| Abstract | The field performance tests were performed on the 12-row comb-type Chinese rice transplanter by having 3 variations of ages of seedlings (22, 28 and 34 days, variety RD-11), 3 variations of depths of water (0-1, 2-4 and 5-7 cm), 2 variations of throttle settings (half and full throttle) and 2 variations in soil conditions (soft soil condition:
1 plowing and 2 puddling and levelling about 3-5 days before transplanting; standard soil condition:- 1 plowing and 1 puddling and levelling about
7-10 days before transplanting). The results and analysis showed that 28 days old seedlings with depth of water upto 1 cm and 34 days old seedlings with depths of water upto 7 cm, ·would give better performance while working in standard soil condition and full throttle settings. The picking performance at these combinations were averaged as; non-productive hills - 12.76%, hills containing 1-4 seedlings - 76.13%, average number of
seedlings per hill - 2.73 and total number of seedlings per 10 square meter - 816. The field capacity of the transplanter was measured to be 0.072 ha/hr with 28 days old seedlings, 2-4 cm deep water, full throttle and
standard soil condition in a field 55 m x 29 m. Possible modifications were recommended to improve performance. |
