Financial Return from Eucalypts Planted on Paddy Bunds

This research was carried out in Chachoengsao province and aimed to compare the financial return from three land uses: paddy field (PF), single-row planting of eucalypts (75 trees/rai) on a paddy bunds (OEP) and two-row planting of eucalypts (150 trees/rai) on a paddy bunds (TEP). The sample households who had planted the three crops were interviewed. Eucalypt trees from the ... Read More »

Leaf Gas Exchange Characteristics of Four Eucalypt Clones Planted on Paddy Bunds in Chachoengsao Province

Leaf gas exchange characteristics play an important role in tree growth and carbon storage. In this study, the leaf gas exchange characteristics of four eucalypt clones planted on paddy bunds were investigated in two on-farm study sites in Chachoengsao province. Specifically, four leaf gas exchange characteristics were measured in the wet and dry seasons: light-saturated net photosynthesis, stomatal conductance, transpiration ... Read More »

Carbon Storage of Eucalypts Planted on Paddy Bunds in Chachoengsao Province

This study investigated the potential to store carbon in the biomass of eucalypt clones planted on paddy bunds in two trials in Chachoengsao province: 1) a clonal trial of four clones; and 2) a spacing trial with five different distances between trees. There were two study sites on farms in each trial. Three years after planting, samples of stems, branches, ... Read More »

Effect of Spacing on Soil Properties of Eucalypts Planted on Paddy Bund in Chachoengsao Province

The effect of spacing on the soil properties of eucalypts planted on a paddy bund in Chachoengsao province was investigated at a spacing trial in Phanom Sarakham district. The trial plots were established using a complete randomized block design (CRBD). Trees from clone K51 were planted in a single row with spacing between trees of 0.5, 1.0, 1.5, 2.0 and ...

Root Distribution of Eucalypts Planted on Paddy Bunds in Chachoengsao Province

The root distribution of eucalypts planted in Sanam Chai Khet district, Chachoengsao province was investigated at a clonal test site planted on a paddy bund. Eucalypt clones K7, K51, K58 and K59 were planted in a single row with 1 m spacing between trees. Trees sampled were aged 1.5 years and 3.5 years. Three average trees in each age class ...

Water Use and Water Use Efficiency of Eucalypt Clones Planted on Paddy Bunds in Phanom Sarakham District, Chachoengsao Province

A study on water use and water use efficiency of trees from the K7, K51 and K58 eucalypt clones planted on paddy bunds was carried out at Phanom Sarakham district, Chachoengsao province. Diameter at breast height (DBH), total height (H) and water use were determined at two-monthly intervals, over the period when the trees were one to three years old. ... Read More »

Planting Eucalypts on Modified Paddy Bunds during the Dry Season with Intensive Care and Fertilization

This research considered the possibility and potential of planting eucalypts on modified paddy bunds during the dry season using intensive care and fertilizer application. The average survival rate of eucalypts planted in each month during the dry season was about 94.75%, which was rather better than the survival achieved in occupational plantings by farmers in the areas. The average growth ... Read More »

Planting Eucalypts on Paddy Bunds, Along Fence Lines and in Front Backyards

Applied research was carried out on the possibility and potential of planting eucalypts on paddy bunds, along fence lines and in front backyards to earn additional income for farmers. The study was carried out in 22 districts in Chachoengsao and Prachinburi provinces, with 660 farmers participating. A total of 84,700 eucalypt cuttings from the Cooperative Eu-Tech Co., Ltd were used. ... 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 »
