Croptime introduces degree-day (DD) models for vegetable varieties and weeds. Vegetable models can help schedule planting dates and predict harvest dates. Initial findings indicate that DD models are more accurate than calendar days at predicting harvest. Weed models can predict development of first germinable seed, and help reduce the risk of weed seed rain. To date we have:
Four transplanted broccoli models
One transplanted and six direct-seeded cucumber models
Three models predicting first viable seed set for hairy nightshade, lambsquarter and redroot pigweed
New models will be posted online when available. Sweet pepper and sweet corn models are coming soon. Spinach, carrot, parsnip, lettuce, cauliflower, cabbage, kale, summer squash, snap bean and tomato models will be online by spring 2017.
If you have questions or comments or are interested in helping to collect data for new Croptime models, please contact Nick Andrews for more information.
