Introduction to IR64 Rice
IR64 Rice is a renowned variety of rice that has gained significant popularity among rice farmers due to its high yield and resistance to multiple stresses. Originally developed by the International Rice Research Institute (IRRI), this rice variety offers a balanced combination of productivity and quality, making it a staple in many rice-producing regions.
Botanical Profile of IR64 Rice
IR64 Rice belongs to the species Oryza sativa and is distinguished by its semi-dwarf stature, which reduces lodging risk. It matures in about 110-120 days, making it suitable for double cropping. The grains are long and slender, providing excellent cooking quality and taste.
Soil, pH, and Climate Requirements for IR64 Rice
To achieve optimal growth, IR64 Rice necessitates specific soil, pH, and climate conditions. Here is a structured table illustrating the ideal growth parameters:
| Parameter | Ideal Condition |
|---|---|
| Soil Type | Loamy, clay loam |
| Soil pH | 5.5 - 6.8 |
| Temperature Range | 25°C - 35°C |
| Rainfall | 1200mm - 1500mm per annum |

Step-by-Step Planting & Propagation
- Seed Selection and Treatment: Choose high-quality seeds and treat them with fungicides to prevent seed-borne diseases.
- Sowing: Opt for direct seeding or transplanting methods. In direct seeding, seeds are sown directly into the field. In transplanting, start seeds in a nursery and transplant them after 20-25 days.
- Field Preparation: Prepare the field by flooding and plowing to a fine tilth. Level the field to ensure uniform water distribution.
- Transplantation: Transplant seedlings at a spacing of 20x15 cm to maintain plant density, which influences yield.
- Water Management: Manage water levels carefully to avoid water stress or excessive flooding.
- Fertilization: Follow the fertilization strategy in the next section to ensure nutrient availability throughout the growth stages.
Care & Maintenance Regimes for IR64 Rice
To ensure healthy growth and maximum yield, follow these care and maintenance schedules:
| Activity | Schedule |
|---|---|
| Watering | Maintain 5 cm water level from planting to flowering, then drain the field at maturity |
| Fertilization | Use split application: Basal NPK, top-dress nitrogen at tillering and panicle initiation |
| Pruning | Not applicable |

Pests, Diseases & Organic Management
IR64 Rice is susceptible to various pests and diseases, including blast and stem borers. Here are some methods to manage these issues:
- Blast: Use resistant varieties and apply fungicides as necessary.
- Stem Borers: Apply biological control agents like Trichogramma wasps.
To manage other pests like spider mites and leafhoppers, consider rotating crops or using organic bait methods.

Harvesting, Curing & Optimal Storage
Harvesting: Harvest IR64 Rice when 80% of the grains have matured, indicated by a golden color. Use mechanical harvesters or manual sickling methods.
Curing: Post-harvest, dry the grains to reduce moisture content to 14-15% for safe storage.
Storage: Store the dried grains in a cool, dry place in sealed containers to prevent pest and moisture damage.
Companion Planting for IR64 Rice
Companion planting enhances biodiversity and pest control. Suitable companions for rice include Lentils and Soybeans, which can fix nitrogen levels in the soil.
