“…Similarly, the lower seed yields observed in 2012 and 2013 could also have been due to the above-mentioned factors, particularly lower seasonal precipitation and lower seasonal GDD (particularly in May) in both growing seasons (Table 1). These suggestions were consistent with multiple reports that showed that water deficit interferes with reproduction in crop plants, thereby reducing grain yields [35,[55][56][57]. Due to the sandy clay nature of soil, factors such as change in stored soil water content, run off, and deep percolation were minimal (approximately zero) in our field plot sites.…”

“…However, a higher seed yield production was obtained by Celine, Columbia, and Yellowstone in the drier years of 2012 and 2013, by Calena in 2012, and Suneson in 2013, compared to their average seed yield in the respective years. The seed yields for C. sativa across the different growing conditions ranged from 425-2867 kg ha −1 [35,56], which agreed with the seed yield range observed in this study. The results from this study suggested that Calena, Celine, Columbia, and Yellowstone might be better suited for dryland production than the other tested cultivars, but additional trials under semi-arid and arid conditions are needed to validate this claim.…”

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.

“…Distribution of irrigation was based on the weather station data and HI was not evapo-transpiration-limited. Actual evapo-transpiration obtained through weather stations operated by the High Plains Climate Center (Changnon et al, 1990) was used to calculate water use (Hergert et al, 2011). The water holding capacity of the soil was 6 cm in the top 30 cm.…”

a b s t r a c tDrought is a periodic occurrence in the High Plains of the U.S.A.; thereby low-water using crops are desired. Canola, a biofuel and food oil, has been studied in the region under rain-fed conditions for several years. The study's objective was to measure plant growth, seed yield, and oil characteristic of canola at four levels of applied water in western Nebraska. The cultivar Hyola 357 Magnum was exposed to rain-fed only (RF), and irrigated with 10 (LI), 20 (MI), and 30 (HI) cm water. Adding irrigation increased plant growth, i.e., canopy height, stem length, and canopy weight. Highest canopy height (>100 cm for MI and HI) was reached by 10 weeks after planting (WAP) with a total of 23 cm of applied water or 13 cm of irrigation. By 8 WAP, canopy fresh weight was increased by 37 to 58% by MI and HI irrigations. Pod fresh and dry weights at harvest (13 WAP) were increased >50% and >20%, respectively, by all irrigations. Seed yield were increased by each incremental increase in irrigation from 1220 kg/ha for RF to 2905 for HI, a 2.4-fold increase. Seed oil content was increased by MI and HI irrigations (4-8%). The fatty acid profile was not substantially altered by irrigation. There was a slight decrease of palmitic acid and increase in linolenic acid with HI. Canola showed that >20 cm of applied water is needed for good vine and pod growth but >40 cm was needed to achieve the highest yield. Canola could be grown successfully in western Nebraska, supplying oil for fuel and cooking.

“…The controlled deficit irrigation ranges from 0 to 600 mm for maize in northern Togo. The DS-CDI strategy seems to save water with an insignificant reduction in the grain yield relative to full irrigation [87][88][89][90][91][92]. Overall, growing maize crop in the dry season in Figure 6b shows the stochastic crop-water production functions (SCWPF) for optimized irrigated maize crop in the dry season in northern Togo.…”

In the context of a growing population in West Africa and frequent yield losses due to erratic rainfall, it is necessary to improve stability and productivity of agricultural production systems, e.g., by introducing and assessing the potential of alternative irrigation strategies which may be applicable in this region. For this purpose, five irrigation management strategies, ranging from no irrigation (NI) to controlled deficit irrigation (CDI) and full irrigation (FI), were evaluated concerning their impact on the inter-seasonal variability of the expected yields and improvements of the yield potential. The study was conducted on a maize crop (Zea mays L.) at a representative site in northern Togo with a hot semi-arid climate and pronounced dry and wet rainfall seasons. The OCCASION (Optimal Climate Change Adaption Strategies in Irrigation) framework was adapted and applied. It consists of: (i) a weather generator for simulating long climate time series; (ii) the AquaCrop model, which was used to simulate the irrigation system during the growing season and the yield response of maize to the considered irrigation management strategies; and (iii) a problem-specific algorithm for optimal irrigation scheduling with limited water supply. We found high variability in rainfall during the wet season which leads to considerable variability in the expected yield for rainfed conditions (NI). This variability was significantly reduced when supplemental irrigation management strategies (CDI or FI) requiring a reasonably low water demand of about 150 mm were introduced. For the dry season, it was shown that both irrigation management strategies (CDI and FI) would increase yield potential for the local variety TZEE-W up to 4.84 Mg/ha and decrease the variability of the expected yield at the same time. However, even with CDI management, more than 400 mm of water is required if irrigation would be introduced during the dry season in northern Togo. Substantial rainwater harvesting and irrigation infrastructures would be needed to achieve that. precipitation patterns [5]. The variation of the food diets in many developing countries compound this problem and lead to the demand for more processed food and animal proteins by consumers [6].The World Bank [7] reports that the rate of increase in food demand is projected to be higher in developing than in developed countries. These are also the regions that are subject to a wide yield gap. The world demand (billion tons) of cereals was 1.20 in 1974, 1.84 in 1997 and is expected to be 2.50 in 2020 [8]. In addition, van Ittersum et al. [9] pointed out that Sub-Saharan Africa (SSA) is the region with lowest food security because by 2050 its demand for cereals will almost triple, whereas current levels of cereal consumption already rely on considerable importations.Lobell and Gourdji [10] pointed out that, in the past several decades, air temperatures have been increasing in most of the main cereal cropping areas around the world. They added that the changes in temperature and the intensity...
