Biofertilization of topinambur with Azospirillum brasilense and native mycorrhical fungi, cultivated in the Central Valley of Catamarca, Argentina

To evaluate the effect of Azospirillum and mycorrhizal soil fungi on nutrition Jerusalem artichoke crop (Helianthus tuberosus L.), determinations agronomic parameters health status plants were carried out under field conditions. The tests out, at time implantation culture: "seeds" inoculated with A. brasilense native fungi, generating four treatments including control co-inoculation consortium microorganisms study (T0: or uninoculated control; T1: inoculation brasilense; T2: T3: joint fungi). results indicate that significantly increased plant growth in height, leaf area, biomass, dry matter, yields. It was determined application selected has a promoting growth, increasing productivity topinambur
