Summary: This study analysed the impact of different irrigation methods on greenhouse gas emissions in sugarcane cultivation. The results showed that irrigation with treated domestic sewage combined with N mineral fertilizers had the highest emissions of greenhouse gases, followed by irrigation with sewage only. These irrigation methods can enhance crop yield.

Summary: Sugarcane, a key agro-industrial crop in India, plays a pivotal role in the Indian economy. However, issues such as degradation of natural resources and over-exploitation of underground water pose challenges. By studying water-saving technologies, it is possible to increase sugarcane yield and enhance profitability for farmers.

Summary: Alternate partial root-zone drip fertigation (ADF) combines alternating irrigation and drip fertigation to save water, increase nitrogen (N) fertilizer efficiency, and improve tomato yield. Through a 2-year greenhouse experiment, the effect of different fertigation frequencies on soil moisture, nutrient distribution, and tomato yield under ADF was evaluated. The study found that a fertigation frequency of 6 days resulted in the highest tomato yield while maintaining water savings of 40%. This highlights the potential of ADF as a sustainable irrigation and fertigation technique.

Summary: This study evaluated the impact of drip fertigation on the growth and yield of okra, and found that it significantly increased yield compared to flood irrigation. The HYDRUS model was used to simulate irrigation scheduling and showed that drip irrigation resulted in more uniform soil moisture distribution compared to flood irrigation. Drip fertigation improved crop yields in different demonstration plots, with a range of benefits in terms of cost-effectiveness.

Summary: A 3-year field experiment was conducted to study the effects of subsurface drip irrigation (SDI) system combined with nitrogen management on crop yields, irrigation water productivity (WPi), nitrogen use efficiency (NUE) and profitability in a conservation agriculture-based (CA) maize-wheat system (MWS). The results showed that the SDI system with 100% recommended N significantly increased grain yields of maize, wheat, and MWS compared to conventional furrow/flood irrigation (CT-FI) system. The SDI system also showed higher water savings and WPi in all crops studied. Despite higher production costs, the net returns from MWS under SDI with 100% N were significantly higher than CT-FI system and increased even more with a subsidy on laying SDI system.

Summary: The study found that water-soluble phosphorus fertilizers and high saline water have significant impacts on the performance of the drip irrigation system, exacerbating emitter clogging issues. Urea phosphate performed better than mono-potassium phosphate in anti-clogging abilities, reducing chemical precipitations inside emitters. These results suggest that water salinity has a greater impact on emitter clogging than fertilizer types.

Summary: This study investigated the responses of fine root growth and morphology plasticity to drip irrigation and nitrogen fertigation in a young triploid P. tomentosa plantation. The results showed that fine roots had a conservative foraging strategy in water-and nitrogen-rich conditions, adapting to water-nitrogen heterogeneity.

Summary: Field experiments in arid region of Xinjiang, China, showed that adjusting irrigation amount and nitrogen levels can reduce soil salt accumulation, increase nitrogen uptake, and improve lint yield of cotton. Higher irrigation amount and nitrogen application rate resulted in significant increases in nitrogen uptake and water productivity.

Summary: The study aimed to determine the effects of different drip irrigation lateral spacings and nitrogen fertigation strategies on winter wheat growth, yield, and water use efficiency in the North China Plain. The experiment revealed that a drip irrigation lateral spacing of 40 cm and a nitrogen application mode of 25:75 significantly increased grain yield and water use efficiency compared to other settings. These findings provide valuable insights for the management of drip-irrigated winter wheat in the NCP.

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: The study indicated that real-time soil moisture-based irrigation significantly influenced the yield and water-use efficiency of green peas in semi-arid soils. Irrigation based on a soil matric potential threshold level of -30 kPa with 120% of recommended fertilizers dose resulted in maximum green pea pod yield and water-use efficiency.

Summary: The study found that irrigation pressures and filter types have a significant influence on emitter clogging in drip fertigation systems. Labyrinth emitters show better anti-clogging performance compared to flat emitters. An appropriate irrigation pressure combined with effective filters can reduce emitter clogging while saving water and fertilizer.

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: In soil column experiments, increasing irrigation leads to a larger decrease in soil pH, while nitrogen application significantly increases nitrogen content in the soil. Fertigation strategies have a significant impact on soil pH and nitrogen distribution, and selecting an appropriate strategy is crucial in reducing nitrogen leaching and preventing soil acidification.
