PREDICTING THE HARVEST OF CYCLED ‘BEAUMONT’ GUAVA |

| Abstract:
Equations were developed to predict the beginning of harvest and 50% harvest completion from cycling (pruning and fertilizing) for guava (Psidium guajava L. ‘Beaumont’) in Hawaii. Variables in the multiple regression equations were photoperiod and the sum of the growing degree days 150 days after cycling. Harvest and weather data were obtained from two commercial farms on the islands of Hawaii and Kauai. Days to harvest and days to 50% harvest completion were predicted within mean deviations of 7 and 12 days, respectively. For the two sites photoperiod and temperature data were historical, not current season, means. Thus, predictions can be made for several years in advance. | |
