 | | For a variable-rate seeding strategy to be effective, growers must know the relationship between plant population and grain yield for all planting zones within their fields. |
 | | Even though this 33-acre field was seeded at a uniform rate of 30,000 seeds per acre, resulting plant populations measured in individual counts varied from 21,000 to 31,000 plants per acre. |
 | | Clearly, there is considerable room for improvement in selecting seeding rates that will achieve recommended plant populations of at least 26,000 plants per acre in all parts of variable fields. |
