Abstract: This research aims studying the affecting of agricultural loans in the growth of agricultural output for the selected Arab countries: Jordan, Tunisia, Saudi Arabia, Syria, Egypt, and Morocco. For the purpose of measuring this impact, in order to prove the hypothesis of the research that included distinctness agricultural loans in the growth rates of agricultural output in the selected sample of Arab States has been using method two-stage least squares that required, the use of time-series data for agricultural loans during the period 1980-2003 as dependent variable and interest rate on the total agricultural loans and capital accumulation s independent variable in the first phase and the second phase included the annual growth rate of agricultural output for the same period as dependent variable that estimated total agricultural loans in the first phase. One of the most important conclusions, it was found that the increase in aggregate impact on agricultural loans to increase the annual growth rate of agricultural output in the Arab countries selected but this increase varied between these countries.
Abstract: The study included extraction of tannic acid from grape seeds and pomegranate peels , their content of tannic acid were 4.1 and 27.6 g/100g ( dry weight), respectively .The quality tests which done on extracted tannic acid from both sources showed positive results, where the increasing tannic acid concentration leads to increase killing effect on studied microorganisms especially at highest concentration (2%) .These results showed that extracted tannic acid from both sources can be used as preservation material in food processing and component of cosmetic materials and pharmacological drugs.
Abstract: The price proving issues considers one of the most issues that is most of the world countries suffering from it because of the direct connected with the people life and with their lived levels this is from one side, and national economics systematizing (supply and demand) from another side. As we know, The wheat crop is an importance food strategy crop that is we must interest in it with specifically for food secure requirements and inquest the self-security that is all needed concerning with studies the supporting policies and affected it on producing and consumption in the wheat crop. In this research we shall focus on wheat price support by considering an important food commodities for the Iraqi people, therefore the state aimed from the support policies for this crop specifically to stability prices it in the market and saving it for the people that their having limited income and it saving the motive for the producer to continued the producing and development the producing. It is show that trend timer general chronological taken ascend facing to all of the producing and consumption with increasing rate assumed (-2.70) and 0.65 on the successively through mentioned period. confirm the analysis found the policies that Iraq country to follow it trend wheat crop have positive effect on the producer welfare (his income and his profit level) since the study time.
Abstract: Field experiment was conducted during the season 2005-2006 in Singar - Mosul city to investigate the effects of high level (280 N, 260 P2O5) kg ha-1 and very high level (320 N, 300 P2O5) kg ha-1 fertilizer, pinch and without pinch, and plant seed rate sowing (0.6, 0.8, 1.0, 1.2) g/10m2 cultivated within 3, 4, 5, 6 rows respectively in (10) m2 plot area on growth and yield of Nigella sativa L. The experiment was laid out in randomized complete block design with three replications. The results indicated that. Very high level of nitrogen and phosphorus caused a significant increase in plant length, stem diameter, fresh weight, plant seed yield and total seeds yield kg/ha, were as branches number, and fruits number cannot be effected significantly by previous factor. Pinching causes a significantly increased in branches number, fruits number, while plant high decreased significantly. Increased seed rate sowing from 0.6 to 1.2 g/10m2 caused a significant increasing in branches number, fresh weight, and plant seeds yield, while stem diameter, and fruits number didn’t effected significantly by this factor except total seeds yield kg/ha which increased significantly when seed rate sowing are increased to 1.2g/10m2 and they reach 651.85, 843.56, 1076.51, 1232.67 kg/ha for the four seed rate consecutively.
Abstract: The importance of the research comes to show the effect of variation in income distribution upon the rates of agricultural product in selective developing countries for the years 2003 by applying a hypothesis which says that poverty may lead to more income variation and more rural poverty in developing countries .The research aims at studying this relationship and to have an answer for the following question :Can an agricultural growth be achieved with the existence of large variation in income distribution ?The statistical results by using the simple square method f two stages 2SLS appeared the positive and significant relationship for the variance of agricultural work to the total work X2 and inflation rate X4 in affecting Gini Coefficient .The increase in value X2 & X4 by 20.6 and 0.41 units respectively and this will produce effects with the same direction in increasing the variance level for distributing in come .The variance of agricultural work ratio to the number of population X3 has confirmed that it has negative and significant effect in Gini Coefficient throughout its index by 46.1 units .As for the increases taken place in Gini Coefficient it has produced small increases in the rate of annual agricultural product to the total domestic product .The value of index in Gini is estimated 0.10 units and shows that the growth of income distribution which represents Gini Coefficient participates actively in affecting rtes of agricultural product for a sample of studied countries .This will lead to an increase of rural poverty in a short term .

Abstract: This study was conducted in vegetable farm in the college of Agriculture and Forestry, Mosul University during 2003-2004 growing season to investigate the effects of two sowing dates: the Sept.20th and Oct. 20th, two planting methods of seedling: plots and furrows and with the application of nitrogen fertilizer (Urea 46% N) at rates 0 and 60 Kg/Donnum applied at two doses with three methods of splitting: 1- Half of the total amount was added after two weeks from transplanting and the other half was added at 21 days prior to harvest (30 + 30Kg Urea /Donnum). 2- One third of the total amount added after two weeks from transplanting and the other two thirds was added at 21 days prior to harvest (20 + 40Kg Urea/Donnum). 3- Two thirds of the total amount added two weeks from transplanting and the other one third added at 21 days prior to the harvest (40 + 20Kg Urea/Donnum) on growth, yield and quality of lettuce cv. Paris Island. The experiment consisted of 16 treatments conducted in the field in a factorial experiment within split plot using the Randomized Complete Block Design with three replicates. Results indicated that vegetative growth i.e. leaf number/plant, leaf area/plant, head circumferences and mean weight of marketable head were increased significantly by second sowing date (Nov. 20th), plot planting method as well as by applying nitrogen fertilizer, while the methods of splitting of nitrogen fertilizer had no significant effect on most above mention characters. A similar favorable effect of second sowing date (No.20th), plot planting method and applying nitrogen fertilizer on yield characters was obtained at harvest, However, it has increased significantly folded head percentage, total and marketable yield, whereas the percentage of bolting plants only decreased significantly by second sowing date. The interaction among sowing date, plating methods, nitrogen application gave positive and significant increase in the total and marketable yield.
Abstract: In this research we've studied the effect of Some Pre-Treatments on the germination of Coriandrum Sativum L. seeds such as surface and planting at 2.5cm depth from soil surface as well as using the technology of pre-soaking with the following treatments : without soaking in water, soaking in Gibberellin with a concentration of 200ml.g/lit, soaking in water, soaking in ether petroleum, soaking in ethanol and soaking in concentrated sulfuric acid. Findings showed that the surface planting has improved seeds, germination and seedlings growth for all the features under study comparing with planting at a depth of 2.5cm. Findings of coefficient's overlap showed that surface planting and processing with Gibberellin with a concentration of 200ml.glit gave the best results. Seeds germinated early with an increased germination percentage which were 8.69 day and 75% respectively, as well as an increase in the fresh and dry weight of the root and green gross and an increase in the length of the longest seedling, then followed by soaking in water. Using the ether petroleum and ethanol showed no great significant effect on the features being studied; whereas the using of concentrated sulfuric acid showed a negative effect on germination for all features which were germination percentage 25.83 while which were concentrated 36.33%.
Abstract: The study was conducted to determine the effect of mulching on surface runoff under natural precipitation of Mosul city (Northern of Iraq). Standard flumes (100 x 30 x 12 cm) were filled with soil and treated with four types of mulching (weeded soil, weeded soil control, wheat straw and gravels). The flumes were exposed to the natural precipitation of 2004 – 2005 season. The result revealed that all rainstorms gave a significant amount of surface runoff depth and the treatments were ranked in the following order: weeds control soil > weeded soil > gravel mulched soil > wheat straw soil. Runoff threshold values were determined graphically and showed some variation Among the treatments. The calculated runoff efficiency of the studied treatments showed that wheat straw gave the lower value while the weeded soil control offered the highest value of runoff efficiency.

Organoleptic properties analysis including total volatile nitrogen, free fatty acids, water holding capacity and pH were performed each 30 days. Results showed that Brazilian chicken meat contain higher total volatile nitrogen and free fatty acids comparing with other kinds of chicken meats where as pH value and water holding capacity were highest in Domestic comparing with Turkish and Brazilian chicken meats. While there are a significant (P<0.05) decrease in water holding capacity, pH and a significant(P<0.05)increase in free fatty acids and total volatile nitrogen with increasing of freezing period for all kinds of chicken meats.
Abstract: The effect of using some food additives like ascorbic acid, nitrate and nitrite , sodium phosphate, lactic acid and acetic acid with different concentrations upon some chemical characteristics of local manufacture basturma during storage within open climate temperature from March to June, was studied. Significant differences were found in the values of the moisture content of different treatments of the stored basturma during storage period. The moisture content of stored basturma decreased simultaneosly with the increase of storage period which led to increase of protein and fat ratio significantly. Treatment with ascorbic acid resulted in the decrease of moisture content and the increase of protein quantity and slight changes in fat content during storage period. An increase in the ratio of protein was appeared when nitrate and nitrite were used. Generally, the use of sodium phosphate led to maintaining of the moisture content of the stored basturma during storage. The treatment with 5% of lactic and acetic acid did not affect significantly on moisture content in comparison with control and significant increase in protein content
Abstract: Isolation and purification of fungus which contaminated four species of citrus fruits which are orange , grape fruit , sweet lemon and sour lemon . Isolated fungus characterized , Penicillium digitatum , Althernaria citri and A.crassa used in this study because they were the most spread species in studied citrus fruits, The flasks stored for four weeks at ambient temperature with the presence of sodium benzoate with different concentrations. Values of PH and number of each of three fungus in all treatments were measured . Results showed that p.digitatum had the most spread in the four kinds of citrus fruits except orange , then A.citri which had the most spread in orange . The three species of fungus affected significantly (p < 0.05) in increasing of pH value with the absence of sodium benzoate especially in the last week of storage , but the addition of sodium benzoate with concentrations 0.05 and 0.1 % lead to still pH value in the average of standard treatment (at Zero week) , an increasing in the number of the three fungus with the increasing of storage period in 0.0% concentration of sodium benzoate in the two kinds of juices especially P. digitatum wherever the numbers are 239.5 and 203 ×104 spores / ml of orange and grape fruit juices respectively , but the addition of sodium benzoate especially at 0.05 and 0.1 % were significantly decreased the numbers of the three fungus.
Abstract: This study was done to analysis three hundred and tow samples of vegetables salad from local markets to found the total and fecal coliform, molds, and salmonella, in addition to study the role of sodium hypochlorite on counts of above microorganisms after infusion and shaking the samples for 5, 10, and 15 minutes. The results indicated the total counts of coliform were arranged from 2.8 × 105 in tomatoes to 4.2 × 108 cell/g in cucumber. When the fecal coliform counts were at range between 1.1× 103 in tomatoes and 2.9× 106 cell/g in lettuce, and the molds counts were from 1.3 × 105 in cucumber to 3.4 × 106 in lettuce. The bacterial types of salmonella were founds in tomatoes, Onion, Cucumber, Capsicums, Lettuce, and Celery samples at 4.1, 6.5, 7.4, 8.3, 13.8, and 22.7%, respectively. The infused of vegetables samples in hypochlorite for 5 minutes were causes reduced the total counts of coliform which became arranged between 17 in tomatoes to 120 cell/g in lettuce, and the fecal coliform were only founds in lettuce, celery, and cucumber samples at 10, 12, and 14 cell/g respectively, Also the molds were at 13, 12, and 10 cell/g respectively. Where the salmonella types were not founds in any samples after treatment. The infused vegetables samples in hypochlorite for 10 minutes causes a sharp reduced and non found any microorganism in all samples unless in lettuce and celery were found total coliform at 22 and 8, fecal coliform at 4 and 3 and molds at 6 and 4 cell/g, respectively. The infusion of vegetable samples in hypochlorite for 15 minutes causes clearance the samples from all microorganisms.
Abstract: Brucella spp. causes Malta fever a zoonotic disease that can be transmitted to human by consumption of raw milk and unpasteurized dairy products like soft cheese, whose production is wide spread in Iraq. Because of the harm of this disease on public health and the difficulty of treatment; therefore this study included the isolation of Brucella from human (final host) and raw milk (the main source of infection). Two isolates were obtained, isolate (1) was isolated from (23) blood speciemens taken from patients showed clinical findings of malta fever and their serum gave high agglutination titer in Rose Bengal Test, the second isolate (2) was isolated from (37) milk sample collected from regions (Mahweer, Manarat Shabbak and Bartillah) from sheep suffered from abortion and their serum gave positive results with Rose Bengal Test. After the diagnostic biochemical tests were done, we found that as aresult these two isolates belong to the species Brucella melitensis. It has also been found that both isolates didn’t withstand the decreasing of pH in yoghurt, the results also showed the use of starter bacteria Lactobacillus delbreukii subsp. bulgaricus alone or with the combination of L. delbreukii subsp. bulgaricus with Streptococcus thermophilus gave effective results on the resistance of these two isolates in yogurt as compared to the use of S. thermophillus alone.
Abstract: This study was conducted to show the effects of each aflatoxins (AF) or activated sodum bentonite(AB) .Singly or combination in the following groups:1- animals fed Diet (AF) alone at 2.5mg/kg.2-animal fed died (AF)at 2.5mg/kgwith AB(5g/kg). 3-animals fed diet AB alone (5g/kg).The result show that the effect of AFB1 on physical characteristics were investigated. The toxin caused changes in the physical characteristics of milk. Viscosity, density, curd tension and acidity of the produced milk were significantly (p<0.05) decreased while the pH and coagulation time were significantly increased. Addition of ASB proved to have a positive effect on the AFB1-treated animals. physical characteristics became closer to the normal milk. Ceasing AFB1- contaminated feed consumption by the animals also resulted in physical characteristics of the produced milk to normal.

Abstract: Nine cultivars of durum wheat (Triticum durum Desf.) were tested for two years at Hammam Al-Alile on 1998 and 1999. Data on plant height, no. of days to heading and maturity,no. of spikes , no. of grains per spike ,1000 grain weight and grain yield were recorded and analysed for phenotypic and genotypic variances , heritability and correlations. Combine analysis exhibited significant differences between cultivars for all studied characters except grain yield. Cultivar X year interaction was significant for all studied characters except no. of days to maturity.High phenotypic and genotypic variances were found in plant height, no. of spikes , no. of grains per spike ,1000 grains weight and grain yield .Large environmental variability was observed in most characters except no. of days to heading and maturity and 1000 grain weight.High heritability estimations were found for all studied characters except grain yield and no. of days to maturity which gave low and moderate estimations respectively.Grain yield positively correlated with number of spikes in 98 and 1000 grain weight in two seasons.
Abstract: The study included seven parents of chickpea (Cicer arietinum L.) : Local, F85, F97-73c, Dijla, Marakishi, IPA69 and F97-158.The parents were crossed in a diallel fashion (excluding reciprocals) .The seeds of parents and F1’s were sown during the 2005-2006 season in the field of the College of Agric. & Forestry at Mosul University to estimate gene action. The additive variance (D) and dominance variances (H1 , H2) were significant for all characters but the dominance variance was greater than the additive variance values for all characters excepted 100-seeds weight. Dominance effect (h2), as the algebraic sum over all loci in heterozygous phase in all crosses, were significant for all characters except no. of pods per plant and biological yield .The values of average degree of dominance showed that over dominance effect controlled all characters except for 100-seeds weight . The ratio KD/KR was greater than 1 for all the characters. Values of K were less than 1 for all characters except no. of 90% maturation. High broad sense heritability ranged from (0.72-0.91) for all characters. Narrow sense heritability was high for 100-seeds weigh (0.62), and low for biological yield (0.18) and moderate for other characters (0.21-0.50).
