Abstract

This study was carried out in a plastic pots to show the effect of five typs of ground water in Rutba City in growth and nutrient contents of corn (Zeamays L.) the electric conductivity of water was 1.09,2.4 , 3.5 , 4.6 , 6.2 ds-m-1 respectively. ineach pot add 5Kg of silty loam soil was with 200 Kg N.h-1 Urea and 120Kg P2O5.h-1 Super phosphate and 60 Kg K2O.h-1 Potassium
Sulphate as Fertilizer. Complete Randomized design (CRD) was Used with Four replicates . The Corn Plants were harvested in the Flowering Stage after Plants heights were measured .weight of dry matter of vegetative parts and roots were calculated . The Uptake of Ca, Mg, N, P, K, Na also estimated-The results Showed:
1. Significant decrease in the plant Length , dry weight of the vegetative and roots with increase of water Salinity For each treatment except the Second treatment So we recommend to use the Second treatment in Case of Fresh water shortage .
2. Significant in Crease in the Uptake of Ca, Mg , P and Non-Significantincrease in Uptake K, Na and Significant decrease of N with the in Crease of water Salinity.
