If establishment of a berseem that is optimum stand for green manure is most significant, oat or any other little grain crop seeded at about 1 bushel per acre will protect the young clover which help to split the soil crust. If very early forage before green manuring could be the objective, seed a mixture of 4 bu. oats and 15 lb. berseem/A. If biomass quantity is most important, make use of shortstalked, long-season oat. The same, but select a short-season, tall variety to reduce the likelihood of berseem clover interfering with grain harvest (156) if oat grain production is primary, keep oat seeding rate.
Berseem clover can also be described as a crop that is late-summer. Planted in mid-August within the Corn Belt, it will develop about 15 ins before frost, offer wintertime erosion security and quickly break down in springtime to provide N from the topgrowth and origins.
You’ll overseed berseem clover into standing small-grain plants, a method which includes worked well in a number of on-farm tests in Iowa (155). Plant the berseem as belated as three days following the grain crop germinates or after the tillering stage of winterseeded grains that are small. Work with a hefty seeding price to pay for paid down seed-soil contact. Frostseeding in late wintertime into wintertime wheat has not yet worked in a number of attempts in Pennsylvania (361) and Iowa.
