“…In treatments with seeding rates of 200, 300, and 400 seeds m −2 , the 1,000 seed weight of seeds supplied with 50 kg N ha − 1 was determined at 1.02, 0.98, and 0.87 g, respectively, and the 1,000 seed weight of camelina fertilized with 100 kg N ha − 1 was determined at 1.13, 1.00, and 0.93 g, respectively. An increase in the 1,000 seed weight of camelina in response to increasing nitrogen rates from 0 to 200 kg N ha − 1 was also reported by Jiang and Caldwell (). However, Solis, Vidal, Paulino, Johnson, and Berti () found that nitrogen fertilization had no significant effect on 1,000 seed weight.…”

“…The most appropriaterate of nitrogen fertilizer has been estimated at 60-80 kg N ha −1 in Atlantic Canada (Urbaniak, Caldwell, Zheljazkov, Lada, & Luan, 2008) and at 120-160 kg N ha −1 in eastern Canada (Jiang, Caldwell, Falk, Lada, & MacDonald, 2013); whereas in the Canadian prairies, the highest yields were reported in response to a fertilizer rate of 170 kg N ha −1 (Malhi et al, 2014). The results of research studies analyzing the effects of different rates of nitrogen fertilizer on camelina yields are ambiguous and often contradictory (Jiang & Caldwell, 2016), which could be attributed to strong yield compensation mechanisms in different environments, such as the increase in the number of seeds per silique or the increase in seed weight (Mason & Guillen-Portal, 2010).…”

The aim of this study was to evaluate the effect of nitrogen fertilization (0, 40, 80, 120, 160 kg N ha−1) on changes in selected physical, thermal, and geometric parameters of camelina seeds. Samples 0 kg N ha−1 and 40 kg N ha−1 formed a homogenous group with lower values of 1,000 seed weight and differed significantly from the second homogeneous group of samples 80, 120, and 160 kg N ha−1 with higher 1,000 seed weight. Nitrogen fertilization did not exert a significant effect on bulk density, true density, or porosity. Fertilization had no significant effect on the thermal properties of camelina seeds. Based on all linear dimensions and shape factors, samples 0 and 40 kg N ha−1 formed one homogenous group and were significantly different from the remaining samples. Samples 0 and 40 kg N ha−1 were characterized by the lowest values of linear dimensions, including length, width, surface area, profile specific perimeter, and convex perimeter, the lowest values of selected shape factors, including diameter range, standard deviation of all radii, Blair‐Bliss coefficient, and Danielsson coefficient, as well as the highest values of the radius ratio and roundness. Practical Applications Nitrogen fertilization strongly influences the properties of camelina seeds. Camelina seeds subjected to 120 kg N ha−1 were characterized by the highest dimensions, such as: length, width, surface area, and high values of 1,000 seed weight and they may be most desirable to be used in practice.

“…In our study, based on N source, rate, and cultivar, grain production of camelina ranged from 534 to 1,010 kg/ha and falls within the range of 127 to 3,303 kg/ha reported from studies in several countries across the globe (Czarnik, Jarecki, & Bobrecka‐Jamro, ; Malhi et al, ; Sintim et al, ; Solis, Vidal, Paulino, Johnson, & Berti, ). Based on camelina grain yield response in this study, applying N beyond 80 kg/ha did not result in a significant increase in grain yield but other studies have reported a wide variation in camelina grain yield response to N rates, ranging from 56 to 200 kg N ha ‐1 (Jiang & Caldwell, ; Jiang et al, ; Sintim et al, ; Solis et al, ). This wide range of N required for optimum grain production is heavily dependent on genotype used, environmental conditions, and management approaches utilized in growing grain crops like camelina (e.g., Setiyono et al, ).…”

The objective of this two-year study (2016-2017 spring) carried out at the University of Nevada, Reno Main Station Field Laboratory, Reno, NV, was to evaluate the effects of nitrogen source, rate, and camelina cultivar on grain yield and potential biodiesel production irrigated with reclaimed water. Treatments were two sources of urea fertilizer [conventional urea (CU) and polymer-coated urea (PCU)], four N rates (0, 40, 80, and 120 kg N ha -1 ), and two cultivars of camelina ("Blaine Creek" and "Pronghorn") arranged in a 4 × 2 × 2 factorial combinations with four replications each in a RCBD experiment. Plot size was 7.6 m long × 1.8 m wide, and camelina was seeded at a rate of 5 kg PLS seed ha -1 .The quantity of light intercepted increased linearly from 44.9% to 65.9% as N application rate increased from 0 to 120 kg N ha -1 , and it was greater for CU (59.6%) compared to PCU (54.0%) fertilized plots. There was a linear increased in grain yield ranging from 534 to 1,010 kg/ha as N application rate increased from 0 to 120 kg N ha -1 . In Year 2, grain yield of Blaine Creek (898 kg/ha) was greater than that of Pronghorn (464 kg/ha). Also, there was a linear increase in estimated biodiesel from 51.2 to 94.2 L/ha as N application rate increased. For both grain and biodiesel production, there was no advantage of using controlledrelease PCU fertilizer and 80 to 120 kg N ha -1 is sufficient for the cultivation of camelina in this environment. Based on the range of grain yield obtained in this study, camelina can be a potential alternative crop to integrate into the annual crop production cycle in water-limited environments like Nevada.

“…An important agricultural treatment is also a mineral fertilization. Like other cultivated plants in the family Brassicaceae (Brassicaceae Burnett) false flax strongly respond to nitrogen fertilization (Solis et al, 2013;Jiang and Caldwell, 2016;Waraich et al, 2017).…”

False flax (Camelina sativa L.), is an oil plant, of the Brassicaceae (Cruciferae) family. It is a rediscovered crop with multiple uses, it is a frost proof, low-soil and climatic conditions plant. In Poland the variety is not very widespread, despite of its health benefits. The particular value of camelina oil is given by its content in polyunsaturated fatty acid (50-60%), by its content in omega 3 (35-40%) and by its content in omega 6 (15-20%). The seeds are used for the extraction of oil (used in medicine or as bio fuel) or directly as animal feed. The research was carried out in the years 2012-2014 at the Experimental Station of Cultivar Assessment in Przecław, Poland. The summer Camelina sativa cv. ‘Omega’was used for the experiment. The studied factors were: A-plant density (200, 300, 400 pcs. m-2) and B-nitrogen fertilization (50, 100 kg∙ha-1). With the increase of the sowing density significantly increased plant density after emergence and before harvest, but reduced the number of silicles per plant. Increase in the rates of sowing from 200 to 400 pcs. m-2 decreased the 1000 seeds weight. Sowing 200 seeds m-2 compared to higher norms had significant effect on reduction the number of seeds in silicle, seed yield and the content of the seeds Fe, but resulted in an increase in the content of the seeds Mn and Zn. On the other hand, sowing 400 seeds m-2 caused a reduction the protein in the seeds, K, and Mg, and an increase fat yield and crude fat content in seeds. The higher nitrogen dose significantly increased the number of silicles per plant, total protein content, Fe, Zn in the seeds, seed yield, yield total protein and the percentage of linoleic and linolenic acids, while reduced the number of seeds per silicle, the crude fat content in seeds and the percentage of oleic acid.
