A
glasshouse experiment was conducted in order to evaluate,
using the A value method, the liming effect on the efficiency
of nitrogen symbiotic fixation (NSF) of the common bean
genotypes BAT 58, BAT 477, DOR 364 and CC 25-9 (N) in
a Rhodic Ferralsol soil. NN 125, a non nodulant common
bean, was used as the control crop. All common bean
genotypes increased the fraction of N in plant derived from
soil due to liming, mainly CC 25-9(N), that show a very low
capacity to fix N from air if the soil is not amended with lime.
Moreover, a beneficial effect of liming on the soil N pool was
found, because the increasing total N uptake by plants was
due to the N coming from the air, and the quantity of N in
plant coming from the soil diminished, mainly for DOR 364
and CC 25-9(N). In addition, the ratio %Ndff/%Ndfs, the N
percentage in plant derived from the fertilizer and derived
from the soil, respectively, vary due to the N percentage
liming. Therefore, it is necessary to use two treatments for the
control in order to evaluate accurately the NSF: with and
without the lime application. The Nitrogen Use Efficiency
parameter is disscused.
