| Abstract: |
| Transplantation is one of the most effective methods to increase economic efficiency of some agricultural products like rice, onion, vegetables. The present study evaluated a semi-automatic and self-propelled new transplanter for bare-root onions seedlings. Each planter features a carrousel with cells that are manually fed by a worker. To evaluate the machine and determine the optimum conditions, the effect of two factors of forward speed at three levels (0.16, 0.21 and 0.28 Km/hr) and depth of work at two levels (3 and 6 cm) on the parameters miss index, multiple index, quality of feed index precision index and field capacity were studied. The results showed that the depth of work only had a significant effect on the accuracy index, so that the accuracy index decreased with the increase of depth of work. Forward speed change had a significant effect on miss index, multiple index, quality of feed index (p<0.05) and had no significant effect on precision index. Increasing the forward velocity from 0.16 to 0.28 km/h, increased miss index 75.5% and multiple index 69%, but quality of feed index decreased 17.4%. The optimum speed for transplanting onions with this machine was 0.21 km/hr. At this rate, feeding index, miss index, multiple index, precision index and field capacity were 87.45, 6.17, 3.4, 9.1% and 0.031 ha/hr respectively. |
