SHOREA ROBUSTA GAERTN.F.(SAL) IN THE FORESTRY OF NEPAL

The distribution, silvicultural characteristic, growth rate and economic importance of S. robusta Gaertn.f., an indigenous hardwood species in Nepal, were analysed. The natural S. robusta forests in the southern plain of Nepal (the Bhabar-Terai) have been seriously degraded during the past decades. Forest inventories and trials in Nepal have revealed a good regeneration potential foe the existing S. robusta forests. ... Read More »

Growth, Biomass and Nutrient Content of Acacia Hybrid Clones in Sa Kaeo Province

Growth, biomass and nutrient of acacia hybrid clones planted in Sa Kaeo province was conducted by using randomized complete block design (RCBD) in 4 years old acacia hybrid clones. The spacing of tree planting was 3×3 m with 4 blocks. Each block consisted of 6 clones, i.e., 1, 3, 5, 14, 18 and 19. Each clone planted 24 trees. The ... Read More »

Effects of Different Spacing on Growth and Yield of Eucalypts Planted on Paddy Bunds

The effect of different spacing distances between trees on the growth and yield of eucalypts planted on paddy bunds was studied at two sites, Ban Nhong Nok-eiang and Ban Koh Khanoon, in Phanom Sarakham district, Chachoengsao province. Five different spacings: 0.5, 1.0, 1.5, 2.0 and 2.5 m were used in a randomized complete block design (RCBD) with three replications. Trees ... Read More »

Growth of Different Eucalypts Clones Planted on Paddy Bunds

Eucalypt clones planted on paddy bunds in Chachaengsao province were compared at two sites, Ban Huai Pleek, Phanom Sarakham district (21 rai) and Ban Nhong Kanai, Sanam Chai Khet district (29 rai). Both sites were cultivated with one crop of rain-fed rice annually. Four eucalypt clones (K51, K58, K59 and K7) from the Eucalyptus Technology Company (Eu-Tech) were planted using ... Read More »

Growth and Aboveground Biomass of Melaleuca cajuputi Powell in Noboru Umeda Tagum Plantation, Trat Province

The growth and aboveground biomass of 29-year-old Melaleuca cajuputi Powell planted in Noboru Umeda Tagum Plantation, Trat Province was studied in seasonal (7-9 months) and yearly flood areas.  In each area, three plots, (40 m x40 m size of each) were established by using a randomized complete block design.  The diameter at breast height (DBH) and total height (H) of ...
