“…In our case, in contrast to Couture et al (2002), we found that Belinka did not have any additional specific emergence problem, as in two of the three sowings it actually had superior emergence to Ariane.…”

Triennial field trials were carried out at Viterbo, central Italy, to investigate the influence of the sowing time, nitrogen fertilization and harvest dates of the two fibre flax (Linum usitatissimum L.) varieties Belinka and Ariane. Our results showed that warm and dry weather conditions, prevailing from late spring onwards, caused excessive shortening of the growing cycle of spring crops, with negative consequences for seed and fibre yield and quality. However, autumn sowings gave interesting results. Stem dry weight ranged between 5.6 and 6.7 t ha−1 for autumn sowings and between 1.9 and 4.1 t ha−1 for spring sowings. In autumn sowings, plant height and seed yields were also increased. Seed germinability was good even for early harvest dates. Stem dry weight remained constant at harvest dates following yellow‐green ripening, indicating that biomass was no longer allocated to the stems after that phase.

“…Both cultivars had upright and in the case of the 8.5 cm row spacing straight unbranced stems, only Laura cultivar formed branches, at medium spacing it formed averagely from 0.34 to 1 branch per one stem, but the largest row spacing influenced the formation of one to two branches per stem ( Table 2). Branching of the stem is genetically predetermined (Couture et al, 2002), which was confirmed also by our research, where the RBK cultivar remained branchless also at the biggest row spacing 34 cm.…”

“…Regarding certain morphological and economicaly significant characteristics, such as absolute mass, plant height and linseed yield (Couture et al, 2002), the domestic cultivar RBK has more characteristics of the seed type flax, but its nonbranched stem is the typical characteristic of the fibre producing flax cultivars. Considering also its fibre yield, it is comparable to the Dutch cultivar Laura, therefore it can be used for fibre production and production of high quality linen, products from the Raztresen farm also confirm its importance for fibre production.…”

In the period [2003][2004][2005][2006] we have performed block trials with two flax (Linum usitatissimum) cultivars: RBK cultivar (domestic flax population from Raztresen farm in Bela Krajina) and Laura cultivar (fibre-type-flax from the Common Catalogue of EU). The trial was carried out at the Experimental Field at the Biotechnical Faculty of Ljubljana (Slovenia). The two cultivars were sown in the first decade of April with manual sowing machine to the row spacing of 8.5 cm, 17 cm and 34 cm. Crop care was traditional. The plants were plucked at the end of the yellow maturity (the last decade of July). There was no significant difference between the average yields of stems produced at the row spacing of 8.5 cm (1.92 t/ha) and 17 cm (1.99 t/ha), but significantly the lowest yield was reached at the row spacing of 34 cm (1.52 t/ha). In the period of 4 years the average yield of stems that was reached by the RBK cultivar was 1.83 t/ha, and the one reached by the Laura cultivar was unsignificantly lower (1.79 t/ha). Compared to the average yield of the flaxseed from both cultivars produced at the row spacing of 8.5 cm (1.34 t/ha) and 34 cm (1.01 t/ha), the average yield of the seeds obtained from the 17 cm row spacing was significantly the highest (1.52 t/ha); for 0.11 t seed/ha the RBK cultivar (1.35 t/ha) was significntly more productive than the Laura cultivar. The influence of growing conditions to the yield of stems and seed was most favourable in the year of the drought (2003), when -with the cultivar RBK and at the row spacing of 17 cm -we produced significantly the highest quantity of stems (2.64 t/ha) and seeds (1.93 t/ha). We discovered that the unbranched stem of the RBK cultivar corresponds to the fibre-type-flax, the hight of plants (50 to 60 cm), absolute mass (6.3 to 6.8 g) and the yield of the seed (above 1 t/ha) show good biological capability for the seed production. Production and processing of flax should not remain just an attractive cultural and historical presentation of this activity at some turist farms in Bela Krajina (JV of Slovenia); it should also present a challenge to young farmers to find the place for this crop in organic production of food and other raw materials with the use of mechanisation and modern technological procedures. The production and processing of flax presents the possibility for increased biotic diversity of the cultural landscape and revitalization of rural areas.

“…Early and uniform establishment is crucial to the success of fibre flax crops. Flax is often seeded at rates to attain final densities of 2000 plants m )2 (Sultana 1983, Robert 1995, Stephens 1997, Couture et al 2002, so even a partial delay in emergence can result in a highly non-uniform stand, as plants which emerge late are at a competitive disadvantage (Fowler 1984). Uniformity is a desirable characteristic in fibre flax destined for linen production, as the length of fibres will influence the price a producer obtains for the crop (Ulrich and Laugier 1995).…”

The feasibility of producing fibre flax in minimum tillage or zero tillage (ZT) systems was investigated. The results were variable between the sites, which differed in soil type and previous cropping history. Tillage regime had no impact on fibre flax phenological development including number of days to emergence, days to flowering and days to harvest at either site. However, tillage regime had a significant effect on mean stem diameter, dry matter content and plant height at all three sampling dates at the sandy loam site, and a significant effect on mid-season plant height at the clay site. At the sandy loam site, ZT plots had the highest populations of plants with the finest stem diameters, the lowest branching ratios, but the shortest plants by the end of the season. Overall, plant densities were greater, stem diameters thinner, and biomass production higher in the heavier soil of the clay site. These results indicate that under the growing conditions present in 1998, fibre flax can successfully be grown in minimum or ZT systems on different soil types in Eastern Canada. Moreover, the growth of fibre flax in these systems does not compromise the proportion of tall plants having thin stems and minimal branching, a critical quality parameter for fibre flax production.
