RICE CALIBRATION

Rice is one of the strategic food crops which takes up in the world agricultural industry. In Ukraine the rice cultivation traditionally ranks high. In recent years the culture generated interest among scientists and consumers. Breeding of rice put succesfully over, create new sorts with competing ability with the sorts of foreign breeding. While rice researching we were defining a possibility of using CAD machine in presowing treatment with the purpose of an infectioning reduction of the seed material and arising it sowing qualities

Table 1. Sowing and phytosanitary indexes of seeds of rice, separated by machine CAD. Affect index – 29%

We have received the best results on germination ability in the 2nd — 4th fractions. These indexes are quite different comparing with the initial material and the 5th fraction. So an effectivness of calibration according to specific gravity is quite proves it worth. Rice as a culture growing in absolute humidity, and fractioning according to specific gravity gives the opportinuty to receive certified seeds using only the method of separation.
