Abstract: A field experiment was conducted to study the effect of bio-regulators on different yield and yield attributing characters on medium black calcareous clayey soil of Instructional Farm, Department of Agronomy, Junagadh during rabi season of 2017-18. The experiment comprising of twelve treatment combinations was laid out in randomized block design having factorial concept and replicated thrice. The treatment comprising 4 levels of thiourea (water spray, 250, 500 and 1000 ppm) and 3 levels of thioglycollic acid (water spray, 100 and 200 ppm) sprayed at tillering and flowering stages. Significantly higher number of spikes/plant, number of spikelets/spike, number of grains per spike, length of spike, test weight, grain, straw and biological yields of wheat were recorded with the increasing concentration of thiourea up to 500 ppm over water sprayed control and 250 ppm thiourea. Similarly foliar application of 100 ppm thioglycollic acid, being at par with 200 ppm TGA significantly increased all yield attributes and yields over water spray. Significantly maximum gross and net returns were obtained due to foliar application of thiourea @1000 and thioglycollic acid @ 200 ppm while higher B:C ratio was observed in foliar spray of thiourea @ 500 ppm and thioglycollic acid @100 ppm.
