This investigation studied the performance of 4 soybean genotypes (H30, H2F12, H117 and Giza 111) to three sowing dates (1<sup>st</sup> May, 20<sup>th</sup> May and 10<sup>th</sup> June) and also plant dense (105.000, 140.000 and 175.000 plant/fed.) during two summer seasons of 2013 and 2014. The effect of planting dates was important than other factors for flowering date, seeds weight/plant and seeds weight/fed. whereas, the effect of plant dense population was the most important for No. of branches/ plant and plant height. While, the effect of soybean genotypes was the most important for seeds oil percentage. The effect of planting date were more important than other factors for seeds yield (kg/fed.) the highest seeds yield/fed (2240 and 2126 kg) in the first and the second season respectively. Plant density showed high differences in seeds yield/fed. in which 175.000 plant fed. gave higher yield (2215.6 and 2108.6 kg/fed.)in the first and the second season respectively. Soybean genotypes showed high differences in seed yield/fed. in which H111 gave higher yield (2213.3 and 2124.1 kg/fed.) in the first and the second season, respectively, and surpassed all other genotypes. The seed oil and seeds yield/fed. Contents showed opposite magnitudes, planting in 20th May gave higher yield/fed with the lowest oil content (12.3 and 11.5%) in the first and the second season respectively. While planting in 10th June gave lowest yield/fed with higher oil content (18.3 and 16.1%) in the first and the second season respectively.

Field trials including two plant cane crops and one 1<sup>st</sup> ratoon were conducted in El-Mattana Agric. Res. Station, (latitude of 25.17° N and longitude of 32.33° E), Esna, Luxor Governorate, Egypt, during the two successive seasons of 2013/2014 and 2014/2015 to find out the performance of three sugar cane varieties (G.T. 54-9, G. 2003-47 and G.2003-49), which were planted using two planting densities (1.5 drills "37800 buds/fed" and 2 drills "50400 buds/fed") and fertilized with three nitrogen levels (180, 210 and 240 kg N/fed "fed = 0.42 ha-1"). A randomized complete block design (RCBD) using split-plot arrangement with three replications was used. The varieties were allocated in the main plots, mean while planting densities and nitrogen levels were randomly distributed in the sub–plot.
The important results could be summarized as follow:
Variety G.T.54-9 over passed the two promising varieties in length, diameter and fresh weight/plant of stalks. The two promising varieties (G.2003-47 and G.2003-49) over passed the commercial variety (G.T.54-9) in brix, purity and sugar recovery percentages and number of millable in the three crops. Variety G.2003-47 gave the highest sugar yield in the two crops and ratoon.
Planting density 37800 buds/fed attained a significant increase in stalk diametercompared with planting by 50400 buds/fed, meanwhile, the same planting density <em>i.e.</em> 37800 buds/fed produced the higher stalk fresh weight in the two plant cane crops and 1<sup>st</sup> ratoon. Planting density 50400 buds/fed attained the highest taller stalks, brix, purity and sugar recovery percentages, number of millable cane/fed and cane and sugar yields/fed, meanwhile, the same density reduced glucose % in the different crops.
Increasing nitrogen levels up to 240 kg N/fed led to significantly increased in stalk length, stalk diameter, stalk fresh weight/plant, number of millable cane/fed, cane yield/fed and sugar yield/fed for the three cane crops. Increased nitrogen levels from 180 to 210 and 240 kg N/fed caused significant increase sugar yield/fed in the three cane crops, this increment amounted by 15.67 and 23.24 % in the 1<sup>st</sup> planted cane, 13.83 and 18.81% in the 1<sup>st</sup> ratoon and 6.45 and 8.10 % in the 2<sup>nd</sup> planted cane, respectively.
The highest number of millable cane/fed was recorded when sugar cane planted with 50400 buds/fed and fertilized by 240 kg N/fed.
Variety G.T.54-9 attained the highest stalk fresh weight values with the different nitrogen levels over the two promising varieties. The best interaction was between variety G.2003-47 and 210 kg N/fed to produce the highest purity % in the three crops. The interaction between the varieties and nitrogen levels attained a significant influence on sugar recovery % in the 1<sup>st</sup> ratoon and the 2<sup>nd</sup> planted cane.
The 2<sup>nd</sup> order interaction between varieties, seeding rates and nitrogen levels recorded the highest cane yield/fed, however, this difference was not enough to reach the level of significant in the three crops.
It could be noted that from the economical view of growers’ benefit planting the promising sugar cane variety G.2003-47 is better, however the actual and the economical view growing the commercial variety with higher costs is better for the national economy where it will save about 2.49 ton/fed which represent a large amount of cane on the large area consequently a large amount of sugar production.

Assessment of Genetic Diversity in Bread Wheat Genotypes Based on Heat Tolerance and SSR Markers

EN
10.21608/ajas.2016.1987
Ten bread wheat genotypes (<em>Triticum</em> <em>aestivum</em> L.) were evaluated for heat tolerance under normal and late sowing dates during 2014/2015 and 2015/2016 seasons. Four agronomic traits, i.e. grain yield per plant (GYP), 1000-kernel weight (TKW), Spike length (SL) and plant height (PH) were evaluated. The genetic diversity was assessed among genotypes based on phenotypic data and thirteen simple sequence repeats (SSR) markers, representatives of nine wheat chromosomes. Heat stress under the late sowing date was quite strong resulting in 30.4, 14.6, 14.7 and 28.8% average reduction for GYP, TKW, SL and PH, respectively. GYP showed a negative and significant correlation (<em>r</em>= -0.66, <em>P</em><0.05) with heat susceptibility index (HSI) under heat stress. By using 13 SSR markers, a total of 125 DNA fragments were generated, with an average of 9.6 bands per marker. The level of polymorphism (%P) ranged from 25% for the marker Xgwm497-1A to 85.7% for Xwmc273-7A, with an average of 60.8%. The highest polymorphism information content (PIC) value (0.36) was also recorded for Xwmc273-7A, while the lowest PIC (0.11) was found with Xwmc398-6A, with an average of 0.23. A highly significant correlation (<em>r</em>= 0.872, <em>P</em><0.01) was found between %P and PIC values. Cluster analysis based on phenotypic data classified the ten genotypes into two groups, of which the group-1 genotypes (Line-1, Line-2 and Line-3) showed high tolerance to heat stress by exhibiting lowest HSI values. However, cluster analysis based on SSR markers generated two clusters, where cluster-I contained five genotypes (Line-1, Line-2, Line-3, Debeira and EL-Nilein) tolerant to heat stress, indicating the efficiency of SSR markers in discriminating wheat genotypes. Moreover, four SSRs generated some unique bands or specific for some tolerant genotypes, that could be used as markers associated with heat tolerance in wheat. However, additional markers analysis is still required to validate their usefulness in breading programs.

10.21608/ajas.2016.1995
Divergent phenotypic selection was performed for flag leaf angle (FLAN) under heat stress in five F<sub>2</sub> populations of bread wheat (<em>Triticum</em> <em>aestivum</em> L.). Direct responses for FLAN and correlated responses for grain yield per plant (GYP) and thousand kernel weight (TKW) were measured. FLAN was positively and significantly correlated with GYP and TKW under heat stress. Positive and highly significant (<em>P</em><0.01) responses to selection for FLAN were obtained in both directions for the five populations, which were higher in magnitude in the low direction (averaged 31.41) than those obtained in the high direction (averaged 22.0%). Selection for high FLAN produced concurrent positive and significant (<em>P</em><0.05) responses in GYP in only two populations, with an average of 5.17%, which was lower in magnitude than averaged correlated responses (8.24%) obtained in GYP for lower FLAN in four populations. Significant (<em>P</em><0.05) correlated responses to selection in TKW for higher FLAN were obtained in four populations (averaged 4.03%) and were smaller in magnitude than those obtained for lower FLAN (averaged 9.56%). Additive gene effects were found to be mainly controlling FLAN. Moderate realized heritability estimates obtained for FLAN (averaged 0.53) were similar to heritability obtained by parent-offspring regression (averaged 0.50). Bulked segregant analysis (BSA) using twelve simple sequence repeats (SSR) markers for FLAN identified three SSR markers, namely Xgwm294-2A; Xbarc113-6A and Xwmc398-6B were able to distinguish high from low bulks in at least two populations. Three bands specific for high and two specific for low FLAN were generated, that could be used in the future as markers associated with FLAN under heat stress in wheat. The information presented here could help in understanding the genetic system controlling FLAN and its relationship with grain yield under heat stress.

10.21608/ajas.2016.1999
RAPD-PCR was performed using six random primers to identify the genetic diversity among six plant samples belong to two genera (<em>Euphorbia</em> and <em>Ricinus</em>). The dendrogram, based on genetic distance, depict the relationship among the investigated plant samples, separate clearly the six samples. The closest relationship was observed between <em>E. geniculata</em> and <em>E. aphylla</em>; and <em>E. pulcherrima</em> and <em>E. peplus</em>, while this relationship was quite separated between these four samples and the other two samples <em>E. cactus</em> and <em>R. communis</em>. Fragments generated by the six primers show a polymorphism ratio of 88.9%. Bands 3500 and 750 bp generated by primer OP-Z13, and also bands 2000, 1500, 1400, 1200, 1000, 720 and 550 bp generated by primer OP-A09 existing only in the plant samples of <em>E. geniculata</em> and <em>E. aphylla</em>, which suggest that these bands can be used as a positive molecular marker to identify these plant samples. Bands 2500, 1720, 1650, 1300, 950 and 250 bp generated by primer OP-A09, and band 1200 bp generated by primer OP-A20 and band 350 bp generated by primer OP-Z19 and band 250 bp generated by primer OP-Z17 were common in all plant samples of family <em>Euphorbiaceae</em>. Moreover, band 430 bp generated by primer OP-Z17 was characterized for <em>Ricinus communis</em> and absent in other plants of genus <em>Euphorbia</em>. Also, band 2700 bp generated by primer OP-A20 and band 210 bp generated by primer OP-Z19 existing only in <em>Euphorbia peplus</em>. This study highlights the usefulness of RAPD assay for determining genetic variation in different plant genera and for estimating genetic distances between different plant samples. Moreover, knowledge of genetic distance among genera and species, and genetic diversity/structure within genera could be useful for conservation of genetic resources. Data presented here are the first report in Egypt of genetic variation inside genera <em>Euphorbia</em> and <em>Ricinus</em> described at the molecular level. We consider this work as a first step in molecular characterization of genera <em>Euphorbia</em> and <em>Ricinus</em>, thus, it is recommended to extend the panel of samples and primers in the future. <em> </em>

10.21608/ajas.2016.2025
This study was carried out to investigate the possibility of making molded bread of quinoa and wheat flour blends. Wheat flour replaced and mixed with 5, 10, 20 and 30% of quinoa flour. Physiochemical characteristics and properties of these blends and bread making were evaluated and analyzed. The chemical composition of quinoa and wheat flours and their blends were determined via evaluation of protein, fat, moisture, ash and fiber contents. In addition, mineral elements (Iron, zinc, calcium and phosphorus), percent of wet and dry gluten, and falling number of quinoa and wheat flours were determined. Also, Farinogram parameters were studied to investigate some rheological properties of blends dough.
Obtained results showed positive relationship between content values of ash, protein, fat and fiber, and the percentage of quinoa flour. Higher values of mineral elements were recorded as the percent of quinoa flour increased, except zinc which was non-significant in all samples. Increasing amounts of quinoa flour lessened and reduced strong and extensible dough, whereas, wet and dry gluten, development time and stability of dough decreased as the percentages of quinoa flour increased.
Molded bread was prepared using straight dough method in order to evaluated bread specific volume and sensory characteristics. The results showed fewer differences in bread specific volume, between samples prepared from wheat flour or those with 5 and 10% quinoa flour blends. Results showed that blends with 5 or 10% of quinoa flour had good properties to make molded bread and had satisfactory and acceptable organoleptic evaluation.

10.21608/ajas.2016.2052
This study was conducted out to improve the quality and the shelf-life of Saidy date variety during storage period for 12 months at room temperature using packing under vacuum, drying and irradiation (1KGy) treatments. Results showed that packing under vacuum is more effective for controlling the insect infestation (3.85%) followed by the irradiated (11.12%), dried (12.11%). While, the control sample recorded 17.24%, at the end of storage time (12 months). The moisture content of the control date sample decreased from 15.23 to 9.29% at the end of storage while it was decreased from 15.23 to 9.67%, from 15.15 to 8.92% and from 15.80 to 9.67% for the packed under vacuum, dried and irradiated samples, respectively. Data showed that, during the storage periods (12-months), the protein contents reduced from 2.52 to 1.97%, from 2.52 to 2.02%, from 2.57 to 2.15% and from 2.45 to 2.09% for the control, packed under vacuum, dried and irradiated samples, respectively. Data revealed that total bacterial counts immediately decreased after irradiation and drying to a greater extent, compared to the reduction in molds and yeasts. Beside, the microbial flora in all treatments remained at low count until the end of storage period. The irradiated sample had the lowest microbial counts, followed by the packed under vacuum and dried samples. The organoleptic evaluations show that the panelist could not discriminate between the non-irradiated and irradiated date fruits. Furthermore, all treatments have no detectable adverse effect on the preference rating of the fruits. The irradiated samples were occupied the first rank in overall acceptability of sensory evaluation followed by the dried and packed under vacuum samples. These results suggest that packing under vacuum, drying and irradiation treatments of Saidy date fruit could be used as alternative methods for improving the fruit quality, as well as prolonging its marketable period at room temperature for 12 months or more.

EN
10.21608/ajas.2016.2060
The effects of GA<strong><sub>3</sub></strong> and CPPU on fruiting of Seewy date palm grown at the Experimental Orchard, Faculty of Agriculture, Assiut University, Egypt were investigated during 2013, 2014 and 2015 seasons.
All treatments were sprayed after two or eight weeks of pollination. The experiment was set up in a complete randomized block design with five replications of one bunch each.
The obtained results could be summarized as follow:
- Fruit set and fruit retention percentage were significantly decreased due to spray GA<strong><sub>3</sub></strong> at 50 ppm after two weeks of pollination followed by GA<strong><sub>3</sub></strong> or CPPU after eight weeks of pollination compared to unsprayed one (control).
- Spraying the bunch with GA<strong><sub>3</sub></strong> twice, once at 50 ppm after two weeks of pollination followed once GA<strong><sub>3</sub></strong> at 75 ppm plus CPPU at 7.5 or 15 ppm after eight weeks of pollination gave the highest fruit weight, flesh percentage and dimention of fruits compared to unsprayed ones.
- Spraying GA<strong><sub>3</sub></strong> and CPPU significantly improved the chemical fruit properties in terms of the total soluble solids and sugar contents and significantly decreased the total acidity and total soluble tannins percentages compared to unsprayed ones.
So, it concluded that spray GA<strong><sub>3</sub></strong> at 50 ppm after two weeks of pollination plus either GA<strong><sub>3</sub></strong> at 75 ppm and CPPU at 7.5 ppm or GA<strong><sub>3</sub></strong> at 75 ppm and CPPU at 15 ppm to obtain the high yield with good quality of Seewy dates. GA<strong><sub>3</sub></strong> reduce the fruit retention and consequently increase the fruit weight and size induce increased the yield. CPPU induced an increase in fruit weight and size then get high yield of Seewy dates. Thus, spraying the bunches of Seewy date palm with GA<strong><sub>3</sub></strong> and CPPU had get the heaviest yield with improvement the physical and tested chemical fruit properties.

10.21608/ajas.2016.2065
This study was conducted during two successive seasons 2014 & 2015 to investigate the effect of coating and wrapping materials on storability and quality of Balady mandarin fruits during the storage period. Fruits were coated with salicylic acid, paraffin oil or camphor oil, as well as wrapped with foil paper and untreated. The fruits were stored either at room temperature or cold conditions (0±2°C) + humidity of 90±5%.
The results showed that the fruit weight loss %, fruit decay %, total soluble solids % and TSS/acid ratio were significantly increased with prolonging the storage period. On the other hand, the advanced storage period induced a gradual decrease of fruit juice percentage acidity %, vitamin C and total phenolic contents levels.
All treatments caused decreased fruit weight loss and fruit decay percentage under both storage conditions. Using foil paper wrapping or salicylic acid gave the least fruit weight loss and decayed fruit percentage, respectively. The most loss reduction was associated with the cold storage than room temperature conditions. Also, all treatments improved the fruit quality during the storage period compared to the untreated ones.
So, it could be concluded that oil coating or wrapping maintained fruit freshness without negative effects on fruit quality parameters. Meanwhile, coating and wrapping fruits retained high levels of juice volume, acidity, ascorbic acid (V. C) and total phenolic contents as well as lower total soluble solids and TSS/acid ratio loss than controls during storage. Such treatments can be used as alternative of chemical application in order to maintain human health and environment.

Shoot tip explants (0.5 cm) of four citrus rootstocks (trifoliate orange, sour orange, volkamariana and lime) were cultured on MS medium including vitamins supplemented with100 mg/l myo-inositol and 2.5 g/l gelrite. Three types of sugars (sucrose, fructose, glucose)were used at different concentrations (88, 132 and 176 mM) and two types of amino acids were used astryptophan at 0, 50, 75 and100 µM and glutathione at 0, 5, 10 and 20 µM. Growth regulators were used during multiplication and rooting stages as follow: a) multiplication,BAP at 1.0 mg/l and b) rooting, IBA at 0.5 mg/l. Sucrose was most effective on shoot and internode length and roots/shoot butthe number of shoots/explant, number of nodes and rooting percentage were more pronounced on the medium containing glucose, while fructose was more effective on the root length. Concerning amino acids, generally tryptophan was more effective on vegetative and rooting growth compared to glutathione.

This study was carried out through 2014 and 2015 in a private date palm orchard located in New Assuit City district, Assuit Governorate to study the effect of spraying with different concentrations of two seaweed extraction, (Eprosil-k at 4%) and (Oligo-x at 2 or 4%) either alone or with silicon nutrient at (0.5%), on yield and fruit quality of Zaghloul date palms. palms sprayed three times during grown seasons (first of April, May and June) with Seaweed extracts at 2 or 4% either alone or with silicon were very effective on improving yield and fruit quality (fruit weight, dimensions, total soluble solids and sugar contents) in comparison with control treatment. The promotion on these characters was observed when the concentrations of Oligo-x (Seaweed extract compound) were increased from 2 to 4%. The best results with regard to yield and fruit quality of Zaghloul date palms were obtained due to spray the palms three times with a mixture of seaweed extract (Oligo-x at 4%) and silicon nutrient at 0.5%.

This experiment aimed to investigate the effect of the different irrigation water sources and spraying with seaweeds on the seedlings of two plants one is salt-sensitive (<em>Citrus sinensis</em>) and the other is salt-tolerant (<em>Ziziphus mauritiana</em>) through studying growth parameters, as well as biochemical attributes and minerals in leaves of the studied plants. Four treatments were used for irrigation water as follow: (W1)The Tap Water (control) E.c = 1.2 dS.m<sup>-1</sup>, (W2) Shatt al-Arab river (sub river) Ec = 5.2 dS.m<sup>-1</sup>, (W3) Shatt al-arab river (main) 6.2 dS.m<sup>-1</sup>, (W4) The well water E.c = 8.1 dS.m<sup>-1 </sup>with 3 levels (A1, A2, A3) of seaweed treatments prepared from (Agrosign marine) in the concentration of (0, 2, 4 ml /L), The results explained that there is a decrease in all parameters in this study with increasing the salinity of irrigation water and this is represented in well water irrigation as compared with another water types, while the interaction withseaweeds treatments caused significant increases in the growth parameters, biochemical attributes and minerals contents. This promotion was associated with increasing the concentrations to (4 ml /L), Which gave 42.94 cm in plant height, 2.00 number of shoots, 24.61 in the number of leaves, 5.34 in stem diameter, 101.2 g in fresh weight and 19.02 g dry weight. On the other hand the interaction with seaweed extract increased significantly growth parameters, attributes biochemical and mineral content, it gave the highest value A3W1 which was 3.48 mg /g in the total chlorophyll and 73.82 mg/g in total carbohydrates, while the lowest at A1W4 which was 1.38 mg/g in the total chlorophyll and 42.92 mg / g in the total carbohydrates. The activities of the enzymes superoxide dismutase (SOD), peroxidase (POD) and catalase (CAT) have shown a marked increase when increasing the level of salinity in irrigation water as well as, the seaweeds extraction caused increasing in the content of these enzymes. The treatment (A1W4) gave the highest enzymes activities CAT, SOD, BOD which was 24.10, 21.83 and 7.93 u / g / f.w respectively.

10.21608/ajas.2016.2100
The current study area is part of Wadi El- Assiuty, Assiut, Egypt. It is one of the most promising developed areas in Egypt. It lies in the eastern desert of Assiut city. It is located between longitudes 31°18' and 31°48' E and latitudes 27°10' and 27°45' N. The study aims to generating a semi-detailed soil map that is suitable to achieve a land capability evaluation of Wadi El- Assiuty soils using "ILWIS"-GIS.
Visual interpretation was first undertaken on an enhanced natural color composite landsat TM image and overlaid on Digital Elevation Model (DEM) for the preparing of geo-pedological soil map using the 3D GIS capabilities. The mapping units of the study area were strictly verified in the field where19 soil profiles were selected to represent the different mapping units. The soil profiles were carefully described and representative the soil samples were taken from each profile. Then, the main physical and chemical characteristics of the different mapping units were determined and stored into "ILWIS"-GIS database. The soils were classified up to the sub group level according to the protocol of the United States Department of Agriculture (USDA Soil Taxonomy, 2014a). The main soil sub groups that were investigated in the study area were; Typic Haplocalcids and Typic Haplosalids.
California Storie index, (Storie, 1978) and O'Geen <em>etal.</em> (2008) are used to rate the soil capability for intensive irrigated agriculture. The results were displayed as maps using "ILWIS"-GIS.
Results indicated that the area currently lacks the high capability class. However, three soil capability classes of C2, C3 and C4 were recognized in the study area. About 32493.60 feddans (29.9% of the evaluated soils) are moderately capable, 73387.14 feddans (67.3%) are marginally capable and 3156.26 feddans (2.9%) indicating limited capability. A potential capability map was also produced after eliminating the correctable limitations, by improving the soil properties some of these soils can approach potential capability. The results show that 67.3% of the total study area is potentially suitable for agriculture.
From this study, it is recommended to improve the current capability of the studied soils by applying soil management practices that include:
- Adding organic and chemical fertilizers to improve moisture availability, nutrient availability and CEC.
- Executing a leaching process for removing the excess of soluble salts.
- Using modern irrigation systems to reduce the irrigation periods to avoid salts accumulation and the formation of soil crust in the calcareous soils.

Investments of the key tools for economic and social development is through increased production, and increase the capacity of the national economy to face global challenges as well as creating new job opportunities contribute to raising the standard of living, which turned out to be the economic sector's ability alone without the agriculture sector on advancing economic development matter which requires attention to the agricultural sector and increase the size of investments against him.
The.refore,.the study.concluded.the.following:
Low investments directed to the agriculture sector size as it's not proven significant statistical model of the value of total agricultural investment at current prices during the study period, and agricultural investment for the public sector at current prices the value of an annual fall drop significant statistically, while the moral model did not prove the statistical value of agricultural investment to the private sector prices ongoing during the study period, the national-level investment sectors of industry, petroleum, electricity and.construction.value. increases.annually.confirmed statisticall.ysignificant.increase.
Increase the relative importance of the contribution of private agricultural investment to total investment directed to the agriculture sector size, it could be limited to the most important factors affecting the agricultural investment in several factors, the most important agricultural income value, the value of agricultural exports, the value of agricultural imports, national exports, the value of national imports, the value of loans agricultural, the value of agricultural savings, interest rates, crop area, planting area, the area under cultivation, as sure a statistically significant sample paced factors affecting agricultural investment, and about 95.1% of the changes in agricultural investment total, but due to the national income, and that the change in national income. 10% leads to a total change.of.agricultural.investment.by.41.7%.
The growth rate of the agricultural sector arising from the General Agricultural investment and private agricultural investment in Egypt totaled 0.02, which means that to increase the growth rate in the agriculture sector by 1% it has to be to increase domestic investment to the agriculture sector rate of 0.02%.

The most important findings and recommendations
This search is talking about not keep up with domestic production of wheat crop and high increase in the national consumption of it the size and appearance of a gap between domestic production and national consumption and widening the gap year after year and that the state was forced to import increasing quantities of wheat and flour to fill this deficit
This research aims to define the economic importance of foreign trade as well as identify key import wheat crop sources and identify current geographical distribution of imports of wheat in order to re-geographical distribution to reduce the value of these imports.
The results showed that the total trade value of the value of total exports and total imports followed a growing trend became a time of agricultural exports and imports value increased as well and that the United States Australia and France are key countries and stable sources for the supply of wheat to Egypt.
The results proved that the re-distribution of wheat imports geographically for the first alternative, and on leaving the imported wheat quantities to be distributed freely to various countries as the least expensive and we found that the quantities imported spread over three countries, namely Canada, Turkey, Kazakhstan and the second alternative regards to quit imported quantities of wheat free distribution within each group by country Lowest price and in accordance with the export of energy for these countries, and we found that the quantities imported were distributed to Canada, France, Turkey, Kazakhstan, and the third alternative regard to restricting the model to import 50% of the total amount of the France and the distribution of the rest of the quantities imported in accordance with the state of the least expensive and depending on the energy export for each country, and the rest of the quantities distributed between Turkey and Kazakhstan. Alternative fourth regard to restricting the importation model of the countries where the price per ton of no more than 2110 pounds, and in accordance with export capacity of each country. And distributed quantities imported in three countries, namely Canada, Turkey and Kazakhstan.
<strong>According to the results of the study we recommend the following</strong><strong>:</strong>
1- Reduce import of wheat flour imported a pill to take advantage of milling residues in animal feed, poultry and prevent the use of wheat in animal and poultry food.
2- Increase the total exports in general and agriculture in particular, and the targeting of high-price markets to raise export earnings and increase the coverage rate and raise the efficiency of foreign trade.
3- The use of the purchase method of long-term contracts directly with distinct states in wheat production and a stable import and be in the dates of the emergence of the crop as it is the best chance for the contract to the low price.
