Abstract: Poverty is considered a complicated phenomenon which has serious social, political and economic dimensions. Poverty scope is unlimited by a certain geographic region or a certain period of time. If the problem of poverty had increased and with no solution for it, then, there would have been negative reflections that might have threatened the whole community. Thus, this research aims at explaining the role of rural development in fighting poverty in Iraq for the period 1980-2005 by recognizing the economic variables of development. The relation represented poverty index (Individual Share of Income) being a relevant variable and its Limited factors. These factors are (Agricultural Investment, Invested capital in agriculture, cultivated area, Agricultural Productivity, Inhabitants of the Countryside, and expenditure on Education) as being independent variables. It has been clear throughout the analysis that there is an effect for Capital invested in agriculture, agricultural productivity, income demand flexibility has been estimated to recognize the economic welfare of agricultural sector in Iraq. The ratio is 1.7%.This signifies that individual income in this sector does not achieve the wishes in Consumption. Therefore, agricultural sector in Iraq Suffers from shortage of providing so many necessary needs for production, investment and agricultural techniques. The backwardness of agricultural development in Iraq represents the most significant features of productivity imbalances in which the Iraqi economy faces. This has been reflected upon poverty in agricultural sector. People living in rural areas under poverty line from 70 -80 % and it is a high percentage . Therefore, it is necessary to use policies and rural development programs which may work to increase local capacities and to concentrate upon the poor and to encourage sustainable development and to find out new chances for work.
Abstract: The research aims at estimating and analyzing the function of imports of some main agricultural products in some developing countries from 1980- 2005. Four developing countries were chosen : Egypt, Jordan, Morocco, and Syria. These countries are characterized by increase of the quantities of their imports of four types of agricultural crops: Sesame, wheat, rice, and sugar. An econometrical model was used in three formulas which are : linear double- logramatic, and semi – logramatic to estimate the functions of the imports for the mentioned products during the research period. To prove the hypothesis, we have depended on the economical theory concepts and the previous studies which discussed the same subject and collected the variables of study from time serials data and to each country individually because they represent its properties and features which vary from one country to another, and the following conclusions were found : The significant variable (local product) of rice and (the foreign exchange rate) in affecting rice imports in Morocco; the significant variables (purchase price) in importing sesame in Egypt and rice in Morocco; the significant variables (National income) in importing sesame in Egypt and rice in Morocco and sugar in Syria; the significant variable (population rate) in importing wheat in Jordan, rice in Morocco and Sugar in Syria.
Abstract: The study aimed at estimating the optimum use levels of seeds, fertilizer, machinery and manual work resources involved in producing Coker 310 and Asur classes of cotton depending on field data, season 2001-2002 and for the sample, consisting of 72 farmers in Nimrod district/Ninevah governorate. The risk impact on the optimum levels were studied, because the economic studies that ignore risk in solving the rain-dependent cultivation problems recommend levels, which exceed the levels of the use imposed by risk. When we compare the optimum levels of production resources under the risk conditions, we observe that they are smaller under certainty conditions. For the class Coker 310, levels were 1.41% for seeds, 13.82% for fertilizers, 3% for machinery and 9.59% for the manual work. The same were for the class Asur as risk leads to the decrease of use levels with the rates; 1.59% for seeds, 13.59% for fertilizers, 2.63% for machinery and 7.31% for the manual work. Results indicated that the class Asur led to decrease the optimum use of seeds and manual work resources, and increased the optimum use of fertilizers and machinery resources compared to the class Coker 310. It is clear that risk-reluctant farmers will respond to the risk conditions they encounter by decreasing the use levels of the resources to the minimum. This requires decreasing cotton production resources to decrease the economic loss accompanies that.

Abstract: Data were collected from 83 Awassi ewes raised on to two flocks during the lambing season (2003-2004). The first flock belongs to private farmers, at Al-Nahrawan region, 5 Kms to the west of Mosul city, whereas the second flock belongs to the General Directorate of Applied Agriculture Researches (Animal Husbandry Station of Mosul). 750 and 614 records of test – day of milk yield and fat percentage, respectively, were used in this study. Data were subjected to statistical analysis using by General Linear Model (GLM) to study the effect of fixed factors on milk yield and fat percentage, to find the correlation coefficients between variables studied and prediction equations of total milk yield . The overall mean of TDMY (Test Day Milk Yield) and fat percentage were 569.824 g, %4.461 respectively. The effects of flock, age of ewe, stage of lactation were significant (p < 0.01) on TDMY. However, the effect of sex of lamb was not significant . All the non-genetic factors studied had significant effect (p < 0.01) on fat percentage. Repeatability estimates for TDMY and fat percentage were 0.481, 0.273 respectively.
Abstract: Synthetic model systems of local sour orange juice were prepared by different concentrations 10, 30 and 50%, with different contents of some compounds (ascorbic acid, reducing sugar, amino acids) that might play a role in brown pigments formation. Samples were stored at 20, 30 and 40ْC for 4 months. Results showed that increasing temperature and period storage caused decreasing in ascorbic acid content and increasing melanoidins formation of model system. Increasing total soluble solids concentration caused decreasing in ascorbic acid degradation and melanoidins formation. The study showed that high value of melanoidins formation was noticed in model system that contained ascorbic acid. This indicated that ascorbic acid was the principle component that responsible for nonenzymatic browning development in this type of food products.

Abstract: The effect of rocket ( Eruca sativa ) leave juice on induction of sperm - head abnormalities was studied using the white mice males , the effect of cyclophsphamide (Cp) on such abnormalities was studied as well . In addition to studying the effect of different combinations between the plant juice and the mutagen (Cp) . The results indicated that rocket juice 0.1 , 0.25 , 0.5ml / animal administrated orally had no effect on induction of sperm - head abnormalities , while Cp induced abnormalities in order of 5 times the background level , which remain unrepaired even after 6 days . The combinations such as using the juice before the mutagen (J/Cp) or using the juice with the mutagen (J+Cp) were able to lower the abnormalities almost to the baseline level (i.e., the negative control) or slightly higher but , without statistical significancy (P
Abstract: The effect of the rocket juice Eruca sativa (A cruciferous plant ) and its counter effect on chromosomal aberrations induced by Cyclophosphamide (Cp) drug was studied in white mice bone marrow cells .The effect of different combinations of plant juice and mutagen was studied to find out the patterns of protection exert on the aberrations . Results revealed that rocket juice 0.1 , 0.25 , 0.5 / ml animal administrated orally had no effect on induction of chromosomal aberrations , while Cp administrated orally (50 mg / Kg of body weight) , increased the chromosomal aberrations 7 – 11 times of the natural level (Negative control) . Natural repair and activities failed to restore the natural levels as the aberrations still very high .The structural chromosomal aberrations (Chromosome breaks , chromatid breaks , ring chromosomes , and dicentric chromosomes ) induced by Cp were lowered upon using the juice before or after or with the mutagen with significant difference . The prevention (Protection) was proportional to time intervals of treatments , and reached its maximum value (91 % ) when treatment with juice before treatment with mutagen was conducted for 6 days .
Abstract: The research has conducted to investigate some wood properties of Leucaena leucocephala growing in the middle of Iraq. Specimens were taken from five trees around Baghdad to study the variation of fiber dimension and specific gravity longitudinally and transversely among the stem. Results showed that length , diameter , and wall thicknesses of fibers near the bark were more than that located near the pith of the tree. Effect of longitudinal factor was not steady ; while fiber length was slightly more in the base than in the upper stem levels, fiber diameter and wall thickness had their higher mean values at the higher positions of stem. Wood specific gravity showed no significant differences neither longitudinally nor transversally among the stem. Results referred to the possibility of using this wood species for pulp production in addition to its conventional uses.
Abstract: The study was carried out in Dohok in the north of Iraq, exactly in Zakho region, Where Populus nigra stands are widely spread within irrigated stands that are depending on feshkhabour river. Study area involved (45) samples which are randomly selected regions that represents state of the stands. Each sample was (0.1) hectare area, from these plots eighty six reading were recorded for the diameter over and under the bark taken from different height level for 13 standard trees that represent all ages, densities, and diameters for these stands. Data were inserted in linear and non linear regression program, to determine bark factor (K), which found to be (0.95). The volume of the bark was calculated by taking (30) standard trees that represent all ages and densities. Tree volume over and under the bark and difference between them were calculated. Several mathematical equations were found that represent the relation between bark volume as a depended variable, and the diameter at d.b.h. and total height as an in depended variables. From these equations, bark volume was estimated depending on these easy in depended variables. Also we be able to found a mathematical equation to estimate bark thickness from diameter.
Abstract: Yield models for Pinus brutia Ten stands grown of Sinjar regionhas been prepared depending on data collected from 30 sample plots, the area of each plot was (0.25) ha. Different variables of each plot (volume / ha , dominant height , mean diameter and age)was measured and stepwise, multiple, and non-linear regressions were used to develop different equations . The dependent variables were yield per hectare while the independent variable were Age, H0, and Da in their original and transformed and combined forms. After screening of the developed equations the following one were selected,: V=-2.774+43050.7(1-e(-0.0002A)) R2=92.4 S.E%=306.13 as it give the best fit compared to the remaining equations. Since this study can be considered as on initial step in predicting the yield tables for pinus brutia Ten. Plantations, also, we were determining the mean annual increment and current annual increment , to find out the rotation of maximum volume production.
Abstract: Genetic analysis of means and phenotypic variances for grain yield and several traits in five generation (P1,P2,F2,F3, and F4) for to crosses of a six row barley , Hordeum vulgare L.(Gezera-1 x Benedict and Baraka x Arivate) were carried out to estimate: gene action parameters, component of genetic variance, environmental variance ,average degree of dominance ,narrow sense heritability and expected genetic advance from selection in each of segregating generations (F2,F3 and F4). Tow models were applied in analyzing the component of generation means and weighted least squares method where used to analyze the phenotypic variance of generations rank. The results showed that :(1) the three parameter genetic models were adequate for the inheritance of 100 grain weight in the tow crosses and there were additive, dominance and epistemic effects on the other characters .(2) over dominance for plant height, number of spikes, grain yield and 100 grain weight but partial dominance for other traits in the two crosses .(3) narrow sense heritability and expected genetic advance from selection were higher in the F4 for studied traits.
Abstract: This study loan conducted in the fields of Agriculture and forestry collage in the beginning of 2008 to investigate the effect of pressure 3 and 2 bar, spray nozzle heights 180 and 90 cm and the irrigated area between sprayer 144, 216 and 324m2 and the interaction effect of the three previous factors on the coefficient of water distribution uniformity (UC) and distribution uniformity (DU). The randomized block design and Duncan's multiple range were tested for the comparison between the used means. Results showed that there were significant differences among the three factors, the pressure 3 bar gave the highest coefficient of water distribution uniformity and distribution uniformity, The height 180cm gave the highest coefficient and highest distribution uniformity and the under area gave the highest coefficient and distribution uniformity. The interaction among the three (sparer 3 bar, height 180 cm and the smolar area) gave the highest coefficient of water distribution which was 87.266% and highest distribution uniformity which was 76.866%.
