The use of ground-based spectrophotometric measurements to identify the effect of basic tillage methods on the process of growth of above-ground phytomass of spring wheat in grain-crop rotation

The purpose of the researches was to establish the possibility of using spectrophotometric measurements of high spectral resolution for the identification of the dynamics of increasing green material of spring wheat placed after corn, and the formation of the basis of reference characteristics of spectral reflection for the interpretation of satellite data. The research problems were to study the dynamics of the increase of aboveground phytomass of spring wheat on the development phases during vegetative period; to determine the size of aboveground phytomass of spring wheat in crude state; to establish the ranges of reflection of crops of spring wheat during vegetative period on the development phases. The scheme of five-field corn tillage crop rotation developed in time and space included the following cultures: sidereal bare fallow - spring wheat - barley - corn - spring wheat. The frequency in the experiment was quadruple. The arrangement of allotments was two-story, systematic...
