The objective of the work was to evidence the effects of the species of ground cover in the winter period on the nutraceutical quality of the grains of the soybean cultivars. The experiment was carried out in a randomized complete block experimental design organized in a factorial scheme with five soybean cultivars (50i52 RSF IPRO, 55I57RSF IPRO, DM 57i52 IPRO, BMX Lança 58i60 RSF IPRO, M 5838 IPRO) versus four soil coverings [linseed, white oat, wheat and pasture (ryegrass)], with treatments arranged in four replications, totaling 80 experimental units. In the useful area of each experimental unit, 10 plants were randomly harvested per experimental unit, where crude protein (CP, %), ether stratum (ES, %), mineral material (MM, %), oil (OIL, %), crude fiber (CF, %), palmitic acid (PA, %), stearic acid (SA, %), oleic acid (OA, %), linoleic acid (LA, %), linolenic acid (LNA, %), and percentage of greenish grains (GG, %) were analyzed. Soil coverings influence the nutritional composition of soybean grains, and linseed, white oat, and wheat are responsible for stability and the expression of the percentage of protein and oil in the grains. Based on the WASSBY index, the DM 57i52 genotype presents the best expression ideotype of nutraceutical characters. [ABSTRACT FROM AUTHOR]
