To evaluate sub clover varieties in a cropping system.
Key messages
Antas Sub clover (brachycalnium type) grew significantly more than other sub clovers, and more than twice the production of Trikkala (1.735t/ha DM)
The more biomass you grow, the more nitrogen you fix. Using rules of thumb (25jg/ha N per 1t DM), Antas would fix 92kg/ha of nitrogen cf 43kg/ha N for Trikkala.
A later sowing combined with a dry spring produced some variances. and lower dm yields than expected.
More work is required to show possible yields, both as monocultures and as mixes for rotational options.
