The alpine and sub-alpine areas of North-West Himalayas provides a matchless wealth of highly priced medicinal, aromatic plants and are known as a natural reservoir of these herbs. In alpine pasture and meadows (bugyals) due to continuous loss of forest land, uncontrolled grazing and irregular exploitation of medicinal helrbs by commercial enterprises have resulted in depletion of valuable medicinal plants used since ancient times. There are many medicinal plants which have become rare in several tracts while a few others have fallen in the list of endangered species. Therefore it has been felt that there is an urgent need for conservation, ex-situ and in-situ cultivation of these valuable and threatened species by establishing high altitude nurseries in their natural habitat, so that regular supply to pharmaceutical industries and users could be maintained and above all this valuable flora of the alpine/sub-alpine areas of North-West Himalayas could be conserved.- Design and Cost Estimate of Mist Chambers for Vegetative Propagation of Forest Trees

Sand culture experiment was conducted on Teak (Tectona grandis) seedlings to study the mineral Nutrient requirements with respect to Nitrogen, Potassium and Phosphorus. Within the limitations of the experiment the results have indicated that for good growth, teak seedlings require about 680 mg/Plant of Nitrogen and Potassium and about 450 mg/Plant of Phosphorus. Results of the chemical analysis of the plant material have shown that higher application of Nitrogen and Phosphorus (680 mg/ Plant) increases the absorption of these minerals as well as of Calcium. and Magnesium by the plant tissues in comparison to lower (340 mg/Plant) application of Nitrogen and Phosphorus. As regards the application of Potassium the results have shown inverse correlation with respect to the absorption of Calcium. and .Magnesium by the plant tissues. Higher Potassium application (680 mg/Plant) has resulted in lower absorption of both Calcium and Magnesium. In respect of three element treatment combinations the data on ash percentage have indicated that higher Potassium application increases the ash percentage in the plant tissues.- Vegetative Propagation of Eucalyptus tereticornis Sm.
