Abstract:
An investigation was carried out to study the “Effect of spacing and growth retardants growth, flowering and seed yield of annual Chrysanthemum” The experiment was laid out in Factorial Randomized Block Design with four spacing levels 120 x 45 x 45 cm (Raised bed), 120 x 30 x 30 cm (Raised bed), 60 x 45 cm (Flatbed), 45 x 30 cm (Flatbed) and seven levels of growth retardants. Control, CCC 1000 ppm, CCC 1500 ppm, CCC 2000 ppm, MH 500 ppm, MH 750 ppm, MH 1000 ppm) twenty eight treatment combinations replicated thrice. The foliar spray of growth retardant in varying concentrations as per treatments was imposed after 30 DAT. It is evident from the experimental findings that, in terms diameter of main stem and spread of plant at 50% flowering was found highest under the treatment spacing 120 x 45 x 45 cm as well as cycocel 1000 ppm. Whereas, The flowering parameters in terms of days to first flower bud initiation was observed in the treatment spacing 120 x 30 x 30 cm as well as control treatment. Fully opening of flower from bud initiation were found earlier in the treatment spacing 120 x 45 x 45 cm as well as control treatment. The seed yield parameters like number of seeds per plant highest under the treatment spacing 120 x 45 x 45 cm and seed yield per plot was recorded in spacing 45 x 30 cm as well as cycocel 1000 ppm.
