Corn stand refers to the number of plants that successfully emerge after planting compared to the intended seeding rate. A strong corn stand ensures optimal yield potential, while poor stands can lead to lost profits. Checking your corn stand helps identify gaps, disease issues, corn pest challenges, or planting errors early—so you can take action before it’s too late.
How to Check Your Corn Stand
Corn stand evaluations typically occur once seedlings have fully emerged usually between V2 and V3 growth stages. Here’s how to check:
- Use the 1/1000th acre method: Measure 17.5 feet in a 30” row, count the emerged plants, and multiply by 1,000.
- Perform stand counts in five random areas of the field for accuracy.
- Compare actual emergence to your planted rate.
Modern tools have made the process faster and more precise. For example:
Tools like germination scoring on seed tags help calculate expected vs. actual stands.
Drones with multispectral imaging can scan entire fields and identify emergence gaps.
Optimizing Corn Population for Maximum Yield
Your ideal seeding rate depends on several factors:
- Choosing the right corn population depends on several factors:
- On alkaline or heavy soils, increase seeding rates for better stand establishment.
- In fields with historically large corn plants, reduce population to prevent lodging.
- For late plantings (after mid-June in California), decrease seed populations to reduce stress and maturity risk.
- Always check germination rate on the seed bag. For a 32,000-planting target and 95% germ rate, set your seeder to 33,684 seeds/acre (32,000 ÷ 0.95).
