In the Experimental Station of Irrigation and Drainage belonging to the IIRD, in Alquizar; it was carried out a study during several years that included the use of the magnetic treatment of the water like alternative of the irrigation under conditions of water deficit. The research was carried out on a Ferrallitic Red compacted soil, with the use of the water magnetically treated in the cultivation of tomato HC 3880 variety, garlic clone Vietnamese and the onion Red Creolle variety. For the magnetic treatment of the water (WMT), an electro magnetiser device of 3 diameter was used. It was determined the evapotranspiration and the crop coefficients for each case, as well as the yield parameters and crop quality comparing the irrigation applied with untreated water, with that of the magnetic treatment. Some foliar indicative was measured, as well as yield evaluation and crop quality.
The research showed WMT represents irrigation alternative for the environments with water shortage for horticultural crop as tomato, garlic and onion, since it regulate and reduce the crop evapotranspiration, aspect remarkable to consider in water regime, that also allows to decrease irrigations dosage in 17% (51.5mm) in tomato; 11% (51.4 mm) in garlic and 31% (117,5 mm) in onion, with an economic effect, favouring the production increase with 14, 15 and 11% respectively; saving water and increase of the efficiency in water use. The total water requirement was of 2.459, 4.309 y 3.276 m3/ha for the tomato, garlic and onion respectively.
