Abstract: The agricultural imports are considered as one of the basis of the agricultural foreign commerce which most countries depend on for solving the shortage of agricultural products that are unable to provide for their people in a short term. The strategic corns have a great rank in the economies of developing countries because of their alimental importance and their contribution in the foreign commerce. Despite their importance, these crops are unavailable in these countries for several reasons: the first reason is disusing a correct agricultural policy, especially in the scope of organizing their productive resources to make a high economic efficiency in producing agricultural corps in order to increase the production of these corps, the second reason is the carelessness of lands reclamation and the third one is the lack of quantitative and qualitative incentives presented to the producers of the strategic crops. According to mentioned above, this study depends on a supposition that there are some variables are affect the imports of the strategic corns in some underdeveloped countries, hence, the following developing countries are chosen (Iraq, Egypt, Syria, Tunisia, Turkey, Thailand, Indonesia, Morocco, Jordan, Pakistan), and four strategic corps are chosen: (Wheat, Barley, Rice, Maize). The time series data were used to estimate the phenomenon under study for every country separately, because it reflects the occurring changes in the imported quantities of the strategic corps, and they have features and characteristics differ from country to another according to the political and economic structure of these countries. To achieve best results, a standard model was applied with four formulas: (linear formula, double logarithm, semi-logarithm, reflected logarithm). The most important conclusions of this research were the alimental gap in the underdeveloped countries which results in depending grossly on importing the strategic corns under study in order to filling the increased alimental gap and increased local demand of these corps, and this has undesired economic effect like alimental dependence on the foreign countries.

Abstract: The study aimed assessment and analysis of the demand function for poultry meat in Iraq for a period (1990-2009) once without changing time and again with the time factor as well as find food gap and the values ​​of elasticities (price and Aldkhalah and Cross) and predict the required quantities of this meat in the coming years. It was found that the variables (the average per capita income and the size of the population and the prices of poultry meat, red meat, and time) has been deleted variable V average prices of fish meat from the equation for not Manueth. Has appeared significant in influencing and varying in the degree of impact, it turns out that the coefficient of determination of the model with time has reached (97.9%), while the coefficient of determination with no time (97%) This indicates that analysis with time has increased from clarification impact on payment of poultry meat, and the results show the growing size of the food gap and rate 28.18 thousand tons of poultry meat in the period studied, also reached values ​​elasticities without and with time and sequentially price (-0.167, -0.123) and Aldkhalah (0.017, 0.032) and cross of red meat (0.192, .240) and cross the fish meat with time (-0.221) value price elasticity of demand 0.510, indicating that demand for poultry meat is flexible towards change in price, while the flexibility of domestic demand 0.017, indicating that the required quantity of the commodity changed much less than the change in income.

Abstract: The study was conducted on nine clay samples collected from three different soils of northern Iraq (Mukhmour, Shikhan and Zakho) which varied in climatic conditions (precipitations and temperatures).Permanent surface charge on clay surfaces was measured through adsorption of lithium chloride experience before and after removing iron oxides. Results showed that the highest values of permanent negative charge on clay surfaces before removing iron oxides was found in Mukhmour soil with average 34.5 C.mol. kg-1. clay, while the lowest values appeared in clay fraction of Zakho soil (18.1 C.mol. kg-1. clay), but in Shikhan soil,the negative charge values was at average of (20.0 C.mol. kg-1 clay). The highest stability of negative surface charge was found at pH between values (3-5). The distribution of negative charges within soil profiles showed an increase in values with depth and in all studied soils. Results also reveals very low positive surface charge compared with negative surface charge. However, the results of the lithium chloride adsorption experiment have indicated that the removal of iron oxides from clay fraction had a clear effect on increasing in the values of negative surface charge in all study soils.The rates of increase associated mainly with the iron oxides content of the clay fractions but the impact of removing iron oxides on the values of positive surface charge were minor and had no clear behavior. From the above study it can be concluded that the variations in the values of surface of clay surface charge clearly reflects the levels of weathering and the degrees of soil development.

Abstract: Nine soil samples were selected from three different locations in Ninavah and Duhok Governorates. The locations included Makhmour, Hamdania and Zakho. The studied areas were selected according the variation of annual temperature and rainfall. Soil orders of Makhmour and Hamdania are both within Aridisols, but Zakho soil is a Vertisols. Soil profiles were described according to USDA and three soil samples from each profile were collected from three depths (0-20, 20-40 and 40-60 cm). Chemical analysis was conducted using (XRF) Technique. Calculation of weathering parameters has been done such as chemical index of variations (CIA), index of chemical variation (ICV) and weathering index (WI). Results of weathering parameters included that the highest levels of weathering levels was found in Zakho soil (Average annual rainfall 550 mm) and the lowest weathering levels in Makhmour soil (Average annual rainfall 240 mm). Results of XRF Analysis also showed a clear increasing in immobile oxides of (SiO2, Fe2O3 and Al2O3) and trace (rare) elements (ZrO, MnO and TiO2) in Zakho soil and decreased in Makhmour soil. However the mobile oxides of (CaO) and the loss in ignition was increased in Makhmour soil and gradually decreased in Hamdania and reach its lowest levels in Zakho soil.

Abstract: This study was carried out in three selected areas from North Iraq included (Makhmour, Shikhan and Zakho).these location Varied in annual temperature and rainfall .Nine soil samples were collected from three soil profiles (one soil profile from each location). Clay was separated without using any corrosive acid or base, except sodium acetate in order to remove calcium carbonate. Variable charge (pH-dependent charge) was measured using potentiometric titration. Results from titration curves showed a clear variations in positions of (ZPC) and the amounts of negative and positive charges from different samples. The extent of (ZPC) varies from (pH 4.4-5.8).However the amount of negative varies between(100-180) Cmole/kg. and the positive charge between(150-350) C.mole/kg. These variations in potentiometric titration curves are partially related to the presence of varying amounts of iron oxides and also the variations in type of minerals dominant in clay samples .In addition to that, there is a possibility of the presence of some calcium carbonate in clay that not completely removed by treatments with sodium-acetate.

Abstract: This study aimed to biological and chemical control for the most important root rot disease on barley in Iraq. Seven barley culivars were tested to barley root rot pathogens showed that all the cultivars have root rot infections and Iba cuv. has been the lowest level (0.45) in the greenhouse. At the field, All the cuvs. also have shown the infection of root rot and Al- Jazerah cuv. has the lowest class under natural conditions. Also, this cuv. characterized by an increase in the flag leaf (10.93cm2) and produced a greater number of spikes (2.13 spike / plant) and the highest rate of dry weight (4.53 gm/plant). The local Aswad cuv. characterized with the high content of salsilic acid (1.03%). Using the Veiscular Arbsuculur Mycorrhiza (VAM) fungus (Glomus intradices) has shown a decrease in the infection of two barley classes (Jazerah and Zanbaca) by root rot and in improving some characteristics of barley classes under the conditions of industrial infection which reflects on improving some plant characteristics in the greenhouse. At the field, Glomus intradices were efficient in decreasing the disease sevenity of barley root rot (0.34) which was morally equivalent to the best Fungicide (Vitavax) (0.65),This reflects on some plant characteristics and on the barley productivity. Thus, the productivity has increased from 697.3 to 1313.5 ton/hectare.fungicide. Under the industrial conditions of infection in the greenhouse, the fungicide (Vitavax and Raxil) had been the best for controlling disease and improving some characteristics of barley, followed by Mancozeb and Dividend. At the field, the pesticide (Vitavax) had shown superiority in decreasing the disease severity from 0.65 to 0.29 and improving some yield characteristics and raising the productivity from 697.3 to 1268 ton/hectare as well as the pesticide  Mancozeb which raises productivity from 697.3 to 1340.5 ton/hectare.

Abstract: To determine the optimum sowing date and plant population for safflower crop (Carthamus tinctorius L.), a factorial experiment was conducted by using randomized completed block design with three replications in AL-Rashidia location about (20 km) west north Nineveh province, Iraq, during the 2008-2009 and 2009-2010 winter growing seasons. Three sowing dates (1st, 3rd October, 4th, 5th November and 2nd,1st December for two seasons 2008-2009 and 2009-2010 respectively) and two plant populations (50000 and 100000 plants.ha-1) were selected. Hartinan, Syrian and Gila cultivars were used. The results showed that the different sowing dates had significant effect on growth characters, yield, yield components and quality, except linoleic acid in 2009-2010 season, the highest mean values were obtained at second sowing date in the two seasons 2008-2009 and 2009-2010. Safflower cultivars significantly differed for all the studied yield, its component and seed quality traits in both seasons, the highest mean values were obtained from Syrian cultivar in both seasons. Seed yield and oil yield influenced by different plant population significantly. Plant population of 50000 plants.ha-1 gave the highest mean for seed oil content and oil yield, while increasing the plant population to 100000 plants.ha-1 caused a significant increase of plant height and palmitic acid percentage in both growing seasons. The result of interaction among sowing dates, cultivars and plant population showed that the highest seed yield was obtained in Syrian cultivar sown in November using plant population of 50000 plants.ha-1. Therefore, Syrian cultivar sown in November with plant population of 50000 plants.ha-1 is recommended for this region.

Abstract: The hypothesis of the present study was that the Ultra-high temperature (UHT) processing of fluid milk-fortified with Zn, Fe or Mg individually might change the perception of milk flavor as compared to normal UHT milk without fortification. Samples of fortified milk with zinc, iron and magnesium have been processed by a bench-top UHT plant (145 ºC/6 s) and filled into transparent polyethylene terephthalate containers. The milk samples were stored in closed incubator at 30 ºC for 60 days without exposing to light. At 10 and 30 days intervals, the samples were assessed for TBA test and sensory evaluation respectively. The main concern of this work was to evaluate the effect of UHT processing on the level of oxidation by both chemical and sensory evaluation of the fortified milks. Results showed that the values of TBA test increased significantly (p≤0.05) at the end of the storage life (60 d/30 ºC). Sensory evaluation of fortified milks with Zn, Fe and Mg showed miscellaneous results.

Abstract: Field experiment was preformed to determine the effect of  soil moisture state on the runoff volume and soil loss by using standard flumes with dimension of 100*12*30 cm. The flumes were filled with soil materials The results of this study pointed out that the moist state primarily appeared increasing the runoff volume and soil loss in comparison with dry state. The rate of soil loss under water erosion was found to be proportionally related with the soil moisture content. Also the results of the statistical analysis by regressing rainfall depth against runoff depth showed that threshold value of the surface runoff resulted from moist soil state were less than that of dry state.
