Abstract:
In order to study the effect of Magnetic Water and Seed on yield and yield component of maize (SC704) under drought stress condition, a field experiment was carried out in 2009, in Islamic Azad University of Karaj Iran, by using split plot in randomize complete block design with four replications under two separate conditions of irrigation type: Magnetic (MI1) and normal (MI0) irrigation, also Irrigation regime treatments in 3 levels %40 (IR0); 60% (IR1); %75 (IR2) of water depletion, in main plot and seed treatments in 2 levels, magnetic seed (MS1) and non magnetic (MS0) in subplot. The result showed that with increasing of drought stress intensity traits of harvest index, grain yield, biomass, ear weight, seed weight per ear, ear diameter, row number per ear, seed number per row and seed number per ear decreased and part of non inoculated ear length increased. Irrigation water magnetized caused increase of traits such as harvest index, grain yield, plant height, ear weight, seed weight per ear, ear diameter, row number per ear, seed number per row and diameter of plant and part of non inoculated ear length. Interaction effects of irrigation regimes and drought stress were significant on traits of row number per ear and seed number per ear. Interaction effects of drought stress and seed treatments on traits of seed number per ear and part of non inoculated ear length were significant. Interaction effect of irrigation regimes, drought stress and seed treatment on traits of harvest index and grain yield was significant. In magnetized water treatments had positive correlation between grain yield with harvest index (r=0.96*), ear weight (r=0.98**) and under normal irrigation condition, have positive correlation between grain yield with gravest index (r=0.98**), row number per ear (r=0.89**), ear weight (r=0.84**) and biomass (r = 0.79**). In normal irrigation (A1) had positive correlation between grain yield and harvest index (r=0.66**) but with 1000 seed weight had negative correlation (r=-0.53**). In intensive stress condition (A3) had positive correlation between harvest index (r=0.98**), row number per ear (r=0.7**), plant height (r=0.67**), ear weight (r=0.66**).
