In this study, experimental field trials were conducted at National Root Crops Research Institute (NRCRI),
Umudike, on a flat land with sandy clay loam soil, to evaluate the performance of the machine at two different
tractor forward speeds of 4km/h and 8km/h. The following field parameters were recorded: operation speeds,
number of ginger rhizomes harvested, number of un-harvested ginger, number of ginger rhizomes with cut,
effective/theoretical field capacity and efficiency. Harvesting of ginger rhizomes in Nigeria is done manually by
the use of fork, spade and other farm implements. A Randomized Complete Block Design (RCBD) was used to
design the experiment and analyses carried out with Analysis of Variance (ANOVA). From the results, the tractor
forward speed of 4km/h has the highest number of ginger rhizomes harvested at 88.7%, while the speed of 8km/h
has the highest number of un-harvested ginger at 31%, and number of ginger with cut at 33.7%. The harvester
gave a satisfactory performance as it was able to carry out harvesting operation of ginger, with the effective field
capacity, theoretical field capacity and field efficiency of 0.0261ha/h, 0.000505ha/h and 52% respectively.
