The harvest time of fibre flax is influenced by climatic conditions, varieties, stages of maturity and the crop's final use. In addition, the time of harvesting of fibre flax affects the quality of the fibres. Fibre flax can be harvested in few stages of maturity. So, this paper presents the influence of three stages of maturity (green, yellow and full ripening) on the agronomic traits (stem yield, stem yield after retting, total fibre yield, share of total fibre, long fibre yield, share of long fibre) of five fibre flax varieties. Varieties trials with fibre flax were set up in two years (2010-2011) and in two locations: at the experimental fields of the Faculty of Agriculture in Zagreb on eutric cambisol and of the College of Agriculture at Križevci on pseudogley on level terrain. The trials were carried out according to the randomized complete block design (RCBD) with four replications. According to the results of the two-years research into the agronomic traits of fibre flax, significant differences were established among the varieties and among the stages of maturity under study. The varieties Agatha, Viola and Electra recorded higher values of investigated traits. All varieties achieved higher values of investigated traits at Križevci (production on heavier soil in which some of winter moisture remained available in spring months). The highest values of investigated traits were recorded when the fibre flax were harvested in the green ripening.
U radu se iznose rezultati postignutog prinosa i sastavnica prinosa sjemena (broj biljaka po m2, broj tobolaca po biljci, broj sjemenki u tobolcu, masa 1000 sjemenki) pet inozemnih sorata predivog lana gnojenih različitim količinama dušika (0, 30, 60 i 90 kg ha-1) primijenjenih u različito vrijeme. Pokusi s predivim lanom provedeni su tijekom tri godine (2008.-2010.) u Zagrebu na eutrično smeđem antropogeniziranom tlu i u Križevcima na pseudogleju obronačnom prema metodi slučajnog bloknog rasporeda u četiri ponavljanja. Na osnovi trogodišnjih istraživanja prinosa i sastavnica prinosa sjemena predivog lana utvrđeno je da postoje signifikantne razlike između istraživanih sorata i između primijenjenih količina dušika. Sorte Viking, Venica i Electra ostvarile su veće vrijednosti istraživanih svojstava. Prema dobivenim rezultatima u gnojidbi predivog lana nije potrebno dodavati više od 30 kg ha-1 dušika. Ključne riječi: predivi lan, sorte, gnojidba dušikom, prinos sjemena, sastavnice prinosa sjemena
This paper presents a three-year study of the influence of different amounts of nitrogen on the properties of flax plants and fibres. At the same time, the acclimatization ability of five different cultivars of fibre flax was estimated through the valorisation of their morphological (technical stem length, stem thickness) and physical-mechanical properties of the fibres (length, fineness, tenacity). Cultivar trials with fibre flax were set up across three years (2008–2010) at the following locations: the experimental fields of the Faculty of Agriculture in Zagreb on anthropogenized Eutric Cambisol and the College of Agriculture at Križevci on pseudogley on level terrain. The selected cultivars were fertilized without and with different nitrogen rates (30, 60 and 90 kg/ha) in different time. The trials were carried out according to the RCBD in four replications. According to the results of the three-year study of flax and fibres, significant differences were established among the cultivars and among the added nitrogen rates under study. Based on the results of the morphological and textile-technological properties of flax, the cultivars Viola and Agatha achieved higher values at the location of Križevci, where it was not necessary to add more than 30 kg N/ha.
The amount and quality of fibres depend on a whole range of factors, the most important being variety, agroecological conditions, agrotechnics and the degree of fibre flax plant maturity, the purpose for which flax is grown, retting and processing. The retting of fibre flax is the most complex stage in the processing of flax into fibre. The aim of this study was to gain knowledge about the acclimatization ability of foreign varieties that can potentially be adapted to climatic in Republic Croatia. Therefore, this paper presents the results of achieved agronomic traits (dry stem yield, dry stem after retting, total fibre yield, long fibre yield, share of total fibre and share of long fibre) of five foreign varieties of fibre flax. The selected varieties were retted in very soft, medium hard and hard water. Variety trials with fibre flax were set up over three years (2012–2014) at two locations (Zagreb) on anthropogenized eutric cambisol and (Križevci) on pseudogley on level terrain. The trials were carried out according to the RCBD in four replications. According to the results of the three-year research into the agronomic traits of fibre flax, significant differences were identified among the varieties studied. The varieties Agatha, Viola and Electra recorded the highest values of studied traits. Statistically significant differences were only recorded among different water hardness for long fibre yield in 2012 and share of total fibre in 2013 in Zagreb. The highest yields and share of fibres were recorded when the fibre flax was retted in very soft water.
