How to produce good seed

Ten steps for farmers to produce their own good seed

  1. Select a fertile field.
  2. Use clean, good quality seed.
  3. Plow, puddle and level the field well to control weeds and improve water management.
  4. If transplanting, plant young (15−20 d) seedlings from a healthy, weed-free nursery at two per hill at 22.5 cm x 22.5 cm spacing.
  5. Apply balanced nutrients (Nitrogen, Phosphorous, Potassium, Sulfur, and Zinc) as per crop demand.
  6. Keep the crop free of weeds, insect pests and diseases.
  7. At maximum tillering and flowering, rogue off-types (by plant height, appearance, flowering time, etc.) and poor, diseased or insect damaged plants, or plants with discolored panicles.
  8. Harvest at full maturity and 20−25% moisture content (80−85% of the grains are straw-colored).
  9. Thresh, clean, dry (12−14% moisture content), grade and label the harvested seed.
  10. Store the labeled seed in sealed clean containers placed in a cool, dry, and clean area.
