An agronomic research experiment was carried outat N. E. Borlaug Crop Research Station, GBPUAT, Pantnagar, Uttarakhand during kharif, 2020 to investigate the development, productivity and profitability oftwo renowned cultivars (PS 1347 and SL 958) of soybean under foliar spray of thio-urea at three different concentrations (250, 500 and 750 ppm) at 23 and 54 DAS. The results showed that PS 1347 recorded higher plant dry weight (11.27 gplant-1 at 60 DAS and 15.59 gplant-1 at harvest), number of branches (5.98) at harvest, number of pods (82.4) at harvest, seed yield (2.15 tonnesha-1), harvest index (29.9), B:C (2.35), production efficiency (15.95 kgha-1day-1) and monetary efficiency (Rs. 356ha-1day-1) than SL 958. Amongst the concentration of thiourea, use of foliar spray of thiourea@ 750 ppm reported maximum plant height (61.2 at 60 DAS and 76.6 at harvest), dry weight (11.77 gplant-1 at 60 DAS and 16.13 gplant-1 at harvest), number of branches (6.35), number of pods (91.4), seed yield (2.22tonnesha-1), harvest index (30.2), B:C (2.39), production efficiency (16.41 kgha-1day-1) and monetary efficiency (Rs. 369ha-1day-1), which were statistically at par with the results obtained by the foliar application of 500 ppm thiourea at the same interval. However, there were no signs of significant interaction between the two factors i.e., cultivars and concentration of thiourea.
