30. Summary & Conclusions • General results show a trend toward advantage to the PON (spring application) under OFF year (increase in fruit Nr) and yield increase of53% - 56% against 33% in the summer spray. • Under ONyear, the advantage is to the SON - summer spray (increase in fruit size), and the added yield is about 43% against 16-25% of the spring application. • There is no marked advantage to the double spray (PON +SON) over a single application with the right product at the right season (On/Off), and the added yield does not pay the cost of the additional spray. • The NutriVant foliar sprays on OLIVE trees have not show an influence on either the oil percentage or the oil quality. • In Oil Olives, the increase in Oil quantity, is subjected to the • Increase in fruit yields.
