Heat Units and predictions of key events from daily weather data
==============================MODEL INPUTS================================
Model species/general links: chick pea Desi
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. 280 DD after biofix 0.9-germination: shoot breaks through soil
2. 350 DD after biofix 1.1-1st true leaves unfolded
3. 440 DD after biofix 1.4-4th true leaves unfolded
4. 1610 DD after biofix 5.1-flower buds just visible (look inside axillary buds)
5. 1920 DD after biofix 6.1-10% of flowers visible, 13 to 14 nodes
6. 2240 DD after biofix 7.1-10% of pods are solid to touch
7. 2810 DD after biofix 8.9-90% pods solid to touch. Only upper parts of plant may still be green
8. 3060 DD after biofix 9.7-vines, pods, and seeds ripe and dry, 18% moisture
