Abstract

A biological Pots experiment was conducted in lath house of soil and water sci.Dept. using silty clay loam Typic Torrifluvent soil collected form Agriculture College fields. The soil was fertilized by 240 kg N.ha-1 as Urea fertilizer ,75 kg P.ha-1 as super phosphate and 120 kg K.ha-1 as Potassium sulphate fertilize. Corn seeds were planted in spring 2007 irrigated by tap water with electrical conductivity of 0.4 dS.m-1 and drainage saline water 7.4 ds.m-1 with and without magnetic . 10 Weeks after planting , plants were harvested, hights and dry weight of shoots were measured also total uptake of N,P and K nutrients were measured .
The results of this experiment showed that Corn Plants hight ,dry weights ,total uptake of N,P and K nutrients were significantly decreased when drainage saline water used as campared with tap water with decreament 10.8 ,28.9 ,17.7 ,22.7 ,17.8 % of these characters respectively. On other hand magnetic water significantly increased all studied characters as compared with non-magnetic. The increase were 17.7 ,34.6 ,23.8 ,28.4 ,21.9 % for plant hight , dry matter weight ,total uptake of N ,P and K nutrients respectively. The results also indicated that there was a significant interaction between water quality and magnetic water , The highst values were obtined with magnetic tap water treatment with no significant differences between magnetic saline drainage water and non-magnetic tap water.
