Abstract:
A field experiment was carried out to investigate the efficacy of different plant growth regulators and their combination of gibberellic acid (GA), Naphthalene Acetic Acid (NAA), Kinetin, Miraculan, their combinations and their mode of application on morpho-physiological traits and growth parameters of patchouli during 2014-2015 at research cum instructional farm of Indira Gandhi Krishi Vishwa Vidyalaya, Raipur (C.G.). Plants were sprayed two times 60 and 75 days after planting. The experiment was carried out in a randomized block design (RBD) with eight treatments and three replications The results revealed that foliar application of PGRs significantly enhanced the morpho-physiological traits i.e. Plant height, number of branches, number of leaves, leaf area, leaf area index, SLA and SLW of patchouli compared with control. Plant growth regulators are efficiency including morphological characters and photosynthetic ability which depends on the chlorophyll content of plant and offer significant role in realizing higher crop yields and higher oil content which is specially collected in the leaf of patchouli.
