METHOD AND RESULTS OF THE "BAVENDORF APPLE FORECAST MODEL", AS INTRODUCED 1987 IN SANTA CATARINA (BRAZIL).

Author:

F. Winter

Abstract:
Basic elements of this Apple Forecast Model as created by the author and used every year within the main apple growing areas in Western Europe are

the yield capacity of the observed growing unit (tree, orchard, area)
the fruitset density of this growing unit in the given year
the average fruit weight at picking date.

In January 1987, the system has been introduced by the author and applied for the first time in Santa Catarina (Brazil) as a cooperation of EMPASC and ACARESC.

The calculated results of forecast show a total apple production of about 135 000 t in 1987 with a yearly increasing rate due to newplantings coming into production of about 25 000 t.
