The American cultivars had lower RU-%Ndfa than the Japanese normal cultivars in each maturity group. We concluded that, under a high nitrate condition, the amount of fi xed nitrogen was smaller and RU-%Ndfa was lower in the American cultivars than in the Japanese normal cultivars, and the nodule weight in the middle growing period might contribute to these cultivar differences.
