Summary

Applying large dressings of fertilizer nitrogen to the seed bed lessened nodulation of spring field beans by as much as 50%.

The largest mean responses to broadcast nitrogen ranged from 1·9 cwt grain/acre in 1967 (3 cwt N/acre) to 3·1 cwt grain in 1966 (3 cwt N/acre).

About one-sixth of the nitrogen applied to beans was used by a following winter wheat at Rothamsted, one-twelfth at Woburn.

The results suggest that there is no prospect for the economic use of fertilizer nitrogen in the seed bed for spring beans.
