Bolu Çivril Bean is a medium-late maturing, climbing variety of Phaseolus vulgaris L. It has been officially registered as a geographical indication under Law No. 6769 on Industrial Property and granted geographical indication protection on 20 August 2020. The registration application was submitted by the Bolu Bağışçılar Vakfı, and the production area is limited to the villages of Çivril, Ağaçcılar, Yazıören, Saraycık, Tatlar, Yakabayat, Çampınar and Köprücüler under the central district of Bolu Province.
Bolu Çivril Bean is recognized by its small, white, oval-shaped and glossy seeds. Its thin skin allows for easy cooking. This bean can be consumed fresh or dried and exhibits high yield and quality due to the influence of the transition zone climate. Particularly during autumn months, mild daytime temperatures and cool winds play a decisive role in achieving plump and glossy seeds.
Among its botanical traits, pole-type growth, pyramid-shaped development and early twining behavior are prominent. Anthocyanin formation is not observed in the hypocotyl. Flowers are white, pods have a green background, are glabrous and slightly inwardly curved. Pod tips transition from pointed to blunt. Seeds are sugar-shaped, white in color and sparsely veined.
In terms of physical parameters, plant height ranges from 214 to 470 cm, and the first pod height varies between 6 and 50 cm. Each plant produces 15 to 32 pods, containing 51 to 138 seeds with a seed yield of 40 to 88 grams. The weight of 100 seeds ranges from 45.0 to 72.8 grams; fresh weight from 95.1 to 146.0 grams; and dry weight from 45.9 to 75.4 grams.
The production process begins in autumn with the application of 2 to 3 tons per hectare of animal manure to the field. The soil is deeply plowed and worked with a cultivator during March–April to prepare for sowing. Sowing takes place between late April and late May. Seeds are planted at a depth of 2 to 3 cm, with row spacing of 45 to 50 cm and inter-row distance of 70 cm, placing 3 to 4 seeds per hill.
Due to its climbing habit, poles are installed for Bolu Çivril Bean in mid-June. Irrigation is carried out 14 to 16 times during the growing season using sprinkler, flood or drip methods. Weed control is performed through physical means; chemical methods are applied only when necessary for disease and pest management.
Harvesting begins at the end of July and continues manually until the first frost in autumn. In addition to fresh consumption, the beans are also dried. Dried products are manually sorted, cleaned and prepared for marketing. A portion is retained for seed use.
The monitoring process is conducted by a five-member committee composed of representatives from the Bolu Provincial Directorate of Agriculture and Forestry, Bolu Chamber of Agriculture, Bolu Agricultural Credit Cooperative and the Bolu Bağışçılar Vakfı, under the coordination of the Bolu Bağışçılar Vakfı. Monitoring is carried out annually on a regular basis and may be conducted at any time upon complaint. During inspections, the physical characteristics of the product, compliance with the production method and the correct use of the geographical indication emblem are verified.
