“…This method has been widely used to study the N fertilizer use efficiency (Harmsen, 2003). Some studies have shown that plant N uptake could be affected by climate warming (Nam et al, 2013; Zhang et al, 2013; Xu et al, 2015), while the fates of 15 N fertilizer (recovery, residual, and loss) in response to asymmetric warming is still not clear. In the present study, plant N uptake from basal 15 N and top-dressed 15 N was increased in night-warming treatments compared with NW during each growth stage, and WSW resulted in higher increases than WW and SW (Table 2).…”

“…Fertilizer N in wheat-soil system had three fates: uptake by wheat, residual in soil, and loss from the wheat-soil system (Shi et al, 2012). Several studies reported that the plant N uptake could be affected by climate warming (Sardans et al, 2008; Kim et al, 2011; Nam et al, 2013), which could potentially affect the residual and loss of N fertilizer. For example, Cheng et al (2010) reported that high night temperature increased plant above ground biomass, and had no effect on plant N concentration, resulted in significantly improved plant N uptake of rice.…”

To develop efficient N management strategies for high wheat NUE and minimizing the environmental impact of N losses under asymmetric warming, 15 N micro-plot experiments were conducted to investigate the effects of night-warming during winter (warming by 1.47–1.56°C from tillering to jointing), spring (warming by 1.68–1.82°C from jointing to booting), and winter + spring (warming by 1.53–1.64°C from tillering to booting) on root growth and distribution of winter wheat, the fates of 15 N-labeled fertilizer, and their relationships in 2015–2017. The results showed that night-warming increased the recovery of basal 15 N and top-dressed 15 N, while reduced the residual and loss of basal 15 N and top-dressed 15 N. The losses decreases of top-dressed 15 N were higher than those of basal 15 N, indicating that night-warming reduced losses of fertilizer 15 N mainly by reducing losses of top–dressed 15 N. Moreover, pre-anthesis root dry matter accumulation rate in 0–60 cm soil layer were promoted, resulted in improved root biomass and root/shoot ratio, which favored increasing recovery of fertilizer 15 N and reducing losses of fertilizer 15 N. Furthermore, residual fertilizer 15 N content in 0–100 cm soil layer was reduced, which was associated with improved root weight density in 0–60 cm soil layer, resulted in reduced leaching losses of fertilizer 15 N. The path analysis showed that root dry matter distribution in 0–20 cm soil layer was the most important in contributing to reducing losses of total fertilizer 15 N compared with other soil layers. Two years data showed that winter and spring night-warming gave better root growth and distribution in 0–20 cm soil layer, resulted in reduced the losses of fertilizer 15 N and improved the recovery of fertilizer 15 N, while maximizing grain yield of winter wheat, and winter + spring night-warming resulted in higher advantages than winter night-warming and spring night-warming.

“…The ability to respond and maintain growth enhancement under FACE is expected to depend on an adequate supply of nutrients. In rice, increases in root biomass due to elevated [CO 2 ] allow the plant to exploit more N from the soil (Nam et al 2013). Previous studies on rice have demonstrated that root dry matter is a good predictor of the plant's ability to take up nutrients (Kim et al 2001); N content and dry matter were positively correlated for individual rice organs and the whole plant (Kim et al 2011).…”

Elevated CO2 concentrations ([CO2]) in the atmosphere often increase photosynthetic rates and crop yields. However, the degree of the CO2 enhancement varies substantially among cultivars and with growth stage. Here, we examined the responses of two rice cultivars, Wuyunjing23 (WYJ) and IIyou084 (IIY), to two [CO2] (~400 vs ~600) and two nitrogen (N) provision conditions at five growth stages. In general, both seed yield and aboveground biomass were more responsive to elevated [CO2] in IIY than WYJ. However, the responses significantly changed at different N levels and growth stages. At the low N input, yield response to elevated [CO2] was negligible in both cultivars while, at the normal input, yield in IIY was 18.8% higher under elevated [CO2] than ambient [CO2]. Also, responses to elevated [CO2] significantly differed among various growth stages. Elevated [CO2] tended to increase aboveground plant biomass in both cultivars at the panicle initiation (PI) and the heading stages, but this effect was significant only in IIY by the mid-ripening and the grain maturity stages. In contrast, CO2 enhancement of root biomass only occurred in IIY. Elevated [CO2] increased both total N uptake and seed N in IIY but only increased seed N in WYJ, indicating that it enhanced N translocation to seeds in both cultivars but promoted plant N acquisition only in IIY. Root C accumulation and N uptake also exhibited stronger responses in IIY than in WYJ, particularly at the heading stage, which may play a pivotal role in seed filling and seed yield. Our results showed that the more effective use of CO2 in IIY compared with WYJ results in a strong response in root growth, nitrogen uptake, and in yield. These findings suggest that selection of [CO2]-responsive rice cultivars may help optimise the rice yield under future [CO2] scenarios.

“…Although the experimental operation matters, the different magnitude combinations of temperature and CO 2 concentration set were a key reason causing the differences between their results. This also resulted in differences in the dry matter accumulation and distribution among rice organs in recent studies (Wang et al, 2019a;Nam et al, 2013;Cheng et al, 2010). The temperature and CO 2 concentration are closely coupled at a long-term temporal scale, and the combinations of these two variables in the experimental chambers may not reflect the actual long-term relationship between them.…”

“…Crop models are driven by various combinations of temperature and CO 2 concentration generated with general circulation models (GCMs) (Kim et al, 2013;Iizumi, Yokozawa & Nishimori, 2011;Tao et al, 2008). These combinations are based on the physical relationship between these two variables, overcoming the drawback of the often randomly set values in the experimental chambers.…”

In this study, we investigated the effects of temperature frequency trends on the projected yield and dry matter distribution of japonica rice (Oryza sativa L.) with elevated carbon dioxide (CO2) under future climate change scenarios in northwestern China. The Crop Environment Resource Synthesis (CERES)-Rice model was forced with the outputs from three general circulation models (GCMs) to project the rice growth and yield. Future temperature trends had the most significant impact on rice growth, and the frequency of higher than optimal temperatures (∼24–28 oC) for rice growth showed a marked increase in the future, which greatly restricted photosynthesis. The frequency of extreme temperatures (>35 oC) also increased, exerting a strong impact on rice fertilization and producing a significantly reduced yield. Although the increased temperature suppressed photosynthetic production, the elevated CO2 stimulated this production; therefore, the net result was determined by the dominant process. The aboveground biomass at harvest trended downward when temperature became the major factor in photosynthetic production and trended upward when CO2-fertilization dominated the process. The trends for the leaf and stem dry matter at harvest were affected not only by changes in photosynthesis but also by the dry matter distribution to the panicles. The trends for the rice panicle dry matter at harvest were closely related to the effects of temperature and CO2 on photosynthetic production, and extreme temperatures also remarkably affected these trends by reducing the number of fertilized spikelets. The trends of rice yield were very similar to those of panicle dry matter because the panicle dry matter is mostly composed of grain weight (yield). This study provides a better understanding of the japonica rice processes, particularly under extreme climate scenarios, which will likely become more frequent in the future.
