Summary: This paper investigates deep learning models and color space models for automatic tomato harvesting, proposing the use of SSD MobileNet v2, YOLOv4, and an HSV color space model. Experimental results show that YOLOv4 performs the best in both tomato detection and classification tasks, with high F1-Score and macro F1-Score, while the HSV color space model achieves similar results to the YOLOv4 model.

Summary: The demand for new herbicide modes of action has surged due to the evolving resistance of weeds to existing commercial herbicides. Natural products possess many potential new modes of action that have not been utilized by current herbicides, but have yet to be developed for various reasons. Efforts are being made to identify new herbicide targets through pharmaceutical target sites, metabolomic and proteomic information, and the use of artificial intelligence and machine learning. It is likely that new herbicides with new modes of action will be introduced within the next decade to address herbicide resistance management.

Summary: This study discusses various strategies for second-generation bioethanol production from corncobs, focusing on the effects of different pretreatment methods, detoxification methods, and fermentation approaches on ethanol yield. The results show that a combination of acid and alkali pretreatments along with proper detoxification steps can achieve high ethanol yields. Additionally, using genetic engineering to construct inhibitor tolerant and consolidated bioprocessing compatible microbes is another way to achieve an economical process.

Summary: The study found that the factors influencing fruit yield and water use efficiency were irrigation amount, fertilization rate at the fruit expansion stage, and fertilization rate at the flowering stage, while the factors influencing water, vitamin C and carotenoid contents in fruit were irrigation amount, fertilization rate at the fruit ripening stage, and fertilization rate at the fruit expansion stage. Additionally, the factors influencing soluble solids and total sugar contents were irrigation amount, fertilization rate at the fruit ripening stage, and fertilization rate at the flowering stage.

Summary: Humic acids (HA) play essential roles in improving soil properties, plant growth, and agronomic parameters. They positively affect soil physical, chemical, and biological characteristics, as well as crop growth, nutrient uptake, and yield. Factors such as HA type, application rate, mode, and soil type influence the effects of HA on soil and crops.

Summary: In this study, the drought stress of maize in the Northeast China Plain (NECP) and North China Plain (NCP) over the past 20 years was evaluated using remote sensing data and meteorological data. A conceptual model was established to analyze the response of maize biomass to drought stress. The findings provide new insights for preventing drought stress risk and improving maize yield on a large scale.

Summary: This study evaluated the effects of direct and partial sunlight on the essential oil yield, chemical profile, and biological activities of Kaempferia parviflora. It was found that partial shade conditions resulted in higher essential oil yield and superior antioxidant, anti-inflammatory, anti-cholinesterase, tyrosinase, and anti-diabetic activities compared to direct sunlight conditions.

Summary: This study integrated habitat and quality assessment of Panax notoginseng for its potential distribution in China under climate change conditions. Results showed that suitable habitats were mainly distributed in central and eastern Yunnan Province, but were predicted to decrease and move to high-altitude areas in the future. The saponin content in highly suitable habitats was relatively low, with temperature and precipitation playing key roles in the distribution of P. notoginseng.

Summary: This study investigated the irrigation demands of rice in southern China by analyzing six representative rice areas. The results showed that the differences in irrigation demand among different types of rice were mainly influenced by the distribution and quantity of rainfall. With the increasing trend in rainfall and better utilization, rice irrigation demands may be further reduced or completely stopped in the future.

Summary: The scarcity of irrigation water is a major constraint for global crop production, especially for potato growth in arid and semiarid regions. Field experiments were conducted to study the effects of irrigation amount, fertilizer rate, and potato variety on potato yield, quality, and water and fertilizer productivity. The results showed significant impacts of these factors on potato growth, with Feiurita variety performing better than Xiapoti variety. The W2F3V1 and W3F2V1 treatments were recommended as the best water and fertilizer management in sandy loam soils in Northwest China.

Summary: Adhesives traditionally made from fossil-based polymers have issues of toxicity, environmental pollution, and non-renewable raw materials. Therefore, research on environmentally friendly and renewable adhesives from bio-based materials has gained attention. Lignin, a natural and renewable phenolic polymer with various functional groups, has been extensively studied for its exploitation. Despite some progress, developing lignin-based adhesives with performances surpassing fossil-based adhesives remains challenging.

Summary: "Pest management is facing significant economic and environmental challenges worldwide due to excessive use of pesticides. Plant-based pesticides offer a sustainable and cost-effective alternative, with their effectiveness, availability, low toxicity, and rapid biodegradability. However, formulation difficulties and limited chemical data have hindered their global acceptance. This review aims to highlight the current usage, phytochemical compositions, insecticidal mechanisms, and challenges of plant-based pesticides in sustainable agricultural production."

Summary: Little is known about the dynamics of P fractions and bacterial communities in the rhizosphere of legumes in karst soils. In this study, a field experiment was conducted to investigate P uptake, rhizosphere P fractions and bacterial community structure of soybean in response to P fertilization. Results showed that rhizosphere acidification during soybean cultivation led to changes in P fractions and bacterial community composition. Phosphorus fertilization further affected soil pH and different P fractions, leading to alterations in bacterial community composition, especially in soils without P input.
