Abstract/ Executive Summary:

Among the planted 19 threatened forest tree species at four research stations, the maximum survival and height were found in chikrassi and dharmara (68.0%) and 104.5cm in chikrassi at Keochia, 77.0% in teligarjan and 138.0cm in kannayri at Charaljani, 50.0% in box badam and pitraj and 51.8 cm in box badam at Charkai and 65.0% in royna and 100.0 cm bolaj at Lawachara. The height and diameter of culm of 07 years age of muli bamboo planted through seeds was found higher at Charaljani (5.0-9.0 m and 5.0 -17.0 cm) than Charkai (2.7 m and 2.0-2.7 m). The total number of culm and mature culm was also higher at Charaljani (45–80 and 1-16) than Charkai (6-22 and 1-15).

Keywords: Growth performance, Agro-ecological regions, Silvics, Quality seed sources.

Start Date: 00-00-2012

End Date: 00-00-2015

Program Area: Resource Development and Management

Non-commodity: Performance

Objectives:

To assess the growth performance of different tree species in four agro-ecological regions of the country.
To determine the silvics of different forest tree species.
To develop future quality seed sources.

Methodology:

The study was conducted at Keochia, Lawachara, Charaljani and Charkai Research Stations. During the study period, maintained 80.0 ha previously raised experimental plantations (ex-situ conservation plots, species elimination and site suitability trial, provenance trial, mixed species trial plantations, bamboo plantations, etc.) by weeding at different Research Stations. Silvicultural techniques i.e., spacing, weeding, fertilization, pruning, thinning and coppicing for plantation management were followed to develop for maximizing yield of the plantation.
