A field experiment was conducted on the experimental field of S. K. N. College of Agriculture, Jobner, to evaluate the effect of different stress mitigating chemicals on the productivity of clusterbean [Cyamopsis tetragonoloba (L.) Taub] varieties. The treatments consisted of combinations of four varieties (RGC-1003, RGC-1033, RGC-1038 and RGC-1055) and five stress mitigating chemicals (Control, Thiourea, Thioglucolic acid, Salicylic acid and Muriate of Potash). These were tested in Randomised Block Design (RBD) with three replications. Results revealed the highest N, P and K uptake (98.49, 10.89 and 46.15 kg/ha), Seed yield (1469 kg/ha), Biological yield (4735 kg/ha), stover yield (3266 kg/ha), net returns (Rs. 42204) and B:C ratio (2.80) were recorded in variety ‘RGC- 1033’ and it proved best and economically profitable as compared to other varieties. Application of 500 ppm thiourea at branching and flowering stage significantly increased the quality of seed and stover, seed yield and stover yield (1369 and 3106 kg/ha) and proved economically beneficial compared to over control. However, spray of thioglycolic acid @ 100 ppm at branching and flowering recorded at par net returns with foliar application of thiourea @ 500 ppm.
