| Abstract:
Statistical models for predicting the date of harvest of vining peas (Pisum sativum L.) were examined using observations from growers. The best predictions were obtained with a two-component model combining sowing-to-emergence soil temperature sums (base temperature 3.0 °C) with emergence-to-harvest air temperature sums (base temperature 5.5 °C) as prediction criteria. The error of prediction for this model was 5.0 days. | |
