Opis:
Information on the energy needs of agricultural production activities carried out in any region can be obtained in advance. Many methods are used for this purpose. One of them is a degree-hour method. Kumluca district of Antalya province where pepper cultivation is done intensively was chosen as a study area. The growers prefer autumn production of pepper plants inside the greenhouses in this region. Production starts in early October and last until June. The long-term (1960-2015) thermometer temperatures in the study area were obtained from the Turkish State Meteorological Service. In this study, by using only meteorological data, during each growing season (planting, flowering, pollination, fruit ripening and harvesting) were obtained degree-hour values for the pepper plant and evaluated with Student-t test. Regression coefficients were obtained by correlating heating and cooling degree-hour values with different temperature values which are recommended during the vegetative growing season for the pepper plant. Regression analysis was performed between obtaining heating and cooling degree-hour values (dependent variable) and annual mean heating and cooling degree hour values (independent variable) which are suggested basic temperature values. In conclusion, the regression coefficients were determined as 0.99 for out of greenhouse heating degree-hour and as 0.90-0.99 for cooling degree-hour, respectively. Heating and cooling-hour values were found between 0.96-0.88 and 0.99-0.87, respectively. It was determined that there are very high correlations in the positive direction. According to different growing seasons of pepper, knowing how much less or more of heating and cooling degree-hour values is needed, one can give information in advance in terms of energy consumption or usage. Areas or regions where less energy is to be used can be determined in terms of agricultural production to be done in any region.

Opis:
Degree-day values can be calculated using climatic data. Thus, seasonal, monthly, daily and hourly energy requirements for heating and cooling in buildings can be calculated. The effect of outside ambient temperature can be determined by means of the degree-day method in determining the basic temperature values in buildings. The altitude and latitude affect significantly the temperature distribution in the Earth. Thus, the latitude and altitude values are required to determine the degree hour values. This study was taken in 9 provinces located in the Southeastern Anatolia Region (SAR). The annual outdoor dry-bulb thermometer temperatures for a long period of nine provinces in the SAR were obtained to determine heating and cooling degree hour values according to the six different base temperatures. According to the suggested six different base temperature values, the cumulative long-term annual heating degree-hour (HDH) value was 50862 in total for Gaziantep province. The lowest cumulative long-term annual heating degree-hour value took place in Sanliurfa province as 39638. Also, the highest total cooling degree-hour (CDH) value took place in Sanliurfa province as 10886 degree-hour value and the lowest value took place in Sirnak province as 3909. It was determined that there was not an exact linear or monotonous relationship between HDH and CDH values and altitude, latitude and longitude values. However, although it was seen that the relationship of CDH values with the altitude was not a formal linear or monotonous relationship, it was determined that CDH values decreased linearly together with the increasing altitude values when the values were examined.
