Effect of bio-fertilizers and bio-regulators on yield and net returns of garlic (Allium sativum L.)

Abstract

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 consisted four bio-fertilizers (Azotobacter, PGPR (Pseudomonas) and Azotobacter + PGPR (Pseudomonas) and five bio-regulators (Thiourea @ 500ppm, Thiourea @ 1000ppm, salicylic acid @ 100 ppm and mepiquat chloride @ 100 ppm). The total 20 treatment combinations were tested in split-plot design with three replications. Further, it can be concluded that combined application of Azotobacter + PGPR (Pseudomonas) along with thiourea @ 1000 ppm proved to be most superior treatment combination as it fetched comparable bulb yield (223.58 q/ha), net returns ( 1,89,332 /ha) and B: C ratio (2.40) followed by Azotobacter + PGPR (Pseudomonas) along with thiourea @ 500 ppm and Azotobacter + PGPR (Pseudomonas) along with salicylic acid @ 100 ppm.
