“…It has also been observed that decreasing soil water availability under I 1 , I 2 and I 3 irrigation treatments caused significant reduction in yield and development of yield contributing traits in camelina genotypes during both growing seasons. These results are consistent with the findings of [ 20 – 22 ]. The highest decrease in yield and yield contributing traits of both genotypes was observed when irrigation was skipped at vegetative and flowering stages (I 3 ).…”

“…Oil and protein yields (kg ha −1 ) of camelina (S1 and S2 Figs) also decreased under water deficit conditions (I 1 , I 2 and I 3 ) compared to normal irrigation (I 0 ). These results are in accordance with the previous findings, revealing a significant decrease in oil and protein yields of camelina [20][21][22] and canola [30] under limited supply of water. The possible reason of this reduction in oil and protein yields would be the decrease in seed yield because oil and protein yields are the output of seed oil and protein contents multiplied with seed yield [30].…”

“…An appropriate flood irrigation management for camelina is quite necessary in water limited arid and semiarid conditions [18]. Previous studies on camelina irrigation needs under different agro climatic conditions demonstrated an increase in seed yield with higher water volumes and this information is somewhat limited [19][20][21][22][23]. However, no considerable attention has been paid to evaluate the impact of water deficit on physio-biochemical and yield productivity responses in camelina, when imposed at different growth stages.…”

“…Since limited water supply principally harms the crop vegetative, flowering, seed setting and seed filling growth stages [ 24 ]. Additionally assessing the performance of contrasting genotypes under variable irrigation regimes will help to select suitable genotype that could perform better in water limiting conditions [ 22 ]. Since there is limited information in the literature regarding physio-biochemical expressions, seed yield, oil and protein responses against water deficit stress employed at different growth stages in camelina.…”

Differential physio-biochemical and yield responses of Camelina sativa L. under varying irrigation water regimes in semi-arid climatic conditions

Camelina sativa L. is an oilseed crop with wide nutritional and industrial applications. Because of favorable agronomic characteristics of C. sativa in a water-limiting environment interest in its production has increased worldwide. In this study the effect of different irrigation regimes (I0 = three irrigations, I1 = two irrigations, I2 = one irrigation and I3 = one irrigation) on physio-biochemical responses and seed yield attributes of two C. sativa genotypes was explored under semi-arid conditions. Results indicated that maximum physio-biochemical activity, seed yield and oil contents appeared in genotype 7126 with three irrigations (I0). In contrast water deficit stress created by withholding irrigation (I1, I2 and I3) at different growth stages significantly reduced the physio-biochemical activity as well as yield responses in both C. sativa genotypes. Nonetheless the highest reduction in physio-biochemical and yield attributes were observed in genotype 8046 when irrigation was skipped at vegetative and flowering stages of crop (I3). In genotypic comparison, C. sativa genotype 7126 performed better than 8046 under all I1, I2 and I3 irrigation treatments. Because 7126 exhibited better maintenance of tissue water content, leaf gas exchange traits and chlorophyll pigment production, resulting in better seed yield and oil production. Findings of this study suggest that to achieve maximum yield potential in camelina three irrigations are needed under semi-arid conditions, however application of two irrigations one at flowering and second at silique development stage can ensure an economic seed yield and oil contents. Furthermore, genotype 7126 should be adopted for cultivation under water limited arid and semi-arid regions due to its better adaptability.

“…Seed yield of camelina vary by location and management, and generally ranges from 500 to 1800 kg ha -1 in semiarid regions of the US Great Plains (McVay and Khan, 2011;Sintim et al, 2015;Mohammed et al, 2017;Obour et al, 2018), and yield ranges of 1000 to 2800 kg ha -1 has been reported in the Mediterranean region of Europe (Vollman et al, 2007;Berti et al, 2011;Jankowski et al, 2019;Krzyzaniak et al, 2019). In Iran, camelina seed yield of 3200 kg ha -1 was reported when grown with irrigation (Amiri-Darban et al, 2020).…”

Nitrogen and sulfur application effects on camelina seed yield, fatty acid composition, and nutrient removal

et al. 2021

Effective management of nitrogen (N) and sulfur (S) in camelina [Camelina sativa (L.) Crantz] production is important to ensure optimum seed yield and oil composition. The objectives of this study were to determine camelina seed yield, oil concentration, estimate nutrient removal and N use efficiency as influenced by N and S application. Field experiments were conducted to evaluate S rates (0 and 20 kg ha-1) and N fertilizer rates (0, 22, 45 and 90 kg ha-1) effect on camelina productivity and fatty acid composition over two growing seasons (2014 and 2015). Results showed S application had no effect on seed yield and oil concentration. Averaged across N rates, protein concentration increased with S application compared to the control. Seed yield showed quadratic response to N fertilizer application with maximum yield occurring at 54 kg N ha-1. However, economic optimum N rate ranged from 18 to 43 kg N ha-1. Nutrient removal, protein concentration, protein and oil yield, and estimated biodiesel was maximum at 45 kg N ha-1. The maximum amounts of N, phosphorus (P), potassium (K) and S removed were 49, 8, 10, and 7 kg ha-1, respectively. Nitrogen use efficiency (NUE) and agronomic efficiency (NAE) decreased when N fertilizer rates were above 22 kg N ha-1. Application of N or S had no effect on proportions of saturated fatty acid (SFA), monounsaturated fatty acid (MUFA), and polyunsaturated fatty acids (PUFA). Our findings suggest camelina required 18 to 43 kg N ha-1 when grown in rain-fed systems in water-limited environments.
