Water and nutrients are the main physiological requirements of human beings and therefore vegetal nutrients are of great importance to humans. In order to obtain the required plant diversity under the conditions of variable climate, soil and topography, it is necessary to ensure that the amount of water required by the plant during the growing season is stored in the root zone of the plant, which is called "irrigation". Global warming and population growth factors increase the need for water, which necessitates the most efficient use of existing water resources. The use of stored stormwater for irrigation purpose is one of the main solution methods of irrigation water supply and these storage facilities are made with high cost. The maximum agricultural benefit can be achieved by optimizing the cropping patterns that determine the weighted average of the plant water needs of the irrigation area. In this study, to determine the cropping pattern two different objective functions are used. Those functions are the maximization of irrigation area and the maximization of agricultural profit. The first objective function results in a linear programming problem whereas the second one is a nonlinear programming problem. The solution is obtained by using Microsoft Excel – Solver program using Simplex and GRG methods for two objective functions, respectively. The developed formulation is applied to Çimendere-1, Çimendere-2, Gözsüz, Karaevli, Hüsünlü and Kılavuzlu Ponds in Tekirdağ.

Agricultural production is one of the most basic requirements of humanity to survive and water is vital for it. Therefore, human beings have been working on water resources giving the necessary importance throughout the history. Problems like irregularities in streams regime, droughts and climate change force to use water more efficiently. In addition, population growth has increased the demand for agricultural water. Nowadays, with the construction of dams for irrigation purposes, these demands can be met ...
Temporal and spatial changes in the abundance and biomass of pico (heterotrophic bacteria & synechococcus) and nanoplankton (flagellates) of the Mersin Bay – relationships with ambient physical, chemical and biological parameters
Gazihan Akoğlu, Ayşe; Uysal, Zahit; Department of Marine Biology and Fisheries (2011)
The eastern Mediterranean has been known as the most oligotrophic water body among the worlds oceans and as a result of limited nutrient inputs from terrestrial sources primary productivity and plankton succession are restricted by lack of nutrients especially by phosphorus and nitrogen. Within this domain, Mersin bay forms a so called hot spot (highly sensitive) area where a sharp contrast exists between the coastal area supplied by land-based nutrient sources and the nutrient limited open sea. Excess nutr...
Investigation of in-vitro digestive behavior of beef and poultry which are tenderized by enzymatic and acidic marination
Baştürk, Bilge; Öztop, Halil Mecit; Özvural, Emin Burçin; Department of Food Engineering (2021-9-09)
Meat contains valuable nutrients, exceptionally high-quality proteins that include all essential amino acids and vitamins and minerals for the human diet. Meat is mostly tenderized to make it more tasteful and palatable. The effects of tenderization on the physical, chemical, and microbiological changes in meat have been investigated in many studies. In this study, acetic acid, citric acid, lactic acid solutions, and a commercial meat tenderization solution were used to tenderize the red and white meat (bee...
Evaluation of the water-food nexus with the focus on agricultural water management in the Upper Sakarya watershed
Özel, Beyza; Alp, Emre; Department of Environmental Engineering (2021-5-15)
This study investigates the tradeoffs between water and food (agriculture) nexus and evaluates alternative scenarios focusing on sustainable water governance for agricultural production in Upper Sakarya Basin. For this purpose, pressures on surface water and groundwater resources are determined for the study period (2004-2016) by considering inputs and outputs such as demand, supply, and discharge by all sectors. With concentrating on the impacts on demand and supply dynamics, the effectiveness of managemen...
Understanding the biotechnological potential of bifunctional enzyme: catalase-phenol oxidase

Catalases are common enzymes in all aerobic and many anaerobic organisms. Their main function is the decomposition of hydrogen peroxide into oxygen and water. Four classes of catalases have been defined including monofunctional heme-containing catalases, catalase–peroxidases, manganese catalases, and minor catalases. Although they have been studied for many years, a secondary peroxide-independent oxidative function of catalase is regarded as a new term discovery in the literature. Catalase–phenol oxidase (C...
