Abstract: The research aims to identify some of the effects of fiscal and monetary policies in the value of agricultural output in selected Arab countries during the period (1990-2010). It has become necessary to know the role of fiscal and monetary policies tools applied during the study period, and its objectives towards the agricultural sector in the countries of the research sample. So the research presumer to know a number of factors affecting the value of agricultural output, to present these factors are: (inflation , the size of agricultural loans, surplus or budget deficit, the exchange rate), was the search explore know the effect of these factors on the value of agricultural output in Iraq and Egypt during the period (1990-2010) and the comparison between the two, so the search method depends on two main aspects: first, the descriptive side which was based on previous studies , who studied the same subject, and secondly, the quantitative aspect, which is based on the multiple linear regression model, and then interpret the results of the quantitative aspect to assess the practical side of the study. It also included research on the most important conclusions was including: the impact of fiscal and monetary policies in Iraq were limited due to economic conditions experienced by Iraq in the nineties and after the year (2003 ), which were not clear and dramatically reverse of what it was in Egypt, Accordingly, the research recommends: the use of fiscal and monetary policies more clearly by lawmakers and the need for state intervention in the formulation of these policies in an integrated manner to improve the performance of the economy and accelerate development and which are reflected directly in upgrading the performance of sectors , including the agricultural sector.
Abstract: The research aims to identify the most important factors affecting the total value of agricultural GDP of Iraq and neighboring Arab countries (Syria, Jordan and Saudi Arabia) to grasp the relative importance of these factors during the period (1980-2010). The research depended on a hypothesis that there are a number of economic factors that vary in impact in the value of agricultural output in Iraq and its neighboring Arab countries for the period (1980-2010), and that there is a variation in the impact of these factors between Iraq and these countries. In order to prove the hypothesis of this search a number of economic factors that vary in their impact on the value of agricultural GDP and of (b crop area planted, the number of agricultural workers, agricultural tractors, combine harvesters agricultural, fertilizer, chemical, agricultural loans, farm subsidies, the exchange rate) had been selected the data had been used from those for time - series variables standing thirty -one-year– old. To get the best results has been used principal components analysis had been used. The research found a number of conclusions and recommendations in order to increase the value of agricultural GDP sample countries.

Abstract: ABSTRACT The research aims to study and measure the impact of trade policies on the growth of agricultural output in some Arab countries, namely, (Iraq. Saudi Arabia) and adopted on the search a premise that the policies of trade hav different effects of varying the rate of financing agricultural output in the countries of the search sample, also adopted a search on the descriptive approach with the analysis quantification using multiple regression analysis. The search included a range of time series Twenty-one years (1990-2010). Were used method of least squares normal to see the impact of some economic indicators and agricultural independent variable approved financing agricultural output, and most important conclusions reached by the research is that the volume of agricultural imports exceeds the volume of agricultural exports, that features agricultural trade is negative during the period of the research. This reflects the level low capacity of the agricultural sector For both countries. And show the results of the analysis also moral cultivation "(X1) for each of Iraq and Saudi Arabia, but for a variable agricultural exports (X2) has emerged not significant in its impact growth rate of agricultural output in both Iraq and Saudi Arabia, while the variable rate exposure economic agricultural (X3) has appeared in the moral influence on the growth of agricultural output in both countries, As for changing the relative importance of the surplus or deficit of the balance of payments to Total local output (X4) it has appeared in the moral influence on the growth of agricultural output in Iraq only and non Manuetha in Saudi Arabia It has been found through analysis the lack of moral variable average real per capita income (X5) in both Iraq and Saudi Arabia, has also been reached to a set of findings and recommendations.
Abstract: A comparative study was done to evaluate quantitative efficiency of two methods for seed extraction: air blowering and water soaking of two onion varieties (Local White and Imported Texax Early Grano), and two methods for seeds extraction from a residual product resulted from the two previous methods i.e. water soaking to the residual product produced by air blowering and air blowering to the residual product produced by water soaking. Also the aims of this study is to evaluate seed viability and seed vigour of the extracted seeds. The results indicated that air blowering method was significantly superior in seeds weight and percentage of the extracted seeds, whereas, water soaking method gave the best results in seed purity percentage, seed index, true value of the extracted seeds and also seed viability and seedling vigour characters i.e. seedling and root length, fresh and dry weight of the seedling. The results also showed that the seeds resulted by water soaking from the residual product by air blowering were ineffective as it gave a low weight of extracted seeds(2.53 %) and low viability and seedling vigour, whereas, the seeds resulted by air blowering from the residual product by water soaking gave a hight weight of extracted seeds (36.29 %)and a good quantity and quality of seed viability and vigour. The imported variety (Texax Early Grano) was superior than the local white variety in all traits of above mention studied.
Abstract: This study was conducted in the vegetable farm/Hort. & land scape Dept./College of Agric. & Forestry / Mosul Univ. to study the effect of two levels of phosphate fertilization, zero, 40 kg P2O5/Donum, and spraying with three levels of seaweed extract, kelp 40, Zero, 2,4 ml/l in two pea cultivars namely: "Little Marvel and Fabreca". Plants were sprayed twice, the first one at 3-5 true leaf stage, whereas the second after 15 days from the first spraying. Results indicated that phosphate fertilization & seaweed extract showed a clearly effects in TSS, protein percentage of seeds, nitrogen & phosphorus concentrations of leaves, in addition to number of root nodules/plant. Phosphate treatment gave the highest protein percentage (30.08%), while spraying with 4 ml/l of seaweed extract resulted in the highest values of nitrogen, phosphorus concentrations in leaves, and the large number of root nodules/plant. The results revealed also that cultivars varied between them in all parameters studied.
Abstract: A laboratory study was conducted to determine the effect of irrigation water quality on capacity and rate of potassium release in some calcareous soils in Nineveh province. It was constructed by miscible displacement technique with natural un disturbed soil columns using chlorine and sulfuric water of two different textured soils from location of Zummar of clayey and Sheikh Mohammed of loamy silt texture for ten irrigation epochs on the basis of porosity volume (PV). Results indicated for presence values of desorbed potassium rate with increase of porosity volumes passed through soil columns. Sulfuric water caused more desorption of potassium in comparison with chlorine water. Desorption capacity rate were 1.93, 2.92 c.mole.kg-1 for Sheikh Mohammed and Zummar locations respectively by using sulfuric water, while desorbed potassium by using chlorine water for the same Soils were 1.12, 2.01 c.mole.kg-1. Mathematical description for desorption process appeared harmony of diffusion equation, power function equation, first order equation, zero order equation, while Elovitch equation did not describe desorption process with the same efficiency. K+ desorption rate due to diffusion equation by using chlorine water were 0.06, 1.2 c.mole.kg-1.min-½ for the Soil of Sheikh Mohammed and Zummar locations respectively, yet using sulfuric water increased desorption rate which were 0.14, 0.22 c.mole.kg-1.min-½ for the same locations respectively.
Abstract: In this study the runoff collected from catchment area , is utilized directly to irrigated wheat crop to meet its the water requirements with design the micro catchment water harvesting system (ratio catchment C area to crop area CA) based on the climate , crop and soil data. The design rainfall was estimated at 80% probability and crop water requirement by Penman-Monteith. The experiment was divided to three ratioC:CA 3:1 , 8:1 and 10:1 on the area of 25m2 , dikes are used on the cropped area with 15 cm height to collect the maximal runoff from the catchment area and use water content in soil profile for increasing yield. The results showed that the grain yield increases from 1260 kg/ha to 1700 kg/ha with the increase in the size of catchment area , and that the water content in crop area and the collected runoff and its percentage of materiel suspended increase with the increase in depth of rain dropping on catchment area.
Abstract: The Present Study shows that the agricultural Land taxes represent 1/10 percentage. But now these taxes developed as a result of floor of the state and passing from guard state to interference state to end by recent producer state. The taxes became as active tool for the policy of financial and realization of goals for economic and social development. Many laws published to organize the rules of agricultural land taxes which its receptacle deal with agricultural land, cultured or un- cultured, virtuous or not virtuous for tillage and with a certain percentage of produce depending on the elements of rent value. And the taxes were imposed with an average from "1% to 15%", depending on the experience of experts in this field. Our study confirms that, by using soil survey and classification and its attached map, and using equations deals with properties of soil, we get a rational estimation of tax or imposition on agricultural land in an equity and justice grade.
Abstract: This study was designed to detect an improvement ability of Fenugreek seeds and Methionine on some biochemical parameters and antioxidants status in quail females.The trial included six treatments: first (fenugreek seeds), second (fenugreek + H2O2), third (methionine), fourth (methionine + H2O2), fifth Oxidative stress (H2O2), sixth (control). The results showed that H2O2 treatment caused a significant increase (P ≤ 0.05) in glucose,T.G, T. cholesterol, LDL-C, VLDL-C and atherogenic risk index in blood serum, while HDL-C decreased significantly, as well as MDA level was increased significantly in tissues such as (heart, liver, kidney, pancreas and ovary) whereas GSH level was decreased compared with control group, Corticosterone hormone as well as elevated. Fenugreek seeds alone or with H2O2 treatment caused a significant decrease in glucose & T.G levels as well as in AST & ALT enzymes,while GSH level of heart tissue was increased. Methionine treatment caused a significant increase in GSH level of heart tissue while Corticosterone hormone decreased significantly indicating the antioxidant ability of antioxidants materials to exerted and improvement of some biochemical parameters and antioxidants status in quail females.

Abstract: The results of the chemical analysis showed that the values of each of the leaves content of the Pinus halepensis Mill. seedlings of the total proteins , chlorophyll have increased significantly with increasing the power of electrocution at 4 and 6 amp. Also each of leaves content of the total phenols and potassium increased at 6 amp power of electrocution. So, one can note that all periods of electrocution caused a significant outweigh in all the investigated chemical characteristics in comparison to control treatment except for attribute of the leaves content of potassium. The obtained results indicate treating seeds with Gibberellic acid led to a significant increase in all the chemical characteristics of seedlings compared to the comparative treatment except seedling leaf content of the total chlorophyll.
Abstract: Four trees growing in Ninavah plantation were chosen, two of them are Pinus brutiaTen.and the others are Cupressus sempervirens var. pyramidalis Tozz.. The trees were filled, from each tree six sample discs of (25 mm) thick were taken, three of them directly above (1.3m) and the others below, then each disc were radially sawn in the four directions of the radius, the test specimens were cut from these with the dimensions of (25 × 25 × 25 mm) used for measuring annual ring width and wood specific gravity. A significant difference in ring width and wood specific gravity was observed along the radial axis from pith to bark, the value of ring width decreases while wood specific gravity increase, and significant negative relationships had been found between ring width and wood specific gravity in both pine and cypress. There were significant difference between the trees. The mean value of ring width was (3.951mm) for pine while it was (3.141mm) for cypress, and the mean wood specific gravity of pine was (0.556) while it was (0.505) for cypress.
Abstract: Centroid method with three of the traditional methods used to estimate the volume of logs (Newton`s, Smalien`s, Huber`s) and four species Eucalyptus, Platanus, Cypress and Pine. Different in terms of natural growth had been adopted to determine which of these equations are the best and most accurate in estimating the volume of these species so (30) tree of each species were taken. The measurements taken are the diameter at the breast, height and elevations at various levels began to 0.3, 1.3, 2.3 and up to 6.3 m which represents length of the piece of wood desired in market, and through the use of ordinary models for Newton`s, Smalien`s, Huber`s, Centroid and the real comparing of the volume of the equations and the true volume by using bias, standard error and T-test, we found that equations of comparisons have no-significant effect, but the equation of Newton`s have best estimate for rest of equations in roughly, we recommend using the equation of Newton`s was the best in estimate of volume of the logs of wood.
Abstract: Afield experiment was carried out during the winter seasons of 2008-2009 and 2009-2010 in Salamya which is located at 34 Km southern from Mosul city.

Abstract: A field experiment conducted In the agronomic season (2012) to study the influence of landside through two levels traditional landside with moldboard plow and the plow with manufactured landside with two levels of moisture content (9.22 – 18.36)%. according to RCBD which has been used with split plot method and its influence in measuring performance (draw bar force. slippage percentage. adhesion force. vertical and horizontal deviation percentage. the coefficient of working width exploitation and performance efficiency). Results of using plow with manufactured landside led to decrease the draw bar force. slippage percentage. adhesion force soil and horizontal deviation percentage, it also led to increase the coefficient of working width exploitation and performance efficiency. While the increase of moisture content led to decrease the draw bar force, slippage percentage, and to increase the performance efficiency. The interference between the moisture content 18.36% with manufactured landside recorded a decrease in the draw bar force and high value for performance efficiency while the interference between the moisture content 18.36% for the plow with traditional landsiderecorded less slippage percentage and recording less adhesion force with moisture content 9.22% for the plow with manufactured landside
Abstract: This study aimed to detect the effect of adding two plant extracts namely; Spearmint (Mintha spicata L.) and Thyme (Thymus vulgaris) at different concentrations on some microbiological and sensory properties of white soft cheese manufactured in the laboratory. Cow milk was used in processing the cheese. Control cheese manufactured by using the rennet only, while the other cheese treatments were made by adding separately different concentrations (10, 20, and 30 ml/100 grams of curd) of mint and thyme extracts to the curd. The produced cheese samples were studied microbiologically and organoleptic ally during storage at intervals (fresh, 3, 6, 9, and 12 days) at 4 C° in the refrigerator. The results of the microbiological tests revealed, the superiority of cheese samples produced by adding the plant extracts in extending the shelf-life of the cheese compared to control samples. Using higher concentrations (20 and 30) of either mint or thyme extract was found to be the most effective in decreasing the total bacterial count, and in earlier disappearance of coliform and staphylococcus compared to the control cheese. The yeast and mold appeared late during the storage in the treated cheese, while they appeared earlier in the control. The results of the organoleptic properties during cold storage revealed, that, all samples of cheese manufactured in this study got scores which made them acceptable by the consumers. It is also found that, there was no negative affect as a result of adding the two types of extracts on the sensory properties of the manufactured white soft cheese.
Abstract: The study showed the effect of using Flaxseed oil as a source for Omega-3 in ice-cream and as a partial substitute for milk fat in preparing the mixture. Two treatments were made with replacement rates of (1.5, 2.5, 5, and 7.5%). Flaxseed oil, fortified with Vitamin E as an antioxidant, was added to one of them, while the Vitamin E was not added to the other. The results showed there was increase in melting property increase rates of replacement, while the overrun and viscosity increase rates of replacement, compared with a sample comparison, but there was a decrease in cholesterol while increased peroxide value and acidity during extended storage amounting to one day and (7 and 14) days, Omega-3- fortified treatments showed degrees of noticeable evaluation lower than the comparison sample, but there was a preference for the sample fortified with Vitamin E.
Abstract: The results indicated that the kinds of legume seeds and storage period affect to the activity of khapra beetle which represented in the population density of the insects and loss weight of infested seeds and growth rate of insect.

Abstract: The effects of a dipolar static magnetic field of strength 400, 800, 1200 and 1600 Gauss were prepared locally, on the ultra-structure of E. coli type 1 bacterium cells have been studied. Equal volumes of liquid culture media were exposed to the magnetic field for different periods, the three most effective periods, namely: 24 hrs, 48 hrs and 72 hrs were chosen for all our experimental studies. After API kit test of treated E. coli culture media as control group. Results indicated that exposure of the microorganisms to the demonstrated magnetic field caused pronounced changes in the Arginine dihydrolase (ADH), Citrate utilization (CIT) and Gelatinase (GEL) were observed on the cell growth. Besides, changes in the morphology of the E. coli colonies were observed after exposure period and subculture on MacConkey agar. Furthermore, the bacterial growth subculture tested for morphological and biological activity, the results suggested that a mutation occurred in bacterial cells.
Abstract: For the first time wilt symptoms have been detected on the Snapdragon (Antirrhinum majus L) plants cultivated in the parks of Mosul University. The isolation of fungi from wilted plants on PDA medium revealed the presence of seven genera including; Alternaria, Aspergillus, Cladosporium, Fusarium, Macrophomina, Penicillium and Stemphyllium. Fusarium oxysporum was the most frequent fungi approached 36.0 x 102 Colony Forming Unit/gm soil. F.oxysporum reduced significantly the chlorophyll content of infected plants, and the percentage of its inhibition increased up to 81.88 in severe infections. The infection caused significance stunting of plants when plant height inhibited by 58.09% in dead plants. Antagonism ability of Trichoderma species as T.harzianum, T. viride, and T. reesei against F. oxysporum showed control efficiency of.1.666, 2.333, and 2.666 respectively.
Abstract: The present study reports the chemical composition and atmospheric salt load rainwater of Mosul city/ Nineveh Governorate / Iraq. The sampling were done from October 2012 to March 2013. Twenty six samples were collected and analyzed for pH, ion concentration (Ca++, Mg++, K+, Na+, CI-, HCO3-, SO4--) and electrical conductivity. Total rainwater was 338.55mm. The results show that the volume weighted mean (VWM) pH and electrical conductivity in the rainwater were 6.83 and 114.22µS.cm-1 respectively. Cation and anion concentration took the following order : Ca++ ˃ Mg++ ˃ Na+ ˃ K+ and HCO3- ˃ CI- ˃ SO4=. HCO3- and Ca++ contributed 65.3% of the total ions in the rainwater. Equivalents ratios for different ionic components to sodium, revealed higher values in rainwater than that of seawater. This indicates the dominance of non-marine in studied samples. Analyses revealed that loads delivered from the fallen precipitation in the urban city of Mosul was about 0.1167kg cl-/m3 of chloride in rainwater which equal numerically to 395kg NaCI. h-1 of land.
