ROLE OF THE PREVIOUS CROP IN THE REDUCTION OF THE PERISHABILITY OF SPRING WHEAT BY ROOT ROTS
The degree of infection on vegetation residues of the previous crop in the autumn after harvesting and in the spring before sowing of spring wheat was determined and studied. As a result, the cultures which could not be affected by root rot (peas, corn, clover, alfalfa), weak-affected (winter rye) and affected (wheat, barley) were allocated. The connection between the population density of soil conidia Bipolaris sorokiniana, the development of root rot and yield was examined.
