Evaluation of selected short rotation tree species for growth, biomass and carbon yield under south Gujarat condition
Research Type
Departmental Research
Experiment Background
hort-rotation forestry (SRF) play a vital role in the present scenario to meet out the industrial requirements of raw materials and SRF emphasizes the growth of high-density fast-growing tree species in plantations with the primary objective of producing high woody biomass. In SRF, fast-growing forest tree species are cultivated at a high density, with the aim of producing high biomass and growth within the shortest possible time span. The tree species grown in SRF may attain an exploitable diameter within 5-10 years depending upon the species, quality seed source, local environment and management practices over conventional timber yielding tree species. SRF aims to overcome the escalating industrial demands of commercially important wood species in the pulp, paper, furniture, and transportation sectors, among others, as quickly as possible. Important SRF species used in India includes Populus sp. Eucalyptus sp. Casuarina sp., Acacia mangium, Melia sp., Subabul, etc. which has been reported to give higher pulp yield; hence, important species for pulp and paper industries. Evaluation of different genotypes of few such species has has already been initiated by the College of Forestry, NAU, Navsari in different field trials. However, combined evaluation of such short rotation tree species in a common place is not available. Hence, the study is proposed to understand the eight short rotation tree species viz., Nilgiri, Saru, Malbar neem, Bangali baval, Mangium, Ardu, Kadamb and Killai, in block plantations for its growth, biomass and carbon yield comparison at NAU campus.
