| Description
| - Na cukrovce Beta vulgaris napadené mšicí Aphis fabae a na jarním ječmeni napadeným Rhopalosiphim padi byl sledován vliv přihnojení rostlin sírou (S) v kombinaci s dusíkem na růst rostlin a jejich rezistenci k mšicím. Rostliny byly pěstovány v konstantních podmínkách na těžké půdě z řepařské oblasti, dobře zásobené živinami, s obsahem ve vodě rozpustné S 20 mg/kg suché půdy. Síra a N ve formě dusičnanu amonného a síranu sodného byly aplikovány do půdy před setím. Obě živiny stimulovaly růst cukrovky a ječmene, jejich efekt byl ale výrazně zvýšen, když byly aplikovány současně. Cukrovka reagovala na S mnohem lépe než ječmen. U obou plodin varianty přihnojené samotným N měly nejvyšší počet mšic. Přídavek S k N ve většině případů napadení rostlin snižoval. Nejlepší účinek na rezistenci plodin k mšicím měla kombinace S s nižší dávkou N. Přihnojení způsobilo změny obsahu volných aminokyselin a amidů v nadzemních částech obou plodin, tyto změny ale plně neodpovídaly stupni napadení rostli (cs)
- The effects of sulfur (S) fertilization in combination with nitrogen (N) on plant growth and resistance to aphids were studied in sugar beet (Beta vulgaris) infested with Aphis fabae and summer barley (Hordeum sativum) infested with Rhopalosiphum padi. Plants were grown in constant conditions on a heavy soil from sugar beet growing region, well supplied with nutrients, with water soluble S content 20 mg.kg-1 dry soil. Sulfur and N in the form of ammonium nitrate and sodium sulfate were applied in different combinations into the soil before sowing. In sugar beet and barley both nutrients stimulated plant growth, but their effects were significantly enhanced when applied simultaneously. Sugar beet responded to S much better than barley. In both crops, the variants where only N was applied had the highest number of aphids. Addition of S to N in most cases decreased plant infestation. The best effect on crops resistance to aphids had combinations of S with lower doses of N. The nutrients treatment
