Abstract :

A comparative study in rice planting between transplanting method using a 4WD 6 rows Ride-on KUBOTA NSPU68C 12.5W @3600 rpm transplanter and broadcasting method using a knapsack HARRY Mist Duster Power Broadcaster 2.13Kw @ 7500 rpm was conducted in a 9 hectares rice plot at Sungai Burung, Tanjung Karang, Selangor. Rice seedlings were planted using transplanter at a spacing of 20 cm×30 cm with 6 seedlings per hill while rice seeds were broadcasted by the Mist Duster at a seeding rate of 134.45 kg/ha or about 449 seeds/m2. The broadcaster showed 1.7 times greater mean effective field capacity (1.31 ha/hr and 0.49 ha/hr) and 7.38 times lesser mean fuel consumption (0.79 l/ha and 6.7 l/ha) than the transplanter. However, the fields under transplanting method showed 25.18% greater mean planting density (522 and 417 stems/m2), 20% greater mean number of panicles (480 and 400 panicles/m2), 7.3% less mean population of weedy rice (4.89% and 12.16% of weedy rice) than the field under broadcasted method. The mean spikelet filling percentage was found 83.2% for the fields under transplanting method and 77.8% for the fields under broadcasted method. The mean rice yield was 22.41% more with the fields under transplanting method than the broadcasted method (7.09 and 5.8 ton/ha). Transplanted method showed 1.71 times greater mean total economic cost of planting operation (1154.4 RM/ha and 426 RM/ha) but 1.8 times mean greater net income (1554.54 RM/ha and 555.76 RM/ha) than the broadcasted method. Benefit Cost Ratio of transplanted and broadcasted method was found to be 1.232 and 1.108.
