The primosole is a hybrid of the Carvalhais tangerine and the satsuma Miho that was selected by the University of Catania in the 80s. It most likely surpasses both its parents in quality and it has the great advantage of being very precocious, in fact in Sicily it gets harvested before the end of September. The average weight of this fruit is about 150 g, it does not have seeds, the peel is deep orange and thin, and easy to remove. The taste is pleasant but not comparable to the Nova, and it owes its success primarily to its precociousness. It often ripens multiple blossoms hence the harvest can occur throughout all of October. It is best not to go too far with this harvest because the fruits have the tendency to become dry. Our agricultural producers cultivate about 600 of these trees in the area of Carlentini, production is abundant and, considering the scarce stamina of this tree, the harvest turns out to be somewhat expensive due to the fact that it occurs in multiple times as the fruits continue to ripen. The fertilization is the same as for other citruses, meaning well seasoned compost, residue and mulching with hay and straw.
