Abstract: The experiment was conducted during the Agricultural season 2008 in the green house of Field crops .Dept , College of Agriculture and forestry. The effect of different dosses of glyphosate (48 , 96 ,144 ,192 ml/ha) with different durations time of herbicide application after (10,20,30days) of plant clover infestation were studied . Dodder can competes strongly with clover , potentially reducing clover growth . Fresh and dry weights of dodder were decreased at the first and second durations of herbicide application . The height of plant & no . of beanches were significantly higher at the first duration whears the dry weight of stems, leaves and roots were significantly decreased as the time of application increased . On the other hand , fresh and dry weights of dodder plants were reduced as the doses of herbicide increased . Clover plant height and no . of branches were increased as the glyphosate doses increased .Dry weights of leaves , stems and roots were inversely related to the dose of glyphosate Fresh and dry weights of dodder were negatively related to the dose of herbicide at all durations of herbicide application . The results of the present study showed that glyphosate caused a cleare damage on dodder plants where as clover plants did not obtain any sign of damage had less effect on it .

Abstract: The purpose of this descriptive study was to get some information about teaching clarity at the college of agriculture-Mosul University. 692 students participated in responding to an instrument designed to measure their perceptions of teaching clarity of 76 agri–science teachers, and its reflections on their academic achievement. The study pointed out that a considerable proportion of agri-science teachers have a low teaching clarity resulted from low performance on the instrument items as perceived by their students. The results also showed that, students' achievement of high clarity teachers were better than students' achievement of low clarity teachers. Based on the findings, it is important to develop an agricultural education curriculum, which include a courses relevant to their common career as an agricultural instructors.

Abstract: Economic stabilization and structural adjustments are among the important programs adopted by economic policies in the developing and Arabic countries. These programs deal with the structural imbalances in economic sectors. In this study concentration is laid upon dealing with imbalance in agricultural sector in Yemen, Syria and Saudi Arabia. These countries are selected as a sample representing the Arabic countries in their intellectual and source differences. Similar structural variables with some differences in the economic model are also used where due to the priority of dealing with these economic imbalances in agricultural sectors in each of these countries have been differences in the nature of dealing with these imbalances. Analysis had depended on acomparison between pre and post economic reform for the model of using similar variables for the two periods to identify the negative or positive changes in these variables after adopting reform programs. The study has showed that there were positive indicators in some variables after adopting economic reform while some of them remained unchanged, as in Yemen, for example. For Syria this approach has some negative effects especially for type of change in agriculture contribution rate in gross domestic production. In Saudi Arabia where no change has been noticed in type of change in agricultural product value (structural variable) positive aspects of adopting reform programs include the change of index number of food products prices and the index number of agricultural production per capita from non-significant to significant variables

Abstract: The research depended on remote sensing techniques and geographic information system (GIS) to study of running water in Tallafar, which is used to irrigate orchards, and agricultural land south of the city, due to technical importance in the compilation of information and data to monitor land resources and the changes that happened to it, including soil degradation. The samples has been taken from the water stream for three years ( 2009, 2010 and 2011) of same locations, same analysis on soil samples for each year, which had been irrigated by this water were conducted. The results showed an increase in sulfate concentration in all the locations that reached 37.18 meq / L as a highest concentration. The values of electrical conductivity of water samples in the studied area ranged between 2.82 - 4.38 dS/m. Also an increase in calcium ions value at the first location were noted, which was 30 Meq/ L in 2011. Through ERDAS program we found that there is a distribution of gypsum soils in the study area especially that appeared in large areas south of the orchards, also with relatively distribution around the horticulture land. The morphometric analysis for WMS7.1 program showed that all the water in the basin comes from the northern west plunge Zambar anticline and southern east blunge of Sasan anticline, as well as running water inside the city, which is flow in to waterway that is leading to the orchards and agricultural lands.

Abstract: Eight soil pedons were chosen. in Nineveh Province to determine the effect of physiochemical factors 0n pedogenic distribution of manganese extracted by DCB method.

(11.6-35) mg.Kg-1 respectively. Soil depth had significant effect in Al-Fadhlia & Al-Hamdania regions with ratio effect of 30% . 50% respectively. CaCO3 had a significant effect in Al-Hamdania region only. Organic matter had a slight effect. Soil fine fraction (silt & clay) had unclear effect in which manganese ranged between 37.2-39.52 mg.Kg-1in Al-Hamdania region. Soil pH had non-significant effect on manganese pedogenic distribution in studied soils. DCB was effective extracting method for Mn-Fe concretions and thin black coatings on red and green mudstone.

Abstract: Sodium quantity/intensity curves were applied for exchangeable isotherm system Na+ - Ca+2 suggested by Beckett by using thermodynamic parameters to evaluate fertility status in some rain-fed soils in Nineveh province / northern of Iraq. Results indicated that all studied soils were of neutral pH with appreciable total and active carbonates content of 182-270 , 63-91 gm.Kg-1 respectively, with dominant of chloritized semictite and illite clay minerals in soils clay fraction. the values ranged widely from 0.25×10-3 - 0.94 ×10-3 mole.L-½, the labile pool of potassium values ranged from 10.91-25.36 c.mole Kg-1 , while sodium potential capacity values from 24.76- 42.18 c.mole.(Kg.mole-1)-½.. On the other hand Gibbs free energy values- ∆G were negatively spontaneous reactions and ranged from -7.91 to - 0.6 cal. mole-1 and Gapon selectivity coefficient values ranged between 1.32 - 2.99 L.mole-1. Lacked in the curvature commonly seen in the quantity/intensity curves for sodium. Result showed lower values and higher energies of replacement of calcium by sodium, also showed a higher affinity for than . They also indicated that Na held in these soils in two characteristics types of exchange sites having different affinities for sodium.

Abstract: This study was conducted to reveal the conditions and parameters which control dissolution and release of indogentic potassium in some Hammam Al-Alil soils northern Iraq, representing Aridisols order. Three pedons were selected having different soil series namely (462CCE, 453CCW and 451CCW). The study included using successive extraction with 6.25M HCl, under reflux conditions for 100 mint. to determe the amount and rates of release exchangeable and non-exchangeable potassium in some calcareous soil periphery of semictite and illite minerals according to the amount of release of mica-K. by using a kinetic diffusion parabolic equation. The results showed that amount of released potassium was reduced by increasing extraction time, and the variation in chemical, physical and mineralogical properties of the soil samples have a great effect on each amount, rate, and pathway reaction of potassium release between soil series, also the results showed that the pathway reaction of K-release consist of two segments according to the parabolic diffusion equation. The first segment represented exchangeable phase that was more than the second phase (non-exchangeable) in its amount and rate of release . Fertility evaluation of the results according to amount and rate of K-release from mica-K referred that all soils samples has a moderate reserve with low release rate, therefore the K-reserve of soils could be mapped by soil series using this method of classification such mapping would provide data on the extent availability of reserves in both short term (i.e.) the crop over a growing season and long term.

Abstract: Nine Awassi ewes with an average body weight of (59.41 ± 5.29 kg) (4-5) year old were divided into 3 groups each of 3 ewes and fed for 15 days on one of 3 rations to study effect of using different levels of sodium bicarbonate on nutrients digestibility and some rumen parameters in Awassi ewes . All groups were fed rations consisted mainly of barley. wheat bran and soybean meal. The first group (control) was fed without sodium bicarbonate . while the other( 2 and 3) groups were fed on different levels of sodium bicarbonate (1.5 and 3%) respectively. All rations were iso calory and iso nitrogen. During the last three days after the pre period which lasted 15 days feces was collected and samples of rumen liquor and blood were taken. The results indicated that the different levels of sodium bicarbonate had a significant improvements(P < 0.05) on crude protein(69.56.73.42.76.64%) and crude fiber digestibility(52.63.58.41.62.35%) as the levels of sodium bicarbonate increased respectively. The results indicated that the levels of sodium bicarbonate had no significant effect on dry matter.organic matter and ether extract digestibility. Moreover. the results showed that the levels(1.5 . 3 % ) of sodium bicarbonate had a significant effect(P < 0.05)on pH rumen liquor( 5.17 . 5.83 . 6.32 )and bacteria concentration logarithm (11.34.11.47.11.78)/ml of rumen liquor respectively. Blood samples analysis showed that treatments had no significant effects on concentration of total protein. AST. ALT. urea. glucose. triglyceride. But the results showed that levels of sodium bicarbonate had a significant effect(P < 0.05)on blood cholesterol( 117.03. 126.33. 126.67 mg/100ml) respectively.

Abstract: Sweet and sour (salted or unsalted) whey protein concentrates were used after acetylation with acetic anhydride or succinylation with succinic anhydride at 0.5 %.to improvement of rheolgical properties of wheat flour products. Acetylated and succinylated gaved the best result their for used in dough treatments. Using farinograph appeared that acetylation of whey protein concentrates at 0.5% and addition them to the dough at 15% caused an increase in water absorption and dough stabilitiy. however.adding them at 40% showed the least values. Addition of these concentrates at 40% showed an increase in dough appearing time when compared to adding the concentrates at 15 and 30%. Results from extensograph indicate that using acetylated sour unsalted whey concentrates at 30% gave the highest values in elasticity properties. while adding them at 40% led to lowest resistant property and sometimes led to zero BU.Also addition of the concentrates at 40%gave the lowest resistant/elasticity ratio in all treatments while adding them at 30% gave the highest ratios. Addition the acetylated sour salted whey protein concentrates at 15% resulted in the highest energy compared to other treatments. Maxmum resistance was obtained when the concentrates added at 15% in all treatments and the incubation period of 90 min.

Abstract: Sweet and sour (salted or unsalted) whey protein concentrates were used after acetylation with acetic anhydride or succinylation with succinic anhydride at 0.5 % to improve the functional properties of dough. The addition of sweet salted whey protein concentrates and acetylated at 0.5% and added at 15% to the dough resulted in highest values of loaf volume and spongyness while when used at 40% it gave an unacceptable results. This indicates that addition of these concentrates was best at 15% of the dough followed by 30% then by 40% for all the treatments. Sensory evaluation indicates that the loaf made from doughs with the addition of ace- tylated and succinylated at 0.5% and added at 15% to the dough gave the best res ults for all the studied properties followed by 30% addition while at 40% addition was the lowest and the loaf was unacceptable.

Abstract: Whole sheep milk cheese was used to produce processed flavored cheese with 30 % +-1 fat level after mixing with low fat filing materials such as crud. labanah and skim milk powder. as well as cheese emulsifiers of 1:1 sodium phosphate and citrate. Wild garlic. cumin. nigella and cordomon of 1% were used as flavoring materials. Processed cheese samples were subjected to chemical. bacteriological analysis and sensory evaluation. After storage for two months at room and refrigerator temperature. The results showed that fat. moisture and lactose were decrease while total and soluble nitrogen were increased during storage period. Storage at room temperature had a significant effect on the values compared to refrigerant temperature. Results also shoed that flavoring materials had no effect on chemical composition while wild garlic have the effect in preventing the growth of microorganism .cordomon had the lower effect on microorganism . Results also showed that wild garlic was preferable for sensory evaluation. The effect of filling naturals on bacteriological content reverted that labanah had the lightest bacterial content while skim milk powder had the lowest count. On the other hand. using curd in the processed cheese gave the highest scoring evaluation.

The dry weight decreased at increasing cutting in autumn , the number of narrow and board leaf , dry weight were decreasing when increasing cuttings , the branch of plant was increased with increasing the cuttings in the two seasons . Dry yield increased at secont cutting in autumn season but in spring season the increase was found at the its cutting .

Abstract: The results of the statistical analysis indicated the existence of significant difference in the mean of the percentage of loss in cotton product according to the variety of cotton used in study, The mean of this rate for the varieties Cooker and Montana significantly Exceeded the means of the other types expect the variety sp as the difference between them was not significant, while the correlation was positive and insignificant (+0,53) between the percentage of loss in cotton product and the quantity of loss in other varieties of cotton, The date of planting did not have a responsible effect on the general mean of the quantity of loss in cotton product, The mean of the percentage o loss for the correlation of fertilizing with other minor elements was significantly more than all the mean of the other treatments expect fertilizing treatment with minor elements and spraying with leaf fertilizer. The value of economic threshold reached 2,51 – 2,85 larva/plant on purchasing insecticides for commercial prices, while it ranged between 2,05 - -2,15 larva/plant on purchasing insecticides for official prices. Concerning the effect of field treatment with insecticides (Confidor, Medamec, Endosulfan) on the quantity of cotton Al-zahr yield, the study indicated that the product of one-dounm of the cotton in the piece of land treated with insecticides reached 1290,84Kg/donum, while this production reached 818,92kg/donum in the piece of land not treated with insecticides. The production mean of one plant of Al-zahr cotton in the first harvesting in Al-Rasheediyyah reached 77,22 gram, 71,76, 71,66, 116,11, 115,92, 85,51gram/plant for the variety Cooker, Lashata, Montana and Dunn 1047, strain B, sp successively,The study also indicated that treating cotton seeds of Lashata variety with Cruiser insecticide led to an increase in the yield of Al-zahr cotton (138,88 gram/plant).

Abstract: The present study indicated that the effect of infestation and population density of saw toothed grain beetle on the physical characteristics and chemical components of some local rice variety Anbar , Aqrawi , Bazaini and imported American , Viatnami , Thailandi under the effect storage period 2and 4 months and level infestation 10 ,20 , 30 insect . Generally , the results appeared that the value of seed hardness , weight of 1000 seed and volume of 100 seed were decreased at the storage period 4 months than 2 months , also at level infestation 30 insects than 10 insects , According to chemical component , it was noticed that the percentage of carbohydrate was increased at increasing level infestation from 10 – 30 insect and storage period from 2 – 4 months , the value of another components like protein , oils and ash were fluctuated increasing or decreasing under the effect of the pervious factors .

Abstract: The results of studying the effect of 1. 4. 7 and 9 % concentrations and 0.1 . 0.3 mL dose of water extracts of Myrtus communis L. Ruta graveolens and Mentha piperita L. on mortality. attraction and repellent to larvae of Plodia interpunctella (Hubn.). showed a different variation in mortality. attraction and repellent percentage to the larvae according to the kind of extracts. concentrations and doses. The concentration 9 % of R. graveolens showed a highest mean mortality reached 74 %. and the relative toxicity reached 0.63 . 0.71 and 1.0 for M. communis . R. graveolens and M. piperita respectively and the relative efficieny values reched 157.44% for R. graveolens. 100% for M. communis and 132.14% for M. piperita. The results also revealed that the highest mean of attraction reached 46.67 by M. piperita at 1% concentration and 0.1 ml dose one hour after treatment followed by M. communis extracts which reached 46.67% at 9% concentration and 0.1 ml one hour after treatment. the M. piperita extracts produce a supreme repllent effect reached 36.67% at 9% concentration and 0.1 ml Dose one hour after treatment statistical analysis results showed a significant variation in balance values according to the extract concentrations. doses and time from treatment.
