Goldenberry (Physalis peruviana L.) is an alternative crop due to its adaptability and highly nutritious fruits. However, its production in soil has been little studied in Mexico. Due to current ecological challenges, it is necessary to use sustainable methods such as rhizobacteria. The objective of the research was to evaluate the effect of application of a rhizobacterial consortium on the production of two ecotypes of goldenberry under low chemical fertilization conditions (FQ). The Sacha and Chiclayo ecotypes were established and transplanted in greenhouse with natural ventilation in mulched soil and drip irrigation. The fertilization applied was FQ at 25 and 50% concentration based on Steiner solution, which was combined with a consortium of rhizobacteria (BF-UA), with a commercial biofertilizer (Bio-Organik Pseudomonas®) of Pseudomonas fluorescens (BC), both at a concentration of 1x108 CFU mL-1, and with two control treatments without rhizobacteria. The BF-UA with 50% FQ increased Sacha´s fruit weight (21.6%), as well as citric acid content (16.1%) in Chiclayo, in relation to the Chiclayo control without BF-UA. The BF-UA with 25% FQ showed an increase in vitamin C content (11.5%) compared to the control with 25% FQ of both ecotypes. The application of the rhizobacteria consortium and the 50% FQ reduction are a viable option for the sustainable production of goldenberry.
