A field experiment was carried out to evaluate the effects of different nitrogen levels on four promising bread wheat genotypes. The experiment was conducted at the farm of Field Crops Dept., College of Agricultural Engineering Sciences, University of Duhok in winter season 2020-2021. The experimental units laid out in factorial experiment with (R.C.B.D) with three replicates. Four genotypes were used (Bora, Jehan-99, AApast-36 and AApast-26) and four levels of nitrogen (0,75,150 and 200kg ha-1). The result revealed that the growth parameters respond significantly to nitrogen fertilizer. Application of nitrogen levels in combination increase yield, gave the highest grain yield 219.1 (g) at 200kg ha-1 nitrogen, also the highest grain (231 g) was recorded from AApast-36 genotypes. Among the interaction of nitrogen levels and wheat genotypes produced the highest grain yield (266.6g) per plant at 200kg N ha-1 and Apast-36 genotypes. The Apast-36 genotype was superior in flag leaf area 48.14 cm2, Number of seed per plant 42.8, weight of seed spike 1.88g and 1000-seed weight (43.73 g). So that this genotype can be considered an advanced line and can be placed in a breeding program. Most of the studied traits are highly correlated with yield such as 1000-seed weight (0.91), spike length 0.52 and number of seeds per spike 0.45 and it can be said that these traits are the important effective components in seed yield.

Hydropericardium hepatitis syndrome is an acute infectious disease of broiler chickens characterized by high mortality, accumulation of fluids in the pericardial sac and necrosis of hepatocytes, during 1987 the virus was isolated from chickens in Angara near Karachi city in Pakistan and the disease takes it is name of this city. It is reported in China in 2015 in birds of 3-6 weeks in broiler chickens causing sudden death with high mortality reaches up to 75%. Avian adenovirus divided into 3genrea: Atadodenovirus, Siadenovirus, and Aviadenovirus the last one divided in to 5 species A to E subgroup1 strain 4 causing (Hydropericardium hepatitis syndrome). Subgroup 2 causing turkey (hemorrhagic enteritis, marble spleen disease). Subgroup 3 causing (Egg drop syndrome EDS). strain D and E produce inclusion body hepatitis while strain 1 causing (quill bronchitis). outbreaks of the disease producing economic losses for the poultry industry. Both vertical and horizontal transmission have an important role in the spreading of the disease. gross examination of the liver showing friable, enlargement, paleness of the liver. the kidney is swelling and hemorrhage with pale areas of necrosis in the parenchyma, pericardium is filled with clear or jelly fluids but histological changes showing hepatitis, nephritis and presence of basophilic intranuclear inclusion bodies. There are many tests can be used for the diagnosis such as PCR, ELISA, neutralization test. We concluded that the disease has economic importance due to high mortality and high losses of chicken’s meat production, so, biosecurity and vaccination are essential for preventing the infection.

Onion (Allium cepa L.) is one of the economical cultivated crops and is consumed heavily worldwide. The demand fOnion (Allium cepa L.) is one of the economical cultivated crops and is consumed heavily worldwide. The demand for onion seeds is high as it loses viability within a year. In Iraq, onion production has been limited due to the lack of good quality of seeds. Therefore, this study was aimed to improve seed quality and productivity of onion local white cultivar by using optimum onion sets size and priming with phytohormones. A field experiment was carried out in the Grrdarash field belonging to the Salahaddin University, Erbil. A split-plot in Randomized Complete Block Design (RCBD) was applied with three replicates. Onion sets >6.0 cm, large diameter and 4-6 cm, medium diameter, was selected. The bases of the sets were soaked in ascorbic acid (AsA) (1 and 2 mM), salicylic acid (SA) (0.5 and 1 mM) and control (water only) for 24 hours at 4°C. The results show that the emergence rate of flower stalk per day, the rate of umbel opening per plant, the number of flower stalks per plant, the number of flowers per umbel and seed yield (t.h-1) were increased statistically and significantly by using the large onion sets. AsA and SA treatments show their significant effect on flowering and seed quantity. A positive relationship was found between the aforementioned treatments and onion seed yield. Therefore, further studies are required to evaluate the effectiveness of a natural product that has the same properties as AsA and SA on the growth and quality of vegetable crops.

Animal health depends on multiple factors, and recently it has been shown that diet plays a major role in maintaining health and preventing various diseases. One of the most important nutritional factors is antioxidants, which occupy a special place because they play an important role in animal survival, maintaining animal health, and improving its physiological and productive performances and the immune state of the body. Antioxidants work to reduce the harmful effects of free radicals and toxic products of the metabolism. Therefore, the role of antioxidants, especially antioxidant vitamins (vitamin A, E, and C) is important in the growth stages of the bird's body, as well as in reducing the stress of birds as a result of their rapid growth requirements. Poultry products are considered one of the most protein sources in human nutrition in order to solve the problem of food shortage in the world, so the poultry industry is taking many ways to reduce the time period to reach the marketing weight such as: genetic selection, nutritional improvement, and other environmental factors, but unfortunately, all of that is associated with reduced immunity and the occurrence of oxidative stress. Therefore, the aim of this review is to clarify the role of antioxidants, which are: vitamin A, E, and C in the physiological and productive performance of broilers and their ability to prevent and/or reduce the oxidative stress effects in the body.

The basic principle of Ohmic heating is the conversion of electrical energy into heat energy, resulting in internal energy generation. In this study, an experimental batch Ohmic heating unit was designed and manufactured. The effect of voltage gradient of alternating current during batch Ohmic heating on orange juice was investigated. Parameters such as temperature, electrical current, time consumption, system performance coefficient, and heating rate of orange juice under the Ohmic heating process were studied. The time consumption such as (23.02, 11.25, and 2.19 minutes) to reach Ohmic pasteurization temperature (95 °C) was decreased as the voltage gradients (9.20 V/cm, 12.64 V/cm, and 25.28 V/cm) increased respectively. The electrical current was rapidly increased (4.46 Amp.) in accordance with the higher voltage gradient (25.28 V/cm) to attain the pasteurization temperature. With rising voltage gradients, Ohmic heating resulted in greater system performance coefficient values. The heating rate appears to have grown dramatically as the voltage gradients increased.

Blood glucose response and Glycemic Index (GI) of diets containing different sources of carbohydrate including glucose, starch, amylopectin, bread, rice, whole wheat kernels (habbiyah), lentils, check peas, kidney beans, and mixtures of bread or rice with lentils, chick peas or kidney beans for healthy Sprague Dawley rats using glucose as standard were studied. Fifty five normal animals were housed individually to perform this study. Animals were fasted (overnight fasting) for 12 hours and tested for blood glucose at zero time before given in amount of test food containing 0.15 g carbohydrates. Blood glucose was determined after 15, 30, 45, 60, 90 and 120 minutes. Results showed that amylopectin based diet had the highest GI (96) comparing with lowest GI (44) for habbiyah based diet. Results also show that addition of lentils, check pea or kidney beans to the bread resulted in lowering the GI of the final meals from 70 to 46. However, addition of these legumes to the rice base diet did not enough reduce the GI. In conclusion, mixing different sources of carbohydrates might be change the blood glucose response and GI of the original foods.

Afield experiment was carried out during the winter seasons of 2008-2009 and 2009-2010 in Salamya which is located at 34 Km southern from Mosul city. The split plot arrangement in Randomized Complete Block Design (R.C.B.D) with three replications was used. The experiment included four levels of biofertilization EM1 (0, 1, 2, 3 cc/Liter), five levels of nitrogen fertilization (0,30,60,90,120Kg N/ha). Nitrogen fertilization levels and biofertilization EM1 were represented as Main plots, and sub plots respectively. The results indicated that biofertilization EM1 level 3 cc/Liter was significantly superior in all growth traits and yield in both seasons with the exception of harvest index in first season it was significantly superior in stem length, leaf area, biological yield, number of spike per m2, spike length, number of grains per spike, weight of 1000 grains, grain yield,protein percentage and yield.Nitrogen fertilization level 120Kg N/ha was significantly superior in all growth traits and yield witch is stem length, leaf area, biological yield, number of spike per m2 , spike length, number of grains per spike, weight of 1000 grains, grain yield, harvest index,  protein percentage and yield in both seasons . Biofertilization EM1 and Nitrogen fertilization interacted significantly for all growth and yield characters in both seasons, biofertilization EM1 level 3 cc/Liter and Nitrogen fertilization level 120Kg N/ha  interaction was significantly superior in all growth traits and yield in both seasons with the exception of harvest index which was at the interaction between biofertilization EM1 level1cc/Liter and nitrogen fertilization level 120Kg N/ha.
