Description An experiment entitled "EFFECT OF PLANT GROWTH REGULATORS
AND MICRONUTRIENTS ON GROWTH, FLOWERING AND YIELD OF
MARIGOLD (Tagetes erecta L.)" was conducted at the Botanical-cum-
Horticultural garden, College of Agriculture, Rajendranagar, Hyderabad,
during Kharif, 1987.
The effect of two growth regulators ( GA3 and CCC) and
one micronutrient. (Zn) each at two levels applied as root dipping
and foliar spray viz. GA
3
(50 and 100 ppm), CCC ( 500 and 1000 ppm)
and ZnS04 (0.2% and 0,4%) was studied on marigold. Thus there are
12 treatmental combinations along with one control. The experiment
was laid out in a randomized block design with three replications.
Observations on different growth and yield characters were recorded,
In general, all the chemical treatments differed significant!

the plant growth regulators applied GA

and resulted in the production of less number of laterals, thereby
less number of flowers per plant and finally less yields were recorded.
GA3 was found to be more effective at higher concentration
(100 ppm).
The growth retardant CCC.,. was effective in suppressing
the plant height and produced more number of laterals which ultimately
resulted in higher yields (by number and weight), CCC also
markedly increased the dry weights of plant and fresh and dry
weight of flowers. The most important contribution of application
of CCC is the advancement of flowering and increase in thickness
of flowers.
The application of Znso

produced was highest in Znso

treated plants and the accumulation
of Zn was also found to be maximum in ZnS0

treated plants.
Among the two methods of application, foliar application
was found to be more effective than root dipping.
Maximum net profits were obtained with the application
of GA3 at 100 ppm although the flower yields were maximum with
the foliar spray of CCC at 1000 ppm because of superior flower
quality.
