| Resumo: |
In this study the performance of a motorized palm fruit bunch harvester (MBH) was evaluated in comparison with the bamboo-pole-and-knife harvester (BPK). The MBH was first tested on Nigerian plantations for the palm trees it could reach. The average time taken to harvest a bunch and the time taken per hectare of plantation were determined. The best orientation and the cutting angle for the harvester were also determined. The exact height which the harvester could reach was also determined on the plantations. The harvester was later used in comparison with (BPK) method on palms of moderate height and the average time of harvest per bunch, field capacity, as well as cost of operation was determined for the two methods. Time study (TS) of the two methods was also carried out.The result showed that MBH could harvest between the height of 2.5 m and 4.5 m of palm conveniently. The average time of harvest per tree and speed of harvest for MBH and BPK were 98.86 s and 66 bunches/h; and 166.93 s and 40 bunches/h, respectively. This shows that time of harvest for motorized harvester is over 60% lower, and the speed of harvest is over 50% higher than bamboo pole and knife. The time of harvest per hectare for both MBH and BPK are approximately 4 h/ha and 7 h/ha, respectively. The rate of fuel consumption was estimated to be 1.03 L/h. Moreover, the cost of operation for MBH and BPK was estimated to be ₦ 10,223.46 and ₦ 16,950 per hectare, respectively. The cost of operation using the BPK is over 60 per cent more than that of the MBH. Statistical analysis of the effect of time of harvest on methods indicated that the effect was significant (p < 0.05). The study concluded that motorized oil palm bunch cutter can effectively and efficiently handle palms of moderate height in Nigerian oil palm plantations and performed better than the bamboo pole and knife. The result showed that MBH could harvest between the height of 2.5 m and 4.5 m of palm conveniently. The average time of harvest per tree and speed of harvest for MBH and BPK were 98.86 sec. and 66 bunches/h; and 166.93 sec. and 40 bunches/h, respectively.
