Description
  • V jednoletém nádobovém vegetačním pokuse byl sledován vliv N a P hnojení na obsah sušiny, koncentrace živin (N, P, K, Ca a Mg) a jejich odběr rostlinou, výnos nažek, průměr terče, hmotnost tisíce semen, olejnatost, produkce oleje a kvalitu oleje z pohledu zastoupení mastných kyselin (palmitová, stearová, palmitoolejová, olejová, linolová a linolenová) u slunečnice roční (Helianthus annuus, L.). Aplikace dusíku pozitivně ovlivnila produkci sušiny a zvýšila odběr N rostlinou již na počátku vegetace (4. pravý list). Fosfor se na produkci sušiny výrazně projevil až v pozdější fázi růstu (10. pravý list). Na konci vegetace se hmotnost rostlin mezi variantami hnojenými pouze dusíkem a variantami s aplikací fosforu vyrovnala. Výnos nažek, průměr terčů, hmotnost tisíce semen, olejnatost a produkce oleje se statisticky průkazně zvýšily vlivem aplikace N. Zvýšenou zásobou fosforu v půdě byla ze sledovaných charakteristik signifikantně ovlivněna pouze hmotnost tisíce semen. Obsah mastných kyselin se vlivem aplik (cs)
  • 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) and the 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 increased N 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 characteristics the in
