IFDC Report, Volume 10, No. 3
This report discusses the development of a USG (urea supergranules) dispenser with a transplanting guide for hand-deep placement of urea fertilizer during rice transplanting. The goal of this research by the International Fertilizer Development Center (IFDC) is to provide affordable technology applicable to developing countries. Deep placement of USG has been proven efficient in increasing rice yields and reducing nitrogen requirements. The report describes the design and operation of the dispenser, highlighting its simplicity, affordability, and effectiveness. Preliminary trials conducted in India show a significant reduction in labour required for deep placement and potential benefits such as protection of USG from rain and floodwater and minimal disturbance to the transplanted seedlings. The report also emphasizes the need for affordable briquettes to produce USG as a complementary technology. Further trials and demonstrations will transfer this technology to small-scale rice farmers. The report highlights the potential impact on rice production in developing countries.
