Summary: Saline water irrigation can help alleviate the shortage of freshwater resources in agriculture, but it may also lead to soil salinization and impact crop quality. The water-salt regulation (WSR) irrigation method can effectively avoid soil salinization and enhance the quality of tomatoes. The field experiment in the arid region of northwest China demonstrated that saline water irrigation can improve tomato quality while maintaining soil salinity balance. However, higher salinities of irrigation water resulted in decreased yield. It is important to maintain a balanced soil salinity level for sustainable production.

Summary: Managing saline water through desalination or blending with low salinity canal water is a viable strategy for potato irrigation in semi-arid regions. The study found that drip irrigation with saline groundwater resulted in a reduction in total tuber yield, while irrigation with mixed water increased yield. The use of 80% of recommended NPK was recommended to reduce costs and environmental pollution without any loss in tuber yield.

Summary: Strategies such as drip irrigation and alternate furrow irrigation can reduce water consumption and improve dry matter yield and irrigation water-use efficiency. Intercropping sorghum and amaranth at a ratio of 50:50 under drip irrigation resulted in the highest forage yield and irrigation water-use efficiency. Overall, the combination of drip irrigation and intercropping sorghum and amaranth at a ratio of 50:50 is a suitable strategy for improving forage yield and quality, as well as irrigation water-use efficiency.

Summary: This study aims to optimize irrigation for potato cultivated under drip irrigation. The AquaCrop model was used to simulate the growth and yield of potato, and it was found that the optimum irrigation schedule for potato is 20 mm of irrigation quota every 7 days, with yield starting to decline when the total irrigation exceeds 2500 m(3) ha(-1).

Summary: This study used an Eddy Covariance system to observe the water-carbon fluxes in cotton fields under mulched drip irrigation in an arid region. The ET was partitioned into transpiration (T) and evaporation (E) using the uWUE method, and the effects of environmental factors on each component were analyzed.

Summary: Drip irrigation systems can increase maize yield and water-nitrogen use efficiency in the Northeast Plain of China, with the best results observed in drip irrigation under plastic film mulch and biodegradable film mulch. Incorporating straw returning in drip irrigation can improve soil water and nitrate contents, maintaining higher physiological activity.

Summary: The study found that under drip irrigation, controlling soil matric potential below -30 kPa is beneficial for increasing maize leaf area index, specific leaf area, biomass, and yield. For each 1dS/m increase in soil ECe, maize yield decreases by 6.8%. Therefore, in this study, salt stress rather than water stress was identified as the key factor leading to reduced crop yield.

Summary: The study found that under the condition of irrigation at 3750 m3/hm2 and nitrogen application at 306.5 kg/hm2, maize plants showed optimal dry matter accumulation and yield performance, while increasing the irrigation level to 4500 m3/hm2 and nitrogen rate to 444.5 kg/hm2 resulted in decreased maize yield. The stepwise regression model for predicting maize yield revealed that GRavg had an extremely positive correlation with maize yield.

Summary: The optimal allocation of agricultural water and land resources is crucial for farmers' economic benefits, carbon sequestration, and water resource conservation. This study developed a novel water-carbon-economy coupling model and applied it to a real farm, demonstrating its effectiveness in achieving the optimal allocation of water and land resources. The model balances economic, environmental, and social benefits.
