The effect of organic fertilizers on the productivity of winter rapeseed in the conditions of the Kaliningrad region

Abstract

Winter rapeseed is a valuable oilseed and fodder crop. In the conditions of the Kaliningrad region, the cultivation of winter rapeseed is economically profitable, it is one of the leading crops; it occupies from 15 to 30% in the crop rotation. Conducted research in the Pravdinsky municipal district, on the fields of Pravdinskoye pig breeding JSC in 2018-2020. Winter rapeseed is demanding of nutrients throughout the growing season. Livestock farming is actively developing in the Kaliningrad region; therefore, the study into the application of organic fertilizers to increase crop productivity is of current relevance. Swine manure, which is primarily a nitrogen-potassium fertilizer, is a valuable quick-acting fertilizer. Liquid organic fertilizers are applied during the main fertilizing procedure minimizing odor and increasing application efficiency. The aim of the study was to investigate the effect of pig manure fraction on the productivity of winter rapeseed. All research results confirmed statistical data. Based on the results, conclusions were drawn.
