Yield and Yield Criteria of Flax Fiber (Linum usititassimum L.) as Influenced by Different Plant Densities

Abstract

Flax (Linum usitatissimum L.) is mostly grown in temperate climate conditions. The rising demand for natural fibres other than cotton has re-introduced flax cultivation in to the agenda. This situation has necessitated the acceleration of flax production research in Turkey. The purpose of this research is to discover the best seeding density for flax fibre cultivation. The trials were carried out with the Rolin flax variety at the coordinates 41°21′53″ N and 36°11′17″ E, during the winter seasons of 2018–2019 and 2019–2020, at densities of 500, 750, 1000, 1250, 1500, 1750, and 2000 plant m−2, by using a random block design. According to the results obtained from analysis of variance, where all these charectors examined viz, years, densities, year and density interaction were found statistically significant (p < 0.01). The highest straw, fiber and seed yields per decare were measured at 2000 plant m−2 density, while as the lowest values were determined at 500 plant m−2 density. However In the interaction of year and density, the highest plant height and technical length were measured in the first year at 1750 plant m−2 density at 102.7 cm and 80.2 cm, respectively. Similarly the highest straw yield (764 kg da−1), fiber yield (198.6 kg da−1) and seed yield (133.9 kg da−1) were measured in the first year at 2000 plant m−2 density. Adequate rainfall during the rapid development stage of winter flax in April-May boosted plant height, technical length, straw, seed, and fibre yield. Although the yields were low during the second year, which was dry. While the positive significant correlation (**; p < 0.01) was found between plant density and plant height (r = 0.907 **), straw yield per decare (r = 0.981 **), seed yield per decare (r = 0.973 **), fiber yield per decare (0.978 **), technical length (r = 0.828; * p < 0.05), negative significant correlation (p < 0.01) was found between plant density and the number of secondary branches (r = −0.955 **), stem diameter (−0.955 **) and plant seed weight (r = −0.923 **). According to the data recorded in two-years. It was observed that for high straw, fiber and seed yield, 2000 plant m−2 density was appropriate for cultivating flax fiber during the winter growing period in mild climate conditions.

Phytoremediation Potential of Flax Grown on Multimetal Contaminated Soils: A Field Experiment

“…[23], in a pot experiment conducted with three different levels of Cd, Ni, Pb, and Sb in three flax cultivars, concluded that as the dose of the metal and antimony increased, the growth characteristics of the varieties decreased. The mean values of the height recorded in our study align with those reported in other field non-polluted experimental studies, resulting in similar average height values for flaxseed [57,59,69].

Phytoextraction Potential of Flax Grown on Multimetal Contaminated Soils: A Field Experiment

“…[6], in pot experiment that conducted with three different level of cadmium, nickel, lead and antimony in three flax cultivars, concluded that as the dose of the metal and antimony increased, the growth characteristics of the varieties decreased. The mean values of the height recorded in our study align with those reported in other field non-polluted experimental studies, resulting similar average height values for flaxseed [25,27,37]. [25] highlighted the aspect of the growing cycle duration, reporting taller linseed plants (62.9 cm) during autumn sowings compared to spring sowings (55.5 cm) in a semi-arid Mediterranean environment.…”

“…Previous researches underline the complex interaction of factors that impact flax development, such as residual soil nitrogen, soil type, flax cultivar, climate and moisture conditions, and growing cycle duration [10,14,[22][23][24][25][26]. Furthermore, the key roles of plant density, climatic conditions, and nitrogen levels in shaping stem branching in flaxseed have been emphasized in various studies [25][26][27][28][29][30]. Understanding the importance of these factors is crucial when evaluating flax branching patterns, as they significantly affect plant architecture and yield.…”

Effect of Weeds and Seeding Rate on Some Growth Characteristics and Oil Content of Three Cultivars of Flax

“…The reason for this decrease may be due to the increased competition among plants for light and nutrients, resulting from an increased number of plants per unit area. This result agrees with the findings of [17,18], who reported a significant decrease in stem diameter of flax with an increase in seeding rate. Furthermore, the results show that variety Sakha 6 achieved the highest mean stem diameter of 2.56 mm, which was not significantly different from variety Sakha 4 but was significantly different from the local variety, which had the lowest mean stem diameter of 2.40 mm.…”
