Growth Parameters
Foliar application of GA3 and NAA significantly
enhanced vegetative growth of marigold (Table 1).
Application of GA3 proved better for plant height as
compared to NAA, whereas NAA showed better
result in respect to leaf area and chlorophyll content
in leaves as compared to GA3. The effect of GA3 and
NAA on number of primary branches per plant did
not differ significantly. Application of GA3 significantly
increased all the growth characters as its levels
and number of sprays increased. The plant height
and leaf area were recorded maximum at higher
