The study was conducted in College of Agriculture and forestr y / Fields Department of Animal
Production during the period 1/9/2021 to 1/12/2021 , ejaculated were collected on 6 Awassi rams with
weight 45.63±1.32 kg and aged 1.5 – 2 year , dilution ratio was 1/16. Semen was collected from rams once
a tow week through the period of theexperimental using electro-ejaculator for semen .The experiment was
conducted to study the effect of magnetization of diluted semen (non-magnetic, magnetic of one hour,
magnetic two hours and continuous of magnetic strongly 1800 gauss) and preservation periods (24 , 48 , 72
and 96 hours) on semen characteristics ( mass motility , individual motility, pH of semen, percentages of
dead, live and abnormal sperm). The results indicated that the process of magnetizing the diluted semen led
to a significant effect (a ≤ 0.05) in increased the percentage of individual motility sperm , live sperm and
reducing the percentage of dead sperm. The period of cryopreservation (5 ˚ C) had a significant effect (a ≤
0.05) in decreasing the characteristics of the studied diluted semen and in increasing the percentage of dead
and deformed sperm. We conclude from the above that the magnetization of semen for an hour or two with a
intensity of 1800 gaus has a positive effect on the characteristics of the diluted semen, and that the advance
of the storage period (5˚C) has a negative effect on the characteristics of the diluted semen

This study was conducted during two seasons 2020-2021and 2021-2022 at two main different locations of
Sulaimani, and Halabja governorate; each with some sub-locations, to estimate green forage yield, dry forage
yield, dry matter percentage and animal unit. The result confirmed the highest plant height of grasses were
recorded in Sulamani location; however, Halabja location provided highest plant height for legumes for the
two seasons. In regarding to the effect of seasons on plant height, the second season was taller than the first
season for grasses and legumes. Maximum green yield, dry yield and dry matter percentage exhibited in
Sulaimani location for two seasons. Regarding seasonal effect, the second season exceeded the first season in
green and dry yields and dry matter percentage; Maximum total forage yield and animal unit in 3 months
provided maximum value by Sulamani location for both seasons. Results of chemical analysis for the grass
plants showed that there were differences between two locations. The Sulamani location gave the maximum
percentage of protein, phosphorus and calcium content. In which Halabja location was recorded maximum
value for carbohydrate, Potassium, and ash content for the first season. While for legumes, plants recorded
highest value for protein, phosphorus, Potassium, Calcium and ash content except carbohydrate content gave
high value at Halabja location. In the relevant of the effect of seasons on chemical components for grass plants,
the second season 2021-2022 predominated the first season in the chemical contents of protein, carbohydrate,
phosphorus, potassium, calcium and ash. Whereas for legume plants the second season also gave maximum
value for all contents, excepted protein content recorded high value in the first season

This study was conducted to investigate the effects of random and controlled traffic of farming machinery during the agricultural operations on some mechanical and soil properties. The indicators that related to agricultural tractor (mechanization indicators) were draught capacity, fuel consumption, depth stability ratio; and Soil Bulk Density (SBD) was also measured before and after the experiment. The experiment was conducted during the spring agricultural season of 2022 in one of the farms that located about 30 km Northwest Mosul city - Nineveh Governorate - Iraq. Randomized Complete Block Design (RCBD) was used for data analyses with four replications (n=4). The experimental site was divided into two main blocks based on the investigated factors (1) tire pressure (8 psi) and (15 psi); and (2) number of traffic (no pass, one pass, two passes, three passes). These factors were studied at two different soil textures (clay soil, silty loam soil). Duncan's multiple range test was utilized to compare between the means at a 5% probability level. The results showed that Controlled Traffic Farming (CTF) system represented by zero-traffic has achieved the best values (P< 0.05) for all studied indicators. Soil bulk Density was significantly better with no-pass system compared to the one-pass, two-passes and three-passes, at approximately 16%, 19% and 20%, respectively. Energy requirements when using CTF system (no-pass) were also reduced by 29%, 33%, 41% compared to the one-pass, two-pass and three-pass system, respectively

Soil compaction is one of the main problems that many agricultural lands facing globally. Soil compaction is affected by several factors, the main of which are soil moisture and the applied pressure on the soil as a result of the of agricultural machinery traffic. Therefore, this study was aimed to find out the effect of soil moisture content and tractor traffic on studied indicators (drawbar power, fuel consumption, slippage percentage, specific energy, soil resistance to cutting and shaping, dry bulk density, porosity), The experiment was carried out in the autumn agricultural season (2021-2022), in one of the fields of Wana sub-district (the village of Qara Kharab) of the Mosul district, which is about (20) km away from it. The field was designed according to Randomized Complete Block Design (RCBD), the factor experiment managed based on split-split block design with four replications. The main plots were allocated to soil moisture with two levels (17-20)%, and sub-plots were allocated to farming systems at two levels also (Random Traffic Farming (RTF), Controlled Traffic Farming (CTF)), Duncan's multiple-range test was used to compare the means at the (0.05) probability level. The results showed that moisture content of 17% compared with 20%, significantly reduced soil resistance to cutting and shaping and fuel consumption by (40%, 49%) respectively. CTF compared with RTF, significantly decreased the power requirement indicators by (15%, 27%, 30%, 31%,32%) for slippage, specific energy, fuel consumption, drawbar power, and soil resistance to cutting and shaping, respectively

The experiment was conducted in the year 2021 – 2022 in one of the fields of the College of Agriculture and Forestry, in the district of Mosul / governorate of Nineveh - Iraq.
The topography of the field was characterized by its flatness, and the soil was of a (clay) texture. The research was conducted with the aim of studying the effect of
Three factors to add fuel improved type (diesel smoke stop ) from the German company (LIQUI MOLY) subsoiler plow wing vibration and Three speed for the engine ( 1000 &1500 & 2000) r/min, to know the effect of this on the farm tractor driver’s seat vibration and noise characteristics.
Actually experiment was conducted using a ( Randomized Complete Block Design ) and plates system
( Split – Split plot design ) On this basis, the experiment was divided into 12 treatments with (3) replications for each treatment and 36 experimental units, and the length of the treatment was (90 meters) and with a constant plowing depth (40 - 45 cm). using Duncan's multiple range test at the 0.05 probability level to test Significant differences between the averages of different treatments .The results indicated that there were significant positive data for all traits, using enhancer fuel compared to without the enhancer.
The results showed a significant increase in the vibrations of the driver's seat
Agricultural tractor and noise with vibration of the wings of a plow subsoiler. However, the driver's seat vibration values remained for vibration subsoiler plow wings within the directive of the European Parliament and the European Council and the measurements approved by ( ISO 2631-5 in 2004) Besides, increasing engine speeds led to increases noise, and vibrations under the seat of agricultural tractor driver, as well as the results indicate the superiority of the fuel added to it enhancer and vibration wings at all tractor speeds of engine to record the lowest vibration ratios for the agricultural tractor driver's seat. Through the study, it can be concluded that the addition of enhancer to diesel fuel led to improvement tractor performance of agricultural tractor.

Preserving the crops seeds is very important procedure to the farmers and breeders. Because it’s
reducing the contamination of these seeds with the aflatoxin during the post and pre harvest the crops.
The Current study was carried out in October 2019, in the crop production department, Agricultural
research center in Sulaymaniyah province. Fifteen Kg of local wheat (Slemani) was provided from
the crop science department. Five levels of garlic powder was used (0, 2, 5, 10, 15)% to find suitable
concentration during the storage seed. The samples were taken for in three times (1 day, 6 months,
and 18 months) to test the seed contamination with toxins and calculate the seed germination. Our
result show there is significant effect (p<0.05) of adding garlic powder with 15 concentrations on the
T2 toxin. In conclusion its possible to use the garlic powder with 15% for reducing the effect of toxin
in storage wheat seeds.

The research aims to analyze the impact of transaction costs resulting from the
purchase of haulers in a deferred payment method on the profitability of wheat and barley
farmers in the province of Baghdad. To achieve this goal, a stratified sample was selected that
included 150 farmers of wheat and barley farmers in the governorate, and the data was collected
through a questionnaire form prepared for this purpose. The research followed the descriptive
and quantitative method in analyzing the data and extracting the required results The results of
the logistic regression analysis showed that some elements of transaction cost such as
uncertainty and privacy have an important role in choosing the futures market for agricultural
pullers. The results of the multiple regression of the estimated farm profit model for drawers’
services also showed that the purchase decision in terms of transaction costs had a significant
effect on the farm profit of the studied sample. The research recommended the need to reduce
privacy, as it directly affects transaction costs, and the implementation of the agreed terms of
the contract should be adhered to according to their agreed timings, as the increase in the feature
of uncertainty directly affects transaction costs
