Influence of nutrition optimization on the main indicators of quality of false flax seeds for cultivation in the south of Ukraine

Abstract

This article highlights the importance of low-investigated and insufficiently widespread oilseed crop of false flax, which can become an alternative to sunflower and other oilseeds. The false flax is unpretentious to growing conditions, it responds well to the optimization of nutrition, italso significantly increases the yield of seeds. Researches were carried out during 2014-2016 on southern Chernozem in the Educational-scientific-practical center of Mykolaiv National Agrarian University with the crop of false flax (variety Stepovyi 1). The optimization of plant nutritionwas investigated by using modern growth-regulating drugs on the background of N15P15K15, that is, on the principles of resource conservation. The influence of nutrition on the main indicators of seed quality was determined.It was determined that depending on thenutrition background not only the level of yield changed but also the quality of seeds. Thus, the protein content considerably increased as well as the conditional harvest per unit of area; the fat content, on the contrary, reducedwith improved nutrition, but in the fatty-acid composition of the oilthe content of the most valuable linoleic acid increased without increasing the amount of erucic acid. According to the research the introduction of false flax crop into production can partially replace the area under the sunflower since it is not inferior to thesunflower on the main criteria of the oil quality as well as on the indicators of its economic efficiency. Keywords: false flax, biopreparations, nutrition optimization, seed quality, fatty- acid composition of oil, fat and protein content.
