2020
Aybike Bayraktar | Ismet Boz
While the use of pesticides in plant production has positive effects on yield and quality, it has negative effects on human and environmental health. The environment is polluted by the intense and unconscious use of chemicals in agriculture, and the absence of environmentally friendly agricultural methods. This causes problems in the long term, such as reduced biodiversity and disruption of natural balance. This study is important because there are many problems such as the producers' failure to effectively apply methods of combating diseases, pests, and weeds in agricultural production, the use of unnecessary and wrong doses of pesticides, and the methods other than chemical control are not preferred. The aim of this study was to examine the attitudes and behaviors of farmers towards use of pesticides in Çarşamba District of Samsun Province. For this purpose, a survey was conducted with 112 farmers determined by stratified sampling method. According to the findings, most of the farmers in the region do not prefer other methods different form chemical control methods. While farmers found the effectiveness of pesticides at a medium level, they found the price levels of pesticides high. While there is a perception that over-using pesticides adversely affects the environment, biological control methods are not known enough. Various research, education, and extension studies should be carried out for farmers to use pesticides more consciously, and to apply methods other than chemical control.

2020
Gülsevim Tiring | Serdar Satar | Okan Özkaya
Bark beetles (Coleoptera: Curculionidae) are among the important pests of forest in the world and in Turkey. Pine-feeding bark beetles interact chemically with their host tree via the behavioral, physiological, and biochemical effects of one class of monoterpenes. The half of oleoresin producing by trees such as pines, spruces, firs in the forests is the monoterpene. The monoterpenes occur in the oleoresin and function as behaviorally active kairomones for pine bark beetles and their predators, presenting a classic example of tritrophic chemical communication. The monoterpenes are aggregation pheromones for pine bark beetle. In the control of bark beetles, monoterpenes are used in traps. For example, the monoterpenes are an attractant for bark beetles. Also, Myrcene is used for a synergistic effect in the trap. Monoterpenes can toxic to insects. Limonene is among the most toxic monoterpenes to bark beetles. Also, the interaction is found between monoterpenes and prey of bark beetle. Monoterpenes are enhanced to respond of predatory to the pheromone of bark beetle.

Aykut Burgut
The polyunsaturated fatty acids (PUFA) of lipids in muscle of sardine were known as unstable to oxidation. Propolis is a natural compounds produced by honey bees from substances collected from parts of plants, buds, and exudates. Nowadays, the particular attention has been attributed to propolis underlying their antioxidant properties due to the presence of the flavonoids, phenolic acids, and ethers. The impact of water and ethanolic extract of propolis at doses of 0.4 and 0.8% on fatty acid changes of vacuum packaged sardine fillets were investigated during chill storage. The main fatty acids in sardine fillets were palmitic acid (C16:0), palmitoleic acid (C16:1), myristic acid (C14:0), eicosapentaenoic acid (EPA, C20:5n3) and docosahexaenoic acid (DHA, C22:6 n3), respectively. There was no significant differences in EPA and DHA between control and treated groups during storage apart from 4 and 11th day. Initial n6/n3 ratio in sardine fillet was 0.17. Group treated with 0.4 propolis ethanolic extract comprised lower n6/n3 ratio at 4, 11 and 13th days than that of other groups. Although the effects of propolis extracts on fatty acid composition of fish were variable, application of propolis ethanolic and water extracts on fish fillets at doses of 0.8% had a positive impact due to lead a better oxidative stability of PUFA content.

Serpil Yılmaz | Mustafa Tunca Olguner
The fisheries sector makes significant contributions to the economy for the animal nutritional needs of the people, industry, employment and national income. In particularly the aquaculture sector is one of the fastest growing sectors in Turkey with a growth rate of 11%. Antalya is one of the provinces with an importance in the aquaculture sector. Unfortunately, it is not possible to use this potential efficiently either as the province is also a major tourism destination. As a matter of fact, cage nets in the province have been moved to further locations due to tourism. However, there are still 78 active aquaculture facilities in Antalya, including 73 trout and 5 seabream-seabass. These businesses are performing about 2% of Turkey's aquaculture production. As of 2017, aquaculture production amount in the province was 5,693 tons/year. There are 5 fishing shelters in Antalya in 2017. These are located in Konyaalti, Alanya, Finike, Kas (Center) and Kas (Kalkan) regions. However, the number of landing points cause some confusion and problems in terms of control. For this reason, it is requested to open a Seafood Wholesaler in the province. The fisheries and aquaculture production was 6,779 tons/year in Antalya and 1680 tons in 2016, 1898 tons in 2017 and 2359 tons/year as of 2018 were exported.

Süleyman Avcı | Onur İleri | Ali Koç
In this study which was carried out during the 2015 summer season in Eskişehir, the flower, pod and seed characters attributed to yield components were investigated in 12 forage pea genotypes. They showed significant differences in terms of agronomic and morphological (flower, pod, and seed) traits. The highest fresh hay yield with 2171 kg/da and plant height with 106.6 cm were obtained from Populasyon-1. Crackerjack had lower values in some flower traits such as, whereas the higher values of pod and seed traits were obtained from cv. Rose. In addition, Population-1 included in the higher value group for standard petal width, keel petal length, calyx tube and teeth lengths, and flower length. Although cluster analysis did not reflect agronomic traits, the clustering resulted in four groups. The first group consisted of Özkaynak 1, 2, and 3 and Taşkent, Töre, and Population-2, which were the standard petal colour violet, light, and dark violet. Population-1 had both violet and white standard petal; however, it was included in the second group together with white-flowered Ulubatlı and Ürünlü according to cluster analysis. While Rose and Gölyazı were in the third group, Crackerjack was in the fourth group alone. There was a highly significant positive correlation between fresh hay yield and both standard petal width and length and flower length. Consequently, a hopeful result for summer growing in Eskişehir condition was obtained from Population-1. It was suggested that some flower characters can be used for pre-selection of yield-related traits in the evaluation of genetic diversity of pea germplasm through morphological trait.

Hikmet Günal | İsmail Çelik
In this study, the effects of two traditional, three reduced and a zero tillage methods applied for nine years on GEA and PMN were determined and compared. The study, initiated in 2006 as randomized block design, includes a total of 18 plots with 3 replications for 6 different soil tillage systems. In the study, six different soil tillage methods are applied, namely conventional tillage with stubbles (CT-1), conventional tillage with stubbles burned (CT-2), reduced tillage with heavy disc harrow (RT-1), reduced tillage with rototiller (RT-2), reduced tillage with heavy disc harrow (RT-3) and no tillage (NT). Winter wheat was grown as the main crop every year or corn and soybean was grown following the harvest of wheat (second crop) every other year. Differentiation of tillage systems led to a significant variation in GEA and PMN concentrations. The GEA concentration, which increased significantly with the decrease in tillage density, varied between 44.68 mg PNP kg-1 h-1 (CT-2) and 207.66 mg PNP kg-1 h-1 (STI). However, the trend determined in GEA could not be detected in PMN. Although PMN concentration was significantly higher in soils under NT, it was included in the same statistical group with RT-1 for PMN concentrations. Higher PMN concentration in no till soils can be possibly related to the non-disturbance of soil structure. The results of study revealed that reduced and no tillage systems are extremely necessary to increase the quality of soils in the region.
