintaining dry cows in good but not excessive condition. This is often at a much lower cost than growing corn silage.
