Type: crop
Model source/other links: Miller MSU, Miller et al. 2001
Calculation method: simp avg/grow
Lower threshold: 32 degrees Fahrenheit
Setting upper threshold to: 130 F (default)
Directions for starting/BIOFIX: planting date
No starting/BIOFIX date, set to: default date 4 1
Ending date: 7 0
Model validation status: partly validated
Region of known use: Montana
==============================EVENTS TABLE================================
1. 340 DD after biofix 0.9-germination: shoot breaks through soil
2. 410 DD after biofix 1.1-1st true leaves unfolded and < 1.5 inches long
3. 1160 DD after biofix 3.1-rosette stage, immature primary bud increases to max diameter
4. 1900 DD after biofix 5.1-bud initiation, miniature floral head about .25 inches diameter
5. 2270 DD after biofix 6.1-secondary branches beginning to form from top down
6. 2650 DD after biofix 7.1-onset of anthesis, 1-10% flowering
7. 2950 DD after biofix 7.9-anthesis complete when all florets have wilted
8. 3320 DD after biofix 8.9-seeds are mature when the seed hull loses opaqueness. Little green color on lvs and heads
9. 3431 DD after biofix 9.2-Direct harvest. Most of leaves brown with hint of green. Plants dry not brittle, seeds rub easily from heads
