A field experiment was conducted on experimental field of S. K. N. College of Agriculture, Jobner, during kharif 2017 to work out the effect of different stress mitigating chemicals on productivity of clusterbean [Cyamopsis tetragonoloba (L.) Taub] varieties. The treatments consisted of combinations of four varietites (RGC-1003, RGC-1033, RGC-1038 and RGC-1055) and five stress mitigating chemicals (Control, Thiourea, Thioglycolic acid, Salicylic acid and Muriate of Potash) were tested in Randomised Block Design with three replications. Results revealed that variety RGC-1033 proved significantly superior to variety RGC- 1003, RGC- 1038 and RGC- 1055 in respect of number of total and effective root nodules and dry weight of total and effective root nodules. Similarly the seed yield (1469 kg/ha), stover yield (3266 kg/ha) and biological yield (4735 kg/ha) were also significantly higher with variety RGC-1033. A significant increase in N, P and K concentration in seed and straw and their total uptake, protein content (27.43 %) were recorded in variety ‘RGC- 1033’ and proved best and economically profitable as compared to other varieties. Results also showed that application on 500 ppm thiourea at branching and flowering stage significantly increased the number of total and effective root nodules and their dry weight, protein content (27.4 %) stover and biological yield (1369, 3106 and 4475 kg/ha) and proved economically beneficial as compared to control. However, spray of thioglycolic acid @ 100 ppm at branching and flowering recorded at par net returns with foliar application of thiourea @ 500 ppm.
