“…Hatfield et al 35 indicated that the increased CO 2 concentration showed less than 10% positive effects on C4 crop. It has been reported that the negative impacts of climate change on crop productivity could be mitigated by effective agronomic adaptation techniques and seed genetic improvement 9,14,15,19 . Previous modelling studies demonstrated that adjustment of fertilizer over time should be considered in climate change assessment, especially when climatic factors have obvious influence on crop production [13][14][15] .…”

“…Crop rotation diversity is beneficial to improving soil physical quality, nutrient availability and soil microbial diversity, which contributes to high crop yield and low environmental risk [16][17][18] . Ma et al 19 predicted that including legumes in rotation would be advocated for mitigation under a changing climate, which would increase crop yields by about 5% for rainfed agricultural systems in Australia. Therefore, exploring adaptation strategies based on comprehensive agronomic management practices are essential to promoting sustainable maize production in Northeast China under future climate change.…”

Maize (Zea mays L.) production in Northeast China is vulnerable to climate change. Thus, exploring future adaptation measures for maize is crucial to developing sustainable agriculture to ensure food security. The current study was undertaken to evaluate the impacts of climate change on maize yield and partial factor productivity of nitrogen (PFPN) and explore potential adaptation strategies in Northeast China. The Decision Support System for Agrotechnology Transfer (DSSAT) model was calibrated and validated using the measurements from nine maize experiments. DSSAT performed well in simulating maize yield, biomass and N uptake for both calibration and validation periods (normalized root mean square error (nRMSE) < 10%, −5% < normalized average relative error (nARE) < 5% and index of agreement (d) > 0.8). Compared to the baseline (1980–2010), the average maize yields and PFPN would decrease by 7.6–32.1% and 3.6–14.0 kg N kg−1 respectively under future climate scenarios (2041–2070 and 2071–2100) without adaptation. Optimizing N application rate and timing, establishing rotation system with legumes, adjusting planting dates and breeding long-season cultivars could be effective adaptation strategies to climate change. This study demonstrated that optimizing agronomic crop management practices would assist to make policy development on mitigating the negative impacts of future climate change on maize production.

“…Another efficient strategy for climate change mitigation is the inclusion of legumes in farming systems, since it allows to naturally reduce the amount of inorganic N fertilizer, reduce CO 2 emissions, amend soil physical properties, maintain soil fertility and decrease pest susceptibility, as recently reviewed by Karkanis et al (2018). A predictive model that included climate data from the last 80 years demonstrated that the inclusion of a legume in a crop rotation system would decrease 25% of the greenhouse gas emission (Ma et al 2018). Besides decreasing denitrification, the inclusion of legumes in intercropping systems has also contributed to improve P-fertilizer-use efficiency and led to increased plant availability of P, Fe and Zn (Xue et al 2016).…”

Background Global climate is changing more rapidly than ever, threatening plant growth and productivity while exerting considerable direct and indirect effects on the quality and quantity of plant nutrients. Scope This review focuses on the global impact of climate change on the nutritional value of plant foods. It showcases the existing evidence linking the effects of climate change factors on crop nutrition and the concentration of nutrients in edible plant parts. It focuses on the effect of elevated CO 2 (eCO 2), elevated temperature (eT), salinity, waterlogging and drought stresses, and what is known regarding their direct and indirect influence on nutrient availability. Furthermore, it provides possible strategies to preserve the nutritional composition of plant foods under changing climates. Conclusions Climate change has an impact on the accumulation of minerals and protein in crop plants, with eCO 2 being the underlying factor of most of the reported changes. The effects are clearly dependent on the type, intensity and duration of the imposed stress, plant genotype and developmental stage. Strong interactions (both positive and negative) can be found between individual climatic factors and soil availability of nitrogen (N), potassium (K), iron (Fe) and phosphorous (P). The development of future interventions to ensure that the world's population has access to plentiful, safe and nutritious food may need to rely on breeding for nutrients under the context of climate change, including legumes in cropping systems, better farm management practices and utilization of microbial inoculants that enhance nutrient availability.

“…Thus, the response of plants to high temperature events at different growth stages may have important implications for the development of stress tolerance in crops. Heat stress severely affects plant growth and development and is classified as a major abiotic stressor for numerous crops ( Moriondo et al, 2011 ).…”

Heat stress during grain filling substantially decreases wheat productivity; thus, to ensure food security, heat tolerance in wheat needs to be developed. In this study, we evaluated the effect of heat priming applied during the stem-elongation stage, booting and anthesis, followed by 5 days of severe heat stress (a 7.86°C rise in temperature) during the grain-filling stage on physiological activities and grain yield of winter wheat in pot experiments during the 2015-2017 growing seasons using the winter wheat cultivars Yangmai 18 (a vernal type) and Yannong 19 (a facultative type). Compared with the damage observed in non-primed plants, heat priming during the stem-elongation stage and booting significantly prevented the grain-yield damage caused by heat stress during grain filling. Heat-primed plants displayed higher sucrose contents and sucrose-phosphate activity in leaves and greater above-ground dry matter than non-primed plants. Priming during stem elongation and booting led to increased photosynthetic capacity, stomatal conductance and chlorophyll contents in comparison with non-priming. Improved tolerance to heat stress due to the enhanced activities of antioxidant enzymes superoxide dismutase and peroxidase and reductions in reactive oxygen species and malondialdehyde production was observed in primed plants compared with non-primed plants of both cultivars. The positive effect of heat priming on the response to heat stress during grain filling was more pronounced in plants primed at the booting stage than in those primed at the stem-elongation or anthesis stage. Moreover, the vernal-type Yangmai 18 benefited more from heat priming than did Yannong 19, as evidenced by its higher productivity. We conclude that heat priming during early reproductive-stage growth can improve post-anthesis heat tolerance in winter wheat.
