12% shallow rainfed (0-50 cm), and 4% intermediate rainfed (50-100 cm) (Table 3) (Huke and Huke 1990). Multiple cropping systems In Cambodia and Lao PDR, very little area is planted to a second rice crop, therefore, cropping intensity is very low. It is not known how much of the rainfed lowland rice area is planted to secondary crops after rice. Under upland conditions, land is usually left fallow after a single rice crop. However, limited cropping of mungbean and soybean has been observed in Cambodia (Nesbitt, 1991, pers. commun. ). In northern Vietnam the dominant cropping pattern is spring-summer rice. In the Mekong River Delta, rice is produced during three major cropping seasons: Dong Xuan (winter-s ring), He Thu (summer-autumn or midseason), and Mua (wet season; long duration 7 . Other crops have high potential in Indochina: sugarcane, coconut, sugar palm, pineapple, banana, orange, and other fruit crops. In addition, niungbean, sweet potato, soybean, and groundnut are important crops. FARMING SYSTEMS RESEARCH Integrated farming traditions are thousands of years old in Indochina, but are not fully reflected in production or in institutional support to agricultural production. Increased production of rice and increased productivity of rice-based farming systems, remain primary goals of the national plans in Cambodia, Lao PDR, and Vietnam. Crop selection has been guided by national policies and plans that stress rice production. Consequently, crop diversification has not occurred to any significant extent. During the past three decades, the development of farming systems research has mainly occurred in Vietnam, which is the focus of this section. Achievements There have been various programs and projects to support development plans and strategies in farming systems research. In the Red River Delta, where rice is the dominant crop, short season varieties were introduced to enable farmers to grow a third crop (e.g., sweet potato, potato, or vegetables). A system of raising livestock (garden + fish pond + animal house) has been introduced under the household system. Rural industries and handicrafts have been emphasized for nonagricultural laborers, but difficulties were encountered because of lack of materials and marketing.
In the midwest plain, where there are problem soils, zero tillage, raising soybean between rice, integration of rice and shrimp, raised beds for growing sandal trees, and raising shrimp in the canals have been studied. In the upland areas, where environmental degradation is a major problem, coffee trees have been planted across the slopes and green manure crops or legumes planted between the rows for the first three years. Different systems of land preparation have been tested for growing upland rice. Forest and abandoned lands were given to farmers. Studies in the Mekong River Delta focused on various rice-based farming systems models. Some of the models (e.g., rice-shrimp in fresh water, rice-shrimp in saline area, rice-fish in deepwater area, rice-fish integrated with fruit trees and beef cattle or dairy cattle, and rice-cash crops in floating rice areas) were initially developed by advanced farmers in the region. Technology transfer The transfer of technology was done mainly through demonstration plots. Researchers worked extensively with farmers to establish pilot farms in different ecological zones. Institutions The general level of interest in farming systems among scientists and planners in Vietnam is high. FSR in Vietnam is carried out by different agencies such as the National Institute of Agricultural Sciences (NIAS), the National Institute of Agricultural Planning and Projections (NIAPP), the National Institute of Agricultural Economic Research (NAER), the Mekong Delta Farming Systems Research and Development Centre of the University of Cantho, and various universities. Vietnam is also an active participant in the regional project Farming Systems Development in Asia: Crop/Livestock/Fish Integration in Rainfed Areas. However, there was a feeling that there was fragmentation in the support to agriculture at the separate research centers. This led to a project proposal for coordinated farn~ing systems research and evaluation in Vietnam. Use of resource maps FARMING APPROACH General land-use maps have been extensively used in Vietnam for physical planning. The crops most suited to the given physical conditions (e.g., climate, soil, and irrigation regime) are chosen with no account of the relative economic value of various crops.
