A beef cattle barn has an important effect on the beef cattle production. The animal shelters which are planned and built suitable to the environmental conditotions increase the yield each animal, in addition to other factors such as feeding, husbandry and breeding, for this reason, the existing animal shelters in different regions of our country have to be studied and the appropriate shelter plans should be prepared. The purpose of this study is to investigate the existing structural conditions and environmental conditions (temperature, relative humidity, ventilation, lighting) to explore the possibilites for the improvement of present structures and to design the suggestible plans for the beef cattle bam in Tokat province. For this purpose 105 beef cattle bams were selected in this region.

Researchers have turned to alternative studies in order to benefit more from renewable energy sources due to fossil resources will be insufficient in the near future, environmental pollution as a result of fuel combustion and increasing energy demand. Biogas production, which is used in many areas such as heating, transportation, electricity, natural gas and chemical production, is one of the most attractive alternatives among these studies. Animal manure is also an important material used as a substrate in the production of biogas. For this purpose, the province of Van, which is one of the leading provinces of our country in terms of animal production and where cattle, sheep and poultry are grown intensively, was chosen as the research area. In the research, TUIK (Turkish Statistical Institute) 2021 data were used. It was made evaluations on the animal numbers data of the province of Van for 2021 and the amount of total manure and the biogas potential were determined. As a result o...

Rational use of soil and water resources is an obligation to increase the agricultural production. Thus, soil and water resources have to be both qualitatively and quantitatively assessed, and these resources have to be improved in order to solve the present problems. Although irrigated land is increasing very rapidly each year in Tokat province, available water resources are not used properly and irrigation is not applied consciously. In order to provide sound agricultural development, necessary investments on water resources development programs need to be done. This study is important in providing necessary data base for the future studies which will focus on solution of problems regarding on soil and water resources.

In this research, the most suitable growing period for greenhouse warm season species was defined based on long term meteorological data. Considering the climate requirements of warm season species, air conditioning periods such as heating, natural ventilation and cooling periods were determined for nine locations in Tokat. In addition, the climate requirements for Tokat were compared to Antalya in which greenhouse production was done very intensively. Winter growing greenhouse production in Tokat requires very high heating and lighting costs. But in summer months control of greenhouse indoor temperature in Tokat has advantages compared to Antalya. As a result of this study, it is suggested that in addition to early autumn production, late spring and summer production should also be encouraged in Tokat.

A rational use of land and water resources is essential in attaining agricultural production growth. This calls for studies to determine the existing soil and water resources in quantity and quality and improve these resources for solving problems. Although there is an increase in the total size of land cleared for irrigated agriculture each year in the Middle Black Sea Region, where significant problems prevail in terms of land and water resources, the existing water resources in the region cannot be benefited satisfactorily and a desired irrigation has not been achieved so far. For the development of the agricultural aspects of the region, necessary investments to develop water resources should be implemented. The socio-economic structure of the region could be improved through implementing sustainable projects regarding land and water resources primarily. Investigating and reviewing studies conducted on land and water resources of the Middle Black Sea Region, the problems encount...

Discharge of untreated waste waters into surface waters creates significant pollution in these resources. Wastewaters are most of the time discharged into seas, rivers and other water bodies without any treatments due to high treatment costs both in Turkey and throughout the world. Constructed wetlands, also called as natural treatment systems, are used as an alternative treatment system to conventional high-cost treatment systems because of their low construction, operation and maintenance costs, energy demands, easy operation and low sludge generation. Today, constructed wetland systems are largely used to treat domestic wastewaters, agricultural wastewaters, industrial wastewater and runoff waters and ultimately to prevent water pollution and to improve water quality of receiving water bodies. In present study, currently implemented practices in design, construction, operation and maintenance of constructed wetlands were assessed and potential mistakes made in different phases th...

Storage is one of the most important elements that provide the consumption continuation throughout the year for various products. Nevşehir, the center of Cappadocia, is the candidate for being 8th wonder of the world, presents visual feast to World Tourism by its marvelous geography and its natural formations. Most of us don’t know there is another side of this geography and nature secret underground. The biggest natural underground stores of the world which someone seen doesn't believe in his eyes and someone seen can never imagine take place in Cappadocia. Unlike the modern storage facilities in the world, underground storage facilities have been built in the layers of volcanic tufa in the Cappadocia region to store potato, apple, citrus and onion. These storages do not require any cooling equipment and use only the cooling impact of natural tufa. There is no need for heating and cooling in these storages, thus the investment costs are quite lower than the conventional storage...

In Turkey, agricultural lands are mostly composed of small, fragmented and scattered plots. Size of agricultural lands usually decreased through inheritance, then productivity of these lands decreased in time. As the number of plots increases, the area to be allocated for plot boundaries, roads, agricultural roads and irrigation canals also increases. Such an improper structure should be rearranged and efficient time, labor and capital use should be provided with modern agricultural practices. The objective in such practices should also be the optimum utilization of agricultural inputs to improve efficiency and yield levels in production activities and ultimately to improve life standards of rural people. Agricultural infrastructure should be rehabilitated to meet ever-increasing food demands of increasing population and to meet raw material needs of various industries. Rehabilitation of agricultural infrastructure requires integration and implementation of several inter-related eco...

Most of buildings in rural areas are made out of stone, hollow concrete blocks, adobe(mud bricks), brick and wood. But these materials do not have both sufficiently compressive strengths and thermal conductivity. The aim of this study was to investigate the effect of waste expanded polystyrene (WEPS) and pumice aggregate on strength and thermal conductivity of gypsum blocks. A lot of new wall materials can be made by mixing those materials in different volume fractions. The compressive strength, density, water absorption and thermal conductivity of samples produced were determined. It is observed that these EPS and pumice gypsum blocks have sufficient strength for their use in general building construction. The thermal insulation properties are quite good as a result of the thermal conductivity tests. This composite material is suggested for use in building applications as partitions.

This study was conducted to investigate the effects of the supplementation of fermented mealworm larvae meal with two different probiotic bacteria (Lactobacillus plantarum or Lactobacillus brevis) to diets of broilers reared normal or high stocking density on litter quality. Wood shavings, commonly used in broiler houses, are used as litter material. High stocking density significantly increased litter moisture content compared to that of broiler reared normal stocking density (P<0.0001). Dietary supplementing of fermented mealworm larvae meal with Lactobacillus plantarum or Lactobacillus brevis significantly decreased litter moisture content compared to that of control diet (P<0.0001). High stocking density significantly increased litter pH level compared to normal stocking density (P<0.0001). On the other hand, dietary treatments had no significant effect on litter pH. High stocking density significantly increased ammonia gas emissions in the 5th day (P<0.05) and 7th d...

Rural settlements are common in countries with economies largely dependent on agriculture and in countries where much of the population is employed in agricultural sector. Such settlements are also quite common in Turkey. Legal regulations on settlement-structuring are practiced exactly in the same fashion throughout the country in Turkey. Social, economic, geographical and environmental issues are not considered. Low life standards in villages due to insufficient social and technical infrastructure force rural people to migrate cities. The migration from rural to urban has still on-going since 1950s. Certain infrastructural services should be provided to rural settlements to keep them alive and allow them to perform functions and activities expected from them. Basic infrastructural services should be provided to rural people in order to let them to serve for the development of the country in concert with the other sections of the country. In this study, current status of rural sett...

Indoor and outdoor temperature and relative humidity are the most commonly used parameters in design of animal housing systems. However, these two parameters are not the only environmental parameters to be used in design of such facilities. Ventilation and lighting are also significant issues to be considered in design of animal housings. Ventilation is commonly performed to adjust indoor temperature and relative humidity and to remove hazardous gases, odor and dust from the facilities. Special attention should paid not to create dust while operation of livestock facilities. Noxious gases and odor should be removed regular operation of ventilation systems since they result in various health problems and animal mortalities at certain concentrations. In this study, besides basic design parameters, especially indoor air quality parameters of livestock housing systems were pointed out. Critical concentrations, harmful impacts of noxious gases, odor and dust on animal health and structur...

Greenhouse play significant roles in human nutrition. Vegetable and fruit consumption at certain amounts is the basic precondition for a well nutrition. It is possible to produce sufficient quantities of fruits and vegetables in places with available climate conditions. However, fruits and vegetables should be grown in special buildings to have a year-long production in places without available climate conditions. These places include undercover production facilities, greenhouses, low and high tunnel facilities. Environmental conditions are adjusted are adjusted in greenhouses as to provide proper conditions for plant growth and development. Ventilation is used to remove excess heat, moisture and carbon dioxide from the greenhouses. Either natural or mechanical ventilation is used in greenhouses. Mechanical ventilation systems have various advantages over natural systems. However, mostly natural ventilation systems are preferred because of their low installation and operational cost...

Use of renewable energy resources should be brought forward to reduce heating costs of greenhouses and to minimize the use of ever-depleting fossil fuels. Geothermal energy not only provides the heat required throughout plant growth, but also allow a year-long production. Geothermal resources with several other benefits therefore play significant role in agricultural activities. With regard to geothermal potential and implementation, Turkey has the 7th place in the world and the 1st place in Europe. Majority of country geothermal resources is used in greenhouse heating. The size of geothermal greenhouses increased 5 folds during the last decade and reached to 2500 decare. In this study, current status of geothermal greenhousing of Turkey was presented; problems and possible solutions were discussed..
