Summary: This study evaluated the adaptability and stress memory response of cultivated soybean under drought stress. The findings suggest that priming stress prior to drought stress can significantly improve the plant's response to drought, leading to better water status and stronger expression of stress-related genes.

Summary: The combination of elevated atmospheric carbon dioxide concentration and drought will significantly impact wheat production and quality. The response of wheat genotype phenology to elevated carbon dioxide and drought has not been studied before. This study found that elevated carbon dioxide had a significant effect on plants grown under drought, particularly on the booting stage and carbon assimilation rate. However, there was no effect on transpiration rate and grain protein content. The complex water x carbon dioxide x genotype interaction highlights the need to account for multiple factors when modeling wheat response to future climate change.

Summary: Peanut pod yield and its response to fertilizer-K are influenced by the interaction between the environment and plant density. Planting density and K fertilization have a greater impact on rainfed areas than irrigated environments. Increasing plant density leads to an increase in peanut leaf area index and dry matter accumulation, but a decrease in stomatal conductance, particularly in rainfed fields. The application of 50 kg ha(-1) of K in low-K soil can increase leaf K concentration, stomatal conductance, and yield in rainfed fields, while in irrigated fields, yield increases up to a certain plant density and does not further increase with higher densities or K application.

Summary: Planting with non-film mulching is an effective method to reduce residual film pollution in cotton fields. This study used the calibrated WOFOST model and an early mature cultivar to simulate cotton growth and evaluate planting suitability in Xinjiang. The results showed that the model accurately simulated phenological development and yield, and indicated the influence of temperature on cotton maturity in different regions. The study provides a method for assessing the adaptability of filmless cultivation techniques for cotton in different counties.

Summary: Soybean is an important legume crop with high protein content. Drought stress poses severe threats to soybean growth and production. The genetic control of drought tolerance in soybean is not fully understood yet. Developing drought-tolerant soybean varieties is crucial for sustainable production and quality. Molecular techniques and conventional breeding methods have been used to develop drought-tolerant soybean cultivars. Further studies are needed to understand soybean response to drought stress and improve drought tolerance.

Summary: This study utilized NDVI time series to analyze planting and harvesting dates for corn and soybean in Kentucky, finding delays in planting and harvesting dates for both crops, as well as an increase in growing season length for corn and a decrease for soybean. Sensitivity analysis showed planting dates were more affected by early season temperature, while harvesting dates were correlated with temperature throughout the entire growing season. Increased summer precipitation was found to be related to delayed corn harvesting dates in Kentucky. Additionally, delayed corn harvesting dates and extended growing season length were correlated with increased corn yield.

Summary: In this study, it was demonstrated that ectopic expression of AtSINA2 in soybean improved shoot growth, grain yield, drought tolerance, and seed oil content in transgenic plants. Physiological analyses showed that the increased drought tolerance was accompanied with higher chlorophyll content and lower malondialdehyde accumulation and water loss. Transcriptomic analyses revealed that the expressions of genes related to plant growth, flowering, and stress response were regulated in transgenic soybean under normal and drought stress conditions. These findings suggest that AtSINA2 can improve agricultural production and drought tolerance in soybean.

Summary: The trend of drought-induced yield losses in U.S. agriculture has been increasing despite financial investments and technological development. Evaluating drought impacts on crop production is crucial as climate change worsens drought conditions. This study assessed the effectiveness of modified Standardized Precipitation Indices (SPIs) and Standardized Precipitation Evapotranspiration Index (SPEI) in evaluating drought impacts on maize and soybean yields in the southeastern U.S. Results showed that the modified SPI can be as effective as SPEI in assessing drought impacts. Drought events during critical growth stages significantly affected yield variability, and irrigation reduced the sensitivity to drought.

Summary: Improving water use efficiency for soybean through selection for high carbon isotope ratio may increase drought tolerance, but it may limit growth in productive environments. This study aimed to identify genomic regions associated with carbon isotope ratio plasticity, stability, and overall ratio in diverse soybean accessions. Genome-wide association mapping identified several SNPs and candidate genes associated with these traits, which can be utilized for genomic selection to improve drought tolerance in soybean. Different accessions exhibited varying levels of carbon isotope ratio plasticity.

Summary: A modeling system was used to calculate the resource footprints in agricultural production systems in Iran, with the highest land footprint observed in pulses and oil grains. The lowest water footprint was found in silage corn, while the highest water footprints were observed in oil grains. The production of energy, fuel, electricity, and GHG emissions were higher in irrigated cropping systems compared to rainfed systems. Livestock and poultry products, especially red meat, had the highest ecological footprint among the products.

Summary: The study focused on the challenge of high Genotype by Environment by Management (GxExM) interactions in groundnut production in India as a case study for rainfed crops. By assessing the relevance of five groundnut production areas and possibly re-defining them into homogeneous production units (HPUs), the research aimed to address production fluctuations and identify region-specific breeding objectives. The results indicated large and variable yield gaps, with water deficit being a major limiting factor, and the use of HPUs significantly reduced variance in actual and simulated yields, suggesting potential for boosting productivity through targeted crop improvement programs.

Summary: This study investigates the impact of climate change on alfalfa crop in Iran using simulation models and global circulation models. Despite increasing temperatures, the forage yield of alfalfa is projected to increase in most regions due to factors such as spring regrowth, increased cuttings, extended growing season, and positive effects of CO2 on photosynthesis. Climatic changes have significant effects on the irrigation water requirement of alfalfa, which is directly related to its yield.

Summary: Accurately estimating crop yield under climate change scenarios is crucial for meeting food demands. However, there is a lack of comprehensive assessment for soybean, the main source of protein, in terms of climate change impact. In this study, ten models were used to simulate soybean yield under varying temperature and CO2 concentration. The results showed significant variability among models, highlighting the need for further development and experimentation to reduce uncertainty.

However, a comprehensive estimation of yield potential and gap across major potato producing regions in Iran is lacking. This study found that potato producers in Iran achieved only 45% of the potential yield. By closing the yield gap and increasing potato production, it is possible to decrease the amount of cultivated land.
