Suruç Pomegranate (Punica granatum L.)

Suruç Pomegranate (Latin scientific name: Punica granatum L.) is a variety of pomegranate cultivated within the boundaries of Şanlıurfa province, particularly renowned in the Suruç district. It is a highly valued agricultural product in the region due to its color, taste, and aroma. It was officially registered on 27 July 2021 by the Suruç Municipality for protection, effective from 17 July 2020. Its registration number is 812 and the type of geographical indication is "Place Name".

Distinctive Characteristics

The Suruç Pomegranate is a large to medium-sized fruit with a skin color featuring red and pink tones over a yellow base. Its arils are large and easily separable. With soft seeds and a sweet, pleasant flavor, it is predominantly consumed as a table pomegranate.

The Suruç Pomegranate acquires its unique characteristics due to the climatic conditions of its growing region (microclimate), the permeable moist and cool soil structure, dry air conditions during fruit development, and ideal sunlight exposure. Approximately 60% of the fruit’s weight consists of arils. These arils are soft, pink to light red in color, and the fruit has a medium-thin, elastic skin.

The juice yield of the Suruç Pomegranate is at least 45%. In terms of acidity, it falls within both the sweet pomegranate group (titratable acidity less than 1% citric acid) and the semi-sweet pomegranate group (titratable acidity between 1% and 2% citric acid). The fruit weight ranges from 250 to 650 grams. Its shape is not perfectly spherical but slightly flattened along the stem and calyx axis. The soluble dry matter content (Brix value) is at least 15%, and the phenolic compound content is at least 1300 mg/L. The main organic acids present are citric acid, ascorbic acid, and malic acid, while the primary phenolic compounds are quercetin, caffeic acid, and catechin.

Production Method

The Suruç Pomegranate is a perennial, shrub-like plant with a strong root system, multiple trunks, and dense branching. Its fruit is large and slightly flattened spherical in shape. It is a hardy crop that can withstand temperatures as low as −10°C, thrives under various climatic and soil conditions, requires minimal maintenance, remains on the tree for extended periods, and is suitable for storage. The specified geographical area offers highly favorable climatic conditions for pomegranate cultivation during summer and autumn months. Annual average rainfall of 500 mm is sufficient, but spring rainfall is preferred. Dry air conditions during fruit development positively influence fruit quality.

• Orchard Establishment: The planting site is leveled and deeply tilled. Planting pits of 40–60 cm depth and diameter are dug during autumn. The pits are filled with topsoil mixed with well-composted farmyard manure. Spacing between plants varies from 2 m to 6 m (ideally 3×3 m or 3×4 m). Rows are typically oriented north-south to ensure effective air circulation and sunlight exposure. Orchards are generally established using container-grown seedlings.

• Soil and Climate Requirements: The Suruç Pomegranate is not selective regarding soil type and can be grown in various soils including siliceous, stony, sandy, calcareous, and clayey types. It grows well in both alkaline and acidic soils, exhibits moderate tolerance to salinity, and is resistant to excessive soil moisture. It shows optimal growth under dry and warm air conditions with permeable, moist, and cool soils.

• Pruning: Shape pruning is carried out during the first 2–3 years before the trees begin to bear fruit. After planting, 3–4 vigorous shoots emerging from the base are selected as main trunks and their tops are cut at 50–60 cm to form low canopies. In yield pruning, the tips of fruit-bearing branches should not be removed. The Suruç Pomegranate typically begins fruiting from the third year onwards. For rejuvenation pruning, older trunks are cut at the base to encourage new shoot development. Yield may decline after an average of 20 years.

• Fertilization: It is recommended to apply 2–3 tons of well-composted farmyard manure per hectare during autumn and winter, and incorporate it into the soil using harrowing. Nitrogenous fertilizers are applied twice, in early spring and early summer. Phosphorus fertilizers are essential for flowering, fruit set, and root development.

• Irrigation: The plant prefers moist and cool soil conditions. Irrigation is necessary during periods of insufficient rainfall. Frequent but light irrigation is recommended (typically every 7–10 days). Irrigation should be stopped 10–15 days before harvest to prevent skin cracking of the fruit.

• Plant Protection: Plant protection products are applied in accordance with relevant legislation. Weeds are controlled mechanically using tractors or hand hoes.

• Harvesting: Harvesting typically begins at the end of August and continues until mid-November. Harvesting must be completed before early autumn frosts and rains and should be done manually using shears. Harvested fruits should be gently placed in crates, taking care not to damage the calyx portion.

Storage and Preservation Conditions

The Suruç Pomegranate can be marketed for extended periods using modern preservation methods. In cold storage, it can be kept for up to six months in food-grade plastic bags at approximately 6°C and 85–90% relative humidity, or up to seven months using modified atmosphere packaging (MAP). Under traditional storage, sound fruits can be stored for up to two months in clean, dry, cool, and shaded environments, either displayed or packed in crates.

Monitoring

Monitoring of the Suruç Pomegranate geographical indication is carried out by a monitoring body consisting of at least three members, coordinated by the Suruç Municipality, with participation from one representative each of the Suruç Municipality, Şanlıurfa Provincial Directorate of Agriculture and Forestry, Suruç District Directorate of Agriculture and Forestry, and the Faculty of Engineering at Harran University. Monitoring is conducted at least once annually and reported in accordance with Law No. 6769 on Industrial Property, and submitted regularly each year to the Turkish Patent and Trademark Office. The monitoring body verifies compliance with the approved usage of the geographical indication, as well as adherence to harvesting, storage, and preservation conditions and the production methods outlined in the "Production Method" section.
