IRAQI JOURNAL OF DESERT STUDIES, 2021, Volume 11, Issue 1, Pages 1-10

This study aimed to evaluate The number of pure inbred lines of maize (Zea mays L.) carried out for two seasons (spring and autumn) of 2019 in the fields of the research station/ agricultural research station in Abo Gharib. Four cytoplasmic male sterile inbred lines (A1, A3, A5 and A7) with their maintenance lines and four genetically fertile inbreds ( Inb2, HZ3, R5 and 18) in addition to the control hybrid (Nahrain) were used. Single hybrids were produced according to line × tester system. All genotypes were planted using randomized complete block design (RCBD) in three replicates, to analyses general and specific combining ability and estimate the effects and estimation some genetic Parameters for number days of sowing to 50%, leaf area, rows number per ear, kernels number per row , 500-kernel weight and grain yield per plant. Comparison results showed that inbred lines and their single crosses presented significant differences for all studied traits. The hybrids (A1×HZ3), (A1×R5) and (A3×HZ3) scored highest yield (175.1, 172.2 and 172.1) respectively. Obtained results also recorded significant influence of GCA and SCA in most studied traits, And the values of GCA/SCA was less than one, And the percentage of broad sense heritability was high for all traits, while it was low for the narrow sense heritability for all traits as well, which led to a higher average degree of dominance than the correct one, which indicates that the traits were under the influence of the dominance and over dominance of genes, which indicates that the possibility of using superior parents in their speculations to derive Single hybrids with special combinability of field characteristics, yield and components.

IRAQI JOURNAL OF DESERT STUDIES, 2021, Volume 11, Issue 1, Pages 11-28

This study was carried out at an olive farm located in Habbaniyah, 30 km east of Ramadi, the center of Anbar province in Iraq during the 2020 growing season to study the effect of foliar spraying with boric acid with three concentration levels 0, 0.5 and 1.0 g L-1 and seaweed extract under the trade name Alga600 with four concentration 0, 1.0, 1.5 and 2.0 g L-1 and their interaction in some of the vegetative and chemical characteristics of the olive c.v "Chemlali". The trees were sprayed till run-off on three dates. The first spray in the beginning of March before flowering and fruit set, the second spray after 1 month from the first spray after flowering and before the fruit set and the third spray after 2 month from the first spray after flowering and fruit set. The results showed the positive effect of foliar spraying with boric acid on all the vegetative growth characteristics of the olives, where the concentration 1.0 g L-1 significantly exceeded the rate of increase in branch length, number of leaves, total chlorophyll, dry matter ratio, carbohydrates, nitrogen, C/N and boron in the leaves compared with the control treatment (distilled water), spraying with seaweed extract at a concentration 2.0 g L-1 significantly outperformed most of the traits compared to the comparison treatment , while the interaction treatment (1 g L-1 Boric Acid + 2 g L-1 seaweed extract) was superior in the rate of increase of branch length and total chlorophyll, the percentage of leaves dry weight, total carbohydrates, leaves content of nitrogen and boron, compared to the comparison treatment, (1.0 g L-1 Boric Acid + 1.0 g L-1 seaweed extract) was significantly superior in the number of leaves compared to the treatment (0.5 g L-1 Boric acid + 1.0 g L-1 seaweed extract), which gave the lowest value in the number of leaves in olives.

Abdul Hameed W. A. B. Al-Issawi

IRAQI JOURNAL OF DESERT STUDIES, 2021, Volume 11, Issue 1, Pages 42-67

The research included that there are large areas whose spatial advantages can be invested in agricultural activity through the spatial suitability of the two elements (water and soil) by following scientific methods and modern technologies that are compatible with the nature of desert environment, in a way that contributes to achieving development, stability and achieving justice. Research is based on modeling (12) randomly selected samples of water and soil which their locations were determined by using (GPS) and examined laboratory. Their results revealed that there is a clear variation in the spatial characteristics according to the nature of the area. The theory of spatial modeling was applied to it by adopting (G.I.S. and remote sensing techniques R.C.) and producing cartographic models that represent the suitability for the characteristics of each element, and the merging of the characteristics in two models representing (water and soil) to reach a final model in which the area was divided into regions (poor, medium, Convenient, and very convenient), according to the advantages of each one.

Kawthar N. Abbas

IRAQI JOURNAL OF DESERT STUDIES, 2021, Volume 11, Issue 1, Pages 93-115

The effect of water requirements in the cultivation and production of some vegetable crops (summer and winter) was studied in order to determine the importance of water during the different stages of growth in order to carry out the vital processes, as most of the physiological processes within plants in general are affected directly or indirectly by the presence of water, the research took Abu Ghraib district as a model for the study, as it is one of the important districts that are famous for cultivating vegetable crops that feed the markets of Baghdad , and the research has reached To the fact that moderate soil moisture is important in the germination of crops, as its decrease negatively affects the failure to germination, the failure to elongate peacocks, or the production of incomplete fruits. As for the increase of that moisture, it causes great damage to the vegetable crops, such as their exposure to diseases and pests, as is the case with air humidity, as its decrease leads to Drought and falling branches and leaves, as well as its effect on the increase in the process of evaporation - transpiration, which leads to the withering of crops. As for its height, it leads to the disruption of the pollination process. It was also found that some vegetable crops are well cultivated in high air humidity, such as lettuce, spinach and leafy greens, and that some of them are well cultivated in low humidity. Such as watermelon and watermelon, and it was found that the decrease or high of the fallen rain or irrigation water negatively affected the growth and germination of vegetable crops.

Ayad A. M. Alheeti; Nihad M. Abood; Rashid M. Theer

IRAQI JOURNAL OF DESERT STUDIES, 2021, Volume 11, Issue 1, Pages 116-131

Iraq faces major environmental challenges because of its geographical location in the arid and semi aired areas that of desertification sensitivity and the global climate changes, especially in its central and southern parts as in the Al Anbar governorate. According to the UN reports, %92 of Iraq's area is in one way or another exposed to desertification as represented by dust storms, dune movement, deterioration of natural vegetationو droughts, and waterlogging and salinization of the soil. The desertification areas in Al Anbar estimates by %77 of the total area of 137,808 km2 of the governorate. Global attention in combating desertification has involved the implementation of preventive measures to halt and reduce desertification. The most effective way to combat desertification has been found through the introduction of agricultural systems that ensure the conservation of agricultural, natural resources (soil and water) and goes in line with the emerging environmental changes. This article presents the justifications for proposing a conservative agriculture system as an ideal solution to combat desertification in the Al Anbar governorate. The results of the research on the applications of conservation agriculture indicate that the conservation agriculture application leads to reduce soil erosion, mitigate droughts and scarcity of water resources, increase water usage efficiency, and increase productivity and economic return. These findings urge investing in the advantages of the conservation agriculture system to combat the desertification phenomena in the Al Anbar governorate. What should be emphasized in this context, however, is the need to double efforts and provide official support from the relevant authorities.

Bashar A. Mahmood

IRAQI JOURNAL OF DESERT STUDIES, 2021, Volume 11, Issue 1, Pages 150-163

Euphrates River is the primary source of water in Anbar province. It provides the cities that passed with drinking, agricultural and industrial water, in addition to being the downstream of sewage and wastewater after treatment. Anbar province, and consequently the water of the Euphrates River, has been affected by climate and environmental changes resulting from the military operations, which have become an obsession for citizens and decision-makers in the province. This obsession became the motivation for conducting the necessary physical, chemical and biological measurements to identify the environmental characteristics of the Euphrates river due to the presence of many sources of pollution of rivers water and for the purpose of making sure that it is suitable for human uses, since its effects will be serious and direct on humans and the environment. The review article includes a comprehensive study of water quality in Anbar province, as well as a review of previous researches in this field to know and to improve the future of water in the province. As the specialists unanimously agreed that, the future crisis in the region is a water crisis. Also, the review included an analysis of physical, chemical, and biological measurements, and a comparison of results with Iraqi and international standard limits was made. Data were organized and the results were analyzed. Results were of importance, and important environmental recommendations were reached regarding Euphrates river within its flow stream and the time effect on it.

NATURAL REASONS CAUSING SOIL SALINITY AND ITS IMPACT OF PLANT PRODUCTION IN ALI-ALGHARBI DISTRICT

Kahdem A. H. Al-Jassim

IRAQI JOURNAL OF DESERT STUDIES, 2021, Volume 11, Issue 1, Pages 164-186

Salinity is one of the major problems of Iraqi agriculture, especially in central and southern Iraq, including the study area (Ali Al-Gharbi district) in Missan province, as this problem is considered one of the problems impeding agricultural production, as most agricultural lands are subject to different degrees of salinity due to Natural and human conditions such as the prevailing climatic conditions represented by high temperatures and evaporation, the Topography and the vegetation and the salinity of irrigation water in addition to the lack of effective drainage and drainage networks and high levels of ground water and poor management of soil and water and other reasons that lead to soil salinity. The effect of soil salts on plants begins with the accumulation of a large amount of salts in the soil. Boring it becomes difficult for plants to absorb water, and these salts must be kept away from the plant roots ( Rhizosphere ) in the region by adding more water during the washing process, which reduces their forgetting in the soil and the soil becomes effective for agricultural production. The quality of irrigation water is also an important factor that helps to salinize the agricultural soil, as this water contains different quantities and types of salts, it is natural that part of it will be left on the agricultural land due to the continuous use of it, especially in irrigated agricultural areas and under the conditions of dry climate and semi Dry, when the amount of salts added to the soil through irrigation water exceeds the amount of salts removed by natural or artificial puncture and by crops being harvested, this leads to the accumulation of salts in the soil in the future.

IRAQI JOURNAL OF DESERT STUDIES, 2016, Volume 6, Issue 1, Pages 104-114

Nowadays, there is an urgent necessity for the expanding in the green areas existed inside the cities to its role for improving the local climate and increasing its efficiency. So it lead to identify the concept of the thermal comfort and the determinants elements. Private climate was assessed according to thermal comfort requirements and investigated how it is suitable to the people who lived in the city and to show the role of these green areas for improving the local climate and increasing its efficiency. That determinants were indicated and discussed precisely. From most important results, It could be concluded that research derived:
1- The green areas can be considered as an element that motivated to balance the ecosystem inside city environmentally, healthily, beautifully, from its effect on temperature sun radiation and its control on wind speed, humidity%, in addition to its role on lessening the pollution and noise .
2- Reduced strategical importance and not realizing the importance of these green areas inside the city and the weave dealing with the social, environmental and climate elements which lead to prevent the city and its people from advantages of green areas. Thus, it could be recommended that green areas have to be increased inside city and protect them from wrongdoers. Furthermore, this study could be as trigger to treat dust storm in Iraq.

Study was conducted in the western desert (south east of Al-Ramadi city) to shed light on drought tolerance,
twelve of a number of already establishment field of Phoenix dactilyfera L. ( Zahde) trees which are used in this
study. Through out the best 8 years half of the trees was being irrigated regularly while the other half irrigation
was stopped two years period to the start of the experiment and contained to the end of it. Measurements on the
leaf water potential and water loss were taken during the day hours (from dawn to sunset) for several days.
Seasonal diurnal changes in total carbohydrates and other phenotypic characteristics, N and K percentage were
recorded. Dunces Multiple Range was used to separate the means at 0.5% probabilities. Changes in water
potential values, water loss, total carbohydrates, N and K percentage depended largely on irrigation vs. nonirrigation
and seasons, beside the nutrient elements were in low level in summer specially in leaflets of nonirrigation
date palms

IRAQI JOURNAL OF DESERT STUDIES, 2013, Volume 5, Issue 1, Pages 57-70

The Ceramic industry is one of the constructional industries that contribute to the development of the
construction sector. The quick scan of the Iraqi market shows that there are large quantities of ceramic products
of different types and specifications of different measurements. It shows too that the demand continues to
increase, particularly in recent years due to the reconstruction and the high level of per capita income. Iraq is one
of the oldest manufacturers of ceramic products, but that the Iraqi state did not pay attention to the industry
though a large proportion of the raw materials needed for production are available locally in very large quantities
and better qualities of the world as well as the availability of skilled manpower in this field. It is worth
mentioning that the Anbar province has three plants (Sanitary ware, Wall Tiles, Floor Tiles) for the production of
ceramic materials founded before the occupation. These plants, owned by the General Company for Glass and
Ceramics in Ramadi, are the only plants in Iraq and they stopped production since 2003. It is concluded that
Iraqis full ofmany of themineralsand raw materials, which are concentratedmostly inAnbar provinceand
representthe basicbackboneofthe ceramic industryin the province. But the results ofestimatingdemand show that
there isa cleardeficitin the production ofceramicmaterialsto meetthe threetypes ofincreasing demand for
thesematerials.Thedomestic demand forsanitary wareandWalls andFloors Tiles for the year 2013was (16,357)
tons (11,546,160) m 2(15,394,880) m 2, respectively, which meansthat theproduction capacitiesavailable forthe
threeplantscover only(27.5%) (10.5%), (6.5%). While in theyear 2023, the percentage of the production ofthe
threelaboratoriesofdomestic demandis(sanitary ware, 9.21%), (Tiles walls, 8.4%) and (Tiles floors, 5.2%). So,
the study is encouraging for the rehabilitation ofthe production ofceramicprojectsin the province ofAnbar, as
well asthe establishment ofnew projects that have the potentialto bridge theshortfallin the demand forthisproduct.
The results ofthe application of value criteria show that the three projects are economically useful, but the Wall
Tiles project is more useful than the other two projects. In addition, the three projects are not substitutes for they
are all urgently needed, but in case of the failure of funding the rehabilitation of all the plants, so it is preferable
to start with the Wall Tiles plant.
