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 (J2) in soil at harvest (first
nematode generation ) significantly increased in magntic water treatment compared
with that in normal water.
