EFFECT OF MAGNETIC WATER AND DEPTH OF DRIP IRRIGATION WATER AND YIELD OF CUCUMBER IN GREEN HOUSES .

Abstract

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 ) , sub- surface 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 .
