Modeling of Growth Degree-Day Values of Tomato (Solanum lycopersicum L.) Plant: The Case of Çukurova Region
Keywords:Tomato, Modelling, Çukurova, Temperature and Rainfall, GDD
AbstractIn this study, tomato plant, which is among the most grown vegetables in our country, was chosen as the subject of the research. In the production of tomato, Çukurova region has an increasing production potential in recent years. Therefore, Çukurova region was chosen as the study area. In this study, the long-term temperature and rainfall values of the provinces in the research area constituted the material of the study. Growing Degree-Day (GDD) method was used in the study. The base temperatures were selected for the developmental stages of the tomato plant. GDD values were calculated according to the base temperature values of tomato plant in the developmental periods. The calculated values were examined and the suitability of the provinces in the research area was determined. In line with this information, it was concluded that the province of Mersin stands out. Predetermination of crop production areas and production according to these areas will affect the yield positively. Therefore, the increase of the producer's income will also contribute to the national economy in a positive way. In addition, multiple nonlinear regression equations were developed according to the basic temperature values selected for the growth stages of tomato plant. As a result, by using these equations, it was concluded that the variables that affect GDD values of tomato plant will be informed about the development of tomato in advance.
