4921. Oien, David. no date. Black medic information packet.. Timeless Seeds, RR 3 Box 461, Conrad, MT 59425.
This packet is sent to growers who purchase seed. The seeding rate is recommended at 8-10 lb/ac, planted 1/2" deep into a firm seedbed. Field trials have indicated successful medic establishment with barley, oats, spring wheat, and flax as nurse crops, but a second year of medic growth is then necessary for adequate seed production. On-going experiments in Montana (Jim Sims, MSU) are examining several rotations: medic-cereal, sweetclover-cereal, fallow-ceral, and continuous cereal, with different nitrogen rates. Results indicate that the green manures used 1-3" more soil moisture than the other treatments. Wheat yields after medic and sweetclover (25 bu/ac) were significantly higher than all other treatments. An herbicide screening tested a number of alfalfa herbicides on black medic. Poast, Fusilade, Treflan, and Kerb did not injure medic, while paraquat, Pursuit, and 2,4-DB ester caused minor injury. Solicam provided the best overall weed control with little injury to the medic.
