The economical development in Peru is hardly anchored to the cotton. Because it is one of the main activities in the region. Therefore, the objective of the current study was research the effect of Bacillus sp., B. yuanmingense and Azotobacter sp. strains in cotton (Gossypium barbadense L. var. Tangüis) in laboratory and field conditions. Previously isolated strains from Ica soils were used in essays. In laboratory conditions the interaction B. yuanmingense LMTR28 - Azotobacter sp. LMTZ56S4b was one of the best treatments against the control non-inoculated (N-) as it showed an improvement in fresh and dry weight of the aerial part. Additionally, in field conditions this treatment showed the highest value in plant height. Oddly, in the field, this treatment had an early flowering. Besides, the best microbial activities were obtained with the treatments with Azotobacter sp. LMTZ56S4b, B. yuanmingense LMTR28 and the interaction of both. These results showed that the former interaction has a great potential as biofertilizers.
