Uticaj različitih organskih đubriva na sadržaj ulja i oleinske kiseline kod konzumnog suncokreta

Abstract

U Srbiji se visokoproteinski konzumni hibridi suncokreta proizvode u manjem obimu u konvencionalnim i organskim uslovima proizvodnje, uz stalno povećanje površina pod organskom proizvodnjom. Krupno seme se koristi za veći broj prirodnih zdravih proizvoda i za direktnu potrošnju, dok se od manjih frakcija semena proizvodi hladno presovano suncokretovo ulje. Analizirao se uticaj organskog đubriva: tretmanom Guanito (T1) 0,5 t ha-1 u fazi BBCH 01, dok su tretmani sa Trainerom (T2) 3 l ha-1 i Natur Plasmom (T3) 5 l ha-1 izvedeni u fazi BBCH 36 na sadržaj oleinske kiseline i ulja u semenu NS konzumnih hibrida suncokreta i upoređeni su sa netretiranom kontrolom (C) u organskoj proizvodnji i sa mešanim NPK đubrivom (50:50:50) tretmanom kao kontrolom (K) u konvencionalnoj proizvodnji. Organska đubriva nisu uticala na povećanje sadržaja oleinske kiseline i ulja u poređenju sa kontrolom. Hibridi su se statistički značajno razlikovali po sadržaju oleinske kiseline i ulja u semenu. Nije se uočila interakcija između tretmana i sadržaja oleinske kiseline i ulja, niti bilo kakva statistički značajna interakcija između tretmana i hibrida. NS konzumni hibridi se mogu uspešno gajiti u konvencionalnim i organskim uslovima proizvodnje što potvrđuju rezultati istraživanja, između sadržaja oleinske kiseline i ulja nije bilo statistički značajnih razlika u kontroli u organskim i konvencionalnim uslovima gajenja.

In Serbia, high protein confectionery sunflower hybrids are produced on a smaller scale both in conventional and organic production systems, with constant increase of area under organic production. Large seeds are used in a number of natural health products, as well as for direct consumption, while smaller seed fractions are used in the production of cold-pressed sunflower seed oil. Analysed the effect of organic fertilizer Guanito (T1), 0.5 t ha-1, was performed at the stage BBCH 01, while treatments with Trainer (T2), 3 l ha-1 and Natur Plasma (T3), 5 l ha-1, were carried out at the stage BBCH 36. on seed oleic acid and oil content of NS confectionary sunflower hybrids and compare them with untreated control (C) in organic production and with mixed NPK fertilizer (50:50:50) treatment as control (K) in conventional production. All organic fertilizers hadnot positive effect on oleic acid and oil content compared to control. Organic fertilizers did not affect the increase in oleic acid and oil content compared to the control. The hybrids differed statistically significantly of seed oleic acid and oil content. No interaction was observed between treatment and oleic acid and oil content, nor any statistically significant interaction between treatment and hybrid. NS confectionery hybrids can be successfully grown in conventional and organic production conditions, which is confirmed by the research results, there were no statistically significant differences between oleic acid and oil contentin in the control in organic and conventional growing conditions.
