Abstract

Cilj istraživanja bio je utvrditi utjecaj starijeg (Rex i Lord) i novijeg sortimenta (Barun i Panonac) ječma na fizikalna svojstva zrna i biomase ječma za potrebe skladištenja. Istraživanje je provedeno na površinama Poljoprivrednog instituta u Osijeku. Uzorkovanje biomase bilo je provedeno na 1m² u tri ponavljanja za svaku sortu. Istraživanjem je obuhvaćeno (I) brojanje stabljika na 1 m², (II) mjerenje duljine stabljike, klasa i dimenzije zrna, (III) vaganja mase (klasa, slame, zrna, pljeve, masa 1000 zrna), (IV) mjerenje volumena (V)izračun sferičnosti te (VI) određivanje sadržaja vlage u zrnu i biomasi. U rezultatima je prikazano kako novije sorte ječma u prosjeku imaju više biljaka na m² za 40.59 %. Novije sorte imaju veću prosječnu masu klasa, slame i zrna, također imaju veći postotak sferičnosti. Novije sorte imaju nešto veći postotak sferičnosti. U temeljnim parametrima kao što su masa slame i masa zrna vidljivo je kako je noviji sortiment ostvaruje veće prinose na m². Ovo istraživanje financirano je iz Europskog fonda za regionalni razvoj, unutar programa Konkurentnost i Kohezija 2014. - 2020., u okviru projekta br. KK.05.1.1.02.0016, “Proizvodnja hrane, biokompozita i biogoriva iz žitarica u kružnom biogospodarstvu”.

Abstract (english)

The aim of the study was to determine the influence of older (Rex and Lord) and newer assortment (Barun and Panonac) of barley on the physical properties of grain and barley biomass for storage purposes. The research was conducted on the surfaces of the Agricultural Institute in Osijek. Biomass sampling was performed at 1m² in three replicates for each variety. The research included (I) counting of stems per 1 m², (II) measurement of stem length, class and grain size, (III) weight weighing (class, straw, grains, chaff, weight of 1000 grains), (IV) volume measurement ) calculation of sphericity and (VI) determination of moisture content in grain and biomass. The results show that newer barley varieties have on average more plants per m² by 40.59%. Newer varieties have a higher average mass of ears, straw and grain, they also have a higher percentage of sphericity. Newer varieties have a slightly higher percentage of sphericity. In the basic parameters such as straw mass and grain mass, it can be seen that the newer assortment achieves higher yields per m². This research was funded by the European Regional Development Fund, under the Operational programme competitiveness and cohesion 2014-2020, project no. KK.05.1.1.02.0016, “Production of food, biocomposites and biofuels from cereals in a circular bioeconomy”.
