In this study, Bomolochus unicirrus Brian, 1902, a species of parasitic copepod belonging to the family Bomolochidae (Claus, 1875), was reported for the first time from the north-eastern Mediterranean waters off the Turkish coast. Parasites were collected from the gill filaments of the European barracuda, Sphyraena sphyraena(L.)captured by trawling in Iskenderun Bay, Turkey. The morphological features of B. unicirrus were Redescribed and illustrated based on the newly collected material. Key diagnostic characters and newly observed details in some structures are highlighted and supported by using scanning electron microscopy (SEM). Differences and simply overlooked details in previous descriptions of B. unicirrus, are discussed in detail. In addition, morphological comparisons between presently reported species and the other species of the genus Bomolochus Nordmann, 1832 were also presented.

Children's playgrounds which are safe and quiet environments that children can play there have started to become rare as a result of rapid urbanization. Because, the studies have shown that unplanned and distorted urban spaces affect children's behaviours, attitudes and reactions in a bad way. In this study, the availability of children's playgrounds in 22 districts of the city centre of Ordu was investigated. In this context, firstly, children's play areas were determined based on the neighbourhood scale and then area calculations were made and the amount of play area by per child between 0-14 years was calculated in each district. In the second stage, accessibility maps for children's playgrounds were obtained by determining the availability of the playgrounds at 200m distance. The results of this study showed that children's playgrounds are not balanced in the city, increased in some districts, in some cases they are not within reachability limits and can not meet their needs.

Fotoperiyodizm, mevsimlik çiçeklerde çiçeklenme zamanını kontrol etmek için kullanılabilecek bir özelliktir. Kadife, mutlak veya fakültatif kısa gün ve nötr gün çeşitleri içeren bir yazlık mevsimlik çiçek türüdür. Aşırı sıcak ve uzun günlerin yaşandığı yaz aylarında nötr gün çeşitlerinde bile çiçeklenmede gecikmeler yaşanmaktadır. Bu çalışmada iki farklı nötr gün kadife çeşidinde (Discovery Orange ve Discovery Yellow) fotoperyodik koşulların (kısa gün ve uzun gün) çiçeklenme ve bitki gelişimi özellikleri üzerine etkileri araştırılmıştır. Uzun gün koşulu (14 saat) olarak doğal gün uzunluğundan yararlanılmıştır. Kısa gün koşulu (8 saat) ise karartma yapılarak yapay olarak oluşturulmuştur. Bitkilerde ilk çiçek tomurcuğu oluşma süresi, ilk çiçek açma süresi, bitki taç yüksekliği, bitki taç genişliği, yan dal sayısı, çiçek sayısı, ana çiçek sapı uzunluğu, çiçek sapı kalınlığı, kök boğazı kalınlığı, gövde kalınlığı ve bitkisel kuru ağırlıklar (kök, yeşil aksam ve tüm bitki) incelenmiştir. Araştırma sonucunda kısa gün koşulunun, ilk tomurcuk oluşma ve ilk çiçek açma sürelerini azalttığı belirlenmiştir. Yapay olarak yaratılan kısa gün koşulu, uzun gün koşuluna göre çiçeklenme süresinde ‘Discovery Orange’ çeşidinde 13 gün, ‘Discovery Yellow’ çeşidinde ise 5 günlük bir erkencilik sağlamıştır.

In this research, it was aimed to determine the adsorption, saturation reaching and desorption effects of ammonium, which is one of the parameters that should be kept in control for aquarium life, by clinoptilolite type zeolite which is a natural filtration material. In the aquarium water, Z1: 20 mg/l TAN and Z2: 40 mg/l TAN concentrations were determined to have adsorption up to Z1: 10 mg/l TAN and Z2: 24 mg/l TAN concentration at the end of the experiment period. After this phase, where zeolites had reached saturation, desorption system was created, and 2 groups were formed with 5-liter research aquariums and 3 repetitions. During the five-days test, water parameters were determined daily and at the same time of day (10.00). At the beginning of the experiment, mean values of 0.4 ± 0.00 mg / l TAN in Z1 and Z2 groups were determined at the end of the experiment as 1.55 ± 0.176 mg/l (15.5%) and 2.153 ± 0.27 mg/l (13.5%) TAN in Z1 and Z2 groups, respectively. When the data obtained in this study were evaluated, zeolite was determined to make desorption periodically in proportion with the amount of retained ammonium, when it reached the saturation. In intensive aquaculture systems or aquarium conditions, recondition of zeolite for necessary periods is recommended to be performed by considering these data.

This study was carried out to elucidate the impacts of zinc (Zn) treatments on growth, development, quality and yield of commonly sown bread wheat cultivars under field conditions of Çukurova Region. Three different bread wheat cultivars (Adana-99, Ceyhan-99 and Pandas) were experimented in randomized complete blocks-split plots experimental design with 3 replications. Field experiments were performed by two different Zn application methods; via soil and via soil+foliage. In the both trials, 0, 5, 10, 20, 30, and 40 kg ha-1 pure Zn doses were applied to the soil. 0.4% ZnSO4.7H2O solution was used for foliar Zn applications. Current findings revealed that Zn treatments had significant effects on grain yield, grain Zn concentration, grain phosphorus (P) concentration and thousand grain weight of bread wheat cultivars, but significant effects were not observed on grain protein concentrations. Soil+foliar Zn treatments were more effective in improving grain Zn concentrations. It was concluded that 10- 20 kg ha-1 Zn treatment was quite effective on grain Zn concentrations.

Turkey has almost 70% of world hazelnut production and 80% of hazelnut export. Ordu has the privilege of being the city which has the greatest area with hazelnut by supplying the 33.7% of hazelnut production. The income source of 70% of the people in Ordu is hazelnut and for this city, hazelnut is not only an agricultural product, it is also a national asset. There are 40 hazelnut processing plants with an internal capacity of 350.000 tons annually. 32.5% of these plants are in Ordu. When the top 20 Black Sea Hazelnut and Products Exporters Union member firms with the highest hazelnut export in 2016 were analyzed, it was found that 7 of these firms are in Ordu. These 7 firms in Ordu cover the 11.84% of the total hazelnut export value, which is 1.981.334.911$ for 2016. The purpose of this study which will be discussed within this context is to analyze and show the current states of hazelnut processing plants in Ordu in terms of product processing, quality assurance and standards and marketing. The data obtained as a result of the study will be used to find out the tendencies of the plants in the coming years. Because of this, the study is important in terms of researching the obstacles in increasing the export shares of hazelnut, which is one of the most important export products of Turkey economy. For this purpose, a face-to-face questionnaire was conducted with the managers and authorities of 12 hazelnut processing plants in Ordu. It is expected that the information presented within the context of the study will develop the hazelnut processing industry and will lead the related people researching in this field.

New plantain hybrids plants have been developed but not much has been done on the post-harvest keeping quality of the fruits and how they are affected by microbial colonization. Hence fruits from a tetraploid hybrid PITA 2 (TMPx 548-9) obtained by crossing plantain varieties Obino l’Ewai and Calcutta 4 (AA) and two local triploid (AAB) plantain landraces Agbagba and Obino l’Ewai were subjected to various concentrations of acetic, sorbic and propionic acid to determine the impact of chemical concentration, chemical type and plantain variety on ripening and weight loss of plantain fruits. Analysis of titratable acidity, moisture content and total soluble solids showed that there were no significant differences between fruits of hybrid and local varieties. The longest time to ripening from harvest (24 days) was achieved with fruits of Agbagba treated with 3% propionic acid. However, fruits of PITA 2 hybrid treated with propionic and sorbic acid at 3% showed the longest green life which indicated that the chemicals may work better at higher concentrations. The Obino l’Ewai cultivar had the highest weight loss for all chemical types used. Modelling data obtained showed that plantain variety had the most significant effect on ripening and indicates that ripening of the fruits may depend on the plantain variety. It appears that weight loss of fruits from the plantain hybrid and local cultivars was not affected by the plantain variety, chemical type. The chemicals at higher concentrations may have an effect on ripening of the fruits and will need further investigation.

Wireless sensor networks applications and inter-machine communication (M2M), called the Internet of Things, help decision-makers to control complex systems thanks to the low data-rate and cost-effective data collection and analysis. These technologies offer new possibilities to monitor environmental management and agricultural policies, and to improve agricultural production, especially in low-income rural areas. In this study, IoT is proposed with a low cost, flexible and scalable data collection and analysis system. For this purpose, open source hardware microprocessor cards and sensors are stored in the greenhouse computer database using the IEEE 802.15.4 Zigbee wireless communication protocol. The data can be analyzed by greenhouse computer analysis software, which is developed with the PHP programming language. It is possible to monitor the real time data from the greenhouse computer. Also alert rules definitions can be made and the system was tested in greenhouse conditions. It has been observed that it performs operations steadily such as data transfer, sensor measurements and data processing. The proposed system may be useful for monitoring indoor climate and controlling ventilation, irrigation and heating systems, especially for small enterprises due to the modular structure.

The research was conducted with the aim of determining the social and economic factors which are effective on the adoption of new technologies at dairy farms in the province of Konya. The data used in the research was obtained on a volunteer basis by questionnaire technique from 128 dairy farms determined with stratified sampling method that is one of random sampling method. 51.56% of enterprises investigated were high innovators and 48.44% of enterprises were low innovators. In conclusion, it was determined that the milk yield, enterprise income, education of enterpriser, family size, number of animals, existence of land, case of receiving services of consultancy and frequency of using mass media tools made positive contributions to adoption of innovations by enterprises in the research field. But the training level decreased as the age of enterpriser increased in the research field. This case retards the adoption process of innovations and deescalates the use of new technologies in the enterprises. The young farmers come to the forefront in the adoption and implementation of innovations.
