Abstract
The N content of, and accumulation in, the leaf, stem, husk and seeds of a crop of groundnuts was measured at intervals from sowing to maturity. Leaf and stem N contents decreased from early in life until seed growth started, after which they remained fairly constant until maturity. The crop accumulated 2.39 kg N/ha day during vegetative growth and 3.7 kg during the first half of reproductive growth, after which N accumulation ceased. The cessation of N accumulation coincided with the cessation of vegetative growth. A total of 30 g/m2 was accumulated by the crop and ultimately 66% of this was in the seeds. Redistributed N from the leaves was a substantial contribution to seed N
