Certified Rice Seed IR 50404
IR 50404 is a short-duration certified rice variety known for straightforward cultivation, broad adaptability and reliable yield.
- CropRice (Oryza sativa)
- Seed typeCertified seed
- Growth period85–90 days
Overview
Its compact plant form and tolerance of mildly acidic soils make it a practical option for efficient production cycles.
Certified seed is produced under field inspection and laboratory testing for varietal purity and germination, so every bag gives an even, true-to-type crop. Sowing certified seed is the simplest way to protect yield, grain quality and the price the harvest fetches.
Key features
- Short 85–90 day cycle for fast rotations
- Easy to grow and widely adaptable
- Tolerates mildly acidic soils
- Long grain that stays firm when cooked
- Certified seed, tested for varietal purity and germination
Growing guide
- Seed and landSoak and incubate the seed until it just sprouts. Level the field and drain it well so seedlings establish evenly, whether you broadcast, drum-seed or transplant.
- Seed rateSow thinly: a moderate seed rate gives sturdier tillers, better airflow and less disease. Drum or cluster seeding saves seed and makes the crop easier to manage.
- NutritionSplit nitrogen into several doses through tillering and panicle initiation and balance it with phosphorus and potassium. Avoid heavy late nitrogen, which invites lodging and pests.
- WaterKeep a shallow water layer after establishment and use alternate wetting and drying where you can: it saves water and cuts methane emissions. Drain the field 7–10 days before harvest.
- Crop protectionScout weekly for brown planthopper, leaf folder, blast and bacterial leaf blight, and spray only when local thresholds are reached, following plant-protection advice.
- HarvestHarvest when 85–90% of the grains on the panicle have turned straw-yellow, then dry the paddy promptly to about 14% moisture for storage.
