Abstract

In this paper, the principal component method is used to process and analyze the main parameters of spring wheat yield formation. The productivity of spring wheat crops is the result of a complex interaction of a variety of factors. Possession of information on inter-factor relationships will allow you to purposefully control the process, influencing one or another factor. Therefore, the task of obtaining information about the structure of the relationship of influencing factors on the yield of spring wheat is relevant. We studied the observation data for spring wheat yields and ten independent factors influencing it for 32 years: productive moisture on the day of sowing, air humidity, precipitation, mass fraction of gluten, mass of 1000 grains, grain weight per spike, length of straw, dose of phosphorus dose of potassium, dose of nitrogen. The main components are constructed in the form of linear combinations of influencing factors. The dispersion fraction of the first main component (GK1) was 39.77%, the second component (GK2) - 20.86%, GK3 - 12.93%, GK4 - 8.79%, GK5 - 6.26%, GK6 - 5, 56%, GK7 - 3.05%, GK8 - 1.78%, GK9 - 0.89%, GK10 - 0.1%. The first three main components explain 73.56% of the variance in total; therefore, a ten-dimensional data array can be analyzed in three-dimensional space. The coordinates of the samples of initial information on the yield of spring wheat in the space of the main components are determined. A visual study of the structure underlying the data was carried out.
