| Abstract | Agriculture is one of the most important sectors of the economy of the Lao PDR. It contributes to 51% of the GDP and employs 86% of the total labor force. Among agricultural sub-sectors, rice production is the single most important activity and is undertaken primarily by smallholder producers. At present situation in Lao as many countries, there are some yield gaps between rice farmers and research stations. The potential yields of rice production in the experimental station usually higher than the farmer levels. To providing necessary possible ability to increasing the rice yield in Laos. This study was conducted to find out the potential rice yield constraints in the study area by using fanner survey in comparison between the farming without extension support and with extension service support. Introduction of some remedies were done in order to minimize the yield gap among the farmers who are in ParkNgum district vietiane capital, Lao PDR. Framer survey was conducted to investigate the existing constraints, major management drawbacks. In addition, the potential yield from experimental station and LAO-IRRI were compared with actual yield of fanner survey. The potential yield gap and actual farm yield was identified. Both farm categories have 100% land use intensity in their own lands. Whatever both farming types differences in getting support from extension services, the average yield of both farming types were not much difference of 3.1 /ha and 3.0t/ha respectively. This may exposed poor extension support did not help to increase farmers' yield potential. It still less than the IRRI research stations existing yield reported 4.5t/ha than other rice field. The cultural practices and management in terms of irrigation management, control of nutrient deficiency, pest and diseases, application of fertilizer, were management, seed variety, and seed rate used, etc. were the main reasons behind for these yield differences. The results also revealed that the major constraints as financial problem, pest and disease problem, lack of government subsidies and higher price of inputs form farmers selfreporting. According to that the miner constraints are middle man problem, Infrastructure facility, storing problems, seed varieties and quality, and lack of irrigation facility. Government intervention, launching some farmer awareness programes through extension services, and site specific fertilizer recommendation, are key factors to overcome existing problems associated with paddy cultivation in Lao PDR. |
