Mean 6.6 47.5v 54.0v 119v 22.6

Means with the same letter within a column for a given measurement are not significantly different as determined by Fisher’s least significant differences (LSD, p=0.05)

Yield index was calculated from follow formula: (yield from corn+soybean)×100/45.4 (yield from corn only)

Soybean forage for monocultures was harvested at the same day as the harvest of a corn-soybean mixed crop

Soybean germplasm are presented in IT number, Chookdu 1 and Chookdu 2 are soybean cultivars for silage with corn, Kwangpyeonok is a silage corn cultivar

Mean of 13 mixed crop plantings
