Sorghum
Scientific Name: Sorghum bicolor
Description
Sorghum is a cereal grain that is cultivated for food, animal fodder, and biofuel. Characterized by its tall, grass-like appearance, it can grow up to 4 meters (13 feet) in height and features broad leaves and a large, dense flower head known as a panicle. Sorghum is notable for its resilience in arid conditions and is often used in parts of the world where water is scarce.

Planting
When
- Spring to early summer is the ideal time for planting sorghum, typically when soil temperatures reach at least 60�F (15�C).
How
- Select a well-drained site with full sun exposure.
- Prepare the soil by tilling and removing any debris.
- Plant seeds about 1 inch deep and 6-12 inches apart, depending on the variety.
- Water lightly after planting, ensuring seeds are not disturbed.
Care
Watering
- Sorghum is drought-tolerant; however, consistent watering is essential during early growth. Provide about 1 inch of water weekly if rainfall is insufficient.
Thinning
- Thin seedlings to maintain approximately 10-15 inches of space between plants for optimal growth.
Weeding
- Regularly remove weeds to reduce competition for nutrients and water. Mulching can help suppress weed growth.
Mulching
- Apply a layer of organic mulch such as straw or wood chips around the base of plants to retain moisture and control weeds.
Fertilizing
- Fertilize using a balanced fertilizer (N-P-K) after the plants are established, following the manufacturer's instructions.
Pest Management
- Monitor for common pests like aphids and sorghum midge, using organic insecticides or natural predators as needed.
Harvesting
- Sorghum is typically harvested when the grains are hard and the stalks begin to dry. This usually occurs 100-120 days after planting.
Common Problems
- Leaf spot diseases
- Fungal infections
- Shattering of grains
- Pests, including birds and insects
