The indicator "falling number" determines the presence of starch as its amount decreases during the grain germination process. Wheat germinates at a moisture content of 50%–70% in the presence of drip moisture and positive temperature values above 20C. The research work was carried out in two directions: - a survey of granaries was conducted to estimate their compliance with regulatory requirements and rules; - the quality indicators of stored grain were determined. During the survey, the following stages were carried out: - a visual inspection of granaries No.1 and No.18 was carried out to estimate tightness of containers; - there were carried out measurements of the aerodynamic parameters of the air used for grain active ventilation; - there were analyzed the registration logs of laboratory tests of average daily samples during receiving and delivering wheat grain of the 3 and 4 classes; - the data on grain thermometry in silo No.1 and No.18 were studied during storage period in September; - grain samples were taken to determine quality parameters. The selected samples were analyzed according to the following parameters: falling number (c) and other indicators indirectly related to it: humidity, grain impurity (incl. germinated grains), weed impurity, germination energy and germination rate.
