The experiment was conducted in the green house of the College of
Agriculture , University of Diyala for the season 2009 – 2010 on sandy
loam soil . RCBD system was applied with three replications . The
experiment included two water factors , magnetic and non-magnetic water ,
and four depth of water applications (surface drip irrigation (D0) , subsurface
at depth of 5 , 10 ,and15 cm namely D5 , D10 , and D15 ,
respectively . Polyethylene pipes of 5cm in diameter were used to
produced different length of pipes which located near each plant under
the dripper . Magnetic device of 1500 gauss was used to produce
magnetized water.
The results explained that there is a highly significant differences by
using magnetic water for all treatments in growth Parameters ( plant
height , leaf area , dry root weight ,vegetative dry weight) and yield as
compared with non-magnetic water. The depth of water application at 5 cm
(D0) was highly significant in all growth parameters as compared with
other depth of water applications. The highest value of plant height , leaf
area , vegetative dry weight , and dry root weight at D5 and magnetic
water treatments are 146.33 cm , 9472.66 cm2/plant , 98.48gm/plant, and 4.4
gm/plant , respectively . The highest value of total yield at the D5 with
magnetic water treatment is 27.61 ton/ha as compared with 20.21 ton/ha
at D15 treatment . |
