THE SIMULATION OF SPRING WHEAT GRAIN YIELD UNDER THE CONDITIONS OF TEMPERATE ARID FOREST-OUTLIER STEPPE OF THE ALTAI REGION
The use of information-logical analysis in our research enabled to identify the effect of each factor, evaluate the strength of relationship (the coefficient of information transfer efficiency) and the efficiency of information transfer, and determine the most likely yield states depending on the state of the studied factors. The conducted research revealed the direct influence of soil-agrochemical factors on the yield of spring wheat grain. The agro-technical conditions had an indirect impact on the grain yield. Information and logical analysis revealed the efficiency of each factor using the coefficient of the communication channel efficiency on spring wheat yield and to construct information-logical expression where the studied factors were distributed in order of decreasing importance regarding spring wheat grain yield and the factors were associated by a non-linear function (x). The obtained information-logical model of yield allows planning the grain yield depending on the prevailing weather conditions of the growing season and the state of soil mobile nutrients before sowing against the background of different basic tillage techniques and application of green manure with the forecast power up to 90%.
