Summary: The impact of climate change on food production in South Africa is likely to increase due to low rainfall and frequent droughts, resulting in food insecurity in the future. The use of well-calibrated and validated crop models with climate change data is important for assessing climate change impacts and developing adaptation strategies.

Summary: This study aims to provide sugarcane yield models for twelve different locations in Muzaffarnagar District, India. The study found that the model performed best under the mid planting date scenario, and also investigated the impact of climate change on sugarcane yield. The findings suggest that higher temperatures result in decreased yield, while increased solar radiation leads to higher yield.

Summary: An extensive comparison between ionospheric foF2 observations and TIE-GCM simulations has been conducted for the equatorial location of Thiruvananthapuram. The TIE-GCM simulations generally reproduced the temporal and seasonal characteristics of foF2 well for different solar activity conditions. However, the model failed to reproduce the bite-out phenomenon observed in 2002. The analysis showed good agreement between the modeled and measured values overall, although the model generally underestimated the observations. The study demonstrates the effectiveness of the model in simulating the temporal, seasonal, and solar cycle variability of ionospheric foF2 over the equatorial Indian region.

Summary: This study examines the biophysical and socio-economic impacts of climate change on groundnut production in India, highlighting the importance of a holistic assessment of these factors. Modelled projections show the sensitivity of climate change impacts to differences in socioeconomic factors, emphasizing the need to consider market effects to gain a comprehensive understanding of how economic and environmental factors impact agricultural food systems and economies.

Summary: The D/H ratio is commonly used to study the history of water on Mars, however, the mechanisms controlling present-day HDO behavior are not well understood. Ground-based observations confirmed significant variations of the D/H ratio, particularly lower HDO/H2O ratios in colder regions of Mars due to isotopic fractionation during condensation. A study exploring the impact of a global dust storm in Martian year 34 found that HDO was 40% more abundant on average at 100 km during the storm year, potentially leading to significant consequences for the escape flux of water that year.

Summary: Rolling hill topography in agricultural land leads to subfield variation in soil resources, which can be stabilized and productivity increased using agroecological methods like cover crops. Field trials and computer simulations demonstrated that cover crops, such as cereal rye, can significantly improve maize yields and reduce variability across different landscape positions and weather scenarios.

Summary: Solar radiation is crucial for crop growth and development, but the lack of weather data, particularly SRAD, is a challenge in many agricultural areas. Recent advancements in gridded weather data provide realistic alternatives to observed weather data. This study evaluated six GRD products and identified that AgCFSR, AgERA5, and AgMERRA have the highest accuracy for crop simulation modeling.

Summary: This study applied sensitivity analysis to a linked DSSAT-MODFLOW modeling system to determine the main factors controlling groundwater storage and crop yield. The results showed that climatic parameters have a significant impact on crop yield, while hydrogeological parameters have a relatively low influence. These findings can be used to investigate the effects of management strategies on groundwater and agricultural sustainability in similar regions under changing climate conditions.

Summary: This paper presents a scheme for applying two-stage explicit stochastic optimization to seasonal irrigation scheduling, yielding results close to optimal but at the cost of increased computation burden. The approach involves solving multiple optimization problems based on different weather scenarios and selecting the irrigation schedule with the highest worst-case yield. This method mimics traditional risk-adverse farmers' strategy and shows an overall improved performance in terms of yield.

Summary: Iran is facing increasing pressure to increase crop production due to population growth and water crisis. The study found that trends in specific crops' production are mainly explained by trends in harvested area, while variability in harvested area contributes more to crop production variability, especially under rainfed conditions.

Summary: This study found that under saline water irrigation, saffron can increase root density, produce larger and heavier corms, and promote Na+ exclusion and K+ accumulation as main tolerance mechanisms, which help it produce a satisfactory economical yield. The foliar application treatments, especially VCE, could negate the negative impacts of salinity by remedying nutrient deficiency and improving aerial K+/Na+ ratio in salinity conditions. Triggering antioxidant defense system was the most notable mechanism of GABA and SA in alleviating the adverse effects of salt stress on saffron.

Summary: A new thermal time model was developed to describe temperature-dependent tuber sprouting of purple nutsedge. The model was able to predict sprouting time, final sprouting, and sprouting rate, while also generating estimates of useful temperature thresholds. The superiority of the absolute sprouting rate index in calculating temperature thresholds was demonstrated.

Summary: This study investigated the effects of changing planting date and crop rotation on rainfed wheat yield in Iran under climate change. The results showed that the impact of climate change and adaptation responses varied spatially, and overall, there is a risk of wheat yield reduction in some regions in the future. However, adjusting planting dates and implementing appropriate crop rotations can improve wheat yield.

Summary: The expression of genes that control germination-related processes in corn is influenced by environmental factors, with hormonal priming facilitating seed germination. Different germination temperatures, salt-induced stress, and priming solutions had varying effects on seed germination percentages and rates. Different hormonal priming treatments were recommended based on temperature conditions to optimize germination outcomes.
