| Abstract | More than ten years of experimentation have demonstrated that the use of Urea Deep Placement (UDP) results in significantly higher N Use Efficiency (NUE) than broadcasted prilled urea (PU) for lowland rice in Bangladesh. UDP use increases yields, reduces quantities of urea applied, increases farmers’ returns, and produces national savings due to the reduction of urea imports. Ongoing research indicates that large-scale adoption of UDP also has environmental benefits due to reduced N losses and greenhouse gas emissions. The objectives of this research were to estimate UDP adoptions, compare PU and UDP concerning yield, assess methods used for the diffusion of UDP technology, and identify factors with the potential to constrain UDP adoption. Two-cluster sampling was used. Results show that UDP has been widely adopted across the seasons, albeit to differing degrees. Additionally, diffusion strategies such as farmer training and field demonstrations have proven to be effective in improving yield and NUE compared to PU. However, obstacles like the need for hand application and the scarcity of briquettes prevent wider implementation. Using mechanized techniques, recommendations include extending the UDP application to more fields and enhancing briquette dispersion. | |
