Abstract

The experiment carried out to study growth, flowering and yield parameters of Narcissus by using growth regulators, i.e., benzyladenine and gibberellic acid in different concentrations, revealed that application of BA (400 ppm) significantly increased length of leaf, width of leaf, width of scape, plant height, early opening of 1st flower and increased number of roots plant–1. BA at 300 ppm resulted in late senescence of 1st flower and diameter of bulb. Lower dose of BA i.e., 100 ppm significantly increased number of buds plant–1 and number of open flowers plant–1. Higher concentration of GA3 (200 ppm), significantly delayed opening of last floret, increased duration of flowering, number of bulbs hill–1, diameter of root, fresh and dry weight of roots. However, lower dose of GA3 (50 ppm) exhibited maximum weight of bulb and length of root.
