❓ Frequently Asked Questions

What is seed rate?

Seed rate is the quantity of seeds (in kg) required to sow one hectare or one acre of land. It varies by crop, variety, sowing method, and expected germination percentage. ICAR provides recommended seed rates for all major Indian crops.

Why does the seed rate vary with sowing method?

Different sowing methods have different spacing and seed placement requirements. Broadcast sowing requires more seeds because seeds are scattered randomly with lower germination efficiency. Drill/line sowing is more efficient, and transplanting requires the least seeds as seedlings are raised separately in nurseries.

What is seed treatment?

Seed treatment involves applying fungicides, pesticides, or biological agents to seeds before sowing to protect against soil-borne diseases, pests, and improve germination. Common treatments include Thiram (2g/kg), Captan (2g/kg), or Trichoderma viride (4g/kg) for fungal protection.

How does germination percentage affect seed rate?

If seed germination is less than 90%, you need to increase the seed rate proportionally. For example, if standard rate is 100 kg/ha and germination is 80%, use 100 × 90/80 = 112.5 kg/ha. Always buy certified seeds with labeled germination percentage.

What is the difference between certified and truthfully labelled seeds?

Certified seeds (white tag) meet the highest quality standards set by State Seed Certification Agencies with guaranteed germination, purity, and moisture content. Truthfully Labelled (TL) seeds have the seller's guarantee. For best crop establishment, always use certified seeds from authorized dealers.
