Sources and rates of nitrogen in the cultivation of flax

Abstract

This study aimed to evaluate the potential development of golden flaxseed (Linum usitatissimum L.) under the influence of the application of sources and rates of nitrogen. The experiment was conducted in the field Unioeste, Campus Cascavel, State of Paraná, using the factorial design (2×5) randomized, two nitrogen sources (urea and ammonium sulphate) and five rates of nitrogen (0, 50 , 100, 150 and 200 kg ha-1). We evaluated the following characteristics: plant height, fresh (FWP) and dry weight (DWP) of plants, number of stems, number of capsules (NC), fresh and dry weight of capsules (FWC; DWC), 100grain weight and yield (kg ha-1). The urea as nitrogen source had a positive influence on the productivity of flax, which was only influenced depending on the nitrogen source. Nitrogen rates influenced some production components, but not the crop.

Effect of Nitrogen Fertilizer on some Flax Varieties under Two different Location Conditions

“…and straw yield per plant, hence straw yield per feddan was highest. These results are in harmony with those of El-Gazzar andKineber (2002),El-Nagdy et al (2010),Geovan et al (2013),Dervisevic et al (2014) andEl-Borhamy (2016). Data recorded in Tables 3-13 show clearly that flax varieties were significantly differed in both 2016/2017 and 2017/6018seasons .…”

“…El-Nagdy et al (2010) reported that 45 kg N/fed have highest seed and straw yields. Geovan et al (2013) reported that nitrogen rates influenced some production components. Dervisevic et al (2014) reported that the optimal nitrogen rate for fiber flax to the obtained results was 30 kg N/ha.…”

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

“…These findings align with [30], suggesting that linseed, is characterized by great phenotypic plasticity with a considerable adaptability to changes in spacing. The increased stem branching in our fiber flax cultivation agrees with [26], who noted that higher nitrogen soil concentrations were associated with an increased number of stem branches in golden flaxseed. Additionally, flax varieties considered for fiber production typically exhibit less branching, featuring thinner straw and lacking sub-stems [7].…”

“…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.…”

Reintroducing Flax (Linum usitatissimum L.) to the Mediterranean Basin: The Importance of Nitrogen Fertilization

“…The augmentation of the biomass (DM) of the plants due to the application of N fertilization has also been reported by other researchers. Soethe et al [39] noted a positive linear increase while examining the interaction of N fertilization and the biomass of flax plants. In our study, during both experimental years, the dry weight of the plants was significantly affected by fertilization, particularly on treatments with higher fertilization rates (Figure 1).…”
