A lupin crop was sampled each week to measure nitrogen fixation by acetylene reduction assay and for determination of the total nitrogen content on the organs on each axis of the plant. Nitrogen fixation started 5 weeks after sowing, reached its maxi

Defoliation, whether by cutting or by grazing, substantially reduced nitrogen stress provided that this stress was evident before defoliation. Defoliation had little effect on the relation of nitrogen stress to the concentration of either total nitro
