“…However, this reason does not fully explain yield results in SD2. The lowest yields in 2015-2016 were similar to those obtained by Gutiérrez and Albalat [24] in the nearby county of Aragon, or those by Gesch & Archer [18] and Obour et al [35] (0.5 Mg ha −1 ), while others approximated more to French et al [36] (1Tn ha −1 ), or even to McVay and Khan [19] and Obour et al [35] (1.5 Mg ha −1 ), as yields of 2016-2017. Meanwhile, yields from 2017-2018 were more like those from Gesch [25] (2.3 Mg ha −1 ) or Zubr [37], who obtained yields of 2.6 to 3.3 Mg ha −1 in Denmark.…”

Crop rotation in winter cereals in semiarid Mediterranean climates is highly desirable to prevent weed infestations, but the climatic conditions make it difficult to implement alternative crops to winter cereals. Camelina (Camelina sativa (L.) Crantz) is an interesting option, as it is able to produce profitable yields thanks to its tolerance to cold and drought. In this work, three autumn–winter sowing dates (SD1, October; SD2, December; SD3, January) and two sowing rates (R1, 8 kg ha–1; R2, 11 kg ha–1) were chosen to evaluate the effectiveness of these cultural methods to control weeds over three seasons, and to determine effects on camelina seed yield. Results showed that a significant reduction of weed coverage was obtained by delaying the sowing date. Sowing rates did not show differences in weed coverage. In contrast, no apparent yield penalty was observed among sowing dates and rates. These results show that the introduction of camelina as a rotational crop in semiarid Mediterranean climates is a feasible option for helping to suppress winter weeds, as well as to provide productive seed yield in these climatic conditions.

“…This sowing flexibility also allows for a wider window of opportunity to make decisions. Despite this, some productivity decreases have been reported [35] in winter wheat the following season when it follows camelina in rotation. This aspect should also be studied to better understand this issue.…”

“…Grain yield, aboveground biomass, protein content, total N uptake, and NUE increased with reduced tillage. These effects results in high water use efficiency of the crop (Blanco-Canqui et al, 2017;Obour et al, 2018). Also, increased crop residue by reduced tillage can help keep the soil surface cool and reduce soil temperature and loss of water by evaporation (Licht and Al-kaisi, 2005).…”

Tillage and Biochar Effects on Wheat Productivity under Arid Conditions

Urea is an important source of inorganic N under wheat (Triticum aestivum L.) production system in Multan, Pakistan. However, the average N loss is high, ranging from 22 to 53% of applied N, which poses adverse environmental impacts. Reduced tillage and combined application of biochar and optimal N fertilizer could improve wheat productivity and reduce N losses. We evaluated the effects of two tillage (conventional and reduced tillage), two biochar (no biochar and poultry waste biochar), and three inorganic N rate (0, 60, and 120 kg ha−1) treatments on productivity and economic profitability of wheat production for two continuous growing seasons (2014–2015 and 2015–2016). Generally, reduced tillage increased wheat grain yield, protein content, and total N uptake by 0.2 Mg ha−1, 3.0 kg kg−1, and 37.0 kg ha−1, respectively, when compared with conventional tillage. Biochar application increased wheat grain yield, protein content, and total N uptake by 0.3 Mg ha−1, 6.8 kg kg−1, and 38.6 kg ha−1, respectively, compared with no‐biochar plots. Reduced tillage was economically profitable within the two cropping seasons, but biochar application was not, because of the high price of biochar (US$1.00 kg−1 biochar) and application rate (10 Mg biochar ha−1). Overall, wheat production under reduced tillage, no biochar, and the 60‐kg N ha−1 rate resulted in the greatest economic profit in this study.

“…C. sativa is currently grown in the traditional flax-growing regions of the Upper Midwest of the United States (i.e., Minnesota, North Dakota, South Dakota, and Montana) and Canada, among many other areas throughout the world including Europe, Asia, and Australia [10]. The rapid-cycling oilseed can be used in crop rotations [11,12] or in mixed intercropping systems, often with soybean, maize, or winter wheat [12][13][14].…”

Five-Year Field Trial of Eight Camelina sativa Cultivars for Biomass to be Used in Biofuel under Irrigated Conditions in a Semi-Arid Climate

et al. 2020

View full text Add to dashboard Cite

Camelina sativa is a promising oilseed crop used for dietary oil and as a biofuel feedstock. C. sativa is a highly adaptable, cool season crop that can be grown on marginal lands with minimal inputs, making it potentially suitable for growth in Northern Nevada and other cooler and drier semi-arid regions of North America. A five-year (2011 to 2015) field trial was conducted to evaluate the seed yield, oil content, and oil and biodiesel production potential of eight C. sativa cultivars in semi-arid regions of Northern Nevada. Columbia, Cheyenne, Calena, and Blaine Creek were ranked as the top four varieties based on the five-year study of mean seed yield, oil content, and estimated oil and biodiesel production values, although none of the cultivars were significant (p > 0.05). Overall, Columbia displayed the highest seed yield, harvest index, oil yield and potential biodiesel production of 910 kg ha−1, 0.147, 273.4 kg ha−1, and 86.4 L ha−1, respectively, across five growing seasons. For each individual year across the eight cultivars, seed yield, oil content, oil and potential biodiesel production was highest in 2015, and lowest in 2012 and 2013 (the drier years). The seed yields of this study fall within the ranges of yields reported in both the irrigated and rainfed locations of the Western United States. Based on the seed yield, oil, and the estimated oil and biodiesel productivity reported in this study, C. sativa can be grown successfully with supplemental irrigation in semi-arid environments like Nevada.
