• Abstract:

  In the municipality of Jocotepec, known for its protected agriculture focused on the main crop of raspberry, the intensive application of chemical fertilizers is causing an increase in soil salinity, thus limiting the maximum development potential of the crop. In order to investigate the potential benefits of halophilic bacteria in decreasing salinity and their biostimulant effect on the vegetative development of raspberry (Rubus idaeus L). The present investigation was established in a production unit located in the municipality of Jocotepec, Jal, where the evaluation of the effect of halophilic bacteria was carried out at a dose of 6 L1 plus a control without application, 4 applications were made in the irrigation saturating the furrow, with intervals of 7 days. The variables evaluated were: soil response time, pH, EC, salinity, temperature; plant chlorophyll measurement using a portable non-destructive measuring device (SPAD) at fruit filling; harvest number of boxes, average fruit per clamshell, Brix degrees of the fruit and yield/week. The results showed that the halophilic bacteria induced a positive response in the variables associated with the soil, such as pH, EC, salinity and temperature. The evaluated dose of 6 L/Ha proved to be statistically the best treatment.
