Changes in Selected Production Parameters and Fatty Acid Composition of Sunflower (Helianthus annuus, l.) in Response to Nitrogen and Phosphorus Applications

Popis výsledku v původním jazyce

The effect of N and P fertilization on the dry matter content, concentration of nutrients (N, P, K, Ca and Mg) and their intake by the plant, production characteristics (achene yields, head diameter, 1000-seed weight, oil content and oil production) andthe content of fatty acids (palmitic, stearic, palmitooleic, oleic, linoleic and linolenic) was evaluated in the one-year pot trial with sunflower (Helianthus annuus, L.). Nitrogen application had a positive effect on dry matter production and increasedN intake by plants as early as the beginning of vegetation (4th true leaf). The effect of P on dry matter production was not markedly evident until the later growth stage (10th true leaf). At the end of the vegetation period the weight of plants of variants fertilised with N only and variants where P was applied evened out. Achene yields, head diameters, 1000-seed weight, oil content and oil production increased statistically significantly after N application. Of all the monitored charac
