THE EFFECT OF PERLITE USING ON QUANTITATIVE AND QUALITATIVE INDICATOR OF SEED GROWTH
06.00.00 Agricultural sciences
Description
An experiment has been carried out on the effect of germination of seeds with perlite on the improvement of the growth force of rye Vyatka-2. The purpose of the experiment was to study the effect of perlite on the growth force of seeds under the conditions of additional fertilizers and changing the volume water during irrigation. The task of the work was to determinate the growth force of seeds with perlite. The growth force of the seeds was determined after 10 days in sprouted seeds in five samples in glass vessels with three different moisture conditions. It was proved that germination of seeds with perlite increased the seed growth force up to 28% in comparison with seeds grown in sand (a control sample). The result also depended on decreasing of humidity rate up to 30-40%

PROCESS EVALUTION OF SEEDS PRE-SEEDING TREATMENT WITH INFRARED RADIATION
05.20.00 Processes and machines of agroengineering systems
Description
The main subject spotted in this article is a calculation method which helps to depict optimal temperature conditions for seeds stimulation by infrared radiation useful for electromagnetic processing and seed-pelleting with perlit next. The analysis helped to depict that the convenient technical aspects of shortwave infrared radiation is in range 0,76-1,4 mcm. This kind of infrared radiation has the greatest penetrating power into the grain to stimulate. According to the methodology a rapid increase of the temperature of seeds after the critical point reaching during IR treatment leads to the properties deterioration of the of thermolabile materials. The temperature gradient during the IR treatment of seeds has the opposite direction of moisture content and depends on the preliminary humidity of the material. This affects the pre-planting cultivation quality of seeds. To avoid overheating and seeds damage there was a mathematical model of the optimal temperature of the IR radiation calculated. As the result of this method there was obtained the calculation of temperature conditions for IR treatment and heating rate depending on seeds humidity. This calculation method helps to define optimal temperature conditions to avoid harmful influence on seeds due to heating. There was data fitting during this method creation and evaluation which defines the effectiveness and perspective of this elaboration
