Development of a methodology for allocating seed production zones based on established types of seed yield and soil-climatic zoning

Abstract

The method of allocation of zones of seed production of agricultural plants depending on soil and climatic factors is developed on the basis of the established four types of seed yield: type I - high yield, high seed quality; type II - high yield, low seed quality; type III - low yield, high seed quality; IV - low yield, low seed quality. Data on crop types were plotted on a contour map of the studied administrative subject (region, territory, republic) with the designated boundaries of districts and soil-climatic zones, as a result, 4 possible zones of seed production were identified: 1- the zone of optimal seed production, in which the seed farms form the I type of crop; 2 - the zone of risky seed production (II type of crop); 3 - the zone of permissible seed production (III type of crop); 4 - the zone of unacceptable seed production (IV type of crop). The network of seed farms should be organized primarily in the areas of optimal seed production. When organizing the production of seed material in the zones of permissible seed production, it is necessary to increase the yield by improving agricultural technologies. In the zones of risky (II type of crop) and unacceptable (IV type of crop) seed production, it is not advisable to produce seed material.
