Rationalization of Water Use and Fertilization of Globe Artichoke Using Magnetic Water Irrigation

Abstract

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.

The Impact of Irrigation Levels with Normal and Magnetic Water, Bio Fertilization on Garlic Growth, Yield and Storage

“…magnetic water revealed the highest levels of water productivity in comparison to the other treatments. These findings are consistent with those of Ismail et al (2022), where showed that globe artichokes irrigated with 75 or 100% ETc. magnetic water during drought stress generated the highest efficiency of water use.…”

“…Additionally, magnetic water might stimulate the production of proteins, rates of photosynthesis, and pigments considerably which could contribute to an increase in garlic yield (Mostafa 2020). Similar results were obtained by Ismail et al (2022), that noticed a significant increase in artichoke yield ton/fed when they used magnetic water to irrigate the plants at either 75 or 100% ETc. Moreover, As stated by Faridvand et al (2021), applying magnetic water treatment substantially improved the yield of fennel seeds.…”

“…Application of water that is magnetic results in increased plant resistance to water stress, indicating that its effectiveness is connected to enhancing the antioxidant system and lowering oxidative damage of globe artichoke leaves Bagherifard and Ghasemnezhad (2014). Also, result was in harmony with Ismail et al (2022) where they showed that the highest vegetative growth of globe artichoke was achieved with irrigation using either 75% or 100% ETc. magnetic water.…”

“…magnetic water produced the highest dry matter percentage. In this respect, Ismail et al (2022), globe artichokes exhibited the highest dry matter when irrigated with either 75% or 100% ETc. magnetic water.…”

Evaluations of drip and furrow irrigation method under deficit irrigation for pepper productivity in Northwest Ethiopia

“…However, hot pepper is particularly vulnerable to drought stress due to its wide range of transpiring leaf surfaces and high stomatal conductance, as well as its shallow root system (Zayzay Jr, 2015;Agliassa et al, 2021). To ensure high yields and su cient water supply, moist soil is required throughout the growing season (Ismail and Ozawa, 2009;Agliassa et al, 2021). Hot pepper cultivation is prevalent in warm and semi-arid countries, including Ethiopia, where it is a high-value cash crop used in many ways (Dorji et al, 2005; Adametie and Mitku, 2021).…”
