Son yıllarda sürdürülebilirliğin bir bileşeni olan sorumlu tüketim kapsamında sade yaşam tarzı ve kuşaklar arasındaki farklılıklar ilgi konusu olmuştur. Sürdürülebilir kalkınma amaçlarına hizmet eden sorumlu tüketim bağlamında gönüllü sade yaşam tarzı bir toplumun yapısı hakkında bilgi verme adına önemlidir. Her ne kadar gönüllü sade yaşam tarzı toplumsal yapı hakkında bilgi vermekle birlikte kuşaklardaki farklılaşmalar gönüllü sade yaşam tarzlarını etkileyebilmektedir. Bu makalenin amacı, X, Y ve Z kuşaklarına göre gönüllü sade yaşam tarzı arasındaki farklılıkları analiz etmektir. Çalışmada 21 maddeden oluşan Gönüllü Sade Yaşam Ölçeği ve 6 adet sosyo-demografik sorular kullanılarak yüz yüze ve sosyal medya aracılığı ile Türkiye-Sivas ilindeki 414 kişiden anket yoluyla veri toplanmıştır. Kuşaklar ile gönüllü sade yaşam tarzı arasındaki farklılığın anlamlılığını test etmek için Kruskal Wallis Testi kullanılmıştır. Araştırma sonucuna göre, X kuşağı gönüllü sade yaşam tarzını Y ve Z kuşaklarına göre daha çok benimsediği anlaşılmıştır. Buna benzer olarak Y ve Z kuşağı karşılaştırıldığında ise Y kuşağının Z kuşağına göre gönüllü sade yaşam tarzını benimsediği ortaya konuldu. Sonuç olarak X ve Y kuşağının gönüllü sade yaşama daha duyarlı olmasının nedeni tarihsel arka planındaki toplumsal sorunlarla karşı karşıya kalmış olması, zor zamanlarda yetişmiş olmaları ve hayat tecrübelerinin Z kuşağına göre fazla olması ile ilgili olarak açıklanabilir.

Changes in the landscape become extremely destructive and many heritage values and resources are irreversibly lost. The speed, frequency and magnitude of these changes in the landscape increased in the second half of the 20th century, especially with the impact of human activities. Remote sensing is the most widely used method for determining the change in the landscape. In the research, MNDWI, NDVI and NDMI techniques, which are frequently applied in remote sensing, were used in order to determine the landscape change in Salt Lake. Thus, the changes in the built area, water surface and land cover between the years 2000-2020 in Salt Lake were determined. According to the MNDWI and NDMI Analysis results, a decrease was observed in the water surface width and moisture content in Salt Lake between 2000 and 2020. In the steppe areas south of Salt Lake, the increase in tree cover due to the change in land use type was determined by NDVI analysis. Therefore, it is possible to say that there is an increase in the amount of moisture in these areas. In addition, it was determined that the increase in agricultural activities in the region caused a change in land use types and the amount of green space in the region changed at this rate. With the mentioned methods, negative changes in the landscape as a result of human activities on the landscape can be determined practically. Thus, it will be possible to predict the negative consequences of climate change and take precautions.

Healthy life in a sustainable environment is possible with accessible food production. The Covid-19 epidemic is a serious threat worldwide. This epidemic has revealed the importance of agricultural products. One of the most important areas of the epidemic affecting the whole world is exports; however, increased demand for agricultural products and exports in the epidemic process in Turkey. Turkey has a say in the trade of seedless dried grapes in the world. Seedless dried grape is on the healthy products list of the WHO. In 2019/2020, it had a share of 36% of world exports (with 246 thousand tons of export). This study was performed to evaluate their thoughts and farmers’ problems with the adoption of organic farming in Besni district of Adıyaman. The research conducted in-depth interviews with the farmers producing organic grapes. Also, a face-to-face survey was conducted with 50 farmers. According to the findings, the land width of the farmers is not much. It has an average growing area of 37.52 decares. An average yield of 1.808 kg da-1 is obtained from this area. Serious differences have been found between conventional and organic farming. Moreover, government supports, high product prices, income, health, sustainability, and environmental protection are reasons farmers switch to organic farming.  However, farmers argue that organic farming is less costly than conventional farming. Access to chemicals and marketing are major problems. As a result, farmers should be informed about organic farming. Additionally, it is thought that these studies will increase the productivity and product quality of the farmers. It is predicted that it will prevent rural to urban migration in the region.

The aim of this study was to determine the fertility, herd life and milk yield characteristics of Simmental (SIM) cows of Austrian origin, which have increased the interest of cattle breeders in Türkiye in recent years. From the records of the farm between 2011 and 2021, the first calving age (FCA), calving interval (CI), herd life (HL), productive life (PL), lactation length (LL), lactation milk yield (LMY) and 305 days milk yield (305-dMY) were calculated. A total of 307 FCA, 619 CI, 212 HL and PL, 447 LL, 271 LMY and 497 305-dMY data were used. The means of FCA, CI, HL, PL, LL, LMY and 305-dMY for SIM cows were 842.35±5.30 days (28.1 months), 422.98±3.18 days, 75.48±1.72 months, 47.15±1.73 months, 363.52±3.52 days, 10,596±152 kg and 8647.0±58.0 kg, respectively. Based on the long FCA and CI averages of Austrian-origin SIM cattle, although it can be interpreted that there are some problems in terms of reproductive efficiency in the farm, finding long HL and PL and high milk yield, it can be said that the farm contributes to the increase of milk yield per cow by turning the negativity caused by the reproductive efficiency into an advantage.

In recent years, intensive legal regulations aimed at the production of urban areas in Türkiye, the phenomenon of migration, the spread of higher education, abnormal cost increases in agricultural activities have accelerated urbanization. Parallel to the increase in the urban population, the food supply remains insufficient. The inability to increase the production of food products brings with it problems such as malnutrition, inflation, foreign trade deficit, food security. The natural areas harbored by rural and urban areas are shrinking and being destroyed by the pressure of rapid urbanization. In addition to the abandonment of rural areas, the food crisis that has arisen as a result of the intervention of the urbanization process in agricultural areas has increased the responsibility of the central government and municipalities. In order to meet the food needs of the population and implement sustainable agricultural policies, municipalities are taking different and innovative approaches. Municipalities are making direct and indirect attempts to provide people with cheap and reliable food. In this study, the activities carried out by the municipalities in Türkiye to support sustainable agriculture and their economic and social effects were examined.

In this study, 34 molds showing pectin degradation activity were isolated from the soil of orchards, by several tests.  By using these isolates, pectinase group enzymes; studies on pectin lyase and polygalacturonase production were performed in the batch system and under non-sterile culture conditions. 5 isolates denoting polygalacturonase activity were coded as: T1, T2, T3, T4, T5 and the best polygalacturonase activity among these isolates was determined as 354.4 U/L in T4 isolate. Thus, optimization analyses continued by the use of this isolate. Initial apricot pulp concentration, temperature, pH and incubation period were tested as optimization parameters. The effects on enzyme activities were investigated by changing the initial apricot pulp concentration in the range of 5-100 (g/L), and in this regard, polygalacturonase activity was determined as 397.4 U/L at 50 g/L. In addition, the pH parameter was analyzed in each unit between pH = 3 – 8, and the temperature was tested by increasing 5 units in the range of 5-25°C. Consequently, the maximum polygalacturonase activity was determined as 405.7 U/L at pH 5 and 406.3 U/L at 15°C. Besides, the effect of the incubation period was studied within 1-5 days and the maximum polygalacturonase activity was determined as 429.0 U/L on the 4th day (after 96 hours). As a result, the above-mentioned T4 isolate, with which the optimization studies were conducted, was identified as Sarocladium strictum (Top ekinküfü) T4 by molecular methods.

The study was carried out in a randomized plot design with three replications, with 4 pots in each replication and 3 plants in each pot. A total of 10 applications consisting of liquid compost (25%- 50%), vermicompost (25%-50%), and humic acid (600-1200 ppm) and combining these applications were applied to Zinnia seedlings. The first application was applied as 400 mL per pot when the plants reached 20 cm in size. Applications were made 3 times with an interval of 7 days. When the plants are harvested, flower diameter (mm), stem thickness (mm), number of flowers (piece), stem length (cm), number of branches (pieces), the weight of branches (g), number of leaves (pieces), root length ( cm), root fresh weight (g), root dry weight (g), vase life (days) parameters were examined. As a result of the study, the highest flower diameter (72.27 mm) and SPAD value (34.93) was 600 ppm humic acid application, the highest flower stem thickness (4.67) and flower stem length (45.56 cm) 25% liquid compost + 25% vermicompost application, the highest flower stem thickness (4.67). The number of flowers (6.17 pieces) and root wet weight (8.10 g) were found in 25% vermicompost application, the highest number of branches (7,25) in 1200 ppm humic acid application, the highest branch weight (30.76) in 50% vermicompost application. As a result, it was observed that in applications where 25% of vermicompost was used, it had positive effects on the number of leaves, flowering, and root parameters. In humic acid applications, it has been found to have a positive effect when used at low rates such as 600 ppm. It is stated in the results of the study that the doses used to give better results when applied at low rates.

Drought is one of the most prevalent forms of abiotic environmental stress that reduce crop productivity. A pot experiment was performed in two Aman seasons under drought (40% field capacity, FC) and control (100% field capacity, FC) irrigations to study drought tolerance mechanism(s) based on morphological and physiological traits in six aromatic rice genotypes. Twelve treatments (6 genotypes × 2 irrigations) were arranged in Complete Randomized Design and experiment was carried out at Bangladesh Institute of Nuclear Agriculture, Bangladesh Agricultural University, Mymensingh. In the experiment, drought was imposed at panicle initiation stage where morphological and physiological data were recorded. Important morphological (stem and root dry weight) and physiological (photosynthesis and chlorophyl content) attributes were significantly (P>0.05) decreased at 40% FC in both the years. Compared to control, relative reduction at 40% FC in above parameters, genotypes were classified into tolerant (Binadhan-13 and NERICA mutant) and sensitive (RM-100-16, Ukunimodhu, Kalizira, and BRRI dhan34) categories. Tolerant genotypes had smaller reduction in shoot and root dry mater (av. 7.73 and 5.56 %, respectively) than sensitive ones (av. 19.32 and 21.80%, respectively). Low reduction percentages of the traits under drought stress to that of the control discriminated Binadhan-13 and NERICA mutant genotypes consistently as drought tolerant.
