Pigeon pea

cultivation of Pigeon pea

Pigeon pea (Cajanus cajan) is a versatile crop that is relatively easy to cultivate. Here is an overview of the cultivation process:

1. Soil Preparation: For optimal growth, pigeon pea thrives in well-drained soils that possess a pH range of 5.5 to 7.5. The land intended for cultivation should be cleared of any debris, rocks, or weeds, and plowed to a depth of approximately 15-20 cm.
2. Planting: The pigeon pea seeds may either be directly sown into the soil or started in pots and then transplanted when they reach an appropriate size. It is recommended to plant them at the start of the rainy season, as sufficient water is essential for germination and initial development.
3. Fertilization: Although pigeon pea doesn't require much fertilizer, incorporating organic matter into the soil can enhance their fertility. Applying compost or manure before planting can provide the plant with the necessary nutrients to thrive.
4. Watering: Pigeon pea requires regular watering, especially during the early stages of growth. It is important to ensure that the soil stays moist, but not waterlogged.
5. Weed Control: Weeds can compete with pigeon peas for nutrients and water, so it is important to keep the area around the plants clear of any weeds. This can be done by hand or with a hoe and should be done regularly throughout the growing season.
6. Harvesting: Pigeon pea is ready to harvest when the pods have turned brown and the seeds inside are hard. The pods can be harvested by hand, and the seeds can be dried in the sun before being stored for later use.

As a crop, pigeon pea requires relatively low maintenance and can be cultivated in diverse soils and climates, rendering them a significant food crop for various parts of the world.
