Pigeon peas, also known as toor dal or red gram, are a versatile and nutritious legume that is widely cultivated in many parts of the world. They are a staple crop in many tropical and subtropical regions, and are valued for their high protein content, fiber, and other essential nutrients. However, knowing when to harvest pigeon peas can be a bit tricky, as the timing of the harvest can affect the quality and yield of the crop. In this article, we will explore the different stages of pigeon pea growth, and provide guidance on how to determine when they are ready to pick.
Understanding the Growth Stages of Pigeon Peas
Pigeon peas are a warm-season crop that typically takes around 120 to 150 days to mature. The growth stages of pigeon peas can be divided into several distinct phases, including germination, seedling establishment, vegetative growth, flowering, and pod formation.
Germination and Seedling Establishment
The first stage of pigeon pea growth is germination, which typically occurs within 7 to 10 days after sowing. During this stage, the seeds absorb water, and the embryo begins to grow. The seedling establishment stage follows germination, during which the seedlings develop their root system and first set of leaves.
Vegetative Growth
The vegetative growth stage is the next phase of pigeon pea growth, during which the plants develop their stem, leaves, and branches. This stage typically lasts around 30 to 40 days, and is characterized by rapid growth and development.
Flowering and Pod Formation
The flowering stage is a critical phase of pigeon pea growth, during which the plants produce flowers and eventually form pods. The flowers are typically yellow or white in color, and are self-pollinating. The pod formation stage follows flowering, during which the pods grow and mature.
How to Determine When Pigeon Peas are Ready to Pick
Determining when pigeon peas are ready to pick can be a bit tricky, as the timing of the harvest can affect the quality and yield of the crop. Here are some tips to help you determine when your pigeon peas are ready to pick:
Check the Color and Texture of the Pods
One of the easiest ways to determine when pigeon peas are ready to pick is to check the color and texture of the pods. Mature pigeon pea pods are typically brown or tan in color, and are dry and brittle to the touch. Immature pods, on the other hand, are typically green or yellow in color, and are soft and pliable.
Check the Seeds
Another way to determine when pigeon peas are ready to pick is to check the seeds. Mature pigeon pea seeds are typically hard and dry, and are a light brown or tan color. Immature seeds, on the other hand, are typically soft and moist, and are a green or yellow color.
Check the Moisture Content
The moisture content of the pods is another important factor to consider when determining when pigeon peas are ready to pick. Mature pigeon pea pods typically have a moisture content of around 20%, while immature pods have a higher moisture content.
Check the Rattle Test
The rattle test is a simple and effective way to determine when pigeon peas are ready to pick. To perform the rattle test, simply shake a pod gently. If the seeds rattle inside the pod, it is ready to pick. If the seeds do not rattle, the pod is not yet mature.
Harvesting Pigeon Peas
Once you have determined that your pigeon peas are ready to pick, it’s time to harvest them. Here are some tips to help you harvest your pigeon peas:
Cut the Stems
To harvest pigeon peas, simply cut the stems near the base of the plant using a sharp knife or pruning shears. This will help to prevent damage to the pods and seeds.
Remove the Pods
Once you have cut the stems, remove the pods from the plant. You can do this by hand, or by using a mechanical harvester.
Dry the Pods
After you have removed the pods from the plant, dry them further to reduce the moisture content. You can do this by spreading the pods out in the sun, or by using a mechanical dryer.
Thresh the Pods
Once the pods are dry, thresh them to remove the seeds. You can do this by hand, or by using a mechanical thresher.
Common Mistakes to Avoid When Harvesting Pigeon Peas
Here are some common mistakes to avoid when harvesting pigeon peas:
Harvesting Too Early
Harvesting pigeon peas too early can result in immature seeds that are not yet dry. This can lead to a lower yield and lower quality seeds.
Harvesting Too Late
Harvesting pigeon peas too late can result in over-mature seeds that are dry and brittle. This can lead to a lower yield and lower quality seeds.
Not Drying the Pods Properly
Not drying the pods properly can result in mold and fungal growth, which can lead to a lower yield and lower quality seeds.
Conclusion
Harvesting pigeon peas at the right time is critical to ensuring a high-quality crop. By understanding the growth stages of pigeon peas, and by checking the color and texture of the pods, seeds, and moisture content, you can determine when your pigeon peas are ready to pick. Remember to avoid common mistakes such as harvesting too early or too late, and not drying the pods properly. With proper harvesting and drying techniques, you can enjoy a bountiful crop of pigeon peas.

What are the signs that pigeon peas are ready to harvest?
Pigeon peas are ready to harvest when the pods turn brown and dry, and the seeds rattle inside. You can also check for readiness by opening a pod; if the seeds are hard and the color has changed from green to a more mature color, they are ready to harvest.
It’s essential to check the peas regularly, as the ideal harvest time can vary depending on factors like weather conditions and the specific variety of pigeon pea. Harvesting at the right time ensures the best flavor and texture.
How often should I check my pigeon pea plants for readiness?
It’s recommended to check your pigeon pea plants every few days, especially when they are nearing maturity. This frequency helps you catch the optimal harvest time and avoid missing it. You can also keep an eye out for visual cues like the yellowing of leaves or the drying of the stems, which can indicate that the peas are ready.
Regular checks also allow you to monitor the plants’ progress and address any potential issues that may affect the harvest. By staying on top of the plants’ development, you can ensure a successful and bountiful harvest.
Can I harvest pigeon peas when they are still green?
While it’s technically possible to harvest pigeon peas when they are still green, it’s not recommended. Green pigeon peas are typically immature and may not have the best flavor or texture. Harvesting them too early can also reduce the overall yield and affect the plant’s ability to produce more peas.
If you do choose to harvest green pigeon peas, make sure to use them immediately, as they will not store well. It’s generally better to wait until the peas have matured and dried, as this will result in a better-tasting and more versatile product.
How do I harvest pigeon peas?
To harvest pigeon peas, simply pull the dry, brown pods from the plant. You can harvest individual pods or cut the entire stem, depending on your preference. Be gentle when handling the plants to avoid damaging them and reducing future yields.
