Summary: Crop planting timing is critical for crop growth and estimation of yields. Traditional methods to acquire planting dates have limitations. In this study, a novel CropSow modeling framework is developed to estimate field-level planting dates by integrating remote sensing phenological detecting method and crop growth model. The CropSow model outperforms benchmark models in crop planting date estimation, showing better generalization performance and adaptability to abnormal weather conditions. It holds promise for large-scale estimation of crop planting timing.

Summary: This study examined the impact of climate change on tropical root and tuber crops in India using the crop model WOFOST. Results indicated that future crop yields will vary depending on climate change. Based on predicted yield variations and economic factors, cassava, sweet potato, greater yam, elephant foot yam, and taro can be considered as preferred crops in the future.

Summary: Region-specific guidelines for maize management are essential in the US Great Plains. This study aimed to define maize yield environments, explore optimal planting date and hybrid maturity combinations, and identify different windows for maximizing yields. Historical weather data from 70 sites were used to analyze maize field dataset and simulate yields using the APSIM model. Results showed that long-maturing hybrids achieved greater yields, while late planting increased stability in central environments. Short-season hybrid maturities allowed for anticipation of physiological maturity date without yield penalties. The study suggests adopting region-specific guidelines to optimize yield and intensify maize-based farming systems.

Summary: Planting date, seeding rate, relative maturity, and row spacing are key factors affecting soybean yield. Maximizing canopy cover before flowering improves seed yield. Combining early planting, optimum cultivars, high seeding rate, and narrow row spacing can significantly increase yield and profit compared to conventional practices.

Summary: By using process-based crop models, the performance of novel genetic combinations can be virtually examined under untested environmental scenarios and management practices. However, there is often a misalignment between the data needed for these models and the data routinely collected by breeding programs. This study leverages a dataset from a long-term trial on advanced experimental lines and released varieties to calibrate and evaluate a crop model, and investigates the potential of shifting planting dates and using shorter duration varieties for future climate adaptation.

Summary: Successful cultivation of crops and livestock in the Northern High Plains is hindered by various factors, but introducing sunn hemp could enhance sustainability. Studies have shown that planting sunn hemp between June 8th and June 18th in NHP maximizes biomass accumulation and provides high nutritive value.

Summary: Synchronizing nitrogen fertilization with planting date can enhance resource use efficiency and profitability of upland rice production in Thailand. Applying 90 kg N ha(-1) of nitrogen fertilizer and planting at the end of September or start of October can maximize profitability. Long-term field investigations and adopting forecasting measures to adjust the planting date are recommended.

Summary: Planting dates play a crucial role in rainfed agriculture, and modifying them can be a major adaptation strategy under climate change. However, shifts in rainfall seasonality may constrain farmers' ability to adapt planting dates, and imperfect knowledge of farmers' current planting date selection makes it difficult to predict how adaptations will proceed. The study found that planting dates are better correlated with easily observed onset definitions based on rainfall frequency than with climatological definitions.

Summary: Weather has both positive and negative impacts on agriculture and is the most uncontrollable factor affecting crop production. Previous studies have rarely investigated the effects of tropical cyclones on agriculture. This study quantified the role of tropical cyclones on crop quality and yield in the Coastal Southern U.S. region, with findings showing that major hurricanes have a significant correlation with crop loss. These results provide essential risk management information for producers and can inform decision-making related to tropical cyclone impacts.

Summary: This study used satellite remote sensing imagery and land use data to quantitatively describe the crop planting structures in the Liangzhou District of the Shiyang River Basin. The ET of major cash crops was inverted using the three-temperature model. The results showed significant spatial heterogeneity in ET during the growing season, and temperature exhibited the highest correlation with ET.

Summary: A dynamic model based on the diffusion process of a chemical to a growing potato tuber was proposed, which showed a significant impact of tuber development on the distribution of chlorpyrifos concentrations. The dynamic model yielded better predictions compared to the classic model in terms of chlorpyrifos uptake into potatoes.

Summary: This study aimed to test long-term trends in planting dates of gladiolus for marketing purposes on Mother's Day and All Souls' Day in Santa Maria, Brazil. Historical temperature data was used to simulate optimal planting dates, revealing no significant change for Mother's Day but a delayed trend for All Souls' Day in certain cultivars.

Summary: The study found that, under future climate conditions, potential yield and rain-fed yield losses of summer maize can be reduced with appropriate measures, while the yield loss of spring maize is smaller. Changing sowing date and planting density has a greater impact on spring maize yield, and the influence weakens as climate change intensifies. Therefore, it is necessary to investigate other adaptation measures to cope with climate change in the Guanzhong Plain of China.

Summary: Drought is a pressing issue worldwide, and selecting wheat genotypes adapted to changing climatic conditions is crucial. This study evaluated 156 bread wheat genotypes, including landraces and modern varieties, under different drought treatments. The results showed that landraces had higher yield stability and protein content under drought stress, suggesting their potential for developing drought-tolerant modern wheat varieties. Effective utilization of landraces in breeding programs is important for developing climate-resilient wheat varieties.

Summary: This study evaluated the changes in nutrient uptake, nutrient use efficiency, and yield of 20 cotton cultivars released in the USA between 1953 and 2018. The results showed that modern cotton cultivars have increased total nutrient uptake but slower improvement in nutrient use efficiency. The findings highlight the potential for enhanced nutrient uptake traits in cotton.
