in three legumes (groundnuts, cowpeas, and
soybeans) and in two cereals (sorghum and maize)
were investigated over two seasons in Alfisols with and
without N fertilization. Using the N uptake and natural
""N abundance of non-nodulating plants as the indication
of N derived from soil and fertilizer, the per
cent N derived from atmospheric N2 was calculated
for nodulated plants. In the first experiment, the
groundnut genotype contained 85% atmospherc-derived
N, but the percentage decreased with N application,
Estimates of atmosphere-derived N by the N-difference
and 15~-abundanctee chniques gave identical
results. The percentages of atmosphere-derived N estimated
by the two methods at different stages of
groundnut growth were also similar. In the second experiment,
atmosphere-derived N was estimated in
plants grown with 0-200 kg ha-' applied N. The estimated
atmosphere-derived N ranged from 42% to
61 % for groundnuts from 33% to 77% for cowpeas,
and from 24% to 48% for soybeans, depending on the
amount of N applied. Inoculation with a Bradyrhizobium
strain increased the percentage of atmospherederived
N in soybean plants grown without any fertilizer
N. The natural ""N abundance of sorghum and
maize was very close to that of the non-nodulating
groundnut, suggesting that these cereals can be used as
reference plants in the estimation of atmosphere-derived
N by the natural ""N-abundance method.","1990","published",,"Biology and Fertility of Soils","9","1","Springer Verlag",,"25-30",,,,,,,,,,,"TRUE",,"0178-2762",,,,,,"","http://dx.doi.org/10.1007/BF00335857","http://scholar.google.com/scholar?hl=en&q=Nitrogen+accumulation+in+three+legumes+and+two+cereals+with+emphasis+on+estimation+of+N2+fixation+in+the+legumes+by+the+natural15+N-abundance+technique&btnG=Search&as_sdt=0%2C5&as_ylo=&as_vis=0","author",,"","",,,,,,"",,,,,,,"",,,,,"",,,,,"","",,,,,"","",,,,,
