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: Research has shown that summer fallow sowing can improve the water use efficiency and grain yield of winter wheat. There are yearly differences in wheat yields based on crop management. A field experiment conducted over 8 years in the Loess Plateau revealed that high water consumption during early growth can increase spike number, grain number, and yield. Wide-space sowing and furrow sowing were beneficial for wheat yield when yields were intermediate or low. Soil water intake during specific growth stages also influenced tiller number, 1000-grain weight, and yield.

Summary: The 3-year cotton study in Maricopa, Arizona, USA showed significant differences between full irrigation and deficit irrigation treatments. The deficit irrigation treatment generally resulted in 21-23% less crop evapotranspiration compared to full irrigation, leading to cotton yield reductions of 15-36% in some years.

Summary: This study investigated the establishment of guayule crops using direct seeding and compared irrigation methods on different soil types. The results showed that water application significantly affected dry biomass, rubber yield, resin yield, and water productivity. Direct-seeded guayule in clay soils may benefit more from furrow irrigation due to lower rubber content and higher costs associated with subsurface drip irrigation.

Summary: Field stresses such as salinity and fertility stresses can increase stomatal resistance and affect evapotranspiration and plant water uptake. Accurate estimation of evapotranspiration and readily available water can improve irrigation scheduling accuracy, leading to reduced water use and water footprint.

Summary: The study revealed that soil above 60 cm is the main water consumption area while below is the main water storage area; the 80-100 cm layer responds to precipitation with a delay of 263 hours. Soil moisture fluctuations are closely correlated with potential and actual evapotranspiration.

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: The supply of water and nitrogen is crucial for facility agriculture. Farming practices that blindly use excessive irrigation and fertilization lead to reduced yields, lower quality, soil salinization, and fertility destruction. A two-year greenhouse experiment was conducted to study the effects of drip fertigation on fruit quality, yield, irrigation water use efficiency, and nitrogen use efficiency of greenhouse muskmelon in Southeast China.

Summary: This study compares global-scale patterns and drivers of leaf and ecosystem water use efficiency (WUE), revealing almost opposite trends in response to abiotic factors. Leaf intrinsic WUE is highest in arid regions and lowest in humid regions, while ecosystem WUE is lowest in arid regions and highest in humid regions. Phylogeny significantly affects leaf intrinsic WUE, while leaf area index is the most robust predictor of ecosystem WUE.

Summary: This study found that deep roots can increase soil water availability, regulate the timing of soil water use, and improve crop yield and water productivity. Deep root systems can also enhance leaf photosynthesis and prolong the duration of the greening period, resulting in higher crop yield and water productivity during the reproductive stage. An increase in the root:shoot ratio can increase yield, but excessively high root:shoot ratios can lead to a decrease in grain production per unit. Increasing rooting depth is an effective regulatory measure to increase soil water availability and optimize water consumption allocation, resulting in higher crop yield and water productivity.
