| Abstract | ||
| This study deals with a prospect using different levels of waste water from the heavy – water treatment plant in Rustumiya Baghdad for irrigation purpose and their effects on growth and yield of corn (zea mays L.), with some chemical properties of soil, such as ECe , pH , and total Fe,Mn,Zn,Cu,Pb, Cd in soil and plant. Three levels of waste water (0,50,and 100%) have been used at two stages, without fertilizer. (320 kg N.h-1 with 80 kg P.h-1) for the control treatment, and the second is with chemical fertilizer (160 kg N.h-1 with 40 kg P.h-1) for two levels (50,100%) of waste water. Seeds of zea mays L. are planted in plastic pots of 12 kg capacity. CRD with three replicates has been used. Results have showed a significant increases in the electrical conductivity and pH of soil at both levels (%50,100) applied, as compared with control treatment. Whereas the high level of Applying (%100) has given a significant increasing in the electrical conductivity and pH is compared with tow levels (%50) of waste water applied. Also results have indicated a significant increasing in all heavy metals studied in soil and plant for both treatments of comparing with the control treatment , and this increase continues with increased level of waste water applied. Never the less, all heavy metals studied are in minimal enrichment of pollution according to contamination parameters (EF,CF,and PLI) used in this study , and have been suggested by many recent pollution studies. Results showed a significant increased in the plant length and dry weight of plant for all treatments comparing with the control treatment. Also the tow levels (%50) of waste water applied with half amount of chemical fertilizer has given a significant increasing in plant length and dry weight of the plant. | ||
