Responses of Iba and Naa on Shoot and Root Growth of Semi Hard Wood Cuttings of Guggul [Commiphora Wightii (Arn.) Bhan.]

Abstract

The need of today world is high output yield and enhanced production of the crop as well as incorporates new technologies i.e. application of plant growth regulators (PGR). Poor seed set and germination limits propagation of Commiphora wightii plant. To fulfill the supply-demand gap, it is essential to develop propagation and agro technique for the Commiphora species. The PGR usually affects the physiological processes of growth and development in plants, when applied in low concentration. Hence, the present study was carried out to standardize the techniques for mass multiplication at Department of Plantation, Spices, Medicinal and Aromatic Crops, College of Horticulture, RVSKVV, Mandsaur (M.P.) during the year of 2021-22. The experimental material was consisting of eight combinations of PGRs (IBA and NAA@ 250, 500, 750 and 1000 ppm both) with one untreated control were used in CRD Design with three replications. Treatment T 3 -IBA 750 ppm had early sprouting, maximum sprouting, chlorophyll content, number of leaves, leaf area, leaf weight at 120 days after planting (DAP). The maximum leaf area index was recorded in treatment T 3 -IBA 750 PPM at 90-120 DAP. Among shoot parameters, treatment T 3 -IBA 750 ppm was registered the highest number of shoots, longest shoot, fresh weight of stem and dry weight of stem at 120 DAP. Among root parameters, treatment, T 3 -IBA 750 ppm was recorded early rooting, maximum rooting and survival, more number of roots, longest root, fresh weight of roots and dry weight of roots at 120 DAP. The maximum gross income, net income and B:C ratio per treatment was recorded with T 3 IBA 750 ppm i.e., Rs. 18, Rs. 15, respectively.
