Abstract:
An investigation on “Effect of plant growth regulator on yield and quality parameters of calendula (Calendula officinalis L.)” was carried out by the Dept. of Floriculture and Landscape architecture, Pt. K.L.S. College of Horticulture and Research Station, Rajnandgaon during the year 2020-21. The purpose of research was to observe the effect of different concentrations of Gibberellic acid (200, 250, 300, 350 ppm), Naphthalic acetic acid (100, 200, 300, 400 ppm) and Salicylic acid (50, 100, 150, 200 ppm) in calendula plants yield attributes and quality attributes. The result revealed that maximum diameter of fully opened flower (5.43 cm), highest fresh weight (2.57 g), maximum flower yield per plant (99.78 g) and Maximum flower yield per plot (1596.48 g) were noted under SA @ 100 ppm. In research, control was reported minimum for every trait from different concentrated PGR taken in the investigation.
