Fragmented land prevents irrigation system efficiency to reach the desired level. In arid and semi-arid zones land consolidation offers opportunities for increased irrigation system efficiency.The objective of our study was to determine factors for adoption of irrigation system as related to land consolidation. The Logit regression model was used to analyse survey data. Villages on the Bursa-Karacabey Plain of Turkey, where land consolidation and irrigation system were planned, were used as study sites. Results show that supplying sufficient water in canals, ease of irrigation planning, reducing in water losses, ease of maintaining the irrigation and drainage system, and labour requirement significantly affected the adoption of irrigation systems.Publication An analysis of dairy cattle production in southern marmara in terms of heat stress(Namik Kemal Üniversitesi, 2016-01-01) Yaşlıoğlu, Erkan; İlhan, Hüseyin; YASLIOĞLU, ERKAN; İlhan, Hüseyin; Ziraat Fakültesi; Biyosistem Mühendisliği Bölümü; 0000-0002-3865-7863; 0000-0002-9080-4082; ABE-6643-2020; F-9264-2017High outdoor-temperatures in summer months lead to the increase in indoor temperature. High indoor-temperatures with high humidity, resulting heat stress in dairy cattle. Nowadays, temperature humidity index, improved based on air temperature and relative humidity relationship, is a commonly used method for determining the effect of heat stress in dairy cattle. Under the heat stress conditions, feed intake and thus milk yield of dairy cattle is reduced.Southern Marmara is a very important region for dairy cattle production. Heat stress analysis was performed for Balikesir, Bursa, and Canakkale, in which high milk production and large dairy cattle farms are existed. For analysis, temperature humidity index were calculated for each city. Meteorological data from 2007 to 2014 for each city were obtained from Turkish State Meteorological Service. Temperature humidity indexes for each city were calculated based on hourly average temperatures and relative humidity. On condition that no measure is taken to reduce the effects of heat stress, reductions in the milk yield of dairy cattles resulting from heat stress were evaluated separately for each city and the daily total milk losses were also analyzed.According to analysis results; daily milk losses per cow in Balikesir, Bursa, and Canakkale were 0.05 kg, 1.02 kg, and 0.78 kg in June; 0.42 kg, 2.48 kg, and 2.68 kg in July, and 0.30 kg, 2.70 kg, and 3.07 kg in August, respectively. Higher milk losses in June were observed in Bursa, Canakkale, and Balikesir, respectively. Also in July and August, higher milk losses were observed in Canakkale, Bursa, and Balikesir, respectively.Publication The effect of building orientation on utilization of solar energy in dairy cattle barns(Namık Kemal Üniversitesi, 2021-09-01) Delice, Hatice; Yaslıoğlu, Erkan; DELİCE, HATİCE; YASLIOĞLU, ERKAN; Fen Bilimleri Enstitüsü; Biyosistem Mühendisliği Bölümü; 0000-0002-3865-7863; 0000-0002-0781-2154; ABE-6643-2020; ERM-4916-2022In Turkey and the World, energy demand is continuously increased. In addition to the rapid depletion of fossil fuel resources used to supply the energy needs, ambient temperatures is risen, glaciers are melt and natural disasters are occured in our planet. In addition, people, animals and plants are greatly damaged due to the adverse effects of soil, water and air pollution. Solar energy is renewable, clean and easily accessible energy. Our country is more advantageous in terms of solar energy potential in comparison to many other countries and benefitting from this potential is very important. With the increasing importance of renewable energy sources, photovoltaic (PV) panels, which are able to convert solar energy directly into electrical energy, are not polluting the environment and easy to implement, are become more common. The inclination angle and position of the photovoltaic panels are the parameters that directly affect the production of electrical energy. Electrical energy is extensively used in agricultural production activities, as in every field. Especially, in animal production systems, the cost of electrical energy is an important input due to the high mechanization and the use of automation. This study was carried out in the dairy cattle barn with a capacity of 50 head in Bursa province. It was aimed to determine the amount of electrical energy produced by photovoltaic (PV) panels, located on the barn roof in four different directions (North-South, East-West, Northeast-Southwest, Northwest-Southeast), and also to find out whether produced energy is sufficient or not to meet the energy requirement of the barn. The electrical energy produced by the panels to be placed on the roofs was determined by using PVSOL software. According to the results, the amount of electrical energy produced from the panels with North-South (N), East-West (E), Northeast-Southwest (NE) and Northwest-Southeast (NW) orientation was determined as 179.453,0 kWh, 159.655,0 kWh, 175.950,0 kWh and 138.245,0 kWh, respectively. The annual electrical energy requirement of the barn with 50 head capacity was calculated as 25.200,0 kWh. In this case, it was calculated that the energy produced from the N, E, NE and NW orientations met the requirements of the barn by 5 to 7 times.Publication Air quality measurements in four sheep barns part ii: Pollutant gas emissions(Springer, 2021-01-04) Kılıç, İlker; Şimşek, Ercan; Yaşlıoğlu, Erkan; Heber, Albert; Uğuz, Seyit; KILIÇ, İLKER; ŞİMŞEK, ERCAN; YASLIOĞLU, ERKAN; UĞUZ, SEYİT; 0000-0002-3865-7863; 0000-0002-3994-8099; 0000-0003-0087-6718; ABH-7275-2020; AAH-3553-2021; AAG-8511-2021; ABE-6643-2020Pollutant gas emissions from animal barns affect indoor air quality, the health and well-being of farmers, and the surrounding environment. This study was carried out in four sheep barns (SB) in Bursa, an important region for animal husbandry operations. Concentrations of NH3, CO2, H2S, and CH4 were measured in four sheep barns by monitoring throughout 24 h in 1 year. Pollutant gas emissions from barns were also calculated and modeled. The average pollutant gas emissions obtained in this study were 5 kg day(-1) barn(-1) for NH3, and 18 kg day(-1) barn(-1) for CH4. The average NH3 and CH4 emissions from each barn were 2.1 and 2.7 kg day(-1) barn(-1) for SB1; 9.4 and 12.9 kg day(-1) barn(-1) for SB2; 4.0 and 3.6 kg day(-1) barn(-1) for SB3; and 4.5 21 kg day(-1) barn(-1) for SB4, respectively. There are statistically significant differences between daytime and nighttime for pollutant gas emissions. Pollutant gas emissions in the monitored barns are generally higher in summer than in other seasons. Models for estimating NH3, and CH4 emissions were developed using measured temperature and relative humidity values in the barns. These models can only be used in the Bursa region. The results of this study were compared with other studies under similar conditions in the literature.Publication Ammonia and carbon dioxide concentrations in a sheep barn(Kahramanmaras Sutcu Imam Univ, 2017-01-01) YASLIOĞLU, ERKAN; ŞİMŞEK, ERCAN; KILIÇ, İLKER; Onuk, Apti; Ziraat Fakültesi; Biyosistem Mühendisliği Bölümü; 0000-0002-3865-7863; AAH-3553-2021; ABE-6643-2020; AAG-8511-2021Indoor air quality in animal barns directly affect to animal productivity. Measuring the pollutants in animal barns proves the negative effects of gases on health of animals and workers. Most studies in this context focused on some pollutant gases such as ammonia, carbon dioxide, methane and hydrogen sulfide in dairy barn and poultry houses. Less attention in studies in scientific literature was paid to sheep barns which may have more important portion than other animals for the animal production sector of some countries. This paper revealed the concentrations of ammonia (NH3) and carbon dioxide (CO2) in naturally ventilated sheep barn in Bursa region, western Turkey. Also indoor environmental conditions such as temperature and relative humidity were measured simultaneously with pollutant gas concentrations. Regression and variance analyzes were applied to assess data collected in sheep barn whole over the study period. The average NH3 concentration during the study was 15 ppm for exhaust and 0.77 ppm for ambient, CO2 concentration was 1022 ppm for exhaust and 457 ppm for ambient. There was significant difference among measurement days for exhaust NH3 and CO2 concentrations (P< 0.001). The lowest NH3 concentration was 8 ppm while lowest CO2 concentration was 277 ppm, and the highest concentrations were 38 ppm for NH3 and 1700 ppm for CO2. Also minimum, maximum, average values for indoor temperature were 16.06 degrees C, 26.53 degrees C, 20.69 degrees C, respectively, while minimum 43.42%, maximum 89.6%, average 71.23% values for relative humidity were obtained. According to regression analyze results, the exhaust NH3 concentration related statistically significant with air velocity. The standardized coefficients suggest that indoor temperature and relative humidity sustained the greater effects on CO2 concentrations (P< 0.001).
