Three legumes, birdsfoot trefoil, sweetclover, and red clover, were seeded in April, 1956. Nine chemical treatments were applied to the legumes at three dates of application; (A) emergence of the legume, (B) one week after emergence of the legume, and (C) three weeks after emergence of the legume.
Notes were taken five weeks after emergence of the legume using a comparative index of herbicide injury. Care was taken to appraise injury to forbs, weedy grasses, and legumes before ascertaining which treatment had been applied to the plot.
Six weeks after treatments were applied yield data were taken by clipping a two foot by four foot quadrat from each plot. Clipped material was separated, oven dried, and weighed. Yields per acre of legumes, grasses and forbs were then determined.
