“…Rain-fed (W0) treatment was used as the control in both growing seasons. The amount of supplemental irrigation (SI) was calculated using Equation [1] (Jalilian et al, 2012): CIR = 100γbd Dh(θt -θn) [1] where CIR (mm) is the amount of SI, γbd (g cm -3 ) is the soil bulk density, Dh (cm) is the depth of the soil layer (140 cm in this study), θt (mg water g -1 dry soil) is the target soil water content (SWC) on a weight basis after SI, and θn (mg water g -1 dry soil) is the water content of the soil on a weight basis before irrigation. θt was calculated using Equation [2] as follows: θt = θmax θr/100…”

Shortage of water resources is a major limiting factor for wheat (Triticum aestivum L.) production in the North China Plain. The objectives of this study were to evaluate the effects of supplemental irrigation (SI) on water use characteristics and grain yield of the wheat cultivars 'Jimai 22'and 'Zhouyuan 9369'. Two supplemental irrigation treatment regimens were designed based on target relative soil moisture contents in 0-140 cm soil layers at jointing rising to 75% of field capacity (FC) for each cultivar, and at anthesis rising to 65% and 75% (W1), and 70% and 80% (W2) in 2009-2010 and 2010-2011, respectively. Rain-fed (W0) treatment was used as control. Under W1, grain yield of 'Jimai 22' was 5.22% higher than that of W2, and water use efficiency (WUE) of 'Zhouyuan 9369' was 4.0% higher than that under W2. No significant differences in WUE of 'Jimai 22' and grain yield of 'Zhouyuan 9369' were observed for the two treatment regimens in 2009-2010. Grain yield and WUE in W1 were higher than those of W2 for both cultivars in 2010-2011. W1 enhanced soil water consumption compared to W2, especially in the 100-200 cm soil layers, for both cultivars in 2009-2011. Meanwhile, 'Jimai 22' showed higher soil water consumption and ET from anthesis to mature stage, which resulted in increase in grain yield and WUE of 'Jimai 22' by 8. 15-21.7% and 7.75-11.73% in 2009-2010 and 2010-2011, respectively, compared with 'Zhouyuan 9369'. Thus, our results showed that SI increased the yield and WUE of 'Jimai 22' and W1 was the better treatment regimen.

“…Singh and Quadri (1984) and Sharma and Gaur (1988) have also reported that decreases in oil content (%) in response to high levels of N was due to the presence of more impurities. Protein synthesis is wholly dependent on the amount of N fertilizer available for plant use (Nasim et al, 2012).The application of N fertilizer also increases protein concentration regardless of the irrigation regime used (Jalilian et al, 2012).…”

“…In western China in particular, a large proportion of the vegetable oil used is sunfl ower oil (Wang and Yin, 2014). Th e quality of the oil is associated with its fatty acid composition, and particularly the proportions of oleic, linoleic, and linolenic acids (Jalilian et al, 2012). In recent years, Chinese people have been making increasing demands on agriculture for healthy food; this is because more and more people are suff ering from cardiovascular disease (Rynan et al, 2015).…”

Core Ideas Topdressing N increase the content of crude fat and linoleic acid in sunflower seeds. More topdressing N reduces the content of protein, oleic acid, and palmitic acid. Crude fat content significantly correlated with protein content in sunflower seeds. Sunflower (Helianthus annuus L.) has emerged as a very important crop in China due to the economic value of vegetable oil production. A 2‐yr field experiment was conducted in 2013 and 2014 to determine the effect of different N fertilizer application levels on the oil quality of a sunflower hybrid Kang Di T562 grown in the Hetao irrigation district, a sub‐arid region in China. The effects of N fertilizer were evaluated for three characteristics of oil from sunflower seeds: crude fat content (CFC), protein content, and fatty acid composition. The results showed that N fertilizer application had a significant effect on CFC, protein content, and fatty acid composition (oleic acid, linoleic acid, palmitic acid, stearic acid). When basic N fertilizer (68 kg ha−1) was used, subsequent topdressing N applications at the end of budding promoted the synthesis of protein, palmitic acid, and oleic acid in the oil of sunflower seeds, but decreased the CFC and linoleic acid content. There was a significant negative correlation between CFC and protein content (P ≤ 0.05) and between oleic acid and linoleic acid (P ≤ 0.01) in oil from sunflower seeds. There were positive and negative correlations among the main quality indices of sunflower seed. To increase the content of crude fat and linoleic acid in the oil of sunflower seeds, topdressing should not be used, or its use should be reduced, although this could reduce the content of protein, oleic acid, and palmitic acid.

“…All of the SI treatments brought the relative SWC in each measured soil layer to 65% FC at jointing (Z31, first node detectable) and 70% FC at anthesis (Z61, beginning of anthesis) (Zadoks et al, 1974). The required amounts of SI were calculated by the equation described by Cuenca (1989) and Jalilian et al (2012): where CIR (mm) is the amount of SI; y bd (g cm −3 ) is the soil bulk density; D h (cm) is the thickness of the soil layer measured for SWC before SI (Table 2); θ t (%) is the target Figure 2. the daily precipitation during the 2012-2013 and 2013-2014 winter wheat growing seasons.…”
