Abstract
The total nutritionalloss in an avocado trae due te abscission of buds, flowers, fruiUets and fruits is relatively small. Only 25.8 kg.ha.1 N, 3.7 kg.ha.1 P and 31.0 kg.ha.1 K are found in the abscissed organs. Among the microelements Fe is lost 7 to 50 times more than the other microelements (1.40 kg.ha.I). No relationship was found between the nutrients and the previous or future yield except for phosphorous. Decrease in P level in the flowers was followed by an increase in yield the following winter. The small nutritionalloss seems to be of minor importance as a factor in avocado productivity.
