    Urea deep placement (UDP) technology has been introduced to Myanmar by the International Fertilizer Development Center (IFDC) as a science-based technology that can increase nitrogen use efficiency by 40%, allowing less urea to be applied to produce higher yields. Farmers can save money, maintain soil fertility of their lands, and can get higher yields. Through the Fertilizer Sector Improvement (FSI) project, IFDC implemented UDP adaptation trials in the 2014 wet season in Yangon, Bago, and Ayeyarwady regions. Extension activities started among farmer communities in the 2015 dry season through a program of "Balanced Nutrient Management and Urea Deep Placement Technology." This included farmer trainings with field demonstrations that publicized the benefits of the new technology. Demonstration plots were established during the 2015 dry season to 2016 wet season with three treatments: (1) UDP on transplanted rice; (2) UDP on broadcast- seeded rice; and (3) farmers' practice of planting and fertilizing. The layout of the demonstration was simple, without replication, but there were at least 30 demonstration plots established in each season. According to the results from four seasons, UDP on transplanted rice was the best nitrogen application practice, followed by UDP on broadcast-seeded rice. The FSI project also took crop cuts from a random sample of farmers' fields who apply UDP in each season. UDP plots produced between 750-1,000 kilograms per hectare (15-20 baskets/acre) more yield than non-UDP plots. These results showed farmers that UDP technology can reduce cost of urea and increase income.
