There are a large number of herbal gardens in India and most of them are not linked and classified the availability of medicinal plant species of these gardens. In this study, the hierarchical clustering technique of data mining was applied on the herbal gardens of India and classified in order to discover meaningful patterns such as what type of habit of medicinal plant species is present in which location of India. © 2005 - 2011 JATIT & LLS.

An investigation was conducted to find out the effect of different organic manures on growth, yield and quality of makoi (Solonum nigrum L.). The experiment comprised of 13 treatments consisting of different combinations of organic manures (FYM @ 10, 15 and 20 t, vermicompost @ 0.5 and 1.0 t and neem cake @ 0.5 and 1.0 t ha -1 ) and FYM 10 t + NPK @ 100:50:50 kg ha -1 through inorganic fertilizers. Maximum plant height, number of branches per plant, plant spread, number of leaves per plant, leaf area and total dry matter accumulation were recorded with the application of FYM 20 t + vermicompost 1.0 t + neem cake 1.0 t ha -1. Fresh and dry herbage yield were also maximum with the same treatment. However, application of FYM 20 t + vermicompost 1.0 t + neem cake 0.5 t ha -1 resulted in maximum alkaloid content and alkaloid yield, whereas, the highest net returns of Rs. 34,000 ha -1 and benefit to cost (B:C) ratio of 1.80 was recorded with the application of FYM 20 t + vermicompost 1.0 t + neem cake 1.0 t ha -1.

Chlorophytum arundinaceum is an important medicinal plant and its tuberous roots are used for various health ailment treatments. It has become an endangered species in the Eastern Ghats, and a rare medicinal herb in India, due to its excessive collection from its natural habitat and its destructive harvesting techniques, coupled with poor seed germination and low vegetative multiplication ratio. In order to contribute to its production systems, an efficient protocol was developed for in vitro clonal propagation through shoot bud culture. For this, multiple shoots were induced from shoot bud explants on Murashige and Skoog's medium supplemented with 2.5-3.0mg/L BAP, 0.01-0.1mg/L NAA and 3% (w/v) sucrose. Inclusion of Adenine Sulphate (25mg/L) in the culture medium improved the frequency of multiple shoot production and recovered the chlorotic symptoms of the leaves. Media having pH 5.9 and 4% sucrose showed significant improvement on shoot bud multiplication and growth. In vitro flowering was observed when the subcultures were carried out for over four months in the same multiplication media. Rooting was readily achieved upon transferring the shoots on to half- strength MS medium supplemented with 0.1mg/L IBA and 2% (w/v) sucrose. Micropropagated plantlets were hardened in the green house, successfully established, and flowered in the field. This method could effectively be applied for the conservation and clonal propagation to meet the demand of planting materials. Source

Efficient plant regeneration in Aloe barbadensis Mill. was achieved using callus derived from shoot meristem. Organogenesis was maximum on MS medium supplemented with 2.5 mg/I BA, 0.25 mg/I IAA. Though sucrose (2%) showed maximum shoot bud regeneration capacity, D-glucose had an intermediatory effect, however, fructose and maltose had no effect at all. Of the conditions tested shoot bud regeneration was highest (82.8) under 12 h illumination. The regenerative potential was stable up to 12 sub-cultures. The rate of shoot bud regeneration was dependent on the concentration of hormones in the nutrient media. Regenerated shoots rooted on half-strength MS medium containing 0.1 mg/l IAA and 1% sucrose. The in vitro derived plantlets were hardened in the nethouse with 75% light and successfully established in soil. Source

An experiment was conducted to work out the optimum spacing for obtaining maximum biomass, essential oil and artemisinin yields in antimalarial herb (Artemisia annua L.) in the semi-arid region of Gujarat. It was laid out in a randomized block design with 5 spacing treatments, viz. 30 cm × 45 cm, 30 cm × 60 cm, 45 cm × 45 cm, 45 cm × 60 cm and 60 cm × 60 cm. There were no significant differences in growth parameters like plant height and number of branches among different spacings. However, significant differences were observed in yield characteristics and was found that the mean fresh (30.79 t/ha) and dry (18.35 t/ha) herb yield and fresh (7.7 t/ha) and dry (3.91 t/ ha) leaf yields, were maximum under spacing of 45cm × 45 cm. The leaf harvest index and leaf: stem ratio were also significantly higher under optimum spacing of 45 cm × 45 cm. No significant differences were observed in essential oil content, their composition and artemisinin contents among the different spacing but the yields of essential oil (54.95 kg/ha) and artemisinin (8.88 kg/ha) were found maximum in the spacing of 45 cm × 45 cm. © 2014, Indian Journal of Agronomy.
