This study has been carried out to evaluate the effect of using oils of some kinds of spices (garlic, black seed, corn &mint) on prolonging the preservation period of soft white cheese. Two pieces of soft white cheese have been purchased from Al Batool Company and distributed on five treatments(control, garlic, black seed, corn and mint).Samples of cheese are coated by oils of the spices and then stored in refrigerator for different periods (1,3,6,9,12) days. During these periods done evaluation of sensory characters for cheese (color, flavor, texture, bitterness,) to all treatments and the results were analyzed statistically.
The results which have been obtained show that garlic treatment exceeds other treatments in keeping sensory characters. Black seed and corn treatments come in the second rank. The results also reveal that a significant(P<0.05)superior of garlic and black seed treatment as compared to other treatments in keeping the chemical composition of cheese (PH, moisture, acidity nitrogen, VFA).The inhibitory effect of garlic and black seed is obvious and significantly P<0.05)on microorganism, particularly total count bacteria, which is(21×103 and 30×101) cfu/g respectively for garlic treatment Vs (47×103 and 38×101) cfu/g for black seed .Generally the results show that possibility of using oils of spices as preservative materials, because they are able to increases the preservation period of soft cheese for 12 days. While samples of control, exposed to many changes in all studied characters when store for the same period.

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.
