Planting Methods
Two primary methods are used for planting cotton: direct sowing and transplanting.
- Direct Sowing: Involves planting seeds directly into the prepared field. This method is often preferred for its simplicity and cost-effectiveness, particularly in large-scale operations. Seeds are typically planted in rows, ensuring even spacing and minimizing competition for resources. The soil should be moist enough for the seeds to germinate, but not waterlogged.
- Transplanting: Involves growing seedlings in a nursery bed before transferring them to the field. This method can be advantageous in areas with a short growing season or when dealing with specific pest or disease issues. Seedlings are typically transplanted when they have reached a certain size and stage of development, typically 4-6 weeks old, with 2-4 true leaves.
Planting Spacing
Proper spacing is crucial for optimal plant growth and yield. Too close planting can lead to competition for resources, hindering individual plant development and reducing yield. Conversely, overly wide spacing can lead to wasted land and potentially reduced yields due to the increased risk of weeds. The specific spacing requirements vary depending on the variety of cotton and the specific growing conditions.
Generally, recommended spacing is around 30-45 cm between plants and 60-90 cm between rows.
