Abstract

This study aimed to verify the responsiveness of common bean plants subjected to re-inoculation of Rhizobium in topdressing applied at different stages in edaphoclimatic conditions of the Cerrado. A randomized block design was used, with four replications: T1=uninoculated control; T2=inoculation via seed (VS); T3=VS + reinoculation at the V4 stage; T4=VS + reinoculation at the R5 stage; T5=VS + reinoculation at the R6 stage; T6=VS + reinoculation in at V4 and R5 stages; T7=VS + re-inoculation at V4 and R6 stage; T8=VS + reinoculation at R5 and R6 stages; T9=VS + reinoculation at V4, R5, and R6 stages, and T10=mineral nitrogen fertilization. Nodulation and morphological variables were evaluated at the R7 stage and agronomic variables at R9 at harvest. The use of reinoculation, in addition to inoculation, positively influenced the bean nodulation process. The morphological characteristics of the plants showed good development with the supply of N performed by inoculation and reinoculation, equivalent to the addition of mineral nitrogen fer-tilizer. Reinoculation from R5 to R7 stagesproved ineffective in supplying N to the common bean crop. Inoculation associated with reinoculation at the V4 stage provided higher yields and could replace mineral nitrogen fertilizer.
