“…Table 3 also indicates that there was no significant difference in the TSS, VC, SSC, TA, and SAR at different nitrogen levels and the same soil salt content (p > 0.05). However, these indicators were greatly affected by salt, i.e., that TSS, VC, SSC, and TA increased when soil salt was more abundant, confirming the results of other studies [37][38][39][40]. Whereas SAR was elevated under low salt conditions at different N levels, and the maximum value was in the S1 treatment.…”

Xinjiang is one of the most prolific tomato-planting areas in China. Here, we carried out a two-year (2017–2018) field experiment in Xinjiang to study the effects of different nitrogen (N) application rates on the spatial distribution of water and salt in the root zone, as well as their impacts on the yield and quality of tomatoes under mulched drip irrigation. The ideal ranges of N application rates for tomato yield and quality were examined under different salinity levels. Results indicated that soil water content and salinity increased with soil depth. Soil water content was closely related to soil salinity but not to N. Among the tested application rates, tomato yield was highest under the medium-high N (225–300 kg/ha) and low salt (4 g/kg) treatment. Under the highest salt level (10 g/kg), the low nitrogen treatment (150 kg/ha) was better than the high N treatment (300 kg/ha) at boosting tomato yield. Moreover, we found that salinity had a stronger effect on tomato quality than N. Based on these results, we were able to recommend ideal ranges for N (155–201 kg/ha) and salt (3.56–5.59 g/kg) while both are present in the soil.

“…Reduced total and marketable fruit yield with increasing salinity level was a consequence of reduction in fruit fresh weight ( Table 2). [16][17][18] reported that, the numbers of fruits was not affected by moderate salinity, and the yield reduction was entirely due to smaller fruit. Others found that, the number of harvested fruit per plant reduced with salinity [19][20][21].…”

A field study was conducted on the experimental farm of ministry of agriculture, located at Palestine Technical University-Kadoorie, to investigate the effects of saline water irrigation through three irrigation intervals on yield of tomato crop and soil properties. The land was prepared and divided into 12 treatments, each of 48 square meters on the first of April. Tomato seedlings were planted on 25 April 2010; the seedlings were irrigated with fresh water for a period of 10 days after planting. Three levels of saline water irrigation (3, 5, 7 dS/m) plus fresh water as control were applied during the growing season. The four irrigation water treatments were applied through three irrigation intervals (every day, every second day and every three days). Gravimetric soil moisture content and soil electrical conductivity were monitored every two weeks during the growing period. Yield measurements were taken for total fruit yield, marketable yield as a percent of total yield, and average fruit weight of each treatment. Results of this study indicated that, plant treatments irrigated with saline water gave the highest yield for treatments irrigated every day compared to the treatments irrigated every second day and every three days. Statistical analysis showed significant differences in yield reduction between every second day and every three days irrigation intervals under 5 and 7 dS/m saline irrigation levels, while there was no significant difference between irrigation intervals under 3 dS/m salinity level.

“…This decrease is referred to the transfer of inorganic acids under saline stress to fruits, especially cations, which leads to an increase in the ratio of cation to anion in the tomato fruits. This increase causes the increase of total acidity which induces the reduction of pH value [36][37][38][39][40][41]. The data obtained showed that irrigation with TW resulted in decrease in pH value in the tomato fruits than the UW.…”

Magnetic water treatment is considered as one of many techniques used worldwide that affects plant growth and development. This study examines whether there are beneficial effects of magnetic treatment of irrigation water on yield and water productivity as well as water saving. Three experiments were performed involving three crops (eggplant, faba beans and tomato) with different salinity tolerance thresholds EC w 0.7, 1.1 and 1.7 dS/m, respectively. Two types of irrigation water were applied magnetically treated and non-magnetically treated. The experiments were carried out at Wadi EL Natroon station of Water Management Research Institute, El-Behira Governorate, Egypt during two sequentially winter seasons of 2015/2016 and 2016/2017 in a complete randomized design analysis with four replicates. There was a decrease of pH of the soil irrigated with magnetically treated water (MTW) compared with the non-MTW. The pH reached neutral values in some locations, especially the area cultivated with the faba beans (pH between 7.05 and 7.08). Results showed significant increases of water productivity for the MTW compared with non-MTW equal to 1.65, 1.88 and 1.78 for eggplant, faba beans and tomato, respectively. It was also observed that the MTW affected the amounts of irrigation water added to different crops during its growing period. The percentages of water savings were 11%, 13.5% and 14.2% for eggplant, faba beans and tomato, respectively. As a result the net return increased by 1.97, 3.0 and 2.45 for the three crops, respectively.
