Abstract
This paper presents the methodology and results of experimental studies of the dependence of the flight distance of seeds in the sub-coulter space on the speed of airflow, provides a comparative analysis of theoretical and experimental studies. The experiment results in determination of mathematical expectation of seed flight distance, mean square deviation, coefficient of variation, absolute and relative errors. The resulting function is linear in nature and shows a directly proportional relationship of factors. For the quantitative evaluation of compliance of theoretical and experimental studies, the authors chose the following criteria: correlation coefficient r, Fisher criterion F and Student coefficient t. Calculations results in the following values: r=0.535; tp=1.031; Fp=3.493. Comparative analysis of theoretical and experimental studies shows that dependencies have an average force relationship (r=0.535), the difference between them is not significant (tT ≻ tP ), and the proposed model is adequate (FT ≻ FP ).
