Azospirillum brasilense in corn grown single and intercropped with Urochloa in two contrasting soils

Abstract The objective of this work was to evaluate the agronomic performance corn (Zea mays) grown single and intercropped with Urochloa ruziziensis in succession soybean (Glycine max) inoculated Bradyrhizobium japonicum, as well inoculation reinoculation Azospirillum brasilense, two contrasting soils. experiment carried out crop years, a randomized complete block design, 2x2x3 factorial arrangement, five replicates. first evalauted factor composed constrasting soils: clayey Rhodic Eutrustox sandy Haplustox. second cultivation: U. ruziziensis. third consisted onto succession, follows: no both crops, B. japonicum A. brasilense corn, + corn. In highest yields are observed soil seeds reinoculated brasilense. annual results higher grain yield intercropping soil. Inoculation reduce losses caused by competition intercropping.
