Uses & Benefits

TNT® Vetch, a type of hairy vetch, has been designed for cover crop uses. It is very winter hardy legume and can withstand the harsh winters in the Midwest. Tests have shown more cold tolerance than crimson clover and winter peas.

Adaptation Zone

TNT® Vetch can be successfully grown throughout much of the United States. Virtually all of the Eastern U.S. and much of the Central Plains can grow hairy vetch without irrigation, and it can be grown with irrigation in many other areas. The northern areas can plant TNT® Vetch in the spring or fall. The southern region should only plant it in the fall.  

Planting Instructions

TNT® Vetch has various seeding rates, depending on the intended purpose of the crop. For cover crop purposes, drill at 15-20 lbs/acre (with rates as low as 10 lbs/acre) and broadcast at 20-25 lbs/acre. If the crop will be used for forage, plant heavier rates.

Hairy vetch can survive in a soil pH ranging from 5.0-7.5, although it prefers a pH of 6.0-7.0. Hairy vetch does best in lighter, well-drained soils.
