Actual conditions of harvesting and transporting in plastic houses were investigated and following results were obtained.
(1) In harvesting of cucumbers, hand-baskets were used in many houses, and simple carts were used in some houses. In harvesting of green peppers, carts are more common than hand-baskets.
(2) The harvesting time required was about 120 minutes for a man when the yield of cucumbers was 100kg per 10 a, and was about 250 minutes for a man for green peppers.
(3) The time required in harvesting unit weight (1kg) of cucumbers as well as green peppers decreased with yield up to about 100kg per 10 a. and became nearly constant beyond that yield. The time was about one minute for 1kg of cucumbers and about two minutes for 1kg of green peppers.
(4) The walking distance at harvesting varied with types of houses, and methods of harvesting and transporting.
(5) Though the investigation lacked in fatigue tests of workers, it seemed that the temperature in the house and the solar radiation had marked effects on fatigue of workers.
