A field experiment was carried out in Al- Saqlawyah – Fallujah /Anbar Governorate during Fall season of 2017 in order to study three levels of water stress Depletion of 25% , 50% and 75% of available water and application of phosphorus and potassium levels in increasing availability nitrogen , phosphorus and potassium in soil and their absorbance by maize . The Farm was divided into three replication according to split plots arrangement in RCBD where water stress treatments Occupied the min plots. While fertilizers levels occupied the sub plots in the sub plots in three replications. The field experiment included giving the whole recommended amount of required fertilizers, the same recommended amount and adding phosphorus, Potassium only and adding phosphorus and potassium together. The results showed: The treatment of adding phosphorus and potassium to the recommended amount was superior in availability of Nitrogen in soil, while the treatment of adding phosphorus only our the recommended amount in the availability of Phosphorus in soil. The treatment of adding potassium to the recommended amount was superior in the availability of potassium in soil. The treatment of depletion 75% of available water gave the highest average of element availability in soil. The treatment of adding phosphorus and potassium our recommended amount was superior in Nitrogen , phosphorus and potassium absorption in vegetative part of plant. While treatment of 25% depletion of available water gave the highest average of absorbance of Nitrogen , phosphorus and potassium in vegetative part of plant. Generally, the application of fertilizers enhanced the performance of plant under water stress.

This experiment was conducted at the animal production farm of the Agriculture Research station (Ministry of Agriculture) from 3/9/2001 to 29/10/2001, 900 one day old broiler chicks (Fawbro) were used and distributed into 6 treatments (3 replicates / treatment, each repl. consist of 50 chicks), the chicks in the first treatment was the control treatment and the second treatment the chicks were exposed to heat stress at 38-43 Celsius for daily 6 hours from 4 to 8 weeks of age, the heat stress were companied with spraying Lactobacilli bacteria on chicks with rate of 0.2 ml per chick for supplying each of them 106 colony forming units (third treatment), while the fourth, fifth and sixth treatments the chicks gave potassium chloride and sodium bicarbonate salts at rate of 0.5% and vinegar at rate of 0.1% with drinking water campaigned with heat stress.
The results of the study revealed that sprayed chicks at first day of age with Lactobacilli bacteria could increase the ability of birds to face the effect of heat stress on relative weight of carcass yields especially breast yield which the relative weight of it increased significantly in the this treatment, also, using probiotic could help for obtaining more lean tissue from carcass yield with decreasing the other component (bone, skin and fat) comparing with the other treatments.
