Abstract

The objective of this study was to verify the viability of the co-inoculation of caupi seeds (Vigna unguiculata (L.) Walp.) with nitrogen fixing bacteria of Bradyrhizobium sp. (BR-2001 and NFB-700) and Paenibacillus polymyxa [(Loutit (L.)] strains and their efficiency in calcium, iron, and phosphorus absorption by caupi plants under different inoculation methods. A Yellow Argisol was collected in February, 2002, located at the km 53 of BR 101 North highway, latitude 07ºSouth34'00'', longitude 35ºWest00'00'' and altitude 14m, in Itapirema (Goiana, Pernambuco State, Brazil). The inoculations were made in seeds and soil to a depth of 3.5 cm using IPA-205 cultivar. The variables evaluated were calcium, iron, and phosphorus concentration in the aerial part dry matter. The co-inoculation of caupi with strains of Bradyrhizobium sp. introduced in the soil provided calcium, iron, and phosphorus concentration increase.
