“…Liang et al 35 demonstrated that in China, multi-cropping system will expand northward in the future (2050s) and may contribute to an increase in yield potential. Zhang et al 19 found that double cropping rice systems could experience an overall decrease in yield in the future without considering the effects of CO 2 , but early rice yields could still increase if the effect of CO 2 is taken into account. Kawasaki et al 36 compared double cropping rice-wheat systems with single cropping systems and found that the area of double cropping could double in the future, with rice yields in mid-and southern Japan maintaining similar yield levels, and wheat yields decreasing by 5-10%.…”

“…Hampf et al 37 found that climate change could negatively impact second season crops in Southern Amazon, but technical progresses are expected to offset these effects. In contrast to previous studies 19,[35][36][37] , we focused on double cropping systems in Europe. To achieve this, we implemented a hybrid modeling approach integrating a process-based model with machine learning to estimate and map the probability of successful implementation of maize-wheat double cropping in Europe and its productivity under current and future climate conditions.…”

“…We revealed that a warmer future climate in the future will expedite crop maturity 19,39,40 , and this would result in a shorter growing cycle for crops, increase the likelihood of successfully implementing double cropping, expand the regions where double cropping can be used (Fig. 1, Supplementary Fig.…”

Double cropping can help reduce the risk of food insecurity by harvesting two crops each year instead of one. By increasing the rate of plant development and shortening growing seasons, global warming is likely to favour this type of system in areas where it is not yet being applied. Here we assess the probability of success of double cropping maize and wheat in Europe under global warming. We compare the caloric productivity of this double cropping system with that of conventional single cropping systems with maize and wheat in rotation, using a hybrid modelling approach combining a process-based model and machine learning. Our results show that the decrease in caloric production of simple maize and wheat cropping systems due to climate change could be offset by the adoption of a double cropping system. We show that the geographical area where the double cropping system could be successfully applied will be 3.6 times higher in 2100 than the current level, due to the effect of warming (range from 2.6 to 4.8 Deg. C), leading to an increase in calorie production throughout Europe. In Southern Europe, the expected increase in calorie production reaches even 27.3% (19.2% for maize, 8.1% for wheat) compared to a single cropping system. Our study highlights the potential of double cropping as a relevant adaptation strategy for cropping systems in Europe.

“…Studies of the relationship between climate change and crop yields can be dated back to the early 20th century [ 8 , 9 , 10 , 11 ]). Recent research, with the utilisation of climate models based on extensive observational data [ 12 ], has revealed that climate change impacts the growth and yield of various crops in complex ways, involving factors like temperature, precipitation, and carbon dioxide concentration [ 13 ].…”

The possible influence of global climate changes on agricultural production is becoming increasingly significant, necessitating greater attention to improving agricultural production in response to temperature rises and precipitation variability. As one of the main winter wheat-producing areas in China, the temporal and spatial distribution characteristics of precipitation, accumulated temperature, and actual yield and climatic yield of winter wheat during the growing period in Shanxi Province were analysed in detail. With the utilisation of daily meteorological data collected from 12 meteorological stations in Shanxi Province in 1964–2018, our study analysed the change in winter wheat yield with climate change using GIS combined with wavelet analysis. The results show the following: (1) Accumulated temperature and precipitation are the two most important limiting factors among the main physical factors that impact yield. Based on the analysis of the ArcGIS geographical detector, the correlation between the actual yield of winter wheat and the precipitation during the growth period was the highest, reaching 0.469, and the meteorological yield and accumulated temperature during this period also reached its peak value of 0.376. (2) The regions with more suitable precipitation and accumulated temperature during the growth period of winter wheat in the study area had relatively high actual winter wheat yields. Overall, the average actual yield of the entire region showed a significant increasing trend over time, with an upward trend of 47.827 kg ha−1 yr−1. (3) The variation coefficient of winter wheat climatic yield was relatively stable in 2008–2018. In particular, there were many years of continuous reduction in winter wheat yields prior to 2006. Thereafter, the impact of climate change on winter wheat yields became smaller. This study expands our understanding of the complex interactions between climate variables and crop yield but also provides practical recommendations for enhancing agricultural practices in this region

“…Therefore, it is crucial to consider the effects of climate change and planting date on crop production and modeling to improve crop yields. Identifying the optimal planting time for new cultivars in each region is the most significant and controllable factor for maximizing crop yields, as stated in a study by Zhang et al (2023). The selection of an appropriate planting time is crucial for optimizing plant growth stages and achieving maximum yield by utilizing natural resources efficiently during the growing seasons, according to a study by Safaei et al (2017).…”

Fennel is a herbaceous plant widely used for both medical and aromatic purposes, owing to its economic and pharmacological benefits. This study investigated the effects of different sowing dates on the growth, yield, and quality of fennel plants under arid and semi-arid conditions of Aswan governorate. Three different dates were explored; 15 th Oct, 1 st Nov and 15 th Nov for two successive seasons 2020/2021 and 2021/2022. The results showed that sowing date significantly influenced the vegetative and yield characters of fennel. Plants sowed on 15 th Oct had the best growth and yield characteristics, including the tallest plants, the highest fruit weight per plant, and the highest fruit yield per Fadden. The highest percentage and yield of essential oil were observed in plants sowed on 1 st Nov in the first season, and in plants sowed on 15 th Oct in the second season. The findings suggest that sowing fennel on 15 th Oct could lead to the highest yield and quality, which could be economically beneficial for farmers in arid and semi-arid regions.
