Effect of crop management on fatty acid profile in sunflower

Fatty acid composition is the main determinant of oil quality. Genotype (G), environment (E) and interaction (G × E) determine oil fatty acid composition. Some environmental factors are climate, soil structure, and crop management (crop rotation, sowing date, crop density, etc.). This research was c...

Description
Summary:Fatty acid composition is the main determinant of oil quality. Genotype (G), environment (E) and interaction (G × E) determine oil fatty acid composition. Some environmental factors are climate, soil structure, and crop management (crop rotation, sowing date, crop density, etc.). This research was conducted to evaluate changes in the fatty acid composition in sunflower hybrids depending on genotype and different crop densities. Five confectionery hybrids (NS Goliat, NS Slatki, NS Gricko, Vranac, Cepko) and one for birds feeding (NSH-6485) were sown in six crop densities from 20000-70000 plants per hectare (increasing step of 10000) in a randomized complete block design with four replications. Fatty acid composition was determined by gas chromatography using the Konik HRGC 4000 system.
