LABORATORY INCINERATION OF MICROWAVE SEEDS OF BARLEY
The study is devoted to the assessment of the de-gree of trauma of barley seeds by working bodies of agricultural machines. Since the high stability of crops is based on high quality seeds. However, in the process of mechanized harvesting and post-harvest processing, mechanical damage to the seed material is observed. In particular, the degree of damage to the grain depends on the type of grain, its state, physical and mechanical properties, and also the type of technological operation performed. So along with the ways of visual control of the amount of mechanical damage, it’s suggested to check their germination using germinator. The purpose of the study was to determine the germination of grain material that had undergone mechanized processing in laboratory conditions using the aerosol plant “Rosinka”. Basing on experimental studies carried out, the effect of trauma on the germination of barley seeds is deter-mined depending on its physical and-mechanical prop-erties and the state of grain material. Experimental de-pendences are given, according to which the extreme is indicated, i.e. maximum germination value in the per-missible range of humidity variation for different values of the number of grain passes through the machine. Basing on the results of conducted studies, it was re-vealed that with the increase in the number of seed passes through the machine, at the same humidity, their germination decreases; grains of barley, which have lost shell, have a germination capacity lower than grains not injured on average by 20 %; germinated traumatized grains are characterized by weak sprouts. Proposed method of grain assessment with using aeronautical installation can be considered prospective and its im-plementation will improve the efficiency of analyzing seed lots for sowing quality.
