The procedure of combined electrooptical processing which allows to disclose the reasonable energy and technological conditions of seeds’ treatment and to define the main factors which influence such seeds’ sowing qualities as: germinating power, germinating ability and length of sprouts is used in this article. Besides, the procedure allows conducting the research of efficiency evaluation of some rational parameters and conditions of treatment which influence their yield characteristics in field conditions. The research task was to obtain the data about the number of spring barley called “Ratnik” shoots and their productivity depending on the number of working volume converter’s lamps (1-6) and on the protectant’ norm percent (1-100). The experiments have been carried out and the data have been obtained for this purpose and the processing of these data has given the regression equation of the second order writing the process with the volumetric graphical interpretation. The rational parameter space of presowing treatment providing maximal germination and crop capacity of barley “Warrior” has been obtained on basis of the diagrams’ analysis. As the growth of germinating ability and crop capacity is observed when the number of working lamps is increased the double spreading at 6 working lamps should be recommended. The concentration of the protectant practically ceases to influent the crop capacity. According to the results of the research there has been drawn a conclusion that preliminary seeds treatment, for the purpose of plant diseases preventing, restrains the germination processes at the initial level. It happens in connection with conditions deterioration of moisture access to seeds which are covered with protectant film. Further processing of treated seeds by optical radiation promotes the growth of germinating ability and length of sprouts compensating negative effect of treatment
