Pooled data revealed that horticultural interventions, chemical applications and their interactions significantly affected total fruit yield, marketable fruit yield, gross return, net return and B:C ratio of pomegranate under hot arid climate. Among horticultural interventions, significantly highest marketable fruit yield, net return and B:C ratio (9.27 t/ha, 194881 Rs./ha and 2.34) was registered in withholding of irrigation during June+ pruning + thinning as against minimum recorded in control natural flowering (7.32 t/ha, 138553 Rs./ha and 1.70), respectively. Among chemical applications, significantly highest marketable fruit yield, net return, B:C ratio (9.52 t/ha, 202268 Rs./ha and 2.42) were registered in ethrel 2 ml/l + DAP 5 g/l treatment as compared to control without chemicals. Among interactions, significantly highest marketable fruit yield, net return and B:C ratio (10.90 t/ha, 242627 Rs./ha and 2.87) were registered in withholding of irrigation during June + pruning + thinning with ethrel 2 ml/l + DAP 5 g/l treatment as compared to minimum recorded in control natural flowering without chemicals (6.64 t/ha, 121644 Rs./ha and 1.57), respectively. In conclusion, withholding of irrigation during June + pruning + thinning with ethrel 2 ml/l + DAP 5 g/l treatment combination was found significantly superior over other treatments with highest marketable yield, net return and B:C ratio under hot arid climate.ICAR-CIAH, Bikane
