ジャーナル フリーThe accelerated economic growth of Thailand since the late 1980s has made the urban-rural relationship more direct in terms of people's mobility and the circulation of information and money, and this is transforming landuse and agriculture. A typical example of this transformation is the change in the planting method of lowland rice in Northeast Thailand, which the present study highlights. Two years' field observation of 178 plots and interviews with 100 farmers in the Chi and Mun river basins demonstrated a drastic change in the planting method from transplanting to dry seeding as a result of trial and error by farmers. Northeastern farmers tend to attach greater importance to minimizing labor input to rice cultivation than to maximizing rice production. This change reflects the structural changes in the region: the rise to prevalence of the money-based economy and the disappearance of the rice-based economy.抄録全体を表示PDF形式でダウンロード (1542K) -

ジャーナル フリーIn Northeast Thailand, the planting of nonglutinous rice for sale is now spreading to some villages where only glutinous rice was traditionally grown. In these villages, rice productivity has increased, due mainly to the introduction of chemical fertilizer which normally accompanied the change in the type of rice planted, rather than the higher productivity of the nonglutinous varieties. Though fertilizer application, glutinous rice production has also become sufficient for domestic consumption and a surplus has appeared. The commercialization of rice-growing was made possible by higher productivity of more than 400 kg per capita annually, and lower annual fluctuation of yields. Productivity was effectively raised by fertilizer application to all paddy fields in a village located in a area of high rainfall far from a floodplain, which escaped the effects both of severe drought due to an unreliable dry spell and of flooding. Here, the higher price of nonglutinous rice, expanding demand for cash in village life and the paucity of agricultural products other than rice promoted the villagers to plant nonglutinous rice.抄録全体を表示PDF形式でダウンロード (1742K) -

ジャーナル フリーTo examine whether the prevailing rice farming in Northeast Thailand is sustainable in terms of agro-ecology, the gain and loss of plant nutrients between a paddy plot and its surroundings were studied in the village of Um Mao, Roi Et Province from 1993. The loss of major nutrients, including N, P and K, from the paddies in the form of harvested grains was well balanced by the gain from chemical fertilizers. It was judged that the present farming is fairly compatible with the environment at the current yield level of around 2 ton of unhusked grain per ha. Higher than the present dose of fertilizer would probably result in lower efficiency of application and little increase in the yield. Farmers appear to be well aware of this. For further improvement of the productivity, other means should be sought.抄録全体を表示PDF形式でダウンロード (860K) -

ジャーナル フリーRice and rubber were major farm products for export from Thailand before the 1950s. Maize and other field crops were added to them in the 1960s. They were cultivated in newly opened lands. This paper describes the process of reclamation and the changes thereafter in a typical area of commercial cultivation of maize, and analyzes the land, technological and economic factors related to them.
The fieldwork was carried out in an area extending between Saraburi and Lopburi provinces, which was reclaimed in the 1950s. Within the area, significant variations in cropping pattern, technology and productivity were observed. These spatial variations were largely governed by such physical conditions as rainfall and soil until around 1980. Thereafter, various modern technologies were adopted within a short period, which resulted in greater diversification in crops and the farming system.抄録全体を表示PDF形式でダウンロード (1362K) -
