To identify if twin row seeding systems and adjusting seeding rate will; 1)Increase the competitive ability of wheat in weedy situations and reduce weed seed set, 2)Increase the profitability of wheat production through increased yield and reduced costs of inputs.
Magenta yeilded higher than Mace in Both seeding systems.
