Summary: Potassium (K) is often overlooked in intensive agricultural systems, but it is essential for improving crop yield and quality. This study examined the effects of fertilizer application and straw management on crop K uptake and soil K changes in dryland winter wheat mono-cropping systems. Results showed that N and P fertilizers increased grain yield and grain K uptake, while straw return decreased them. Soil K depletion was observed even with straw return, indicating the need for K fertilizer. Improving straw-returning rate and managing K fertilizer rationally are crucial for sustainable wheat production.

Summary: The study found that adding biochar, especially wheat raw biochar, significantly increased rice yield and the availability and content of nitrogen, phosphorus, and potassium in plants. Additionally, the availability and content of iron, manganese, zinc, and copper in rice and wheat grains and straw also significantly increased. However, the water-washing process altered the properties of biochar, particularly the water-extractable carbon, decreasing its efficiency.

Summary: Based on a long-term field experiment on the Chinese Loess Plateau, this study found that ammoniated straw incorporation significantly increased winter wheat yield and yield stability, as well as soil organic carbon and total nitrogen content. This suggests that optimizing straw management strategies can lead to higher crop yield and improved soil quality in semi-arid areas.

Summary: This study investigated the anaerobic digestion of Sargassum muticum (SM) with and without pretreatments. Mechanical pretreatment was found to increase methane yield, but the overall yield was still relatively low compared to other substrates. Co-digestion with wheat straw (WS) was recommended for SM, but further research is needed to improve the anaerobic digestion performance of SM.

Summary: This study investigated the influence of wheat straw return on the yield and grain quality in different direct-seeding rice production systems. The results showed that wheat straw return reduced the yield and grain quality of direct-seeding rice but improved the cooking quality of the grain.

Summary: In this study, genomic prediction models were developed for breeding of hybrid crops, which can predict the additive and non-additive effects within and across different heterotic groups. This could potentially improve hybrid breeding and increase genetic gain.

Summary: In the Ethiopian Upper Blue Nile Basin, agricultural productivity is declining due to longer dry seasons and soil acidity-induced fertility problems. Wheat, a major food security crop, is experiencing reduced productivity due to water scarcity, especially during the irrigation season. Addressing these problems is crucial for increasing productivity.

Summary: The pretreatment of wheat straw using liquid digestate was found to be the most effective method for improving anaerobic digestion, with the highest methane yield observed. Microbial communities in the anaerobic digesters were dominated by specific bacteria at different stages, suggesting their potential as indicators for the anaerobic co-digestion process. Factors such as total solid and SO42--S contents in the solid digestate and NH4+-N concentration in the liquid digestate were found to significantly influence the microbial community in the digesters.

Summary: In this study, it was found that no tillage with wheat straw mulching had better regulation on photosynthetic physiological characteristics and had a greater impact on the increase in grain yield of maize compared to conventional tillage with wheat straw incorporation and without wheat straw returning. The no tillage with wheat straw mulching method effectively regulated the growth and development of maize and resulted in a 15.6% increase in grain yield compared to the control treatment. It is recommended to use this method to enhance the grain yield of maize in arid conditions.

Summary: The spatial distribution of irrigation and nutrients in soil significantly affects crop growth and water productivity. Applying irrigation in deep soil layer can increase grain yield and water productivity under water deficit conditions, while locating nutrients in deep soil layer may decrease crop yield and water productivity.

Summary: This study collected 202 peer-reviewed publications to compare the effects of plastic mulch (PM) and straw mulch (SM) on crop yields and soil quality. The results showed that PM significantly increased grain yields in mono crops, while SM had better agronomic performance in long-term experiments. However, SM had a more remarkable improvement on soil quality, making it a better choice for addressing the challenges of food security, soil degradation, and environmental mitigation.

Summary: The study revealed that as grain yield increased, the spike number and grain number per spike of spring wheat linearly increased, while the 1000-kernel weight was not correlated with grain yield. In more recent genotypes, anthesis was initiated significantly earlier, although the length of the period from anthesis to maturity remained unchanged. As grain yield increased, both water use and Effective Use of Water (EUW) for aboveground biomass before anthesis decreased, and soil water content at anthesis was negatively correlated with aboveground biomass at anthesis, yet positively correlated with grain yield.

Summary: Heterosis, a common biological phenomenon in nature, significantly contributes to plant biomass and grain yield, with high economic returns in agricultural production. Recent research progress has focused on various aspects including classical genetics, genetic distance, QTLs, transcriptomes, proteomes, epigenetics, and hormone regulation, laying the foundation for in-depth study of its molecular and physiological aspects for increasing agricultural production yield.

Summary: The use of biofuels can help reduce greenhouse gas emissions, and studies have shown that transporting biomass in the form of water-based slurries through horizontal pipelines can significantly lower transportation costs. This study focuses on the frictional behavior of water-based chopped wheat straw slurry in a vertical pipeline, and found that the delivered concentrations for straw slurries and fine sand were close to their prepared concentrations, while there was a large discrepancy for medium-sized sand and glass beads slurries. Additionally, straw slurries showed drag-reducing capabilities in the mixed and turbulent flow regions at different velocities compared to horizontal flows.
