Evaluates legume effects on spring barley in North Dakota. Legumes were either green manured, hayed, or harvested for the pulse crop in the seeding year. Green manure treatments produced unfertilized barley grain yields generally equivalent to yields following fallow, but significantly higher than yields following wheat. Yields following hairy vetch were the highest. Fertilized barley yields tended to be 12-15% higher following legumes than following wheat. Including legumes in the crop rotation increased the yield and protein concentration of the subsequent barley crop with reduced N fertilizer inputs. Green manured treatments were generally equal to fallow in grain yield.
