Title: Effect of magnetic water on growth, yield and quality of groundnut infected with root-knot nematode (Meloidogyne arenaria) in sandy soil
Abstract: Magnetic treatment is considered one of uncommon factor which has positive effects on yield of many crops.Two field trials using ground nut (var.Giza-6) were conducted at National Research Centre Experimental Station, Alimam Malek village, Al Nubaria district, Al Behaira Governorate, Egypt in 2014 and 2015 summer seasons to study and evaluate the effects of magnetizing irrigation water on growth, yield and quality of groundnut naturally infected with root-knot nematode (Meloidogyne arenaria) in sandy soil.Results indicated that, irrigation peanut plants with water passed through magnetic device (4 inch, production by Magnetic Technologies L.C.C., Russia, branch United Arab Emirates) induced positive significant effect on the most of studied parameters.The percentage improvement ranged between 5.10 to 43.05% in yield components.As well as, the increases reached to 30.38 and 29.46% in pods and seeds yield per hectar.Results also indicated that the nematode infection (root galling) was not significantly affected by magnetic water, while the number of the juveniles (J 2 ) in soil at harvest (first nematode generation ) significantly increased in magntic water treatment compared with that in normal water.
