Planting date
| Historical and suggested sunflower planting dates, listed by Agricultural Statistical Reporting Service reporting region, are shown at the following links (table 1). This data helps determine planting strategies when seeding is delayed or if replanting following hail or a hard freeze. |
| The number of days remaining to the first fall freeze of 28o F. for a given date and location are listed at the following links (tables 3a-3b). This data helps to identify crops or varieties that will likely mature before the first fall freeze. This information is critical when selecting seed of a crop or variety for planting when normal planting is delayed or if replanting following hail or a hard freeze. |
|
Late-seeding options for delayed seeding or for replanting are indicated at the following links (tables 4a-4c). Options include row crops, alternative crops, and crops used for forage. |
Planting rate & Plant density
| Unit (seed or plant) populations per acre and per foot-of-row for rows spaced on 15 to 38" centers (tables 1a - 1b) are listed at the following links. These tables help determine field populations and emergence percentages. |
