Rm. Piasentin et al., Study on the absorption of Fe, Mn, Mo and Zn by two cultivars of pigeonpea(Cajanus cajan, Millsp) submitted to two doses of fertilizers using INAA, J RAD NUCL, 244(2), 2000, pp. 295-297
Leaf samples of two varieties of Cajanus cajan Millsp were analysed by inst
rumental neutron activation analysis (INAA). The samples were taken from pl
ants grown under two fertilizer dose conditions, making use of the followin
g microminerals: Fe, Mn, Mo and Zn, which were applied individually to the
soil. The samples were collected in two cutting times. We verify the variat
ion in the absorption of each element, considering its availability in the
soil.
