Abstract: Five maize genotypes (CMT 033066, CMT 033060, CMTQ 033072, CMS 983046, CMTQ 033070) were used in 5x5 diallel crossing with out reciprocals. Combining ability for some quantitative and physiological traits was studied. F1 hybrids and the parental genotypes were grown in a Randomized Complete Block Design with three replications. The analysis of data carried out according to Griffing (1956) Method 2 (fixed model). Significant mean squares due to genotypes were exhibited for all traits. Highly significant mean squares due to GCA was exhibited for all traits , except Photosynthetic rate which was found non significant. Also highly significant mean squares due to SCA was obtained for all traits except, photosynthetic rate, transpiration rate which was significant only and stomatal conductance was found not significant .The ratio 2GCA/2SCA was less than one for all traits, indicating the importance of non additive gene effect, with the exception of plant height which was more than one, indicating the importance of additive gene effect, and the average degree of dominance values was more than one for all traits, except plant high, indicating the over dominance gene effect role in controlling these characters. Heritability in broad sense was high for all studied characters, while in narrow sense heritability was high for plant height only, moderate for transpiration rate and stomatal conductance and low for the remainder traits.

Abstract: Pots experiment was carried out at the College of Agric & Forestry , Mosul University in summer growing season of 2003 to determine the percentage of germination and seedling emergence for Sorghum halepense L seed which developed from different positions on infloresence of mother plant in relating to different time of seed maturity . Data was subjected to the convertional analysis of complete Randomized Design ( C.R.D ) as a factorial experiment . Result indicated that the germination percentage had significantly reduced 60.1 % when the seeds matured at october comparing with the seed maturity at july . On other hand , Seed that had been taken from lower part of infloresence had less variability or less percentage of germination than those taken from upper part of infloresence . Dry weight of emergering seedling also reduced up to 35.7 % when it was collected at september than at August , while 18.6 had reduced in dry weight from the seeds had matured from the lower part of mother infloresence .

Abstract: This study was conducted in telefar region, Mosul governorate during agriculture season 2002-2003 to study the effect of three plow types (mold board , Chisel and one way disk) with two plowing depths (10-15 cm) and (15-20 cm) and two sprinkler irrigation system on soil physical properties (bulk density , porosity , moisture content and soil penetration resistance) randomized complete block design (split – split plot design) was used and the results analyzed statistically. The results showed that the one way disk plow with the solid set sprinkler irrigation system surpassed in bulk density and porosity after plowing.

After the final irrigation, the moldboard plow and the same plowing depth and the same irrigation system surpassed in moisture content characteristic.Also the moldboard plow with the plowing depth (10-15) cm with irrigation system surpassed in soil penetration resistance .

Abstract: Weevils were diet on various legume seeds had significant effects on their biological aspect processes. High mean of egg numbers was 69.6 eggs / female which lay on cowpea seeds, while in chickpeas were 40.2 eggs/female. Period 5.2 days, while the kidney bean gave the shortest period 4.2 days. The highest percentage of egg hatching was 90 % for the kidney bean seeds, while the lowest percentage was 80% in chickpeas. Lentil seeds produced the longest larval-pupal duration being 29.8 days, the cowpea seeds had the shortest period 23.3 days. Survival of larvae hatched from eggs laid on kidney beans stay died after a short time of hatching. The highest percentage of adults emerged was 81.6 % in case of feeding on cowpea seeds, while the lowest was 41.3% when the larvae grown on lentil seeds. Development of larvae on various kinds of seeds had significant effect on the adult longevity and the highest mean for female and male adults were 9.8 & 9.0 days respectively, for the larvae reared on cowpea seeds. While the duration is reduced to 5.1 days for females and to 4.2 days for males that produced from larvae fed on lentil seeds. The longevity of the females was longer than that of males in all cases. Significant differences in weight loss of applied pulses as continuous exposure for 4 months were concluded, which take 57.5, 48.3, 33.0, 8.8 & zero % for cowpea, green gram, chickpea, lentil & kidney beans respectively. The highly infested seeds of cowpea gave the lowest percentage of germination with an average of 8.8 % in comparison with that of non-infested 72%. The results indicated that the slices of garlic and four plant extracts were showed a high significant effects on the adult mortality for one day after treatment as follows : garlic slices > garlic extract > menthum extract>basil extract > celery extract >.

Abstract: Different concentrations of cold aqueous extract Ficus carcia leaves were studied on the levels of glucose, cholesterol, triglycerides, total lipids, Aspartate amino transferase (AST) and Alanine amino transferase (ALT) activity and total protein in the serum and in the liver glycogen level and total protein in the liver and heart of the normal rats. 25 male albino wistar rats derived were used, with age 3-4 month, and weight 225-300 g. The rats were divided randomly into five groups. The first group was injected with distilled water and consumed the control group. The second, third, fourth and fifth groups were injected intraperitonealy with 100, 200, 300, and 400 mg/kg B.W with aqueous extract of Ficus carcia leaves. The blood, liver, and heart tissues were collected. The statistical results showed a significant decrease in the glucose, cholesterol, triglycerides and total lipids. While a significant increase in the Aspartate amino transferase (AST) and Alanine amino transferase (ALT) activity was showed in group 5of both compared with the control group (P < 0.05). In the tissues a significant reduction showed in the liver glycogen, for all concentration of the injected extract while insignificant differences were showed in the liver and heart total protein compared with the control group (P < 0.05). It was concluded that the cold aqueous extract of ficus carcia leaves has a biochemical role in the regulation and controlling the metabolic reaction through decreasing the glucose and lipids levels.

Abstract: The antibacterial activities of Hibiscus sabdariffa and Quercus infectoria extracts were screend against 5 spicies of Gram negative bacteria, Pseudomonas aeruginosa, Escherichia coli, Serratia marcescens, Proteus vulgaris and Klebsiella pneumonia. Calyces of Hibiscus sabdariffa and nutgalls of Quercus infectoria were extracted in acetone using a soxhlet apparatus. Extracts of the plants showed high antibacterial activities on all types of bacteria tested using the disc diffusion method and comparing with the standard antibiotics Gentamicin and cephalexin . The combined effect of the two extracts was also studied against the tester bacteria, and found increase the inhibition zone diameters at all concentrations, except in S. marcescens which was inhibited at concentrations from 200-6.25 mg/ml and Pr.vulgaris which appeared more sensitive against the combination between the two extracts. The calculated inhibition zone reached 25 mm using the concentration 200 mg/ml which is greater than the control effects. The study also determined the Minimum Inhibitiory Concentration MIC of the two extracts and the combination between them. The bacteria also showed high sensitivity against the extract combination,with Pr. vulgaris was also more sensitive than other bacteria. The calculated MIC reached 0.0625 mg/ml meanwhile. K. pneumonia appeared less sensitivity, the calculated MIC was 0.125 mg/ml.

Abstract: Six traits of bread wheat in 15 F2 generation of crosses from 6×6 diallel mating system with their parents were studied. The relative efficiency over grain yield from selection based on several indices were calculated . The results indicated that there was an increase in efficiency of selection for yield from 12.986 to 122.372% in various indices, which indicated that a selection index based on combination of traits, including number of spikes , spike length, 100 grains weight and number of grains per spike was superior to all selection indices, therefore the selection based on these four traits is recommended.

Abstract: This study was conducted to investigate the effects of Thyme leaves( Thymus vulgaris ) on blood glucose, as well as, their reflection on body weight , mean body weight increment and feed efficiency in males and females local rabbits, and its effects on some reproductive characters, as testes and uterine weight and puberty age .The rabbits which were of 12 weeks old had been divided into 4 groups each 6 rabbits ( 2 replicates ) for males and females . Rabbits of 1st group ( males ) and of the 2nd group ( females ) were fed on the standard ration ( control ) , while the 3rd ( males ) and the 4th ( females ) groups were fed on standard ration containing 2 % thyme leaves for 10 weeks . And to determine the puberty age , 4 sexually mature males and 4 sexually mature females were used since the 6th week of experiment. Blood samples were obtained at the end of the 10th week. The results revealed a significant hypoglycemic effect of thyme leaves in both sexes which reflected significantly as an increase in body weight, mean body weight increment and feed efficiency improvement in both sexes ( females were better than males ), the treatment also causes a significant increase in uterine weight percent to body weight that leads to reduce the female puberty ages significantly.

Abstract: Survey carried under two different storing condition, showed that the incidence and severity of soft rot of potatoes were very high in none-cooled stores with the values of 28.92% and 0.11 respectively while the lowest was in cold storage with values 20.94% and 0.07 respectively. The following treatments were used in this study to control the disease: 1×10 4 cell/ml of Bacillus subtills, 10gm/kg of Halex 5ml/L of ciprofloxacin, 1ml/L of Bettanol, and 4% sodiume hypochlorate. All the above treatment lead to reduce the rate and the severity of the disease and to reduce the effect of the Erwinia carotovora on the stem high, dry weight of foliage and total weight of tubers per plant . the treatment with biological fertilizer (Halex) exceeded all the others in field and green house experiments . Reducing the rate and severity of soft rot disease in the storage foliage was cut before harvesting and when was near to mature, in two different dates (two and four days) after the last irrigation of the field. Harvesting the tubers after eight days after last irrigation from cutting the foliage led to reduce the rate and severity of soft rot of the tubers and severity of soft rot of the tubers in the cooled storage, with the values of 15.62% and 0.13, respectively. Curing of tubers after harvesting and before interning to the storage was achieved by leaving them in shadow for two or four days. The rate and the severity of tubers soft rot in the cooled storage with the values of 9.76% and 0.08, respectively.

Abstract: The study depended on a hypothesis that world trade organizations policies have various impacts on achieving food security levels in the developing countries in accordance with the economic structures and the level of their economic growth for the period 1975-2003. To approve this hypothesis a sample of the developing countries was selected including Egypt, Morocco, Tunisia, Jordan, Syria, Turkey, Thailand and Pakistan. Time series data were used in estimating the phenomenon under study for each country as they reflect the effects of World Trade Organization policies in achieving levels of food security. The following results were driven: Agricultural economic revealing variable contributed in increasing the agricultural gap value with (37.5%) of the sample countries and the other part of the effect was distributed between either negative or neutral in other states. Positive effects in direct foreign investment to total local product was (50%) of the agricultural gap for the sample countries and the negative and neutral effects were for other countries. The study recommends the following : Improving the competitive ability of the agricultural products in the local and international markets under the current economic transformations imposed by the World Trade Organization agreements by increasing the level of the agricultural production that is one of the pillars that economic integration should depend on in the developing countries. Separating economic work from policy through agreements to achieve Arabic economic integration partially and totally.

The type of hybrid as well had significant effect ( P ≤ 0.05 ) on the feed conversion where the birds of hybrid Cobb 500 were superior in this trait than those of Hubbard Classic , the feed conversion coefficient of two types of hybrids were (1.495 and 1.548 g feed intake / g weight gain ) during the starter period and ( 2. 067 and 2.120 g feed intake/ g weight gain ) during the growth period for both hybrid respectively.The mortality percentage was significantly low in Cobb 500 hybrid than Hubbard Classic during the total breeding period where was (2.89 and 14.88 % ) for both hybrids respectively .The results of yield factor of the total breeding period showed that significant differences to hybrid Cobb 500 vs Hubbard Classic revealed and were (269.8 and 214.42 ) for both respectively . According we can conclude that the hybrid Cobb 500 was superior in all essential production indicatory than Hubbard Classic .

Abstract: Experiment were carried out in field crops experiment location in 2006-2007 to investigate the effect of seed size and sowing depth on germination and seedling characters . Wheat seeds of Sham-6 variety were separated by size ( small , Medium , and large ) using standard sieves no. 7 and no. 8 . The seeds passed through sieve no.8 (2.36 mm) were small , while those passed through sieve no. 7 (2.83 mm) were medium , the seed retained on sieve no.7 were large . Seeds sown at 2 , 4 and 6 cm depth in plastic pots filled with loamy soil . The results demonstrate a significant predominance of large seeds in percentage and speed of germination , seedling elongation velocity , fresh and dry weight of seedlings and roots , tall of the longest root and the percentage of consumed food reserve in seeds . There is a significant decrease in no. of days to complement germination and occurrence of second leaf in 50 % seedling , there are markedly similarity between large and medium seeds . The seedling grown from 2 and 4 cm depths were predominance in most characters comparing with that grown from 6 cm depth . The interaction were significant in most characters , the general trend were the mastery of large seeds in lower depth in most characteristics , simple correlation coefficient was determined between all characters . This trail shows obvious differences in growth due to variation in seed size and sowing depth , so raising in seed size uniformity may achieve uniform growth which will reflect on final yield .
