Summary: This study examined the effects of nitrogen supply on tomato yield, WUE, and fruit quality through a global meta-analysis. The optimal nitrogen rate was found to significantly increase tomato yield and improve fruit quality indicators such as Vitamin C, sugar/acid ratio, soluble sugar, and total soluble solids. The study also analyzed the impact of factors like soil pH and average annual temperature on tomato production.

Summary: The over-application of irrigation and chemical fertilization in the greenhouse vegetable production system in China can have negative impacts on fruit quality, economic profit, and resource utilization. This study investigated the effects of different irrigation levels and fertilization practices on tomato yield, fruit quality, economic benefit, water use efficiency, and nitrogen use efficiency. The results showed that the combination of both soluble organic and chemical fertilizers for topdressing obtained the highest plant nitrogen uptake, net profit, and water use efficiency, and significantly improved tomato yield. The addition of organic fertilizers also reduced nitrate content in tomato fruits. Deficit irrigation promoted a higher water use efficiency compared to conventional fertilization practice. According to the principal component analysis, the fertilization practice with soluble organic and chemical fertilizers was ranked first regardless of irrigation levels and growing seasons.

Summary: The study evaluated the impact of irrigation and nitrogen levels on African eggplant, showing that optimal irrigation for the crop is around 80% of total water requirement and nitrogen application at 75%. Plant growth variables had a good correlation with fruit yield, indicating that monitoring growth variables can help assess yield.

Summary: This study conducted experiments on the irrigation scheduling of tomato crops and found that water doses had a significant impact on fruit quality and production, while irrigation frequency had a smaller effect. It is recommended to use 100% of the potential evapotranspiration, with irrigation once per day, to achieve a balance between production, fruit quality, and water use efficiency.

Summary: This study investigated the effects of surface drip irrigation (SDI) and shallow subsurface drip irrigation (SSDI), as well as different ET-based irrigation scheduling methods, on the grain yield, water use efficiency (WUE), and yield response factor (Ky) of maize. The results showed that SSDI was preferred over SDI, and reference evapotranspiration (ETo) was the most suitable method for assessing maize evapotranspiration. Maize in the region exhibited moderate tolerance to water stress. These findings are significant for precise planning and efficient irrigation of maize in the area.

Summary: Field experiments were conducted to study the response of tomatoes to different water salinity levels under drip irrigation in coastal semi-humid areas and arid areas in China. The results showed that salinity hindered tomato yield but improved fruit quality. The salinity threshold for tomato yield without reduction was 1.8 dS/m in semi-humid area and 2.1 dS/m in arid area. From a comprehensive perspective of water saving, avoiding yield reduction, and improving fruit quality, a saline water of about 6.3 dS/m and 4.9 dS/m is suggested for drip irrigation of tomatoes in semi-humid areas and arid areas in China.

Summary: The study found that converting from furrow to drip irrigation in a greenhouse in arid Northwest China is beneficial for increasing the accumulation of phytochemicals and antioxidant activity in tomato fruits. However, in summer, this conversion led to a significant reduction in tomato yield. Meanwhile, in winter, drip irrigation enhanced the nutritional yield and water productivity of tomatoes.

Summary: The scarcity of freshwater resources hinders sustainable agriculture, particularly tomato production. Salty water irrigation is a promising solution for alleviating freshwater scarcity, but its effects on tomato yield, irrigation water use efficiency (IWUE), and fruit quality are unclear. A meta-analysis of 1230 data pairs from 56 research papers revealed that salty water irrigation significantly decreased tomato yield and IWUE, while increasing total soluble solids, organic acids, sugar and acid ratio, and vitamin C compared to freshwater irrigation. Brackish and moderately saline water were recommended for maintaining yield and quality. Soil organic matter could mitigate the negative effects of salty water irrigation. A win-win analysis suggested the suitability of brackish and moderately saline water for drip irrigation and alkaline soils.

Summary: Biodegradable mulches have the same temperature- and moisture-preservation effects as ordinary plastic mulches before degradation. After degradation, rainwater enters the soil through the damaged parts, improving precipitation utilization. The study found that the effective infiltration of precipitation decreases and then increases with increasing precipitation, and the effective infiltration ratio of precipitation increases as the damage to the biodegradable film increases under the same precipitation intensity.

Summary: The research found that with increasing irrigation amount, aboveground biomass, leaf area index, plant height, and fruit yield all increased. However, the lowest levels of soluble solids, vitamin C, and soluble sugar in tomato fruits were found under the W1 irrigation regime. Deficit drip irrigation has the potential to support tomato growth, improve marketable yield and water use efficiency.

Summary: By comparing two irrigation systems (conventional design and larger wetted surface design), it was found that the larger wetted surface design promoted better distribution of water and fertilisers in the soil, improving gas-exchange parameters and reducing the number of fruits affected by endoxerosis. The system also advanced the first harvest time and increased economic water productivity for early lemon tree growers.

Summary: Unreasonable irrigation and nitrogen application can negatively impact tomato yield and resource utilization. This study investigated the effects of water conservation and nitrogen reduction on tomato production and identified the optimal water and nitrogen supply patterns. The findings have implications for promoting sustainable greenhouse tomato production in Northeast China.

Summary: Film-mulching drip irrigation can increase crop yield and water use efficiency. Its effectiveness is influenced by factors such as climate, soil, crop type, water consumption, and mulching material. It is most effective in areas with low temperature and rainfall, and in medium-textured soil with low available water capacity. The improvement effect decreases as water consumption increases.
