A field experiment was conducted at Horticulture Farm, S.K.N. College of Agriculture, Jobner (Jaipur) during Rabi season 2016-17 and 2017-2018. The experiment consisting four bio-fertilizers (control, Azotobacter, PGPR (Pseudomonas) and Azotobacter + PGPR (Pseudomonas) and five bio-regulators (control, Thiourea @ 500 ppm, Thiourea @ 1000 ppm, salicylic acid @ 100 ppm and mepiquat chloride @ 100 ppm). The total 20 treatment combinations were tested in split-plot design with three replications. It was observed that the application of bio-fertilizers, Azotobacter + PGPR (Pseudomonas) and foliar application of thiourea @ 1000 ppm to the garlic crop significantly increased the Sulphur content, nitrogen content, phosphorus content, potassium content and total soluble solids in bulb as compared to control being statistically at par with application of thiourea @ 500 ppm and salicylic acid @ 100 ppm. combined application of Azotobacter + PGPR (Pseudomonas) along with thiourea @ 1000 ppm proved to be most superior treatment combination, followed by Azotobacter + PGPR (Pseudomonas) along with thiourea @ 500 ppm and Azotobacter + PGPR (Pseudomonas) along with salicylic acid @ 100 ppm.
