Harvesting banana crops primarily involves carefully cutting down the mature bunches from the plant at the optimal time, ensuring the fruit is still green but fully developed for artificial ripening.
When to Harvest Bananas: Key Indicators
Knowing the right time to harvest is crucial for fruit quality. Bananas are typically harvested while they are still raw (green) and firm, as they will then be ripened artificially later. Several factors influence the timing of harvest:
- Plant Type:
- Dwarf Banana Cultivars: These varieties are generally ready for harvest relatively sooner, typically within 11 to 14 months after planting.
- Tall Banana Cultivars: These take a bit longer to mature, usually requiring around 14 to 16 months from the time of planting to harvest.
- Bunch Maturity:
- After the banana flower (or "shooting") appears, a bunch usually takes 90 to 120 days to mature sufficiently for harvest. This timeframe can vary based on local climate conditions and the specific cultural practices employed by the farmer.
- Physical Signs: Harvesters look for the fullness of the individual bananas (fingers). The edges of the bananas should appear rounded rather than angular, indicating they are filled out, even if still green. The top hands of the bunch usually mature first.
The Banana Harvesting Process
The actual process of harvesting banana crops requires care and precision to avoid damaging the fruit and to ensure safety.
-
Assessing Maturity:
- Inspect the bunch for the characteristic rounding of the individual bananas, especially in the top "hands" (clusters of bananas). The peel should still be uniformly green.
- Confirm the plant type and its expected maturity period as outlined above.
-
Preparing for the Cut:
- Ensure the ground around the plant is clear.
- Position a padded landing area (e.g., old sacks, leaves) beneath the bunch to cushion its fall and prevent bruising.
- Have a helper ready to receive the falling bunch, or use specialized tools.
-
Making the Incision:
- Partial Stem Cut: Using a long-handled sharp knife or a specialized banana harvesting tool (often a machete attached to a pole), make a partial cut into the stem of the banana plant about 2-3 feet below the bunch. This allows the plant to bend slowly and gently lower the bunch towards the ground.
- Controlling the Descent: As the plant bends, the harvesters can carefully guide the bunch down. This prevents a sudden drop which could bruise the fruit.
- Final Cut: Once the bunch is within reach or resting on the ground/padding, a second, complete cut is made above the top hand of bananas to detach the bunch from the plant stem.
-
Handling the Harvested Bunch:
- Handle the bunch with extreme care to prevent bruising, which can negatively impact the fruit's quality and market value.
- Transport the bunches to a collection point or packing shed as soon as possible.
-
Post-Harvest Plant Management:
- After harvesting, the mother plant (the stem that bore the fruit) is typically cut down. This allows the "sucker" or "ratoon" plants growing from the base to become the next productive stems, continuing the cycle.
Table: Banana Harvest Maturity Timelines
Cultivar Type | Time After Planting (Approx.) | Bunch Maturity After Shooting (Approx.) | Key Indicators |
---|---|---|---|
Dwarf Bananas | 11-14 months | 90-120 days | Green, rounded fingers |
Tall Bananas | 14-16 months | 90-120 days | Green, rounded fingers |
Importance of Artificial Ripening
As bananas are harvested raw, they require artificial ripening. This process is crucial for commercial distribution. After harvest, bananas are often transported to specialized ripening chambers where controlled levels of ethylene gas are introduced. Ethylene is a natural plant hormone that triggers the ripening process, ensuring the bananas develop their characteristic yellow color, sweet flavor, and soft texture uniformly and efficiently before being sent to markets.
