Abstract

U ovom diplomskom radu provedena su istraživanja prihrane mikrokapsula s cinkom na agronomska svojstva predivog lana. Pokus je postavljen na Pokušalištu Maksimir Sveučilišta u Zagrebu Agronomskog fakulteta tijekom 2021. godine. Korištena je metoda slučajnog bloknog rasporeda u četiri ponavljanja i pet različitih varijanti prihrane. Posijana je sorta lana Agatha, a varijante su strukturirane na ovaj način: 1. varijanta kontrola bez mikrokapsula, 2. varijanta mikrokapsule s 0,25 mol/L Zn, 3. varijanta mikrokapsule 0,25 mol/L Zn i 1% kitozana, 4. varijanta mikrokapsule 0,5 mol/L Zn i 5. varijanta mikrokapsule 0,5 mol/L Zn i 1% kitozana. Na osnovi provedene analize varijance utvrđena je signifikantna razlika samo za prinos ukupnog vlakna predivog lana kod 2. varijante. Najveći prinos stabljike prije močenja, prinos i postotak ukupnog vlakna, te prinos i postotak dugog vlakna imala je 2. varijanta s 0,25 mol/L Zn.

Abstract (english)

In this master’s thesis, the investigations of top dressing with zinc microcapsules was carried out on the agronomic properties of fiber flax. The experiment was set up at the experimental field Maksimir of the University of Zagreb Faculty of Agriculture, during 2021. 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 with 0.25 mol/L Zn and 1% chitosan; variant 4. microcapsules with 0.5 mol/L Zn; and variant 5. microcapsules with 0.5 mol/L Zn and 1% chitosan. Based on the analysis of variance, a significant difference was determined only for the total fiber yield in the 2. variant. The highest yield before retting, yield and content of total fiber and yield and content of long fiber were achieved in the 2. variant top dressing with 0.25 mol/l Zn.
