Respuesta de Glycine max a Azospirillum lipoferum y Rhizobium etli a dosis 50 % de fertilizante nitrogenado

The production of Glycine max (soybean) demands nitrogenous fertilizer (NIFE), as a NH4NO3 (ammonium nitrate) to supply its N demand, which when is applied in excess causes lost soil`s productivity. An alternative for this problem is to reduce and to optimize NIFE, with inoculants based in genus and species of plant growth promoting bacteria (PGPB). The aim of this research was to analyze G. max response to Azospirillum lipoferum and Rhizobium etli at 50% dose of NIFE. In that sense experimental was conducting by 5 treatments with NIFE at 100% and 50% doses for G. max inoculated with PGPB, response was based on its phenology: plant height (PH) and root length (RL) and its biomass: shoot fresh weight (SFW), root fresh weight (RFW), shoot dry weight (SDW), root dry weight (RDW). Experimental data were analyzed by ANOVA and Tukey HSD p
