“…In Alberta, camelina seed yield ranged from 1,987 to 3,320 kg ha -1 over two locations near Beaverlodge. In the [23] observed seed yield ranging from 1,096 to 1,660 kg ha -1 over two locations and two seasons, in view of this, seed yield in the present study was considerable indicating promising potentials of cultivating camelina in Southern Ethiopia. Although Nitrogen is reported to increase seed yield in different plants of Brassicaceae family [24].…”

Camelina sativa (L.) Crantz is an ancient oilseed crop. Camelina seed can be used as a food ingredient and raw material for the production of oil. The by-product of camelina oil used as fodder ingredient. But there is no information in Ethiopia about camelina production, so that an experiment was conducted at at Lambuda Hossana area, Southern Ethiopia to investigate the effect of different levels of nitrogen fertilizer on the yield and yield attribute along with different seeding rate of camelina in 2016 cropping year. The treatments were 0, 50, 100 and 150 kg ha-1 and Camelina seeding rate 5, 7.5, 10 and 12.5 kg ha-1. The experiment was laid out in RCBD design with three replications. The result revealed that application of nitrogen has significantly increased the seed yield camelina compared with the control. There was a steady increase in the seed yield of camelina for nitrogen levels from 100 kg ha-1 up to 150 kg ha-1 in the studyarea. Combined analysis of the two treatment factors data showed that still the highest yield was obtained at nitrogen level applied at of 150 kg ha-1 with seeding 10 ha-1. Seeding rate also varied significantly in their performance with respect to yield components and yield ha-1. Accordingly, 10 kg ha-1 performed best relative to the other three seeding rate. It is concluded that there is a significant and positive response of camelina to applied nitrogen and the highest biological and grain yield was obtained at nitrogen level of 150 kg ha-1 with seeding rate of 10kg ha-1. Thus it is recommended that nitrogen fertilizer should be applied in the area to mitigate nitrogen deficiency for enhanced camelina yield.

“…Jiang et al (2013Jiang et al ( , 2014 showed that higher doses of nitrogen increase the percentage of polyunsaturated fatty acids, and reduce the percentage of monounsaturated fatty acids. Wang et al (2017) reported that the camelina was rich in C 18:4,n-3 and in C 20 FA.…”

“…The seeds of camelina can be used universally, eg. : as feed (Steppa et al, 2017;Wang et al 2017) and derived oil from them as food (Vollmann et al, 2007;Mińkowski et al, 2010) as well as technical oil, including biofuel (Karcauskiene et al, 2014;Mohammed et al, 2017). The nutritional value of oil is mainly due to a high content of unsaturated fatty acids, particularly n-3 (omega-3) fatty acids and multiple use values (Zubr and Matthäus 2002;Zubr, 2003a).…”

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.

“…However, only about 1–2% of the total H 2 available is utilized by this pathway (Czerkawski and Clapperton, 1984 ; Hristov et al, 2013 ). The effectiveness of mitigating CH 4 by lipids may be related to their fatty acid composition (recently described by Wang et al, 2017 ). Despite these findings, the shifts occurring in, and the quantitative role of, the individual main microbial groups in this respect are not well known.…”

“…For this purpose, we modified rumen fluid in a way that either only one of the four distinct groups was inhibited or all groups except bacteria. In order to investigate the role of the type of lipid, three oilseeds effective in CH 4 mitigation but largely differing in their composition of PUFA (Wang et al, 2017 ) were chosen as test lipids. This should foster the exhibition of interactions between lipid type and microbial group.…”

Dietary lipids can suppress methane emission from ruminants, but effects are variable. Especially the role of bacteria, archaea, fungi and protozoa in mediating the lipid effects is unclear. In the present in vitro study, archaea, fungi and protozoa were selectively inhibited by specific agents. This was fully or almost fully successful for fungi and protozoa as well as archaeal activity as determined by the methyl-coenzyme M reductase alpha subunit gene. Five different microbial treatments were generated: rumen fluid being intact (I), without archaea (–A), without fungi (–F), without protozoa (–P) and with bacteria only (–AFP). A forage-concentrate diet given alone or supplemented with crushed full-fat oilseeds of either safflower (Carthamus tinctorius) or poppy (Papaver somniferum) or camelina (Camelina sativa) at 70 g oil kg−1 diet dry matter was incubated. This added up to 20 treatments with six incubation runs per treatment. All oilseeds suppressed methane emission compared to the non-supplemented control. Compared to the non-supplemented control, –F decreased organic matter (OM) degradation, and short-chain fatty acid concentration was greater with camelina and safflower seeds. Methane suppression per OM digested in –F was greater with camelina seeds (−12 vs.−7% with I, P = 0.06), but smaller with poppy seeds (−4 vs. −8% with I, P = 0.03), and not affected with safflower seeds. With –P, camelina seeds decreased the acetate-to-propionate ratio and enhanced the methane suppression per gram dry matter (18 vs. 10% with I, P = 0.08). Hydrogen recovery was improved with –P in any oilseeds compared to non-supplemented control. No methane emission was detected with the –A and –AFP treatments. In conclusion, concerning methanogenesis, camelina seeds seem to exert effects only on archaea and bacteria. By contrast, with safflower and poppy seeds methane was obviously reduced mainly through the interaction with protozoa or archaea associated with protozoa. This demonstrated that the microbial groups differ in their contribution to the methane suppressing effect dependent on the source of lipid. These findings help to understand how lipid supplementation and microbial groups interact, and thus may assist in making this methane mitigation tool more efficient, but await confirmation in vivo.
