Abstract

Albizia falcataria (L.) Forberg is one of the most fast growing species. It makes few demands on the soil and hence is suitable for rapid afforestation of poor soil. On account of its wide adaptability, the species promises to be one of the excellent planting materials for social forestry and wasteland afforestation programmes, particularly in areas where the rainfall is good. The paper deals with the results of an experiment, carried out on its nursery technique and choice of better provenance under Dehra Dun conditions.

Abstract

Eucalypts introduction trial at New Forest, which include 24 entries, is reviewed. The species are Eucalyptus astringens, bicostata, botryoides, camaldulensis, citriodora, dairympleana, diversicolor, ficifolia, grandis, 'hybrid', leucoxylon, longifolia, maculata, melanophloia, polybractea, populnea, robusta, rudis, sideroxylon, staigeriana,. tereticornis and 12 ABL. Based on their performance, species have been broadly categorised into three groups namely promising, average and failure, Varied performance of the species is attributed to comparability of locality factors of the donor and the recipient region i.e. Dehra Dun. Important factors contributing to success or failure are identified as comparability on the parameters of latitude, elevation, soil and climatic conditions particularly the temperature regime,frost and rainfall type. Among the species evaluated Eucalyptus tereticornis, melanophloia, saligna, longifolia, camaldulensis, dairyrmpleana, populifolia and robusta are indicated as promising species for the sub Himalayan zone.

Abstract

Acacia albida Del. is a multipurpose Sahelian Zone African tree. This tree is extensively used in Agro-foretry purpose. This species is belong introduced in Indian conditions. An investigation was taken up in tbe Nursery of Silviculture Branch of Forest Research Institute, Dehra Dun, to standardize its nursery tecbniques. For finding out the best combination of soil media and containers. The findings of this experiments are discussed in this paper.
