ABSTRACT
The study was conducted to design, and develop a machine for planting
garlic. Made of locally-available materials, the machine was
designed simply so that it is compact and
portable. Its laboratory performance was evaluated in terms
of bulblet delivery rate, delivery accuracy, and the amount of
damaged bulblets. There were three garlic varieties used in the
evaluation namely, Ilocos White,
Tan Bolter and Taiwan.
Results of the preliminary test
revealed that the average delivery rate of the prototype using
bulblets of Ilocos White, Tan Bolter and Taiwan varieties were
283.86 kg/ha, 155.20 kg/ha, and 416.10 kg/ha, respectively with
accuracies of 91.57 %, 95.30%, and 74.76
%. The amount of damaged bulblets caused by the metering mechanism
of the prototype were:
1.92% for Ilocos White variety, 2.06% Tan Bolter variety, and
11.75 % fir Taiwan variety.
The fabrication cost of the prototype garlic planter was P15,000.00
which cover the materials, labor, contingency and miscellaneous
costs. Results of the economic analysis using financial investment
method showed the break-even periods of 0.20 year, and 0.63 year
when using the prototype planter to plant Ilocos White, and Tan
Bolter varieties, respectively. Planting Taiwan variety using the
machine is not economically feasible because of high rate of
damaged gloves caused by the metering mechanism of the machine.
