Rice Cultivation: From Field to Table
The cultivation process involves several stages, each crucial for producing high-quality rice grains.
Preparation and Planting
- Selection of suitable land with adequate water supply.
- Land preparation involving plowing and leveling.
- Seed selection based on desired traits and climate.
Growing Conditions
- Prefers warm, humid climates.
- Requires flooded fields (paddies) to control weeds and pests.
- Optimal temperatures: 20-35°C (68-95°F).
Harvesting and Post-Harvest
- Harvested when grains mature, typically using combine harvesters.
- Threshing separates grains from stalks.
- Drying reduces moisture content to prevent spoilage.
- Milling removes husk and bran layers to produce edible rice.
