The seeding depth was approximately 10-15 mm for . Although the actual origin of this crop is uncertain, most studies report that the crop likely originated in southeastern Europe and southwestern Asia [2, 3]. We thank Lee Gilbertson, Reshma Thapa and Christopher Owusu for technical support. Citing Literature Volume 58, Issue 5 September-October 2018 Pages 2089-2098 Related Previous studies on impact of seeding rate on camelina yield often suggest that yield is not reduced by low plant populations due to growth plasticity of camelina plants [23, 24, 25]. Home > Ideally, some seed should be observed on the soil surface. No seedling damage has been seen at temperatures as low as 12 F in Montana. For camelina, seeding rate was 4.92 kg ha 1 of pure live seed (PLS). camelina meal approvals for all animal uses. Camelina is naturally resistant to flea beetles. Camelina has high oil and protein content. The recommended sowing rate ranges from 3 to 7 kg/ha (approximately 250 to 600 seeds/ m 2), with the objective of producing a stand density in the range of 125 to 200 plants/m 2. The seeding rate study showed that camelina had a weak response to seeding rates supporting the theory that the crop has a great capacity to compensate for yield at low plant densities.

Dear Growers,I am responsible for Camelina seed scale-up and commercial contract production, and I am very excited about introducing this crop to growers in the United States and Canada. Our team is growing all the time, so were always on the lookout for smart people who want to help us reshape the world of scientific publishing. However, we also observed the yield compensation capacity is influenced by environmental conditions. Maximum and average temperature throughout the crop growing period for camelina grown at Brookings and Pierre, SD in 2015, 2016 and 2017 (numbers in parentheses indicate deviations from 1981 to 2010 average). This study investigated the response of camelina seed yield and quality, and agronomic traits to applied N (5 levels, 0, 28, 56, 84, 140 kg ha1) and four seeding rates (4.5, 9, 13, 17.5 kg ha1). Optimum seeding rates for camelina range from 4 to 6kgha1 [8]. Camelina seeds are dense and small at 345,000 to 500,000 seeds per pound and can be broadcast or drilled. The low oil concentration at Pierre is most likely due to overall lower precipitation and higher temperature throughout the growing season.

Temperature and rainfall data were collected at weather stations located within each farm throughout the crop growing period in both years (Tables 2 and 3). Kinder Morgan Energy Partners, L.P. (NYSE: KMP) today announced plans to invest up to $100 million to expand its terminal facilities to help serve the growing biodiesel market. In 2017, 112kgha1N and 22kgha1S in the form of urea (46% N) and ammonium sulfate (21% N and 24% S) mixture was applied in a split application to ensure continuous supply of N. The first application occurred at planting and the second application occurred around the bolting stage. These results show that although considered a low-input crop, camelina can respond positively to high N rates in high yielding environments as indicated by a linear response to N rate observed at a high yielding environment in Brookings. The field experiments were arranged as randomized complete blocks with three replicates for each test location. Camelina has been approved as a cattle feed supplement in the US, as well as an ingredient (up to 10% of the ration) in broiler chicken feed and laying hen feed which offers an additional revenue stream. The increase in seed yield with increasing N rate was linear in a high yielding environment and quadratic in a low yielding environment. The erucic acid (C 22:1) content of camelina oil is variable depending on the genotypes and can range 2.11 to 4.30% [10] higher than the maximum allowed in food grade rapeseed oil (2%) [11]. Camelina Harvesting Harvest of early-planted Camelina typically occurs in July and can be harvested with unmodified combines and may be direct combined standing or swathed. The effects of N fertilizer on seed yield of camelina have been reported by other researchers [20, 21, 22]. [25] reported that seeding rate strongly affected plant population but that seed yield response to seeding rate was weak. 5 Princes Gate Court, All plot areas were seeded to a depth of 0.25 inch on April 28 with a small commercial John Deere grain drill, (6-inch row spacing), at the rate of 8.0 lb/ac of raw seed. author = "Gesch, {Russ W.} and Matthees, {Heather L.} and Alvarez, {Adriana L.} and Gardner, {Robert D.}". In 2015, plots were planted on 3 April at Brookings and 16 April at Pierre. The fertilizer was broadcast manually using an automatic hand-held spreader to ensure even application. Gesch, Russ W. ; Matthees, Heather L. ; Alvarez, Adriana L. et al. management. Variation in some key traits was identified among cultivars that may benefit breeding programs by improving winter camelina productivity and increasing its use in dual-cropping systems. Necessary cookies are absolutely essential for the website to function properly. Two replications for all treatments were sent to SGS Mid-West Seed Services, Inc. (Brookings, SD, USA) for oil content analysis using a hexane solvent extraction. The objectives were (1) to determi In their study and in the current study, higher rates of N increased plant lodging. In 2016, both Brookings and Pierre had lower than average rainfall in June and July, coinciding with bolting, flowering, and seed filling periods, a critical time for seed development and quality. Joelle had the greatest winter survival rate, averaging 64% across three growing seasons. This suggests that higher seeding rates may be necessary to help compensate for reduced stand establishment in drier environments under no-till. Some call it low input. Small yield increases were seen with seeding rates greater than 100 seeds m-2. It is a short-seasoned, fast-growing crop that can help spread your workload. As PhD students, we found it difficult to access the research we needed, so we decided to create a new Open Access publisher that levels the playing field for scientists across the world. Average stand at Frederick's was 260,000 plants per acre; at Johnson's was 302,500 plants per acre; and at Stout's was 777,000 plants per acre. Seeding at 334 seeds m2 was sufficient to achieve maximum seed and oil yield. Plant stand counts were lowest in Brookings in 2017 (216 plant m2). Seeding rate had a significant impact on seed yield at Brookings and Pierre in 2016 but seed yield was not affected by seeding rate at Brookings in 2017. proof that good things really do come in small packages. The two camelina varieties used in the study performed the same for most measured traits except for number of pods per plant and seed oil concentration at Pierre in 2016 and seed yield at Brookings in 2017. At Brookings in 2015, N rates of 28 to 140kgha1 yielded the same and significantly greater than the control. The suggested seeding rate per acre varies slightly among states, but averages 5 lb/acre. Poast, a post Because the oil is high in omega-3 (linolenic) and omega-6 (linoleic) acids and low in saturated fatty acids, the crop is considered a high quality edible oil. perhaps even again before the camelina emerges to ensure the crop gets North America as a weed. options, it is not as dependent on rain later in the summer when Mother However, few studies have compared winter cultivars for variation in key agronomic traits, or have addressed optimizing seeding rate for their production. Previous research seem to agree however, that seed oil content decreases as N application rate increases [18, 20, 22]. Both HPX-WG1-35 and HPX-WG4-1 flowered earlier than the other two cultivars and had greater seed protein content. Camelina was planted on an average of five dates at each site (n=55) from early October to mid April at a rate of 5 lbs/acre by either drilling seed at a shallow depth or broadcasting seed on the soil surface. Oil content of the seed, on a dry weight basis, is typically between 30 and 40 percent. [23] reported no response to seeding rate and attributed the lack of response to plasticity of camelina and therefore the crops ability to compensate for lower plant densities. Seeding rate and camelina variety effects on plant height, seed yield, and pod shatter in camelina grown at Brookings, SD in 2017. Camelina seed oil concentration as a function of nitrogen fertilization rate at Brookings and Pierre, SD in 2015 and 2016. The lack of change in pod number as seeding rate increased at Pierre is likely due to poor stand establishment resulting in lower plant populations at all seeding rates. Camelina (Camelina sativa L. Crantz,) a new oilseed crop in the Brassicaceae family has favorable agronomic traits and multiple food and industrial uses. In 2014, camelina was initially seeded on 101, 114, and 125 DOY. In one four-year study, crops were sown with standard farm machinery on large plots in late fall on stubble, without seedbed preparation or herbicides, or conventionally in the spring. While the current results agree with the above observation, our results further suggest this ability to compensate for lower plant densities is likely influenced by environmental conditions. By continuing you agree to the use of cookies. This makes the oil fit for biofuels production and the meal a Camelina has high oil and protein content. This association is difficult to explain since earlier reports [24] suggest that stand reduction at rosette stage of camelina delays plant maturity. Seeding Rate: 500-2500 lbs/acre. Camelina oil mainly consists of poly- and mono-saturated fatty acids. allows ground to absorb later-season rainfall so it can enter the new The N rate effects on plant height were significant at both locations in 2016 but were not significant in 2015 at both locations (Tables 4 and 5). The result revealed that application of nitrogen has significantly increased the seed yield camelina compared with the control. Camelina is viewed as a desirable alternative biodiesel crop because of its apparent lower cost of production (i.e., water, fertilizer, pesticides, and seeding rate) relative to other more common oilseeds being produced, such as soybean, canola, and sunower (Frohlich and Rice 2005; Pilgeram et al. In the northern Plains, camelina is planted in early spring and harvested in late July most years. A ShapiroWilk test was used to test for normality. How? While Camelina is resistant to most diseases, it is susceptible to Downy Mildew and Sclerotinia. The project was funded by the South Dakota Oilseeds Initiative, USDA-NIFA and South Dakota Agricultural Experiment Station. Harvest when the seed is fully mature and hard. allows an even earlier start to the growing season. The recommended seeding rate is 5 - 6 pounds per acre, which will be provided with no upfront seed costs. These results agree with previous research on camelina where plant height increased with increasing N rate was inconsistent among environments [20]. Treatments included five different N fertilizer rates: 0, 28, 56, 84, and 140kgNha1, and one camelina variety (S-40).

Averaged across locations and sowing dates, Joelle camelina under the HD seeding rate yielded 24 % more seed than the LD rate (1212 versus 977 kg ha 1, for HD and LD, respectively, P 0.05). S6). Camelina meal can be used as animal feed including cattle, swine and poultry [12, 13, 14] and has been reported as a potential aquaculture feed [15]. Camelina may be planted with a grain drill or by broadcast seeding fol-lowed by a packer. Both HPX-WG1-35 and HPX-WG4-1 flowered earlier than the other two cultivars and had greater seed protein content. It should do very well on coarser textured or shallow, droughty soils. All plots were treated with a pre-planted incorporated herbicide and half of all camelina, and canola plots were treated with post-emergence herbicide. Download Table | Effect of seeding rate on stand count of camelina from publication: The effect of seeding rate, seeding date and seeder type on the performance of Camelina sativa L. in the . Camelina has no seed dormancy. I am confident that Camelina can be a successful crop for farmers, and I look forward to working with growers to drive adoption of this crop. Stand establishment varies depending on tillage practices, environmental conditions and variety and therefore higher seeding rates are often recommended to avoid stand losses due to poor seedbed conditions. Number of pods per plant and seeds per pod were measured at both locations only in 2016. Site description and soil characteristics at the 015cm depth for the two South Dakota locations where studies were conducted in 2015 and 2016. At a drier environment in Pierre, on the other hand, the greatest seed yield was obtained at a seeding rate of 13kgha1 with this yield similar to the yield obtained with a seeding rate of 9kgha1 but significantly greater than the yield obtained at the lowest seeding of 4.5kgha1 and the highest seeding rate of 17.5kgha1. Data on crop production is still somewhat limited since the USDA did not start data collection until 2007. Accelerated growth and short growing seasons in semi-arid environments negatively impacts seed maturity and oil accumulation resulting in low seed oil concentrations [33]. In 2017, the planting dates were April 24 at Brookings. Other researchers have also reported inconsistent results on camelina seed yield response to seeding rate. The photo is of our recent germ test of this seed. Treatments included four different seeding rates (4.5, 9, 13, and 17.5kgha1) and two camelina cultivars (SO-40 and SO-50) arranged in a factorial design to give a total of eight treatments. Gesch et al. 20-21 Lbs of Seed will produce ~ 1 gallon of oil. have seen success with fall, or dormant, seeding of camelina, which This means further evaluations under different environmental conditions are warranted. However, few studies have compared winter cultivars for variation in key agronomic traits, or have addressed optimizing seeding rate for their production. established, but it is not a miracle crop. Table 1. The previous crop was Barley. All farms seeded the camelina at the same rate: 8 lb/ac. These cookies do not store any personal information. There was a steady increase in the seed yield of At Brookings in 2016 and 2017, plant stand counts significantly increased with every seeding rate increase (Tables 6 and 7). Overall, the 2015 growing season had rainfall and temperature conditions closer to the 30-year average at both locations. However, plants in thin stands are more exposed the elements of wind thus causing more pod shatter. or aviation biofuel that performs similar to fuels from other sources The authors would like to thank Joe Boots, Charles Hennen, and Scott Larson for their expert field assistance in maintaining experimental plots and collecting and processing plant samples. To validate the substantial contribution of the photosynthetic pod wall to seed metabolism, camelina leaves or pods present at the beginning of seed development were shaded (fig. Traits such as freeze hardiness and improved seed yield and quality would benefit large-scale adoption of winter camelina. Camelina has natural pod shatter resistance and can be straight cut using conventional combines. UNITED KINGDOM, Thandiwe Nleya, Dwarika Bhattarai and Phillip Alberti, Physiological, Agricultural and Ecological Aspects, Nitrogen in Agriculture - Physiological, Agricultural and Ecological Aspects. it, we think it spells a new profit opportunity for farmers in the US Attain Tetraploid Annual Ryegrass Seed - 50 Lbs. KMP has entered into long-term agreements with Green Earth Fuels, LLC to build up to 1.3 million barrels of tankage that will handle approximately 8 million barrels of biodiesel production at KMP's terminals on the Houston Ship Channel, the Port of New Orleans and in New York Harbor. Camelina spreads workload and reduces risk. Traits such as freeze hardiness and improved seed yield and quality would benefit large-scale adoption of winter camelina.
