Regional conditions, varietal spread and output: olive growing in the Mediterranean
Measured values
The only published figure for Büyük Topak Ulak is its oil content, and two independent sources agree: one gives 20.2%, the other "around 20%".
That places it among the moderately oily varieties of the Mediterranean region. For comparison, Sarı Ulak stands at 19%.
The sources describe the fruit as large with a stone that is small relative to the fruit, and the flesh as soft. That description suggests a high flesh ratio — but no measured flesh ratio has been published, so we give no figure.
⚠ No published measurement exists for fruit weight, flesh-to-stone ratio or chilling requirement. These have not been estimated.

Locally
Büyük Topak Ulak originates in Tarsus; it is also grown in Seyhan, İskenderun, Anamur, Erdemli and the Sütçüler district of Isparta. In some localities it is known as Topak Aşı.
Its range follows the Mediterranean coastal line. Its presence in Isparta is notable: the province entered olive growing late, through a ministry-backed sapling programme concentrated in the Sütçüler district.

What is an olive pit good for?
The pit makes up 13-30 percent of the fruit and its measured calorific value is 4,674 kcal/kg. But the laboratory result upsets intuition: the largest contribution to pomace energy comes from the flesh, not the pit. In activated carbon it yields 1,275 m²/g of surface area; in the nursery it is a seed that germinates poorly and demands grafting. Turkey produces roughly 200,000 tons of pomace a year.
