Soybeans have been evaluated for a second year as to their contribution to silage quality when interplanted with Zea mays. In 1974, two forage cultivars ('Black Wilson' and 'Laredo') available in the local seed trade, and 'Amsoy 71' were interplanted with a number of sorghum-sudans, grain sorghums, and Zea mays. A number of protepeas (Vigna unguiculata) were also interplanted.
