    Opis:
    Nowadays the increasing number of animal enterprising depending on the needs of human population growth and nutrition need that was occurred during the production of animal breeding have revealed the manure issue. Manure from animal barn, when not stored properly, causes environmental problems including odour and visual pollution, and could create environmental pollution problems. On the other hand, random storage of manure on the land outside animal barn as a result of climate parameters such as rainfall results in leakage of manure and can cause contamination of water resources. In Turkey, animal manure obtained from animal barns is almost not utilized and is accumulated outside. Manure which is produced in animal barn to be used for agricultural purposes must be stored in the areas which prevent the spread of in the environment . Thus, the loss of minerals in the soil plant available forms are contained in manure, will be prevented. In addition, due to the nutrients and microorganisms, surface and underground water resources can be a factor in polluting and may create a risk to animal health and environmental pollution. The study has been carried out by determining the 4950 cattle breeding enterprises around the Eğirdir, Beyşehir Burdur and Salda lakes in the Lakes Region. About 50000 cattle are bred in the 4950 cattle breeding enterprises in the study area. However, of these animals 43502 are bred for commercial purposes. When the values in literature are taken into account, the daily manure amount that would be put forth has been calculated as 1500 tons. It has been concluded that animal manure which is the output of animal breeding enterprises will result in environmental pollution, water resource pollution as well as posing a threat to life in general by mixing with water resources such as underground water, lakes etc. when deposited haphazardly in stacks that are not well managed. As a result, we believe that our producers should be well informed regarding manure management prior to experiencing such problems.

    Opis:
    The aim of soil solarization is to control soil borne pathogens and weeds heating with solar energy of soil which is sufficiently wetted. Soil water content is the one of the most important factors affecting soil solarization. Humidity level is important to convey temperature from the upper layers to down layers of soil in solarized soil. For this purpose, the study was conducted in plastic greenhouse in Isparta province. Beginning of the study, all plots were irrigated to reach the field capacity, and then the all plots were irrigated in 5 days irrigation interval during the experiment periods. Temperature distribution was measured in 5, 10, 20 and 30 cm of the soil profile along the experiment periods. As a result of this study, increasing of soil temperature and effectiveness of solarization decreased with together the water content of soil in upper layers. However, the soil temperature increased with irrigation in the down layers.

    Opis:
    Biological nitrogen fixation (BNF) is the process that provides organic nitrogenous compounds to the plants by using molecular nitrogen in atmosphere. Higher plants are not capable to use molecular nitrogen in atmosphere as a nitrogen source to generate essential proteins. Therefore plants either should be fertilized by adequate nitrogenous fertilizers or the microorganisms which are capable to produce nitrogenase should provide nitrogen to the plants by BNF. From among a number of factors affecting BNF, soil moisture content and ambient temperatures are considerably effective on the fixation rate. Therefore the global warming would be dramatically defective on BNF, thus effects of soil moisture as well as soil and ambient temperatures on BNF should evaluate prior rising temperature. A pot experiment was carried out to determine the effects of soil water contents on BNF. Four different soil water contents (%25, %50, %75 and %100 of water holding capacity) were adjusted either every 3 days or just after plants indicate wilting point. Non-inoculated pots were added to experiment as a control. The results revealed that BNF is affected by different level of soil water content. The mechanism of this effect would not be the direct effect of water, but the side effect of water on soil oxygen content; therefore, an aeration capability.

    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.

    Opis:
    Based on the amount and duration of external temperature, degree day values are determined according to whether the selected equilibrium temperature is lower or higher than the air temperature. Degree day values are calculated according to the fluctuations in ambient temperature. It can be understood whether heating or cooling systems are necessary within the calculated periods. In this study, the meteorological data of Antalya region dating back many years and the temperature values suggested according to the cultivation periods of tomato in greenhouse environment have been used as material. The daily average temperature values recorded for many years have been compared with the equilibrium temperature values selected for the tomato plant thereby calculating the heating and cooling day values for each cultivation period. Tomato cultivation in greenhouses is carried out in 2 periods in the region in spring and autumn. At the end of these two periods, it was determined that the heating degree days in autumn were determined to be higher than that in spring. Whereas cooling degree days were determined to be greater for autumn cultivation in comparison with that of spring cultivation. Information regarding the energy consumption of an agricultural structure can be obtained beforehand via the heating and cooling degree day values. It has been surmised that such studies will help in making estimations regarding the energy need of various agricultural structures as well as gaining insight in the planning of the design stages that are directly related to the energy consumption of the building such as heating, cooling and ventilation.

    Opis:
    An ideal broiler house should be designed to minimize the effects of weather changes and to keep indoor conditions at the comfort temperature of the animals. In this case, this should be done with minimum cost and possible lowest operating costs. Degree-day methods are used in order to have knowledge of the energy need of any structure. With this method, the measured values or meteorological data can be used to give information about the heating and cooling energy quantities of structures. Depending on the climate change in recent years, the changes need to be examined that have taken place in order to provide optimum comfort in animal barn. Isparta province and districts were selected as the study area. The longterm average daily temperature values are used from meteorological stations of the selected region. The heating and cooling degree day values were calculated for selected balance temperatures in broiler breeding. Linear Regression Analysis and Spearman Rank Correlation Test were conducted to determine the changes of these values due to climate change. In conclusion, it was determined that there were statistically significant trends at 5% significance level in Egirdir (21°C), Isparta (31-29-25 and 23°C), Kasimlar (18°C), Senirkent (31-29-25-23 and 21°C), Sutculer (all selected balance temperature values) and Yalvac (31-29-25-23 and 21°C) in terms of heating degree-day values, and in Atabey (29-25-23-21 and 18°C), Barla (25-23 and 21°C), Isparta (23-21 and 18°C), Senirkent (29- 25-23-21 and 18°C), Sutculer (29-25-23-21 and 18°C), Sarkikaraagac (25-23-21 and 18°C), Uluborlu (25-23-21 and 18°C) and Yalvac (25-23-21 and 18°C) in terms of cooling degree-day values. As a result, it has been concluded that more energy consumption will be a concern for heating and cooling of the broiler house that will be built in the province of Isparta.

    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.
