The experiment on effect of biostimulants on economics of Dendrobium orchid var. Sonia-17 under protected cultivation was undertaken at farmer’s field, Chapparamane during 2017 to 2019. Eight biostimulants in two combinations were taken for the study and RDF (Recommended Dose of Fertilizers) was taken as control. Among the different biostimulant combinations used Biovita (Brown sea weed extract)@1.5 per cent showed maximum gross returns ( 4,67,550), net returns ( 3,01,473.4) and cost benefit ratio (1.81) compared to other treatments. While, the control recorded lower gross returns, net returns and B:C ratio ( 3,11,550, 1,53,573.4 and 0.97, respectively).
