This paper describes the labour requirement for the prenursery seedling bagging operation time required to complete different steps in this operations and physical properties of germinated oil palm seeds. Malaysia needs around 18.13 million oil palm seedling bags every year and 18900 man-days to complete the oil palm seedling bagging operation in the per nursery stage alone. Filing the poly bags with soil was the most time consuming activity followed by the planting of germinated seeds. The total time for manual method of seedling bagging was measured to be about 21 seconds to complete one bag. Out of three major unit operations involved in the seedling bagging poly bag filling and planting seeds consume 86 of the time. During these two operations the workers have to squat on the floor all the 8 hours of their working time. This causes a lot of fatigue to the workers and leads to severe pain in the knee joints. The length width thickness of the oil palm seed was 27.54mm 18.99mm and 15.79mm respectively. The equivalent diameter of the seed was 20.49mm and sphericity was 0.73. The length of plumule and radicle at 24 days after germination was measured as 23.6mm and 20.34mm respectively. In the first two weeks the growth rate of plumule was more and during the third week it was less. In contrast the growth rate of radicle was less in the beginning and more during the third week.

Abstract

This paper describes the labour requirement for the prenursery seedling bagging operation time required to complete different steps in this operations and physical properties of germinated oil palm seeds. Malaysia needs around 18.13 million oil palm seedling bags every year and 18900 man-days to complete the oil palm seedling bagging operation in the per nursery stage alone. Filing the poly bags with soil was the most time consuming activity followed by the planting of germinated seeds. The total time for manual method of seedling bagging was measured to be about 21 seconds to complete one bag. Out of three major unit operations involved in the seedling bagging poly bag filling and planting seeds consume 86 of the time. During these two operations the workers have to squat on the floor all the 8 hours of their working time. This causes a lot of fatigue to the workers and leads to severe pain in the knee joints. The length width thickness of the oil palm seed was 27.54mm 18.99mm and 15.79mm respectively. The equivalent diameter of the seed was 20.49mm and sphericity was 0.73. The length of plumule and radicle at 24 days after germination was measured as 23.6mm and 20.34mm respectively. In the first two weeks the growth rate of plumule was more and during the third week it was less. In contrast the growth rate of radicle was less in the beginning and more during the third week.
