Abstract:
In order to evaluate the efficacy of plant growth retardant (paclobutrazol and cycocel) and their time of application on yield and economics of marigold an investigation was carried out. The experiment was carried in two seasons i.e., years in Factorial Randomized Block Design (FRBD) with three replications having twenty one treatment combinations of two plant growth retardants with three doses each i.e. Paclobutrazol (PBZ) @ 50, 100 and 150 ppm and Cycocel (CCC) @ 500, 750 and 1000 ppm along with water spray (control) as factor A and three time of application viz., 30 DAT, 45 DAT and 30 and 45 DAT as factor B. The maximum flower yield, gross income net return and B:C ratio was noted with treatment G₃: paclobutrazol (PBZ) @ 150 ppm under during both the years (2018-19 and 2019-20) and on mean basis, respectively. The result revealed that among the time of application of plant growth retardants, treatment D₁: application at 30 DAT registered maximum flower yield, maximum gross income, net return and B:C ratio was recorded under treatment D₁:application at 30 DAT during both the years (2018-19 and 2019-20) and on mean basis, respectively.
