Mehmet Cetin
People are with overall nominal temperature, precipitation, humidity and where in certain ranges of environmental conditions such as wind they feel healthy and dynamic. In the appropriate range for the people of these values it is called the bioclimatic comfort. When bioclimatic comfort area is in the range of fair value would bother people in the area and want to get away from the area. Hence bioclimatic comfort areas used for the purpose of tourism is very important. In this study, Kastamonu-Cide bioclimatic comfort is done mapping of the coastline and thus aimed at building pad similar studies of a similar nature in the coastal areas. For this purpose, the region's climate data Cide is located; equivalent temperature according to the physiological index is bioclimatic comfort maps were prepared. To determine the structure of the field is bioclimatic comfort is collected climatic data from meteorological stations. The obtained data were evaluated by means of Rayman 1.2 and geographic information system (GIS) is used to produce thermal perception map with the help of software. According to the psychological equivalent temperatures As a result, the most appropriate time and area for outdoor recreation activities have been identified by thermal perception maps.

According to the scientists, the world's population by 2050 is estimated to exceed 9 billion, in order to meet the nutritional needs of people, it is expected that in the future to need more food production than today. Therefore in the world, food organizations, institutions and communities various action plans provide in the reports published. In these plans, diversification of the production, fast, quick and easy way to produce food, less harmful farming practices to the nature and the environment, and etc. topics are included. In line these plans with last years, the greater the number of species used as food and with ease of cultivation, mushrooms and mushroom cultivations are gaining importance. For this purpose, the determination of the diversity of edible mushrooms in nature and investigation that how can be taken to culture, it will also provide support to the production of different species of mushrooms. In the field studies performed between 2011 and 2013, after taking pictures on their habitats mushroom samples, collected within the Çorum province limits, were brought to the laboratory wrapped in aluminum foil properly. After measuring and studying on special structures under a microscope in the laboratory, they were identified according to the literature. Fungarium tag were prepared for identified mushrooms. These mushrooms, made into the Fungarium materials, were stored in Fungarium of the Directorate of Mushroom Application and Research Centre of Selçuk University. In conclusion, according to the literature four taxa belong to Ascomycota and 52 taxa belong to Basidiomycota, in totally of 56 taxa were found to be edible feature. These 56 taxa were represented by two divisio, four ordo and 14 families. The localities of identified species in the provincial boundaries are given.

Because of using sulphur free fertilizer, rice crop facing tremendous sulphur (S) deficiency throughout the world as well as in Bangladesh. However, farmers of Bangladesh often overlook the importance of sulphur fertilization on rice yield. Therefore, the present study was conducted to investigate the influence of different levels of sulphur on growth, yield attributes and uptake of N, P, K and S by grain and straw of BRRI dhan41 rice variety. The experiment was laid out in randomized complete block design with three replication and eight treatments including control. The result of the study revealed that the highest plant height, panicle length, filled grain was found in T1 (50% RFD of S) treatment, while the utmost number of effective tiller and straw yield was recorded in T5 (150% RFD of S) treatment. Interestingly, maximum grain yield as well as uptake of N, P, K and S by grain and straw was significantly higher in T6 (175% RFD of S) treatment. The highest grain yield of T6 treatment might be due to maximum nutrient use efficiency. However, in all cases control treatment (T0) gave the worst result. The present study clearly indicates that higher rates (175% of the recommended dose) of S along with other fertilizers may be recommended for better growth and yield of BRRI dhan41 in Bangladesh soil.

Binary logit regression model of econometrics was used to identify the factors affecting adoption of recommended agricultural technology by the commercial farmers of Nepal. A survey was carried out in 2012 in 120 households from Kavre district, Nepal. The objective was to appraise factors affecting adoption of recommended technology of cauliflower, finding out the level of adoption, identifying the constraints of cauliflower cultivation, assessing the perceived level of satisfaction and studying the relationship of certain selected variables on the adoption. Education, Occupation, contact with Personal Localite sources of information, Group membership and Experience were the most influencing factors for adoption of recommended technology. Though, other factors were not strong enough to contribute significantly but indirectly influence the adoption decision of farmers as combined effects. Occupation was found as negatively associated. Landholding size was strongly and positively influencing among the non significant factors. The level of satisfaction and the constraints of cauliflower production were also identified. Transfer of technology will be effective if and only if the client adopts the technology. For an effective transfer of technology, it is better to go for activities for the welfare of the socioeconomic factors of the farmers.

Increasing of industrialization and population has resulted in the accumulation of a wide variety of chemicals. Especially, widespread use of synthetic and toxic chemicals have led to an effort to improve new technologies to reduce or eliminate these contaminants from the environment. Chemical methods that used for the treatment of toxic materials are expensive, time-consuming and difficult, especially in extensive agricultural areas. Furthermore these methods led to formation of new chemical pollutants. Recent years, one promising alternative treatment method is to use of microorganisms for the biodegradation of these toxic chemicals. This method is effective, minimally hazardous, economical, versatile and environment friendly. In this study, we thought that microflora of insecticide resistant insects may be a potential reservoir for the isolation of new bacteria that can be used for the biodegradation of insecticides. In this research work, totally 24 bacterial isolates capable of biodegradation α-endosulsan were isolated from the body microflora of insects belong to Orthoptera, Dermaptera, Mantodea and Hymenoptera orders. Based on the some morphological, physiological and biochemical characteristics and fatty acid profiles they were identified as Stenotrophomonas, Pseudomonas, Acinetobacter, Bacillus, Brevibacillus, Flavimonas and Rhodococcus. As a result, these isolates can be used for the treatment of α-endosulfan residues at different environments.

This study was conducted to evaluate the effect of NK chemical fertilizers in combination with compost on the growth and yield attributes of tomato (Lycopersicon esculentum Mill.). The pot experiment was done in a complete randomized block design possessing eight treatments with four replicates. Fruit weight, pulp weight, seed weight, total soluble solid, leaf area and dry weights of plat parts were taken and fruit yield was calculated. All the collected data were subjected to statistical analysis. The results revealed that there were significant differences in fruit and seed weights, total soluble solid, pulp weight, 100 seed weight, pulp consistency, leaf area and crop residue. In these parameters, higher mean values were recorded in chemical fertilizers (7.5 g N + 6 g K2O + 15 g P2O5 per m2) with compost (2 kg per m2) than those in the chemical fertilizers applied alone (9.0 g N + 8 g K2O + 15 g P2O5 per m2as standard control). Total soluble solid and fruit yield were 5.73 obrix and 3.21 kg/m2 respectively in the chemical fertilizers with compost (7.5 g N + 6 g K2O + 15 g P2O5 +2 kg compost per m2) treated plants and these were statically on par with the standard control which gave 4.36 obrix total soluble solid and 3.05 kg/m2 fruit yield. The result could be concluded that application of chemical fertilizers (7.5 g N + 6 g K2O + 15 g P2O5 per m2) with compost (2 kg per m2) could increase the total soluble solid and fruit yield as well as reduce the usage of chemical fertilizers in tomato cultivation over the standard control in sandy regosol.

The most extensive and effective environmentally controlled production takes place in greenhouses. New innovations and developments for greenhouse production go hand in hand with efforts for sustainability. The greenhouses must be heated to ensure high yields and high quality. However, high heating cost (20%-60%) adversely influences production. Costs Sustainability of greenhouse production can only be maintained with increase of energy efficiency. Use of renewable energy sources in place of fossil fuels is only means to increase energy efficiency. In this work, fossil fuels and geothermal energy used for heating of greenhouses are compared based on production cost and CO2 emissions to atmosphere. The results showed that greenhouse production in Aydın with geothermal energy price of 0.06 ₺/kWh will be very advantageous compared to greenhouse tomato production in Kütahya, which can only compete with that in Antalya. Carbon dioxide emission in plastic greenhouses with double layer PE plastic heat insulation in Kütahya was 199.4 kg/m2 when imported coal was used for heating. The emissions in similar type plastic greenhouses, again heated with coal, in Aydın and Antalya were 74.4 kg/m2 and 55.5 kg/m2, respectively. Greenhouses in geothermal energy rich areas will be very advantageous, based on cost of production and CO2 emission, compared to that in Antalya region if they are heated with geothermal energy.

Erkan Eren | Gölgen Bahar Öztekin | Yüksel Tüzel
The commercial production of cultivated-mushroom, which has a forty years of past in Turkey, was started after 1980s. Until the recent decade, most of the total amount of production in Turkey was performed by family members while the cultivation of the product has gained an upward trend since the beginning of 2000s, though the amount and development rate were not enough. During that time, a number of large (>2000 m2) and medium (500-2000 m2) scale mushroom production facilities were established and Turkey has gained an important place in mushroom production in the world. In this study, we aimed to reveal the common production methods of ten medium and large scale mushroom companies whose daily production capacities are above 1 ton in six regions. In this respect, all companies have been visited and communicated directly with company representatives and a survey comprising 65 questions about company, production facility, compost and casing soil, production systems, diseases and pests and packaging was made. The findings have suggested us that such companies have mostly a history of 15 years of time and have a land size of 10-50 thousand m2, while their mushroom production areas vary between in size and that they make use of technology in production and automation in their plants and they have quality management systems (ITU, ISO 9001, ISO 22000 and Global Gap ) and they employ generally qualified and experienced technicians or agriculture engineers and also that 40% of them receive consultancy and also that they use their own productions or standard ready mycelium planted compost and that they use domestic peat as casing material and that they package the mushrooms with their brands and sell to markets mostly and lastly that they conduct pre-sale quality sorting and grading. It was also seen that there is lack of food engineers employed and most of the companies do not receive consultancy, and that the waste compost is not evaluated correctly and that the covering material is not in the required standards and that there are even companies not doing any water analysis and that coal for heating and chemicals for disinfection are used and that diseases and pests are inevitable and last that they lack in processing different products.
