Abstract:
An investigation was carried out to study the “Effect of spacing and growth retardants on flowering quality 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 (Flat bed), 45 x 30 cm (Flat bed) 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, The flower quality parameters in terms of days to first harvesting from transplanting were found earlier in the treatment spacing 120 x 45 x 45 cm as well as control treatment. Whereas, highest flowering span and diameter of fully opened flower and weight of fully opened flower was found highest in spacing 120 x 45 x 45 cm as well as cycocel @1500 ppm. The maximum number of flower per plant was found in the treatment spacing 120 x 45 x 45 cm as well as cycocel 1000 ppm.
