Improved Design of Urea Supper Granule Applicator
Authors: Shamim Ahamed, M., A. M. Ziauddin, R. Islam Sarkar
Description: The application Urea Supper Granule (USG) in the paddy filed is an innovative technology to reduce the nitrogen fertilizer losses from the field. Scientists from Bangladesh Agricultural Research Institute (BARI) have developed a manually operated two-row USG applicator. The applicator perform well to place the USG at a particular depth of soil in the center of the four rice bounces. However, the applicator have some problems including the missing of USG placement, placing more than one, high self-weight and breaking of USG because of friction with the moving parts of the applicator. The several components of the applicator were modified including the wheel, skid, hopper, metering disk, discharge tube, and handle of the applicator. The filed test results indicated that the improved version of the applicator perform well than the original version. The field capacity of the newly designed applicator was 10 times higher than the BARI model for two available size of the USG. The missing rate, multiple application, breakage & dust formation were also reduced about 9%, 5%, and 5%, respectively.
