 ABSTRACT

The present experiment was conducted to determine “Effect of Plant Growth Regulators on Growth and Flower Yield of Calendula (Calendula officinalis L.) cv.Calypso” under Allahabad agro-climatic conditions in the Department of Horticulture, Sam Higginbottom University of Agriculture Technology and Science, Allahabad, (U.P.) during the year 2017-2017. The laboratory experiment was conducted in Completely Randomized Design with three replications and used different plant growth regulators [(GA3 @ 100 ppm, @ 200 ppm, @ 300 ppm), (NAA@ 50 ppm, @ 100 ppm, @ 150 ppm, @ 200 ppm) and (cycocel@250ppm, @500 ppm, @750 ppm, @1000 ppm)], with 12 different treatments. The result reveals that T3-GA3 @ 300 ppm was effective in improving pre and post harvest parameters of calendula. Treatments influenced significantly plant height (cm), Plant spread (cm), Number of primary branches per plant, Number of leaves. The data revealed that significantly influenced the different post-harvest attributes in phalsa viz., Diameter of flower Weight of flowers, Flower yield per plant, No of flower per plant, Yield of flowers per plot and Shelf life of flower. Similarly, maximum T3-GA3 @ 300 ppm and minimum was recorded with T0-control.

Key words: Calendula, Plant Growth Regulators (GA3, NAA and cycocel)
