Influence of microcapsules with zinc supplement on the agronomic and morphological properties of fiber flax

Istraživanje ovog rada provedeno je kako bi utvrdili utjecaj prihrane mikrokapsulama s cinkom na agronomska i morfološka svojstva predivog lana. Pokus je postavljen na Pokušalištu Agronomskog fakulteta Sveučilišta u Zagrebu, lokacija Maksimir, tijekom 2020. godine. Korištena je metoda slučajnog bloknog rasporeda u četiri ponavljanja i pet različitih varijanti. Posijana je sorta lana Agatha, a varijante su strukturirane na ovaj način: varijanta 1- kontrola bez dodatka mikrokapsula, varijanta 2- mikrokaspule s 0,25 mol/L Zn, varijanta 3- mikrokaspule 0,25 mol/L Zn i 1% kitozana, varijanta 4- mikrokapsule 0,5 mol/L Zn i varijanta 5- mikrokapsule 0,5 mol/L Zn i 1% kitozana. Na osnovi provedene analize varijance nisu utvrđene signifikantne razlike između istraživanih svojstava varijanata. Najveći prinos stabljike prije i nakon močenja te najveći prinos ukupnog i dugog vlakna ostvaren je kod varijante 2. prihranjene s 0,25 mol/l Zn. The research of this work was carried out in order to determine the influence of supplementation with microcapsules with zinc on the agronomic and morphological properties of fiber flax. The experiment was set up at the experimental field of the Faculty of Agriculture of the University of Zagreb, location Maksimir, during 2020. The experiment was set up according to the RCBD in four replications and five different variants. The fiber flax variety Agatha was sown, and the variants were structured in this way: variant 1- control without the addition of microcapsules, variant 2- microcapsules with 0.25 mol/L Zn, variant 3- microcapsules 0.25 mol/L Zn and 1% chitosan, variant 4- microcapsules 0.5 mol/l Zn and variant 5- microcapsules 0.5 mol/L Zn and 1% chitosan. Based on the analysis of variance, no significant differences were found between the investigated properties. The highest stem yield before and after reting and the highest yield of total and long fiber was achieved in the variant 2 supplemented with 0.25 mol/l Zn.
