TEMPERATURE SUM MODELS FOR PREDICTING THE DATE OF HARVEST OF VINING PEAS

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.
