Cultivation
The area of ​​interest lies in the southern part of the province of Frosinone. The area includes some municipalities in the "Valley of Comino " which are: Atina , Casalattico , Casalvieri , Gallinaro , Picinisco , Villa Latina . The territory actually suited to the cultivation of cannellini bean covers a total area of  1.500 hectares, spread in areas adjacent to the Melfa River , about 11 km, and the stream Mollarino for about 9 km in alluvial soils and wetlands.
The soil , water , microclimate , the seeds perfectly adapted to the environment soil and climate , and the type of cultivation , which requires no chemical fertilizers or organic, give the product a unique flavor .
The soil and climate makes the varieties used most hardy and therefore more resistant and sufficiently refractory to degenerative diseases of the bean, you do not need the use of synthetic chemical pesticides and herbicides almost always harmful natural humus of the soil and the health of the consumer .
The non-use of fertilizers and pesticides , for many years, has certainly helped to maintain satisfactory conditions of the land.
Throughout this area there is the culture of cannellini bean that takes on a historical- cultural as well as economic characteristic of the typical product .
The type of agricultural enterprises is mostly made ​​up of family farms , with maximum surface area of between 4-8 ha.

Cultivation technique
( Summary from the proposed production regulations of the Protected Designation of Origin " Cannellini Atina " dell'ARSIAL )

The last ten days of June is the period of sowing canon for the cannellini beans . It requires a careful preparation of the seed bed with plowing or digging depth of 35-45 cm . The bean ' Cannellini Atina "is a summer crop of second harvest planted in succession to a grass Autumn and Winter rape is never repeated on itself. The seeds must be placed at the base of the groove at an average depth of 5-6 cm , the distance between the rows is about 50 cm . and 5-6 cm on the row .
It has moderate water requirements and after flowering does not require high soil moisture , it prefers dry weather for ripening .
The water supply of the bean must still be ensured by irrigation of the features cold waters of the River Melfa , Mollarino of the river and their tributaries . To avoid thermal stress should irrigate at night or early in the morning . Particularly important to the first irrigation practiced after germination when the map tends to wilt. Subsequent irrigations are performed with a maturity of 5-8 days.
The crop requires no fertilization , this will benefit the residues of fertilization , very careful , practiced by the crop that precedes it in rotation.
The " Cannellini Atina " has a maturity scale , so the collection will be delayed in time by uprooting the plants are already mature . The collection period is performed at the end of September , beginning of October.
The plants eradicated even by hand, aggregate into bundles that need to be hung under the canopies , open , well-ventilated and in a dry environment until the completion of maturation that occurs in 15-20 days. After this phase, the threshing and melons are finally stored in bags or wrapped . Sorting, this also done manually , is used to remove impurities and seeds stained, only for this operation does not exceed an hourly production rate of 3 kg / h .It is difficult to obtain a yield of more than 15 q.li / ha.
