“…Data in Table 6 indicate that irrigation of artichoke plants with 75% ETc magnetized water produced the highest head weight of total yield in both seasons and irrigation with100% ETc magnetized water showed the largest head diameter with no significant differences with 75 % ETc magnetized water in the first season, however in the second season, irrigation with 75 % ETc magnetized water produced the highest head diameter with no significant differences with100% ETc magnetized water. These results are in harmony with Seron et al (2019) who revealed that irrigation with the 75% ETc provided fruit yield values equal to 100% ETc on eggplant. Also, irrigated artichoke plants with 100% ETc magnetized water produced the highest receptacle weight of total yield in both seasons Table 6.…”

“…Data in Table 3 show that in both seasons, plants that were irrigated with magnetic water at 100% ETc had the highest plant height values. Similar studies by (Seron et al, 2019, Samarah et al, 2020and Alattar et al, 2020 found positive effect of magnetic irrigation water on improving plant height of eggplant, tomato, and pepper respectively. Fertilizing globe artichoke plants with 75% of the recommended NPK provided the highest values of plant height in both seasons.…”

Two field experiments were carried out during the two growing seasons of 2019/2020 and 2020/2021 at the El Kanater Hort. Res. Station, El Kaloubia governorate Egypt, to study the effect of irrigation with normal water, magnetized water at 100, 75% of potential evapotranspiration, under different levels of N, P and K of the recommended doses fertilization and their combined interactions on productivity and water use efficiency of globe artichoke. The experiment design was a split plot with three replicates and the main plots were allocated to irrigation water treatments whereas the sub-plots were concerned with NPK fertilizer levels. The results indicate that irrigation with 75 or 100% ETc magnetic water produced the maximum vegetative growth, early and total yield / plant and ton/fed, head dry matter percent, inulin content, water use efficiency and head NPK percentages. The optimal NPK fertilizer rate for artichoke plants is 75% and irrigation with magnetized water at 75% ETc mixed with NPK fertilizers at 75% of recommended rates produced the best interaction of yield characters and its constituent. The highest water use efficiency (7.51 kg m-3 and 7.40 kg m-3 )) was obtained by 75% ETc magnetized mixed by100 or 75 % NPK as well as ETc 75% magnetized water combined with 75% of recommended NPK (9.21 kg m-3 ) in the first and second season respectively, It might be concluded that irrigated artichoke plants with 75% ETc magnetized water and fertilize with 75% of recommended NPK resulted in a 25% reduction in irrigation water and NPK fertilization.

“…Thus, as observed in this study, water deficit caused a restriction in eggplant yield, independently from the water treatment used, with lower values for the variables studied than the hydric supplementation with 100% ETc (Souza et al, 2019). Similar results of Souza et al (2019) were found by Seron et al (2019) for scarlet eggplant cultivation. The authors did not observe significant responses between the water treatment and the ETc levels evaluated.…”

The application of magnetically treated water is a valuable technique for crop irrigation to enhance the yield and quality of agricultural products. This study aims to evaluate the effect of irrigation water depths and the application of water with and without magnetic treatment on the yield and quality of bell pepper fruits in a controlled environment, verifying the effect of magnetically treated water on soil water retention. Two experiments were conducted in the Irrigation Technical Center of the Universidade Estadual de Maringá, Maringá/PR; the first on Summer 2017-2018, and the second on Winter-Spring 2018. A randomized block design with a factorial scheme 3 x 2 with four repetitions was used for the first experiment and a 2 x 2 scheme with six repetitions for the second. The first factor was the water replacement levels (based on the crop evapotranspiration), and the second the irrigation water treatment, with or without magnetic treatment. The yield and number of fruits were determined after six and four harvests in the first and second experiments. Quality characteristics (soluble solids level, pH, and titratable acidity) were evaluated from three fruits of each plant. The data was submitted to the Tukey test (p ≤ 0.05). It was verified that the application of magnetically treated water did not influence yield. However, it increased the levels of soluble solids and pH. To evaluate the effect of applying magnetically treated water on soil retention, 12 pots filled with soil and without plants were used. An increase in the gravimetric soil moisture using magnetically treated water was perceived, demonstrating higher water retention when using the irrigation method.

“…According to Seron et al (2019), the magneticallytreated water favored the development of scarlet eggplant, reducing the time for flowering and fruiting in the winter-spring season. However, for the plant height, stem diameter, and shoot dry matter, only the water replacement depth of 100% ETc obtained significant values.…”

This study aimed to evaluate the benefits of irrigation with magnetically-treated water and replacement depths based on ETc, in plant growth and development of bell pepper grown in a protected environment in two cultivation seasons. The experiment was carried out in a protected environment, in the Centro Técnico de Irrigação (CTI), at Universidade Estadual de Maringá (UEM), in Maringá - PR. Two experiments were performed: summer (2017-2018) and winter-spring (2018). The experimental design adopted was randomized blocks in factorial scheme 3 x 2 (six treatments) with four replications in the summer season and 2 x 2 (four treatments) with six replications in the winter-spring season. The first factor consisted of water replacement depths (50, 75 and 100% of the evapotranspiration of culture (ETc) in the summer season, and 75 and 100% ETc in the winter-spring season. The second factor was the application of water with and without magnetic treatment. Characteristics of growth (plant height, stem diameter, leaf area, and dry matter of stem, leaf, total, and root) and development (first flower and first fruit) were evaluated. Results showed that there was no significant interaction between the factors for the summer season. There were only isolated effects of replacement depths, and the 100% ETc had the highest values for the growth variables, independent of water treatment. The application of magnetically-treated water provided higher accumulation of dry matter (stem, total, and root) when irrigated with 75% ETc for the winter-spring season.
