Special Issue Information

Dear Colleagues,

Climate change is a major threat to food production worldwide. Rain patterns and temperature are changing in many production areas, affecting yields and diseases, which, in turn, affect different crops. Developing strategies to cope with this new scenario is a major challenge for 21st century agronomy. This ambitious objective cannot be undertaken with a single strategy; solutions may come from biotechnology, microbiology, ecophysiology, engineering, and organic farming. In this issue, we want to compile papers related to the adaptation of crops to climate change, accepting papers from different areas and disciplines that are focused on the aforementioned objective. We are also interested in novel technologies, such as CRISPR/Cas9 or new breeding techniques with high potential for use in the development of novel and improved crops, able to maintain yield levels under the novel conditions imposed by climate change.

For this Special Issue, we welcome papers related to the following topics:

  • Biotechnological improvement of crops to enhance adaptation to climate change;
  • Use of biostimulants, PGPR, or mycorrhizal fungi to improve crop adaptation to climate change;
  • Field studies under new conditions imposed by climate change;
  • Organic farming strategies to adapt crops to climate change;
  • Ecophysiological studies of crop plants under abiotic stress conditions;
  • Metabolic engineering of phytohormones for abiotic stress tolerance.

Diminishing soil fertility and crop productivity due to traditional intensive cultivation has prompted the use of straw and manure to improve soil health in Northeast China. However, few comparative studies have explored the influence of varying straw and manure incorporation depths on crop growth. A field experiment in the rainfed black soil regions of Gongzhuling and Keshan assessed the effects of deep (30 cm) and shallow (15 cm) incorporations of straw and manure on soil fertility, maize root growth, and maize productivity. Deep incorporations, via subsoiling tillage (DST) and deep-plow (DDT) tillage, enhanced soil water storage of 30–100 cm soil layer during periods of low rainfall, improved the availability of nutrients (nitrogen, phosphorus, and potassium) and soil organic matter content, especially in deeper soil, compared to shallow incorporation using rotary tillage (SRT). Both DST and DDT induced a larger rooting depth and a higher fine root (diameter class 0–0.5 mm) length density by 31.0% and 28.9%, respectively, accompanied by reduced root turnover. Furthermore, the sub-surface foraging strategies of roots under the DST and DDT treatments boosted the total nitrogen, phosphorus, and potassium uptake (6.5–17.9%) and achieved a higher dry mass accumulation during the later growth period, thus leading to notable improvements in the 100-kernel weight and yield (16.1–19.7%) and enhancing water- and nutrient-use efficiencies by 2.5–20.5%. Overall, compared to shallow incorporation, deep incorporation of straw and manure significantly enhances root growth and spatial distribution of soil water and nutrients, which has great potential for increasing maize yield in rainfed agricultural areas.

The southern rice-growing region plays a crucial role in ensuring national food security in China. However, rice production in this area is often affected by unfavorable weather conditions such as rainy and dim days, which significantly impact rice yield. Therefore, we conducted two field experiments to explore and compare the effects of climate variations and simulated shading on rice yield and quality. The results indicated that (a) both interannual climate variation and simulated shading had adverse effects on rice yield and quality, (b) the impact of interannual climate variation on yield was less severe compared with simulated shading, but it had a more significant negative effect on rice quality, and (c) different cultivars/quality groups of rice exhibited variations in response to weak solar radiation, with high-quality rice being more susceptible. The findings suggest that in the production of high-quality rice, it is important to select cultivars that are resilient to interannual climate variation and to develop supporting cultivation techniques to cope with growing incidence of weakened solar radiation in the future. Breeders can try to tap into potential weak-light-resistance genes and cultivators can try to use different cultivation methods to determine the optimal water and fertilizer regimes. Full article

Quinoa is a resilient crop known for its adaptability to diverse environmental conditions. This study examined the agronomic performance and ecological adaptability of quinoa across four distinct altitudes in the northwestern regions of China. Six quinoa genotypes were assessed for agronomic traits, phenology and yield performances, and nutritional quality characteristics in Yining city, Nilka County, Tekes County and Zhaosu County under varied environmental conditions. Our findings demonstrate significant variations in all measured traits, including agronomic and nutritional quality traits, across the various altitudes and genotypes. In Yining city, a warmer and lower altitude area, genotypes exhibit superior traits for fodder production, including increased branches, longer panicles, robust stems, and high seed protein content. Genotypes Jinli 1 and Beijing 2 achieve yields exceeding 3 tons per hectare (t/ha), highlighting the region’s productivity. The Nilka and Tekes counties boasted the shortest quinoa crop cycles, with Jinli 1 yielding 4.05 t/ha seeds in Tekes County, exhibiting high protein and fat content alongside low saponins, making it a prime location for yield production. Zhaosu County, with its cooler climate and fertile chernozem soil, elicited high 1000 seed weight and more robust protein response than Nilka and Tekes counties, illustrating the impact of soil fertility on nutritional composition. Correlation analyses further elucidated that the plants characterized by shorter flowering times, crop cycles, compact inflorescence, and taller heights exhibited superior seed yields. Our study contributes significant insights into the ecological adaptability and nutritional dynamics of quinoa, with implications for sustainable crop production and food security in diverse agroecosystems.

As one of the world’s principal food crops, rice sustains over half of the global population. With global climate change intensifying, the frequency of extreme high temperatures is increasing, posing significant threats to the growth and development, yield, and quality of rice, thereby jeopardizing global food security. This study reviews the impacts of high temperatures on rice at different developmental stages and summarizes previous research on heat tolerance cultivation techniques for rice. Currently, to enhance heat tolerance in rice, the following strategies were primarily adopted: (1) the exploration of heat-tolerant genetic resources and breeding of heat-tolerant varieties; (2) cooling through canopy temperature management via enhanced transpiration regulated by water management; (3) the scientific application of fertilizers to promote the accumulation of assimilates in rice; (4) the application of exogenous regulators to bolster the antioxidant capacity of rice. The implementation of these strategies not only helps to ensure rice yield and quality but also provides robust support for addressing the challenges that global warming poses to agricultural production.
