Dilek Kabakcı | Soner Çankaya | Gökhan Akdeniz | Engin Derebaşı
Honey is the most known and consumed bee product by consumers. Therefore, from the past to the present, the investigation of the factors affecting the supply and consumption of honey has been on the agenda of the researchers. For this purpose, in our survey study, the effects of honey sales carried out via television channels (commercials) on consumers were investigated. According to the survey results, it was determined that 87.91% of consumers had a negative view about honey sales performed via television, 3.54% had a positive opinion, and 8.55% had no opinion on the issue. It was found that 5.83% of consumers bought honey through television commercials, and the education, income, gender and number of individuals in their households have an effect on the tendency to buy honey. Regarding the exposing of companies selling fake or adulterated honey by the Ministry of Agriculture and Forestry, results showed that this situation positively affected 54.53 of consumers in terms of trust in honey positively, affected 13.30% of consumers negatively, and did not affect 13.30% of consumers in any way. As a result, deceptive honey commercials lead to consumer abuse and create an environment of distrust of honey. In order to minimize speculation on honey, it is seen necessary to increase deterrent penalties for businesses that lead to unfair competition.

Aybüke Kaya | Songül Bay
This study was carried out to evaluate the socio-economic structure and organic farming activities of grape producers in Besni. A face-to-face survey was conducted with producers producing organic grapes. Data were obtained by interviewing a total of 50 producers. The number of organic products grown between 2005 and 2018 increased from 205 to 213 in Turkey. The number of producers engaged in cultivation in this area has increased more than 5 times compared to 2005. It reached nearly 80.000 in 2018. The area of organic vegetable production increased from 203.811 to 626.884 hectares in Turkey. While the production area increased 2.5 times, the production amount increased almost 4 times. Today, a variety of products in organic vegetable production, planting area, the number of farmers has increased in Turkey. The findings were obtained education level of the producers, the number of individuals in the family, record keeping, annual total income, newspaper reading, grape yield, grape cultivation area, property and rental land, credit usage, weed control, organic farming knowledge level, organic farming by using variables such as thoughts and grape variety. There are serious differences between conventional agriculture and organic farming. The family structure is effective in production activities. It has been determined that the thoughts of organic farming have changed depending on the age and experience of the producers. Organic grape producers have turned to organic farming due to their desire to sell their products at higher prices with state supports. Also, it has been suggested that organic farming is important in terms of the sustainability of living life all over the world. Increasing producer income and environmental awareness are among the main reasons for the transition to organic farming.

2020
Fatih Hancı | Gizem Tuncer
The aim of this study was to investigate the effects of exogenous Melatonin (100, 300 and 500 µM) and L-tryptophan (125, 250, 375 ppm) applications on some growth parameters of lettuce plants grown under salt stress. The study was carried out under semi-controlled greenhouse conditions in spring (March/April) season. The exogenous applications to lettuce plants were carried out two times as foliar spraying. Salt stress was generated by adding NaCl (0 mM, 100 mM, 200 mM) to irrigation water. The complete randomized design was used with three replications in this experiment. At the end of the study, it was found that the highest doses of exogenous applications had the highest effect on the parameters of the number of leaves, salinity necrosis, fresh leaf weight, fresh root weight, and total surface area of lettuce plants under 200 mM salinity condition. When the effects of the subtract on these values were compared, the effect of melatonin was found to be more pronounced. Leaf width, leaf length, and leaf surface temperature values were not affected by the external application. These values only changed depending on salt concentration. As a result of the study, it was concluded that the application of 500 µM melatonin significantly increased salt tolerance in lettuce plants. However, in order to reach a more general conclusion, the dose ranges and genotype/variety numbers should be increased.

2020
Kamile Ulukapı | Ayşe Gül Nasırcılar | Zehra Kurt
This study was conducted to determine tolerance levels of different radish varieties (white, black, red, little red radish) under salt stress conditions and to evaluate the effectiveness of exogenous salicylic acid (SA) application on germination and vegetative development. For this purpose; germination percentage (%), germination time (day), germination index calculated, and then number of leaves, shoot length (cm), root length (cm), leaf width (cm), leaf length (cm), stem diameter (mm), plant fresh and dry weights (g) were measured. Radish seeds were germinated at control, 100 mM, 150 mM and 200 mM salt concentrations. Salt stress did not inhibit germination at a high level but negatively affected the vegetative growth of plants. According to the results of the statistical analysis of the data obtained, 150 mM was determined as the threshold value. Then, SA was applied to seeds treated with 150 mM salt concentration at different doses (0.25, 0.50, 0.75, 1.00 mM). SA had a positive effect on germination in saline conditions in general and it was concluded that 0.50 mM SA could be applied for germination percentages in all cultivars. However, 1 mM SA inhibited the germination of big red and little red radish cultivars, causing sudden and severe germination losses (10%, 8%, respectively). The effects of SA on vegetative growth parameters differed by cultivar and it was found to be inhibitory in terms of vegetative growth characteristics of white radish cultivar. On the other hand, 0.50 mM SA in black and big red, 0.75 mM SA in little red cultivar gave promoting results for vegetative growth.

Fikriye Alev Akçay | Ayşe Avcı
In this study, effects of medium components and inoculum size on the protease production by Bacillus sp. EBTA6 that was isolated from a home-made Tarhana sample were investigated. The cell-free supernatant of bacterium cultured on a shaking incubator for 24 h was used to test protease activity as the response. With a total number of 11 factors, 12 different experiments were run and the highest experimental protease activity was measured as 2280.4 U/mL. Results were analyzed statistically by ANOVA and the most efficient factors were detected as yeast extract, dipotassium phosphate, casein, and peptone with a contribution of 93.78, 2.19, 1.96, 1.31%, respectively. For validation of the selected factors, a further experiment was performed by using of yeast extract (9.98 g/L), dipotassium phosphate (1.27 g/L), casein (8.69 g/L), and peptone (9.88 g/L) obtained from the design equation. The experimental response was found as 2411.4 U/mL which was only 5.5% higher than the predicted response showing that the model was applicable.

2020
Lelisa Endalu Tura | Tasisa Temesgen Tolossa
The main purpose of this paper is to review on the effect of irrigation water quality and deficit irrigation on crop yield and water use efficiency. Low quality water for irrigation can impose a major environmental constraint to crop productivity. If salts become excessive, losses in yield will result. To prevent yield loss, salts in the soil must be controlled at a concentration below that which might affect yield. Irrigation application below the full evapotranspiration requirement is termed as deficit irrigation. Deficit irrigation consists of deliberately applying irrigation water in amounts below the plant’s water requirements. Deficit irrigation can be applied at certain periods during the crop’s growing season or throughout its growing season. Yield reductions also occur in a number of crops when subjected to water stress. Yield reductions depend on the crop’s sensitivity to water stress at its various growth stages. In order for deficit irrigation to be an economically viable practice, the revenue lost due to yield reduction should be lower than savings in total cost of production. The goal of deficit irrigation is to increase crop water use efficiency by reducing the amount of water that is applied or by reducing the number of irrigation events. The interaction effects of water quality and DI illustrated that when the two types of stresses; saline and DI were coupled together, a serious reduction occurred on total dry biomass and total yield. The interaction effects of water quality and deficit irrigation illustrated that when the two types of stresses; saline and deficit irrigation were coupled together, a serious reduction occurred on total dry biomass and total yields.

Tarafımızdan yürütülen çalışmalarda in vitro kültürlerde mezankimal kök hücreleri ve endotelyal hücre hatları kullanılarak suyun IC50 değeri tespit edilerek hücreler üzerindeki pozitif ve negatif etki dozları belirlenmektedir. Buradan elde edilen sonuçlara bağlı olarak, gerekli olması durumda tüm organizmadaki etkileri deney hayvanları üzerinde in vivo olarak incelenebilmektedir. Bu amaçla genç wistar sıçanları deney gruplarına (deney ve kontrol) ayrılarak, su ihtiyaçları 3 ila 6 ay süre ile çalışma alanından temin edilen su örnekleri ile karşılanmaktadır. Belirli zaman noktalarında her bir gruptaki deneklerden kan ve idrar numunesi alınarak rutin biyokimya analizleri ile hemogramı analizlenerek değişimler kaydedilmektedir. Ayrıca aylık periyotlarla örneklemdeki denekler sakrifiye edilerek endojen dokuların genel muayenesi yapılarak histolojik ve kimyasal analizler için karaciğer, böbrek ve kalp dokusundan örnekler alınmaktadır. Doku örneklerinin bir kısmı mikrodalga kullanılarak homojenizat haline getirilir ve element içeriğindeki değişimler ICP_OES ile tayin edilmektedir. Diğer kısmı ise %10’luk formaldehitte tespit edildikten sonra dondurarak kesit alma yöntemine göre 5 um’lik ince kesitleri alınarak histopatalojik olarak incelenmektedir. Bu çalışmalar göstermişti ki su analizlerinde kullanılan bilindik yöntemler çok kıymetli olsa da sitotoksik analiz yöntemiyle yapılan su kalitesi çalışması su kalitesinin direkt canlı doku üzerinde etkilerinin gözlenmesi açısından güvenilirlik sağlamaktadır. Sunulan çalışmada, sonuçlarının çarpıcılığı nedeniyle İncesu Havzasından alınan su numuneleri için yürütülen in vitro sitotoksisite çalışmaları örnek olarak verilmiştir. Elde edilen sonuçlar ışığında in vitro sitotoksisite testlerinin rutin su kalitesi analizlerine eklenmesi gerektiği önerilmektedir.

Çetin Kadakal | Nizam Mustafa Nizamoğlu | Tolga Kağan Tepe | Sevda Arısoy | Begüm Tepe | Suat Batu
Thirteen different mostly consumed cheese samples were obtained from different provinces in Turkey and were investigated in terms of contents of ergosterol, patulin and Ochratoxin A (OTA). Ergosterol, patulin and OTA analyses were carried out by using the apparatus of high-performance liquid chromatography (HPLC). Ergosterol contents of samples ranged from 30.27±0.69 to 144.76±9.41 mg/kg. The values of OTA in the samples were ranged from 6.96±0.05 to 41±0.2 µg/kg. Ergosterol was significantly correlated with OTA (r = 0.99, R2 = 0.98). According to this high correlation, ergosterol might be used as a more readily measurable indicator of potential OTA production. No patulin was detected in all samples. Absence of patulin on cheese samples may be explained with unsuitable media for patulin producing.

Adnan Çiçek | Merve Ayyıldız | Didem Doğar
Meat and Milk Institution is implementing red meat sales through grocery chains in order to ensure stability in red meat prices in Turkey. In this study in order to evaluate the effectiveness of this policy from the perspective of consumers, data set obtained from 388 households in Gaziantep city center was used. According to the findings, it has been determined that 53.6% of consumers prefer contracted markets due to the suitability of red meat prices. Initially, all consumers bought red meat from contracted markets, but it was found that 62.11% of them gave up buying red meat from these markets. This situation was found to be quite remarkable and logit model was used to determine the factors affecting the continuity of red meat purchase of households from contracted markets. According to the Logit model results, it was observed that households buying red meat from the contracted markets were affected by the variables that they are care about the price of red meat, income and frequency of shopping at these markets. As a result, it can be stated that this policy implemented by the ESK is aimed at selling red meat to low-income consumers rather than providing price stability and does not have a demand increasing effect.

La agricultura ha progresado ininterrumpidamente, pasando de la utilización de recursos naturales gratuitos al uso creciente de recursos fósiles como fuentes energéticas. Si bien la agricultura depende fundamentalmente de los recursos y servicios del ecosistema, su desarrollo se ha centrado sólo en la producción, sin tomar en cuenta el valor ecológico de las externalidades negativas ni la descapitalización de los recursos que inciden en la sustentabilidad, por lo que la información sobre la evaluación de la sustentabilidad de los diferentes estilos de agricultura es poca o casi nula. En la presente investigación se evaluó la sustentabilidad de los estilos de agricultura (horticultor intensivo, tradicional campesino y horticultor auto sostenible) establecidos en la comuna de Hualqui (Región del Biobío, Chile), mediante los flujos de energía presentes en cada estilo, para medir el impacto que generan sobre el paisaje. Los resultados muestran que el estilo de agricultura horticultor auto sostenible presenta una mayor sustentabilidad en comparación con los estilos tradicional campesino y horticultor intensivo y pueden contribuir a nivel de políticas públicas para reorientar la estrategia de acción y fomentar la sustentabilidad en los distintos estilos de agricultura. ¬¬¬¬ Agriculture has been progressing continuously, from the use of free natural resources to the fossil fuels as energy sources.

Pose, Nélida Nancy | Baeza, María Cecilia | Zamuner, Ester Cristina | Di Gerónimo, Paula | Videla, Cecilia Del Carmen
The dynamic change occurred in the soil due to different uses can be can be estimated by monitoring sensible variables. There is no agreement about the most appropriate phosphorus (P) parameter for this purpose. The aim of this work was to evaluate the usefulness of soil tests for P availability, risk of P loss and P retention capacities (P-Bray1, P-CaCl2, P75, PSI and DPS in order to differentiate changes in soil P content related to soil uses, and to establish the relationship between these techniques. Two soil depths in two sites at the southeast of Buenos Aires province were analyzed. Different soil uses were considered: natural grasslands (PN), forest systems (FO), secondary grassland (PS) and different agricultural sequences (A). All techniques significantly differentiated between management systems; however, these differences were affected by soil depth. There were close correlations between the techniques, but there were dependent of soil use, P-Bray1 to P-CaCl2 (R2 = 0.89), P75 to PSI (R2 = 0.79) and DPSP75 or DPSPSI to P-CaCl2 (R2 = 0.82 and 0.83 respectively). The A systems increased P availability (P-Bray1), decreased P retention capacities (P75 and PSI) and generated an increased risk of P losses (P-CaCl2). The FO and the PS had better P availability with respect to the PN, more P retention capacity and lower risks of P losses by runoff. Based on these results, a given P form could be estimated based on the analytical determination of another P form, but differentially by soil use. | El cambio dinámico en el suelo debido a diferentes usos puede monitorearse mediante el seguimiento de variables sensibles. Para el contenido de fósforo (P), no existe un consenso acerca de la variable de medición más adecuada. En este trabajo se evaluó la utilidad de técnicas que miden disponibilidad, pérdida y capacidad de retención de P (P-Bray1, P-CaCl2, P75, ISP y GSP) para diferenciar cambios en el contenido de P del suelo, relacionados al uso de la tierra, así como la relación entre dichas técnicas. Se analizaron dos profundidades de suelo en dos sitios del sudeste de la provincia de Buenos Aires con diferentes secuencias: agrícolas (A), pastizales nativos (PN), sistemas forestales (FO) y pastizales secundarios (PS). Todas las técnicas pudieron diferenciar entre sistemas de manejo; con diferencias variables según la profundidad del suelo. Se detectaron correlaciones estrechas entre las técnicas, resultando dependientes del uso del suelo, P-Bray1 y P-CaCl2 (R2 = 0.89), P75 e ISP (R2 = 0,79) y GSPP75 o GSPISP con P-CaCl2 (R2 = 0.82 y 0.83 respectivamente). Los sistemas A incrementaron la disponibilidad de P (P-Bray1), disminuyeron la capacidad de retención (P75 e ISP) y generaron mayor riesgo de pérdidas de P (P-CaCl2). El FO y la PS presentaron mejor disponibilidad de P respecto de PN, con mayor capacidad de retención y con menores riesgos de pérdidas por escurrimiento. En base a los resultados, podría estimarse una forma de P en función de la determinación analítica de otra, pero de forma diferencial según el uso del suelo.
