Impact Of Saline Water Irrigation On Date Palm (Phoenix Dactylifera) Associated Bulk Soil Bacterial Communities In Oases Agroecosystem Of Uae, Fardous Abdi Ibrahim Jibar Alhashmi
Impact Of Saline Water Irrigation On Date Palm (Phoenix Dactylifera) Associated Bulk Soil Bacterial Communities In Oases Agroecosystem Of Uae, Fardous Abdi Ibrahim Jibar Alhashmi
Theses
Irrigation of date palm (Phoenix dactylifera) with saline groundwater is routinely practiced in the arid agroecosystems of United Arab Emirates (UAE), due to freshwater scarcity. Saline groundwater irrigation is known to deposit salts in the top layers of soil and increase soil salinization. However, how increasing soil salinization affects the belowground bacterial communities, is not well investigated. Soil samples were collected from 14 different date farms where irrigation water source was either non–saline water or saline groundwater. Soil bacterial communities were identified using 16S rRNA gene metabarcoding. The results showed that bacterial diversity (including Shannon diversity, richness, and …
Yield, Nutrient Contents And Antioxidant Levels In Basil (Ocimum Basilicum L.) Grown In Aquaponic And Soil Systems, Maryam Ahmed Albedwawi
Yield, Nutrient Contents And Antioxidant Levels In Basil (Ocimum Basilicum L.) Grown In Aquaponic And Soil Systems, Maryam Ahmed Albedwawi
Theses
A study was conducted to evaluate the performance of Ocimum basilicum L. in both aquaponic and soil systems in the UAE climatic condition. The experiments were conducted under greenhouse conditions. Plants were raised in aquaponic beds with ornamental fishes in different concentrations. At the same time, a set of plants were raised in pots under a greenhouse set-up. The studied parameters were morphological (total weight and leaf number, shoot and root length, number of branches), biochemical (chlorophyll a, chlorophyll b, total chlorophyll, anthocyanin, xanthophyll, protein, and phenol contents) and antioxidant levels (Ascorbic acid and tocopherol). For analyzing the stress effects …
Effect Of Natural Elicitors And Cold Storageperiod On Quality Improvement Of Uae Date Palm Fruit (Phoenix Dactylifera L. Cv. Khesab), Shamsa Salem Nasser Abdulla Alblooshi
Effect Of Natural Elicitors And Cold Storageperiod On Quality Improvement Of Uae Date Palm Fruit (Phoenix Dactylifera L. Cv. Khesab), Shamsa Salem Nasser Abdulla Alblooshi
Theses
Date palm (Phoenix dactylifera L.) is one of the most important fruit trees grown in arid and semi-arid regions. Despite the immense capabilities of date palm, it is still a challenge to maintain fruit quality, marketability, and shelf life. The objective of this study was to investigate the synergistic effect of a preharvest spray application of the natural elicitor chitosan (Ch) 1% alone and in combination with salicylic acid (SA) 2 mM and calcium chloride (Ca) 3%; (Ch, SA, Ca, Ch+Ca, Ch+ SA, Ch+ SA +Ca) on the quality parameters, shelf life and bioactive compound content of date fruit of …
Mineral Nutritional Status Of Plants Of A Public Park Under Long-Term Irrigation With Treated Sewage Effluent, Chandana Chakraborty
Mineral Nutritional Status Of Plants Of A Public Park Under Long-Term Irrigation With Treated Sewage Effluent, Chandana Chakraborty
Theses
Treated sewage water is widely used for irrigation of urban greenery in UAE, and it contains significant number of elements that serve as nutrients for plants. The crucial unresolved question that remains, is regarding its long-term impact on the nutritional status of plants. Sulaimi Park of Al Ain was chosen as the study site. The main objective was to examine if the nutrient supply was adequate for plants. N, P, K levels were expected to exceed plant demands and micronutrient supply was assumed to be below plant requirements. To assess this, soil pH, annual nutrients input with water and elemental …
Optimising The Carcass Merit Of Irish Beef Cattle Using Genetic And Non-Genetic Information At The Animal And Herd Level, David Kenny
Theses
Failure of beef carcasses to achieve desirable carcass specifications represent inefficiencies within the supply chain, namely greater carcass processing costs and the inability of the resulting primal cuts to conform to high-value market specifications. Analysis of a representative sample of prime Irish beef cattle conducted in this thesis determined that 59% of cattle fail to achieve the desired carcass specifications of the supply chain at slaughter. The objective of this thesis was to use readily available information to define strategies that could help to reduce this statistic. Firstly, the likelihood of Irish beef carcasses achieving the desired carcass specifications was …
