The Impact Of Elevated Co2, Uv-B Irradiation, And Rising Temperature On Quinoa, Mohamed Yousif

Theses

Climate change is driving simultaneous increases in atmospheric CO₂, surface UV-B radiation, and temperature, yet most crop research has examined these stressors in isolation, leaving their combined effect on nutritional quality poorly understood. Quinoa (Chenopodium Quinoa Wild.), a stress-tolerant C3 pseudocereal, has been promoted as a climate-resilient forage and food crop for arid regions, but its performance under realistic multi-stress conditions remains uncertain. This study therefore asked whether quinoa can maintain biomass, yield, and mineral quality when exposed to elevated CO₂, enhanced UV-B, and rising temperature individually and in combination, and whether their interaction is additive or non-additive.

Evaluation Of Field Grown Grapevine Grafts For Drought Tolerance Under Water Deficit Irrigation In The Arid Regions Of Uae, Sonu Krishankumar

Thesis/ Dissertation Defenses

Grapevines, among the most commercially significant fruit crops, are valued for their use in table grapes, raisins, and winemaking but are highly vulnerable to abiotic stresses such as drought, heat, and salinity. This study investigated the morphological, physiological, biochemical, and transcriptomic responses of grafted grapevines to drought stress, emphasizing rootstock-scion interactions. Grafting experiments were conducted with three rootstocks (Ramsey, RU140, and Paulsen) and table grape varieties (Thomson Seedless, Crimson Seedless, and Flame Seedless), with five combinations as Flame seedless × Ramsey (V1), Thompson seedless × Ramsey (V2), Crimson seedless × R110 (V3), Crimson seedless × Ramsey (V4) and Thompson seedless …

Biochemical Characterization Of Date Palm (Phoniex Dactylifera L) Seeds Maintained At Microgravity In Outer Space Iss, Shamma Khalid Aldhaheri

Theses

The UAE’s vision to reach space dates to 1976 when Sheikh Zayed Bin Sultan Al Nahyan met with the National Aeronautics and Space Administration (NASA) Apollo group; this meeting marked the first attempt of UAE to enter the field of space science. The UAE is currently one of the top countries executing space missions and research. This research focuses on the biochemical characterization of date palm seeds that are sent to the International Space Station (ISS) in outer space. The research methodology involves biochemical analysis of seeds maintained under two different environmental conditions-microgravity and standard gravity. In total, 30–45 seeds …

Comparison Of Three Different Woody Plant Species For Their Ability To Utilize Nutritional Elements Supplied In The Form Of Biosolids And Mineral Fertilizers, Fatima El-Telib Hassan

Theses

Crop production systems of the future will need to focus on recycling rather than flow- through of mineral nutrients. Much of the nutrients that leave agricultural systems with crop products eventually end up in household waste and sewage. Returning nutrientrich products from wastewater treatment to agricultural soils must be done in an environmentally sound and culturally acceptable manner. More than 300,000 hectares of forest have been planted in the United Arab Emirates (UAE), consisting mainly of native species, such as Prosopis cineraria (Ghāf) and Vachellia tortilis (Samr). It has been proposed that sewage sludge, the dry residue from wastewater treatment, …

Ranking The Counties In Ease Azarbaijan-Iran Based On Agriculture Development Criteria Using Copras Model, Razieh Pourdarbani, Asghar Pashazadeh

Emirates Journal for Engineering Research

Understanding inequality and imbalances within different geographical areas (country, province and city), and policymaking to reduce inequalities are among the key tasks of the administrators in geographical development sector. Therefore, it is necessary to identify level of development and underdevelopment of agricultural areas in order to achieve sustainable agricultural development. A list of 36 indices including 10 agronomic indices, 7 horticultural indices, 8 livestock indices and 11 mechanization indices was prepared using Statistical Yearbook of 2016. The agricultural ranking of 21 counties was made using the Copras model. Also counties clustered using cluster analysis method included in SPSS software and …

Design, Fabrication And Evaluation A New Mechanism To Automatic Weight Transfer Control System On A Tractor, Javad Tarighi, Seyed Saeid Mohtasebi

Emirates Journal for Engineering Research

Increasing tractor weight during agricultural operations is one of ways to optimization the performance of tractor tires interacting with soil. One of these methods is adding weight on the front of the tractor, which leads to better engagement of front tires with soil. In four-wheel drive tractors also causes better steering wheel drive tractors, in addition it prevents from weight transfer to the rear of the tractor, which causes overturning. In this research, a new approach has been proposed that proves automatic weight transfer is possible by putting some lightweight instead of main weights on the front of the tractor. …

Cost Estimation Of Wastage Irrigation Water In Arid Public Landscape Areas King Abdullah Park– Dammam, Saudi Arabia, Ali Al-Sulbi

Emirates Journal for Engineering Research

The Kingdom of Saudi Arabia (KSA) locates within the territory of tropical deserts where water is one of the most important natural resources. However considerable amount of water has been wasted, on daily bases, in irrigation of public landscaped areas managed by local municipalities. Water wastage related to issues include improper calculation or no calculation of plants water budget; malfunctionality or failure of irrigation system components, tools and equipment; misunderstanding of soil-water and plant relationships; and improper management of irrigation operations. This research aims to estimate the cost of wasted water in association with irrigation of public landscape areas in …

Agroclimatic Zoning For Cultivation Of Saffron Using Ahp Approach In Sarab, Navid Yaghoubzadeh, Razieh Pourdarbani, Ardavan Ghorbani, Gholamhossein Shahgholi

Emirates Journal for Engineering Research

According to agricultural experts, saffron is one of the crops that can be a good solution to the problem of drought in a water crisis situation. A plant which uses low water consumption and high economic incomes is a good alternative to wheat, a water-consuming crop. Saffron does not need water at all in the summer, and in the fall and winter, rain will irrigate this crop and require very little water during the year. This study was conducted to select the optimum location of saffron cultivation and its comparative study in Sarab with regard to the role of important …

Date Palm Wastes As Growth Substrate In Hydroponics To Grow Lettuce (Lactuca Sativa L.), Khawla Mohammed Al Marzooqi

Aridland Agriculture Theses

Recently, many countries are practicing a variety of modern farming techniques like hydroponics, aquaponics, aeroponics vertical farming etc., to enhance production and quality of the production. Among such techniques, hydroponic system of production is growing plants in an appropriate substrate, which provides both physical and nutrient support with a suitable root environment. Substrate media can be either inorganic or organic. In this study, date palm leaf waste has been used, rock wool slab and cocopeat slab. The main objective of this study is to investigate the feasibility of using palm leaf wastes as a growing substrate extensively in the hydroponics …
