Interdependence of Traits in Early-Maturing Genotypes of Cabbage (Brassica oleracea var. capitata L.)
(International Society for Horticultural Science, 2012)
In this paper we studied the variability and correlation of agronomic traits in early maturity cabbages. The study included early spring cabbages (planted in early spring, harvested in early summer). Using coefficients of ...
Screening perennial Helianthus species for powdery mildew
(Paris : International Sunflower Association, 2012)
Powdery mildew (Erysiphe cichoracearum) has been reported as a potential constraint for sunflower growing in regions with warm climate. Severity of disease varies depending on the sunflower genotype. Aim of this research ...
Procena merne neizvesnosti i validacija metode određivanja acetamiprida i 6-hlornikotinske kiseline u uzorcima trešanja
(Društvo za zaštitu bilja Srbije 11080 Beograd 80, Nemanjina 6; p.fah 123, 2012)
Pojava ostataka pesticida u voću i povrću moguća je i pored poštovanja principa dobre poljoprivredne prakse. Identifikacija prisutnih pesticida i određivanje njihovih količina u ovim matriksima zahteva primenu metoda visoke ...
Uticaj olova i hroma na mikrobiološku aktivnost u zemljištu pod usevom Trifolium pratense L. / Effect of lead and chromium on microbial activity of soil under Trifolium pratense L.
(Abstract Proceedings, International Conference Submediterranean Agriculture-ICSA 2012, Mostar, 22-24 November 2012, 2012)
Mikroorganizmi su indikatori plodnosti zemljišta, ali i procesa njegove degradacije. Povećane količine teških metala u zemljištu ili u zemljišnom rastvoru mogu imati toksičan efekat na rast i razviće svih sistematskih i ...
Trace analysis of sulfonylurea herbicides in soil samples using solid phase extraction and liquid chromatography with photodiodes detection
(Beograd : Društvo za zaštitu bilja Srbije, 2012)
Sulfonylurea herbicides are new class of herbicides that function by inhibiting the action of acetolactate synthase or acetohydroxyacid synthase, key enzymes in the biosynthesis of amino acids in plants. These herbicide ...
Determination of chlorpyrifos residues in water
(Nova Gorica : University of Nova Gorica, 2012)
Chlorpyrifos (0,O-dietyl O-(3,4,5-trichloro-2-pyridy!) phosphorothioate) is the one of
the most widely used insecticides in the world and it is detected more frequently in
surface and groundwaters than any other ...
Microwave assisted solvent extraction and reversed phase liquid chromatography with diode array detection for screening sulfonylurea herbicides in soil samples
(Beograd : Društvo za zaštitu bilja Srbije, 2012)
Sulfonylurea compounds are characterized by high herbicidal activity allowing
low-dose rates for the control of many grasses and broadleaf weeds in the
agriculture of crops. This feature means, however, that under ...
