N150-K100 kombinasyonu Akdeniz ekolojik koşullarındaki İzmir’de, tatlı sorgumun etanol verimini yükselten en iyi gübre seviyesi olduğu ortaya çıkmıştır.

This study was conducted to determine the annual energy use and related greenhouse gas (GHG) emissions of individual deep well irrigation enterprise. That study was conducted at deep well farm belonging to one farmer with volunteer preforming farming activities in Konya-Meram-Çarıklar location for the growing season of 2021. In that regard, the activities using alfalfa and dry bean production, and total production inputs with their amounts as well as crop yields were determined separately. By considering unit energy equivalent values and GHG emission factors of each input, annual energy consumption and GHG emission values were calculated. Similarly, by examining energy content and crop yield in accordance of crop production unit (kg), annual produced energy amount was calculated. The evaluation was made using energy used and energy produced as well as GHG emission values indicators at individual deep well irrigation farm. According to the results obtained, annual energy use and energy production were calculated 253035 mega-joule (MJ), and 487960 MJ, respectively for individual well irrigation farm. The electricity used during the irrigation processes resulted around 71% of annual energy consumption. The annual GHG emission amount as an equivalent to the carbon dioxide (CO2eqv) for research farm with GWI was determined as 18575 kg (18575 kgCO2eqv year-1). Almost 52% of annual GHG emission was resulted from electricity used in irrigation.

Difficulties in adventitious root formation in blackberry (Rubus fructicosus L.) cuttings create a disadvantage for producers. The aim of this study is to investigate the effect of different growth regulator applications on the rooting ability of blackberry hardwood cuttings in order to avoid this problem. The experiment was carried out in the polycarbonate greenhouse of Tokat Gaziosmanpaşa University Agricultural Research and Application Center In the experiment, in addition to the control (pure water) group, Indole-3-Butyric Acid (3000 ppm IBA) and different doses of paclobultrazole (500 ppm PBZ1, 1000 ppm PBZ2, 1500 ppm PBZ3) were applied to hardwood cuttings separately and in combination. After the application, the cuttings were planted in perlite medium and left to root for 90 days. At the end of this period, in the cuttings removed; rooting rate, callus formation rate, root number, root length and root diameter parameters were examined. As a result of the study, the highest rooting rate was obtained from the IBA applied cuttings (%42.22), followed by the PBZ1 applied cuttings closest (%33.33). In addition, it was determined that PBZ applications had positive effects on root diameter compared to the control group. The results obtained are important in terms of contributing to the literature and benefiting the enterprises

In this study, it was aimed to reveal some viruses that are a problem in tomato production areas in the Ereğli district of Konya, where tomato production is common. For this reason, in the 2019 production season, leaf samples were taken from 160 tomato plants showing symptoms similar to virus disease symptoms such as mosaic, deformations, yellowing, blight on the leaves and stunted plants. Possible infections of Cucumber mosaic virus (CMV), Tomato spotted-wilt virus (TSWV) and Tomato mosaic virus (ToMV) on these leaves were tested by serological-based DAS-ELISA (Double Antibody Sandwich- Enzyme Linked Immuno Sorbent Assay) method. According to DAS-ELISA results, it was determined that 66.25% of the samples were infected with at least one of these three viruses. In addition, TSWV was detected as the most common virus with a 48.75% relative infection rate in the samples, followed by ToMV (28.75%) and CMV (26.25%). Mixed infections of the viruses were also detected in the leaf samples tested. CMV + TSWV double infection was detected in 22 samples, ToMV + TSWV double infection was detected in 14 samples, and CMV + ToMV + TSWV triple infection was detected in 12 plant samples.

Leonardite and compost are used as soil conditioner materials. Gyttja is a material which contains 30-40% lime and 40-50% organic matter with a reserve of approximately 4.8 billion tons in Afşin-Elbistan Thermal Power Plant basin. These materials are used in the production of organomineral (OMG) fertilizers. Zinc (Zn) is one of the micronutrients that plants need. Available Zn deficiency is observed in approximately 49% of Turkish soils. The aim of this study was to determine the Zn adsorption properties of gyttja, leonardite and compost used in OMG fertilizer production. The study was conducted under laboratory conditions. In order to determine the optimum adsorption conditions, the effect of pH, particle size, temperature, shaking time and solution concentration were determined. Then, adsorption properties were determined using linear Langmuir isotherm under optimum conditions. According to Langmuir isotherm, the maximum sorption capacity (qmax) was found to be 14.10 mgg-1 for gyttja, 13.74 mgg-1 for leonardite and 15.67 mgg-1 for compost. In conclusion, Zn sorption values of gyttja, leonardite and compost were consistent with Langmuir and Freunlich isotherms. The maximum sorption capacity (qmax) of these materials is very close to each other. When these data are taken into consideration, it is seen that 1 kg of organic material can sorbed about 15 g Zn. It is useful to take these basic data into account in OMG fertilizer production and sustainable Zn fertilization.

In this study, dog traffic in the animal shelter of Sivas province was investigated both quantitatively on the basis of years and the reasons for abandonment, as well as the attitudes and behaviors of the animal owners. In the study, besides the dog traffic records of the stray animal rehabilitation center operated by Sivas Municipality, the survey data made with the owners who left their dogs there were analyzed. According to the four-year records (2019-2022), the average number of dogs staying in the Sivas Municipality Animal Shelter is 1058, while the average number of dogs collected from the street per month is 50.7, the average number of spayed female and male dogs per month is 17.33 and 33.44, respectively. The average number of adopted female and male dogs was 2.8 and 4.3 respectively and, dog deaths per month in the shelter was 21.9. Every month, an average of 15 dogs were released back to the point where they were taken after the spayed and treated at the animal shelter. In addition, a face-to-face survey was conducted with a total of 50 people who left their dogs in the shelter and 15 questions were asked to the participants, including the reasons for adopting/abandonment and form of care-feeding. As a result, it can be said that it would be beneficial to deal with the process in many different provinces with more detailed studies in terms of the ever-increasing number of dog acquisitions in the society and the prevention of their abandonment.

This study aimed to investigate the body weight and some body measurements in Central Anatolian Merino sheep regarding ages and to carry out a comparative analysis between them. The study included a total of 60 animals aged 2, 3 and 4 years. The sheep were fed daily with hay, vetch, alfalfa and limited amount of concentrated feed (400 g head-1) until the pasture period, and pasture grass and mixed grass-clover hay during the pasture period. The live weights of the sheep of different ages in the farms were measured with a digital scale, and some body size were measured using a measuring tape and a measuring stick. When the live weight and chest circumference values of the 4-year-old sheep were compared with the data obtained in the other age groups (2 and 3 years old), and it was statistically significant, chest width and rump height values were found to be similar to those in the 3-age group. There were significant correlations between live weight and chest circumference, between withers height and rump height and significant correlations between live weight and chest width, body length with rump height, chest width with chest depth. In addition, significant correlations were found between live weight and chest depth, and between withers height, body length, and chest depth. Present findings revealed that the Central Anatolian Merino sheep can be beneficial in the development of meat-type sheep breeding.
