The physical and chemical properties of camelina (Camelina sativa (L.) Crantz) seeds subjected to sulfur fertilization

Abstract

Camelina is an oilseed crop. Seeds may have an application in various industries. Sulfur applied to soil can increase the seed yield. However, there is insufficient information on the optimal dose of sulfur fertilization that provides the best physical and chemical properties of seed. The aim of this study was to determine the physical and chemical properties of camelina seeds subjected to sulfur fertilization at 0 (control), 15, 30 kg S ha-1 applied as potassium sulfate. The content of crude fat of camelina seeds ranged from 346.4 g kg-1 dm (30 kg S ha-1) to 360.9 g kg-1 dm (control plots). The selected shape factors and linear dimensions of camelina seeds were significantly positively affected by sulfur fertilizer applied at 30 kg S ha-1. The results can be used to select the optimal dose of sulfur fertilizer, which has the greatest positive effect on camelina seed properties. Seeds with the best characteristics are desirable for the processing. The optimal dose of sulfur fertilizer is 30 kg S ha-1. It may be useful in practice that the selected linear dimensions and shape factors of seeds were significantly positively affected by sulfur fertilizer applied at 30 kg S ha-1.
