Cultivation and consumption of berry fruits in the world and in our country is increasing due to reasons such as different ways of evaluation, high income per unit area and health benefits. Aronia, which belongs to the Rosaceae family, is a berry type that can be easily grown in temperate climates and has a high yield per unit area. Aronia is included in healthy nutrition programs due to the antioxidants, phenols, minerals and vitamins it contains. Besides fresh consumption, aronia fruits are also used by drying, processing into products such as fruit juice, vinegar, jam, tea, marmalade.

Organic agricultural products are food products that are inspected and certified at all stages of production until they are offered for consumption by institutions that are authorized by the state. Beekeeping products made for human food are also subject to the same certification process. With this research, it was aimed to reveal the organic beekeeping and organic honey understanding of the people of Iğdır region. With the survey, the information of the local consumers about organic honey, how they got this information, their status and reasons for organic honey consumption, as well as the certification processes were collected. The obtained data were analyzed with numerical, proportional, and decision tree methods. The genders of the survey participants were 66% male, 34% female. It was also determined that 70.5% of the participants were under the age of 40, had a bachelor's degree or higher education level in the proportion of 43%, and 63% had a minimum wage or lower-income level. For the questions asked about the research topic, it was reported that participants know and eat organic honey in the proportion of 93%, buy organic honey in the proportion of 77.5%, having information about the organic honey certificate in the proportion of 67% and certification stages in the proportion of 43%. Despite these high rates, the same participants gave contradictory answers to some other questions, such as; for the question of “What is organic honey?” the answer of "Certified honey" in the proportion of only 11.5% and for the question of “How did you know that the organic honey you bought was organic honey?” the answer of " I saw its certificate” in the proportion of only 18.1%. This contradiction was noted. With this research, it was determined that the local people did not have enough information about organic beekeeping and honey understanding. In order to fill this gap, it can be suggested that healthy nutrition lessons be included in the education curricula starting from primary school, and usage of TV, radio, and internet broadcasting for this purpose. The fact that the participants' education level is high and their age is young may provide an advantage in order to get results from the training to be given on the subject.

The study aims to investigate the monthly changes in the prices of culture fish that were sold in retail fish outlets in Sinop in 2019 and determine the correlations between the prices of the species. The retail outlets were determined using stratified sampling and divided into three groups as I (high), II (medium), and III (low) with respect to their product range and sale amounts. Each sale group was represented by two independent retail outlets. The prices were determined twice a month at the same time of the day during the study. The retail outlets were determined to sell sea bream (Sparus aurata), sea bass (Dicentrarchus labrax), and rainbow trout (Oncorhyncus mykiss) culturing of which are carried out in Turkey. The difference in the monthly prices of the species was not statistically significant. There was a positive and moderate relationship between the prices of sea bream and sea bass (r=0.69), a positive and strong relationship between the prices of sea bass and trout (r=0.85), and a positive and strong relationship between the prices of sea bream and trout (r=0.71).

Turkey as well as in the developing world science, technology and the changing rural development and manufacturing approach accordingly with industry, has changed the shape of the realization of agricultural activities. As a result of new production methods, environmental and human health deteriorated and scientists have turned to organic agriculture. Organic farming practices, which started in the 1980s in our country, have improved significantly with the publication of the organic farming regulation in 1994 and the regulation was last regulated in 2018. Our country with conditions favourable for organic agriculture in terms of soil and water resources, climate, variety of products, this study was prepared in order to see how organic agriculture has progressed over the years and at what stage it is today. In 1990, 8 organic products were produced in Turkey with 313 farmers in an area of 1,037 ha. According to the latest data 73,563 farmers have grown 2,371,612 tons of organic products in 626,885 ha organic agriculture area. In addition, the organic product range produced was increased to 213. When we look at the export situation, it is seen that the total export amount is 111,690,675 tons and a significant amount of this export amount is 41.633,896 tons of wheat and wheat products. Looking at the import data, it is known that the total import amount is 175,865,85 tons and the most imported product is soybeans (non-seed) (99,446 tons). Although a significant increase in organic agriculture production has been observed compared to previous years, it is anticipated that this increase may increase even further considering Turkey's agricultural potential.

Tokat, which is located between the Black Sea Region and the Central Anatolia Region and has a transition climate, is one of the provinces with high agricultural potential. This potential also provides important advantages in terms of vegetable agriculture. In Tokat, where the vegetable cultivation dates back to many years, many types of vegetables can be grown. While the farmers engaged in vegetable cultivation until the beginning of the 2000s were satisfied with their situation, in the last 15 years, growers have started to turn to alternative products due to the decrease in quality, productivity and profitability. There are significant difficulties and decreases in competitiveness of vegetable farming in the field and greenhouse cultivation. In the study, strengths, weaknesses, opportunities and threats of vegetable cultivation of Tokat were analysed. Solutions for the improvement of vegetable cultivation have been discussed by making determinations.
