Summary: This study investigated the effects of different crop rotation sequences on soil water storage, crop yield, water use, and water productivity. The results showed that crop rotation had significant impacts on soil water content, crop yield, and water use efficiency. Wheat-potato-oil flax or potato-wheat-oil flax rotation increased oil flax grain yields, while wheat-oil flax-potato-oil flax improved oil flax water use efficiency.

Summary: This study investigated the drought response of two sugarcane cultivars and found that 'IACSP94-2094' exhibited better water use efficiency and carboxylation efficiency compared to 'IACSP97-7065'. RNA-seq analysis revealed differentially expressed genes related to photosynthesis, transcription factors, signal transduction, solute transport, and redox homeostasis. The drought-tolerant genotype also showed a robust antioxidant system. These findings provide valuable insights for sugarcane breeding programs and understanding the genetic basis of drought tolerance and water use efficiency improvement.

Summary: A field experiment was conducted to study the effects of different mulching treatments on the yield and water use efficiency of potato with different maturation characteristics. The results showed that straw mulch and plastic film mulch had significant effects on yield and water use efficiency. Straw mulch was more suitable for early-maturing varieties, while plastic film mulch was more suitable for late-maturing varieties.

Summary: Biochar is a commonly used soil amendment that has positive effects on improving soil quality, promoting resource efficiency of agricultural production, and reducing environmental pollution. The addition of biochar can significantly increase crop yield, water use efficiency, and nitrogen use efficiency. Key factors affecting the addition effect of biochar include soil organic carbon, soil total nitrogen, soil bulk density, biochar carbon content, and biochar carbon nitrogen ratio. Adding biochar with lower carbon content in soils with high bulk density and low nutrients can achieve a win-win situation in crop productivity and resource use efficiency.

Summary: This study investigated the effects of film mulching and soil wetted percentage on soil hydrothermal conditions and sweet potato growth. The results showed that film mulching significantly increased soil temperature, sweet potato yield, and water use efficiency. Black plastic mulching and transparent plastic mulching had positive effects on soil temperature and yield. Film mulching was found to be more important for sweet potato growth than irrigation.

Summary: Deficit irrigation (DI) is an effective technique to improve water use efficiency (WUE) in maize cultivation. A 3-year field experiment was conducted in Northeast China to investigate the combined effects of DI at the seedling stage and N fertilization on maize growth and yield. The results showed that DI positively impacted seedling growth and had similar or better effects on reproductive growth, grain yield, WUE, and NUE compared to well-watered plants. However, the effects of DI varied depending on the initial soil water content and precipitation. N fertilization compensated for the limited seedling growth under DI.

Summary: This study investigates the relationship between maize yield and evapotranspiration influenced by biochar and inorganic fertilizer. The results show that biochar application reduces the sensitivity of maize to water stress, and the combined application of biochar and inorganic fertilizer further decreases the sensitivity. Correlation analysis suggests that soil chemical properties are primarily responsible for the reduced sensitivity of maize yield to water stress.

Summary: Drought stress significantly limits soybean yields in Ontario, Canada. This study found that current commercial cultivars adapted to Ontario differ significantly in traits related to drought tolerance. Drought stress reduced seed yield by 51% on average, with pod number being the most affected yield component. Two drought-sensitive and three drought-tolerant cultivars were identified based on their seed yield ratio under drought stress to control conditions. Drought-tolerant cultivars maintained high values for water use, biomass accumulation, and pod number under drought stress.

Summary: The study investigated the impact of different sowing methods and nitrogen levels on dryland wheat yield, quality, and protein content. Wide-space sowing increased ears, yield production, and grain-filling rate, while furrow sowing prolonged grain filling duration and increased the number of spikes and 1000-grain weight. Drill sowing resulted in higher nitrogen content, protein content, and protein yield compared to wide-space sowing. Wide-precision sowing had higher grain yield and protein yield than trench sowing.

Summary: Forestal Arauco, a global manufacturer of forest products, conducted streamflow monitoring research in central-southern Chile between 35-39 degrees of latitude to improve understanding of the role of forest plantations on water balance. The research involved 10 small catchments with different forest types and utilized a combination of local rain gauges and data from the Chilean Directorate of Water for rainfall estimation.

Summary: Many communities in central Chile rely on water from small catchments in the coastal mountains, facing water security vulnerabilities in the summer dry season. The rate of decrease in stream flow after rain events is a key indicator of low flow risk, quantified using a recession coefficient (alpha). Differences in alpha values were observed between regions and forest types, especially in summer, highlighting the importance of understanding flow recession for water resources management in a changing climate.

Summary: The comparison of water use between plantations and alternative land uses in central Chile is crucial for natural resource management. The study found that plantations have higher transpiration rates compared to local native forests, mainly due to the higher transpiration rates of plantation species.

Summary: The origin of quarter-power scaling patterns has intrigued biologists and various models have been proposed to explain these patterns. However, discrepancies between model predictions and empirical data have hindered widespread acceptance. This study presents a new model that derives quarter-power scaling by preserving volume flow rate and velocity as model constraints. Applying this model to land plants, it predicts nonlinearity in allometric relationships and explains why scaling exponents covary along a fractal continuum. Data from various sources support the model's predictions and provide an alternative to current general models of plant metabolic allometry.

Summary: The impact of Eucalyptus plantations on water balance is believed to be more severe compared to commercial alternatives like Pinus species. However, only a few studies have directly compared the effects of Eucalyptus species and commercial alternatives on water balance. This paper presents a meta-analysis of published data and finds that, for a given climate wetness index, Eucalyptus and Pinus have similar annual water use. This study also highlights the correlation between soil depth and residuals for Eucalyptus, suggesting that the model overestimates or underestimates vegetation evaporation efficiency based on soil depth.

Summary: This study measured the water and flow in three streams before and after a wildfire in central Chile. It found that peak flows and baseflow increased in some catchments but decreased in others after the fire. However, there is currently no conclusive evidence of hydrological changes at the groundwater level due to wildfire.
