SUMMARY
Present study was conducted at CCSHAU Regional Research Station, Bawal-123501, India, during Kharif season of 2016 to 2018. The experiment was laid out in randomized block design with twelve treatments replicated thrice. The treatments consisted of recommended dose of fertilizers {RP (20 kg N, 40 Kg P2O5 and 20 kg K2O)} alone and RDF in combination with seed soaking in thiourea (500 ppm) for 30 minutes alone and with foliar spray of NPK (20:20:20). The liquid fertilizers NPK and KNO3 at 1% each (separately) were sprayed once and twice at flowering and pod formation stage. The results revealed that two sprays of thiourea, KNO3 (13:0:45) and NPK at flowering and pod formation stage produced significantly higher seed yield (18, 17 and 22%, respectively) of cluster bean in comparison to control (RP) and were statistically at par with each other. The treatment with seed soaking in thiourea (500 ppm) for 30 minutes + two sprays of NPK at flowering and pod formation stage was found best in terms of productivity (seed yield) as well as profitability (net returns) i.e. 24 and 75% higher than control, respectively.
