Introduction to Upland Rice (Pa-le)
Upland Rice, often referred to as Pa-le, is a variety of rice that is cultivated primarily in dryland, non-flooded fields. Unlike its lowland counterparts, Upland Rice can be grown under pluvial conditions and in well-drained, elevated areas. This adaptability makes it a valuable crop for farmers in regions where water resources are limited.
Botanical Profile of Upland Rice (Pa-le)
The scientific name of Upland Rice is Oryza sativa. It is a member of the Poaceae family, known for its versatility in various climatic conditions. Upland Rice plants typically grow to a height of 1 to 1.5 meters. The grains are usually smaller and have a tougher husk compared to lowland rice varieties.
Soil, pH, and Climate Requirements for Upland Rice (Pa-le)
Upland Rice requires specific soil and climate conditions to thrive optimally. The table below provides a detailed outline of the ideal growing conditions:
| Parameter | Ideal Range |
|---|---|
| Soil Type | Loam, Sandy Loam |
| Soil pH | 5.0 - 6.5 |
| Temperature Range | 21°C - 32°C |
| Annual Rainfall | 800mm - 1200mm |
Step-by-Step Planting & Propagation
- Soil Preparation: Begin by preparing your soil to ensure it is well-drained and nutrient-rich. A sandy loam or loam soil type is ideal.
- Sowing Seeds: Plant seeds 1-2 cm deep into the soil. Use a seed rate of approximately 50 kg per hectare.
- Spacing: Ensure rows are spaced at about 25-30 cm apart with seeds spaced at 15-20 cm intervals.
- Propagation Method: Upland Rice is predominantly propagated through direct seeding rather than transplanting.

Harvesting, Curing & Optimal Storage
- Harvesting: Upland Rice is ready for harvest when grains turn golden brown, approximately 120 days post-sowing.
- Curing: Dry harvested rice in the sun for 2-3 days. This reduces moisture content and prevents mold.
- Storage: Store cured rice grains in a cool, dry place in airtight containers to prolong shelf life.
Companion Planting for Upland Rice (Pa-le)
Companion planting can enhance Upland Rice yields and deter pests. Suitable companions include Lettuce, coriander, and beans. Avoid planting with tall crops like Corn that can overshadow the rice.
