Summary: This study investigated the influence of irrigation water salinity and sodium-calcium molar concentration ratio on tomato cultivation. It found that higher salinity and lower sodium-calcium molar concentration ratio in irrigation water positively affected root water uptake and average fruit weight, while lower salinity and higher molar concentration ratio positively affected tomato yield and fruit quality.

Summary: The study aimed to investigate the impact of irrigation frequency and amount on root characteristics of drip-irrigated spring wheat and their relationship with aboveground biomass and yield. Results showed varying root characteristics with different irrigation intervals and amounts, highlighting the importance of optimum irrigation for improving wheat root length, weight, biomass accumulation, and ultimately yield and water use efficiency.

Summary: Cotton is widely used in various industries but faces threats from soil salinization. Drip irrigation plays a crucial role in improving water and fertilization efficiency. Accurate prediction of soil salinity and crop evapotranspiration is important for water management in arid and saline regions. We proposed a method based on machine learning to simulate soil salinity, evapotranspiration, and cotton yield using a global dataset.

Summary: Soil moisture availability significantly affects the yield and quality of crop plants, especially in arid climates where irrigation is crucial. This two-year study on silage maize showed that different irrigation levels and intervals can alter the yield, quality, and water use efficiency of the crops. Frequent irrigations increased silage yield, while low water application led to decreased yield under arid climatic conditions.

Summary: In addition to water scarcity, the sustainable development of agriculture in arid and semi-arid regions of China is also constrained by soil salinization. This study aimed to investigate the spatial distribution and variability of soil salinity in drip-irrigated cotton fields under different irrigation levels in northwest China. The results showed that irrigation amount significantly influenced the distribution of soil salinity, with increased irrigation reducing total dissolved solids (TDS) in the soil but increasing the area of the desalination zone and the depth of salt accumulation. The variability of soil salinity was affected by irrigation amount, growth stage, and soil depth, with the largest spatial variability occurring in the middle growth stage of cotton.

Summary: This study aimed to investigate the effects of subsurface drainage spacing on soil salinity and groundwater level. The results showed that subsurface drainage reduced soil salinity and effectively controlled the groundwater table. Decreasing the drain spacing further enhanced these effects.

Summary: Soil secondary salinization in the Yellow River Diversion Irrigation Area of Northwest China seriously threatens local agricultural production. Drip irrigation technology, with precise control of irrigation water volume and flow, significantly reduces surface evaporation and subsurface leakage of water, improves water use efficiency, and increases grain yield. It also forms a desalination zone in the soil under drip irrigation, gradually transforming the soil from surface aggregation type to the bottom accumulation type. Drip irrigation with an appropriate irrigation volume in the saline land in northern Ningxia can improve water saving, salt suppression, and maize yield.

Summary: This study aimed to investigate the effects of irrigation water salinity on water use, growth, physiology, and yield parameters of drip-irrigated tomatoes in two different growing seasons. The results showed that increased water salinities caused an increase in soil salinity and a decrease in seasonal crop evapotranspiration. Marketable and total tomato yields, and the leaf area index showed significant decreases under increased salinities in both seasons. The slope value and threshold value of salinity should be considered for decision making in tomato production at different growing seasons.

Summary: The study investigates the effect of soil water content threshold levels on kiwifruit quality at different growth stages. The results suggest that specific threshold levels of soil water content significantly impact fruit weight, volume, and chemical quality. In particular, certain threshold levels enhance the nutritional value, taste, and storage capability of kiwifruits.

Summary: Drip irrigation has been widely implemented in arid agricultural regions to mitigate water shortage and improve water productivity. It was found that drip irrigation increased yield and water productivity, while decreasing leaf area index. The promotion of root development and increase in soil temperature were key factors contributing to the improved crop activity.

Summary: Water use efficiency (WUE) is a crucial indicator for evaluating the balance between crop water demand and artificial water input in irrigation management. Accurately evaluating the WUE of plants in enlarged lateral space (ELS) drip irrigation wheat systems is of great importance. The study compared different methods of calculating WUE and found that modified ELS patterns effectively reduced heterogeneity in WUE between rows, resulting in increased overall yield and WUE. The study recommends TR6S as the optimal ELS drip irrigation pattern and suggests that WUE13 C is a suitable indicator for reflecting WUE in different rows of ELS patterns.
