This is done according to standard operating procedures (SOPs), with specific timed intervals between each round of harvesting. During bunch sampling, observations are conducted on the status of the bunches, e.g....

Cover for Fruit sampling.

Both nut analysis and oil analysis require proper sampling. Fertile fruits without any damage (bruising or chopped) are sampled using a randomization box. The randomization box divides the fruit sample into two portions (into two container boxes). Thirty fruits are taken randomly from each box and...

Cover for Pollination.

Pollination is controlled through a window in the specialized isolation bag; this reduces the risk of contamination (foreign pollen, disease and insects). Prior to pollination, the area around the isolation bag is sprayed to kill insects, as these can carry unwanted pollen. Pollen is normally mixed ...

Cover for Harvesting.

The ripe bunch with red-coloured fruits can be harvested about 150 days after pollination, or when one loose fruit appears on the ground. Harvested bunches are sent to the processing area in gunny sacks, along with any loose fruit that detach during harvesting. Minimum ripeness standards are used...
