he research aims to identify the most important determinants of agricultural
investment in selected Arab countries during the period 1995 -2016. It is necessary to
identify the agricultural investment and its importance and the specific factors affecting
it during the study period. What are the implications for the agricultural sector of the
countries of the research sample? The determinants of investment, which led to asignificant reduction in these variables (size of agricultural loans, inflation, surplus or
deficit in the budget, exchange rate) and investigate the impact of these factors on the
volume of agricultural investments in Iraq, Egypt and Syria. The descriptive side, which
was based on previous and contemporaneous studies that dealt with the same subject,
the quantitative second, which was based on econometrics through the use of the
multiple linear regression model, and thus the economic interpretation of the results of
the quantitative analysis to evaluate the applied side of the research. The study included
the most important conclusions reached by the researchers, the most important of which
are: The low exchange rates have positive effects in encouraging exports and reducing
the volume of imports and creating an investment environment to attract new
investments while increasing the value of the currency, the volume of exports will
decrease with an increase in imports leading to dumping the market goods and goods
Importing and competing for local products especially if those products are of better
quality than local and at a lower price which reduces investment as well as the
withdrawal of investors from continuing especially in the agricultural sector. Therefore,
the researchers recommend: re-evaluation of local exchange rates and Floating by
leaving it to be determined on the basis of the mechanisms of the market in the light of
its purchasing power and not to exaggerate its role in encouraging exports and reduce
،imports and create a favorable investment environment.

The current study carried out in the Tigris River within two regions of Al-Sharqat (first
station) and Samarra (second station) / Salah Aldin from the period of December 2017 to
May 2018. The study include some biological aspects (length-weight relationships, condition
factor and food) for two freshwater fish species (Carasobarbus luteus and Planiliza abu).The
Differences in b value and condition factor were found between the two species within sex and
region. The food contents included seven types of food for C. luteus (plant parts seeds ,organic
material, diatoms ,crustaceans, insect parts , sand and clay grains and algae) and five for P. abu
(plant parts and seeds, organic materials, diatoms, sand and clay grains and algae) , The plants
parts and their seeds were the main food content and the percentage of food components varied
according to the species, stations, sex and months.

Comparative study has been carried out for some biological measurements (lengthweight relationship, condition factor, length-length relationship and food item types) for
two freshwater fishes, Himeri Carasobarbus luteus and Kishni Planiliza abu in Tigris
River within Tikrit region during the period from December 2017 to May 2018. Sixtythree C. luteus specimens were collected with total lengths ranged from 15.7-33.0 cm and
seventy-two C. aurata with total lengths ranged from 13.7-23.5 cm. The growth pattern
showed positive tendency, the weight and growth increased more than cubic length with
(b) values was 3.153 for C. luteus and 3.129 for P. abu , and the standard growth was equal to 3.084 for C. aurata males. Condition factor for C. luteus was (1.379) higher than P. abu
(1.215), While in C. luteus female showed relatively equal value to male, in addition in P.
abu female was higher than male. Fluctuation was found in condition factor with length
increasing in P. abu. The food components included seven types in C. luteus included
(plant particle's and seeds, organic matter, diatoms, crustaceans, insect parts, grains of sand
and clay and algae) and four types in P. abu (plant partials and seeds, organic matter, grains
of sand and clay, algae). Different plants parts and their seeds were the main food contents
flowed by organic materials, and percentage of food components varied according to fish
species.
The research cover, the ratios of twelve-morphometric measurements to total length, and
eight morphometric measurements to head length and their linear regression equations. The
length-length relationship between total length and others measurements were highly
correlated.

In this study, the factors affecting consumer preferences in milk and dairy products consumption in urban areas in the city of Mosul, Iraq were investigated. The data used for this purpose were obtained from the questionnaires from families with different income levels. Of the individuals examined, 29.59% were primary school graduates, 21.77% were high school and equivalent, 10.86% were college graduates, and 37.68% were university graduates with the increase in the income group, the proportion of individuals who graduated from university increases. According to the results of the study, 38.54% of the families consume open milk, 31.25% pasteurized milk, 11.46% milk powder and 9.38% sterilized milk. It was found that
223.96% freshness, 20.83% brand and 19.79% cheapness are the subjects that consumers pay the most attention when buying milk and milk products. When the consumption of milk and dairy products of domestic consumers is examined, 60.42% prefer imported products and 39.58% prefer local products. In the research area, the most common problems faced by consumers in the supply of dairy products are 41.66% being vulnerable, 29.32% being expensive, and 12.50% being hygiene. KMO analysis was conducted in the study of the factors affecting the preferences of the households examined in milk and milk products. T The scales affecting the consumers' purchasing decisions of milk and milk products (product origin (Factor I), product image (Factor II), product price (Factor III), sales method (Factor IV)) were determined as four factors.

This study was conducted to investigate chicken meat consumption levels and consumption behaviours of households in Mosul province, Iraq. For this purpose, face-to-face surveys were conducted with 96 homes in Mosul in July-August 2018, and similar studies were used in the analysis of the data obtained. The number of sample households was determined according to the "Non-Clustered Single Stage Simple Random Probability Sampling Based on Main Population Ratios" method. According to the results of the research; The average number of individuals was 4.74. It has been determined that 44.18% of the population is university graduates. The average
monthly income of the families was 1192395.83 dinars, the total expenditure was 591406.25 dinar, and the food expenditure was 272933.98 dinars. Per family in examined families average monthly consumption of chicken meat was 8.45 kg and 1.78 kg per person. It was determined that chicken meat consumption level varies in different income groups, and chicken meat consumption levels increased depending on the income level of consumers. Most of the families preferred to use chicken meat. When the frequency of chicken meat consumption of the families was examined, it was observed that 52.08% of the consumers consumed 2-3 times a week, 26.04 % once a week, 14.58% once every 15 days and 7.29 % once a month. On average, 62.50% of consumers buy chicken meat as whole chicken, while 37.50% report that they buy it in pieces. The most preferred part of chicken meat is breast meat with 59.38%, followed by thing thigh meat with 33.33% and wing meat with7.29%. It was determined that 72.92% of consumers consumed chicken meat at the same level in all seasons
