Opis:
Ensuring the homogeneity of the indoor climate throughout the greenhouse is very important for uniform plant cultivation. In the study carried out to determine the indoor climate distribution in the heated greenhouse in the terrestrial climate, indoor temperature, relative humidity, dew point and vapour pressure deficit values were measured from 8 different measurement points. The distribution pattern of the measurement points was made horizontally and vertically at 2, 4 and 6 meters. Sensor placements are grouped vertically at 2 meters (G1: S1, S2 S3), at 4 meters (G2: S4, S5, S6) and at 6 meters (G3: S7, S8). Measurements taken during the day are divided into three parts. The climatic changes in the greenhouse were monitored as daily (00:00-23:30), daytime (08:30-17:30) and night (18:00-08:00) hours. According to the results obtained from the research, it was determined that the indoor climate parameters in the greenhouse change during the average daily, daytime and night hours at different times of the day and at different locations. According to this, it has been determined that it is important for better regulation of the greenhouse climate by monitoring the changes in the plant level as it rises from the greenhouse floor to the ridge with multiple sensors instead of a single sensor.

Opis:
The goal of this study is to determine the crop water stress index (CWSI) and irrigation scheduling based on CWSI values, as well as to examine the correlations between CWSI, physiological parameters and grain yield of hybrid corn P31A34 in semi-arid climate conditions. In 2014 and 2015, the upper limit (UL) temperatures at which plants were entirely exposed to water stress were 1.178°C and 2.38°C, respectively. When the corn grain yield began to decline, the CWSI threshold value was 0.34, indicating the yield limit. Grain yield, crop water consumption, crop water stress index, chlorophyll content, water use efficiency and leaf area index were found to have negative correlations (p ≤ 0.01) with CWSI values in both years of the study. The findings revealed that in semi-arid climate conditions, a maximum of 30% water deficit could be used during the growing period of the corn compared to full irrigation (I100) for water savings and that a water deficit greater than 30% results in considerable grain yield losses. In areas with limited water resources, the moderate water deficit (I70) may be a viable alternative to the I100.

Opis:
With the increasing need for energy, energy studies to be obtained from waste gain importance. In this study, it has been tried to determine the amount of biogas energy that can be obtained from olive pomace (pirina), which is produced by processing oil olives. Numerical maps of pirina amounts and potential biogas energy values and location maps of the proposed pirina processing plant were created. The necessary calculations were made by comparing the obtained results with the relevant literature information. In the study, the current potential biogas energy amount was calculated, maps were created and the electricity and gasoline energy equivalent levels of this energy were tried to be calculated using the 2015-2019 data of the Mediterranean, Aegean and Marmara Regions. The total potential amount of pirina in the research area is 1853375.7 tons and the potential biogas energy amount that can be obtained is 33360762.4 MJ. Pirina, which is the production waste after pressing the olives for oil, can be used for energy production. By using pirina to obtain biogas energy, both the utilization of pirina and the development of the regions will be provided.

Opis:
This study was conducted to determine crop water stress index (CWSI) values and irrigation timing in the case of Derinkuyu dry bean (Phaseolus vulgaris L.). In 2017, dry beans were grown as the main crop according to the field design consisting of plots divided into randomised blocks. Irrigation treatment comprised full irrigation (I100) and irrigation issues with three different levels of water stress (I66, I33, I0). This study applied 602 mm of water under the I100 irrigation. The yield of Derinkuyu dry beans was equal to 3576.6 kg∙ha-1 in I100 irrigation. The lower limit (LL) value, which is not necessary for the determination of CWSI, was obtained as the canopy-air temperature difference (Tc - Ta) versus the air vapour pressure deficit (VPD). The upper limit (UL) value, at which the dry beans were wholly exposed to water stress, was obtained at a constant temperature. The threshold CWSI value at which the grain yield of dry beans started to decrease was determined as 0.33 from the measurements made with an infrared thermometer before irrigation in I66 irrigation treatment. As a result, it can be suggested that irrigation should be applied when the CWSI value is 0.33 in dry beans. Furthermore, the correlation analysis revealed a negative correlation between grain yield and crop water stress index and a positive correlation between yield and chlorophyll content. According to variance analysis, significant relationships were found between the analysed parameters at p ≤ 0.01 and p ≤ 0.05.
