Abstract
Gerbera is an commercial flower crop produces very attractive flowers in various colours and ranked among the top ten cut flowers. It is also called Transvaal daisy, Barberton daisy or African daisy besides as a cut flower it is also very ideal for beds, borders pots. Growth regulators are used to overcome the factors limiting the growth and yield to harness maximum benefit. It is also observed that foliar application of growth regulators stimulates flowering to get maximum yield. In gerbera it stimulates cellular elongations, so without them, cells do not elongate much and plants do not grow tall. In this experiment, an attempt was made to find out the effect of certain new generation chemicals along with plant growth promoters (GA3 and Triacontanol), growth retardants (Maleic hydrazide, Alar), new generation stimulants (Campesterol +Stigmasterol) and organic supplements (Sea weed extract) on growth and yield of Gerbera. Humic acid was added to all the treatments as growth booster. The growth regulators were applied as foliar spray at 30 days after transplanting and continued at 30 days interval. Observations on various growth characters viz., plant spread, number of leaves, leaf length, leaf width, leaf area, flowering parameters viz., days to first flower emergence, number of flowers, flower diameter, stalk length, stalk diameter were recorded. From the experiment, it was concluded that, foliar application of GA3 @ 300 ppm along with Humic acid @ 2000 ppm was found to increase the growth and flower yield of Gerbera under poly house conditions
