Sudangrass as companion crop to establish alfalfa

Aurora Alaguero Cordovilla

The benefits of using a companion crop over herbicides when planting alfalfa are well known. Reduced soil erosion, higher forage yields or weed control are some examples as of why to choose this strategy over herbicides. New potential companion crops were investigated in southern Quebec in order to better tolerate dry conditions. Sudangrass hybrids are drought-tolerant grasses used in forage production and can be a good candidate to use as a companion crop.

Is BMR sorghum silage a good replacement of corn silage?

Fernando Diaz

Sorghum is a tropical grass grown primarily in semiarid and dry regions. It has become an important cereal crop because it is heat and drought tolerant. As forage, sorghum hybrids with the brown midrib (BMR) gene are becoming popular in the U.S. because their lower water requirement compared with corn. Average starch concentration in BMR sorghum silage is lower than in corn silage; however, fiber and fiber digestibility contents are very similar in these forages.
