The survey deals with some problems of industralized agriculture development and its conditions. This development was promoted both by economic and biological progress, whereas advances in plant breeding enabled to completely mechanize technology of various crops cultivations claimed to be difficult enough (e.g. maize and sugar beet). It resulted in enormous energetic inputs for agricultural production...
The aim of the paper is to evaluate the effects of five agrotechnical factors on: a) mean root weight of sugar beet plants per plot and within-plot standard deviation of root weight, b) coefficient of determination for root weight of sugar beet plants by three independent variables x₁, x₂ and х₃ and standardised partial regression coefficients for those independent variables. The factors investigated...
