Özet:

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.
