Features of post-harvest processing and storage of seed purpose grain

With intensive respiration of seeds with increased moisture, carbon dioxide accumulates in the embankment, and the process of anaerobic respiration is widely developed in the seed cells. The products released at the same time, and especially ethyl alcohol, have a detrimental effect on the cells of the embryo, and the seeds quickly lose their germination. Due to the low respiration rate, dried seeds can be stored for a long time even in a mound of greater height, but the seeds do not lose their germination. The studies were carried out in the conditions of ZAO NP "Chegem" and at the department "Technology of production and processing of agricultural products" of the Kabardino-Balkarian State Agrarian University in 2019-2020. The objects of research were the seeds of agricultural crops. It is advisable to store dry seeds with a moisture content of 14% in a chilled state, i.e. at a temperature of no more than 100C. With the full passage of post-harvest ripening, cooling is carried out immediately after the seeds have entered storage. If it is necessary to shorten the post-harvest ripening process, in this case, it is recommended to carry out active ventilation with slightly warmer air before cooling. It has been established that in order to preserve the quality of seeds during storage, it is necessary to systematically monitor the temperature and relative humidity of the outside air, the possible appearance of pests and changes in organoleptic parameters. The moisture content of stored agricultural seeds must be monitored at least twice a month, as well as after each movement and processing of the grain mass. To accelerate the passage of the post-harvest ripening period when ventilating seed grain in the autumn period, one should strive to reduce the moisture content of the seeds as much as possible in warm weather, supplying a large amount of air to the embankment.
