  From many perspectives, agricultural production is essential to the economic growth of the least developed countries (LDCs). While international trade is considered one of the main sources of growth, the fact that LDCs rely heavily on primary commodities export and may not benefit significantly from trade raises concerns about the impact of trade on the economic development of LDCs. In this paper, the instrumental variable method was employed to ensure consistency and unbiasedness of the estimates of the impact of trade on agricultural productivity. The resource rents was used as an instrumental variable in determining the export and import indexes, especially in the case of LDCs. The semi-elasticity showed that a one percentage point increase in the terms of trade reduced agricultural productivity growth by approximately 0.23% on average, holding other factors constant. This estimate was statistically significant, and implied that expansion in trade does not improve agricultural productivity in LDCs.

  The use of irrigation mat made from textile materials is a new research trend for hi-tech agriculture. This technology has been using in developed countries such as Germany and the Netherlands. This paper summarized the study results on the effects of irrigation mat KT2 and three types of substrates on the watering cycle, the required amount of water, the growth and quality of dwarf marigold. The study composed of three experiments. The experiments were conducted with six treatments using the random complete block (RCB) design in the nethouse from January to June 2011. The experimental results indicated the following advantages of using irrigation mats: limitation of water loss, an appropriate water amount based on the demand of plant, long moisture retention of the substrates, extended watering cycle, and reduced water requirement and labor as compared with control treatment (no irrigation mats). Growing the plants using the substrate No.3 (alluvial soil, cattle manure, sooked rice husk and coconut fiber with the ratio 1.5:1:1:0.5) in combination with irrigation mat and normal irrigation methods gave better results than the substrate number 1 (alluvial soil) and 2 (alluvial soil, cattle manure and burning rice husk with the ratio 3:1:1).

  Agritourism is a popular type of tourism in developed countries, but it has been only paid attention to by developing countries including Vietnam recently. Developing agritourism brings much benefits such as diversification of agricultural activities, economic growth, preservation of cultural identity, production, and reduction of environmental pollution, but remains some limitations. This paper presents the results of the overall analysis of experiences in developing agritourism in the world, opportunities, and challenges for agritourism development in Vietnam. From there, some suggestions on the policy for agritourism development of Vietnam in the coming time are proposed.
