The study was conducted at the College of Agriculture-University of Anbar during the autumn of 2013 to study the effect of treated sewage effluent by decomposed hay waste and Rock phosphate on growth of Barley. The study included four quality of irrigation water (w): fresh water (w1) sewage effluent treated by decomposed hay waste (w2), treated by Rock phosphate (w3) and untreated sewage effluent (w4). Second factor is poultry manure levels: (O0) no added, (O1) 10 mt ha-1 , (O2) 20 mt ha-1, (O3) 30 mt ha-1 with three replication using (RCBD). At end of the experiment, dry weight and plant heights were measured, in addition to concentrations of Fe, Zn, Mn, Cu, Cd and Pb for Barley seeds.
Results showed a significant increase in shoot dry weight and plant heights with treated sewage by decomposed hay waste and Rock phosphate with values 50.44, 46.70 gm and 54.0, 50.58 cm respectively compared with fresh water and untreated water and increase in shoot dry weight and plant heights with levels of poultry manure. Fe, Zn, Mn, Cu, Cd, Pb concentrations decrease in Barley seeds with irrigated sewage treated by decomposed hay waste and treated by Rock phosphate, with 41.35, 31.0, 11.09, 1.31, 0.275, 0.621 mg kg-1 and 40.84, 29.5, 10.95, 1.30, 0.295, 0.635 mg.kg-1respectively. Compared with untreated sewage water and increasing of poultry manure levels resulted in increase of Fe, Zn, Mn, Cu concentration in Barley seeds giving 43.34, 33.40, 11.75, 1.63 mg kg-1 respectively compared with control , while concentration Cd, Pb decrease with poultry manure addition.

The experiment was conducted during spring season 2016 in two type's soils textures, the first one was held in college of agriculture-Baghdad University (abu-Grhaib) which is silty clay loam, The second texture of soil was silty loam. The purpose is to study the effect addition for different levels of organic matter in some infiltration rate and basic infiltration rate, the experiment includes two factors; first factor includes two levels for organic matter, addition 20 tan. ha-1 L1, 40tan. ha.-1 L2 and control treatment L0 (without organic matter), the other factor includes two texture of soil , Silty clay loam T1 and silty loam T2, these levels of organic matter was mixed of the surface soil until the depth 0.75m before measuring the infiltration.
The results showed that values of accumulative infiltration were increased at 18.80, 23.00% by addition of highest levels of organic matter to the silty clay loam soil and silty loam soil, respectively. The values of infiltration rate were increased up to 31.97, 34.74% for the two texture of soil silty clay loam and silty loam, respectively. The values of basic infiltration rate were increased up to 18.00, 31.82% by addition of the highest level of organic matter to the two textures of soils silty clay loam and silty loam, respectively.

This experiment was conducted in Al-Anbar university – College of Science. during autum season 2004, to study the effects of water stress and organic matter on yield, Consumptive water use and water efficiency of sorghum plant. The experiment included the following treatment:
1- Soil water stress(soil moisture tension) with three percentages 25, 50 and 75% of water availability.
2- Organic matter from aquatic plant with levels 0.000 , 250 and 500 gm - vase.
3- Soil type: tow soils were used with different textures.
Factorial experiment was used according to completely randomized design (C.R.D.) with three replicates for each treatment. Plastic containers were used (capacity of 8 kg) with dried. And filled with sieved soils. Seeds of sorghum were planted on July - 2nd - 2004. Irrigation was done according to volumetric method to protect soil moisture stresses of the water availability percentage 25, 50 and 75%. The study continued up to December - 15th - 2004. The usage of water consumption by sorghum was calculated according to quantities of water applied for whole the period of growth season. Yield was harvested on December - 30th - 2004. Measured, also yield of seeds, water consumption and water use efficiency. The result can be summarized as follows:-
1- The yield of sorghum seed was affected significantly by changing water stress and organic matter. The interference between water deficit 25% with 250 gm - vase organic matter gave a highest yield 30.6 gm - vase (4377 kg - hec) and 43.77 gm - vase (6189 kg - hec) for the two soils, Sandy loam and clay loam respectively. The treatment water deficit 75% and zero organic matter had lower yield.
2- Water stress and organic matter were affected significantly on water consumption for sorghum. Water consumption decreased with increasing in percentage of moisture deficit, and by adding organic matter. The lower value of water consumption was in a treatment of 75%, with the water deficit 250 gm organic matter, 60.46 and 51.44 L - vase for sandy loam soil and clay loam soil.
3- Increasing in water stress caused a decrease in water efficiency values. While addition of organic matter caused on increase in water efficiency. The highest values of water efficiency was achieved by treatment of 25% water deficit with the 250 gm organic matter. Water efficiency was 0.446 and 0.729 kg - m3 for sandy loam and clay loam soils respectively. The lowest values of water use efficiency were in treatment of 75% water deficit with out organic matter for the tow soils.
4- Clay loam soil was recognized as compared with the sandy loam soil by increase yield, and less water consumption highest water use efficiency.
