Because of high demand in international and national market, crude drug supplies still collected from the wild sources and negligible efforts have been done in developing proper agro techniques. An attempt have been made to enhance growth and yield of the plant under different decapitation and spacing experiments. The results of the present investigation indicates that decapitation of Swertia chirayita greatly influence the growth and yield parameters. Decapitation of plants at 60 cm height resulted in maximum fresh aerial biomass/plant (65.34 g), dry aerial biomass/plant (23.16 g), fresh root biomass/plant (5.53 g), dry root biomass/plant (1.76 g), whole plant fresh biomass/plant (70.87 g) and whole plant dry biomass/plant (24.92 g). Among all the spacings, whole plant fresh biomass per plant (56.77g) and whole plant dry biomass per plant (19.98g) was recorded maximum under medium spacing of 30 x 45 cm.

It is used in different systems of medicine and exhibit anti-malarial, antidiabetic, antipyretic, hepatoprotective, antiinflammatory and anticancer etc., properties. Present study was conducted to investigate the effect of two treatments as 1) M1-with dry grass mulch and, 2) M2-without mulch under different line spacing levels viz.1) S1-10cm, 2) S2-15cm and 3) S3-20cm on germination % and seedling vigour of Andrographis paniculata. The results revealed that significant higher germination %, survival percentage, number of leaves per seedling, root & shoot length, fresh root & shoot weight/seedling, dry root and shoot weight/ seedling was observed at 10cm line spacing using mulch as compared to control. Thus application of mulch can be a best option for obtaining uniform and healthy seedling vigour in Andrographis paniculata.

The results revealed that transplanting time had significant effect on growth and yield of the species. The crop transplanted on 15 February gave maximum values for plant height (36.82 cm), herb yield (173.15 q/ha), oil content (0.24%) and oil yield (50.89 kg/ha) as compared to January and March transplanted crop. Among different spacings 30 x 45 cm spacing registered maximum plant height (38.26 cm), herbage yield (188.30 q/ha), oil content (0.25%) and oil yield (48.72 kg/ha). Use of NPK registered maximum plant height (43.39 cm), herb yield (271.96 q/ha), oil content (0.42%) and oil yield (81.38 kg/ha) followed by application of vermicompost, FYM and Azotobacter. Use of optimum dose of NPK gave maximum cost/...

Although propagated through seeds, there is always a scope for enhancement of seed germination capacity either through selection of accessions that have natural high seed germination rate or through some physiological interventions. We have examined the influence of hydropriming treatment on seed germination parameters that have revealed a positive correlation between hydropriming and higher germination rates.

Due to its high demand and scarcity, several other species of Swertia viz. Swertia alata, Swertia angustifolia, Swertia cordata, Swertia purpurascens and Swertia paniculata etc. are being used as substitutes /adulterants for Swertia chirayita in India, Japan, China, Pakistan and other Asian Countries. In order to check this adulteration and to assure genuineness of ‘true chirayita’, it is essential to know the detailed physico-chemical features of a drug plant. The present study was carried out on some Swertia species i.e., S. chirayita, S. alata, S. cordata, S. angustifolia and S. purpurascens for discriminating Swertia chirayita from its adulterants.Various ash and extractives values observed in this study may help in differentiating “Tru...

The bitterness in S. chirayita is due to presence of two secoiridoid glycosides amarogentin and amaroswerin. However, due to its high demand and scarcity, it is being frequently adulterated with other species of Swertia which are more readily available. Presently almost all the similar looking species of Swertia are marketed as ‘chirayita’ without any rationale which is affecting the potency of the drug. Present studies focused on evaluating Swertia chirayita along with its four common adulterants by developing TLC fingerprinting profile in petroleum ether, chloroform and methanol extracts employing amarogentin as a reference marker to distinguish genuine chirayita from its adulterants. The study revealed methanol soluble fraction of five Swertia species viz. Swertia chirayita, S. alata, S. ang...
