Synopsis: Various management practices were found to have the following effects: no significant difference in forage and root yields among 6 alfalfa varieties and between hardy and non-hardy varieties; forage production of Hubam and Madrid sweetclovers were equal; and Madison and Hairy vetch similar in forage, root, and total N production. Barley yields following alfalfas and Hubam sweetclover were similar; Madrid depressed barley yields; and the vetches were superior to all legumes in effect on barley yield.
