Use of Heat Units to Predict Dates for Once-Over Tomato Harvest

Year: 1968

Type: article

Abstract: The use of degree-day accumulations showed little advantage over calendar days when the ease of calculation for calendar days was considered. Calendar day measurements appeared to be more practical and more reliable than degree days. However, when calendar days from transplanting were compared to calendar days from the date that the stem stopped enlarging, it was found that the latter criterion was more reliable for estimating the time when the earliest maximum yield occurred. In fact, it was the most reliable criterion of many that were studied (1). Similar results were reported by Vollbrecht (5), however he stated that a more practical method is still needed to predict optimum harvest periods.
