Yusuf Alparslan Argun | Özgür Çakmakcı
Animal wastes are not stored correctly and are used haphazardly without control in agricultural lands. As a result, it causes many irreparable environmental pollution, especially water pollution. These wastes, which are described as diffuse pollution, cause pollution of both underground and surface water resources directly or indirectly and even make them unusable. In this research, waste generation as a result of animal breeding in Karaman province, its districts, neighborhoods and villages and the effects of animal wastes on environmental pollution were evaluated with distributed pollutant load calculations. In the study, the number of 1019277 ovine and 81368 bovine in Karaman in 2022 was used. The total nitrogen (TN) produced annually by the animals has been calculated as 1,723.23 tons/year, and the total phosphorus (TP) amount is determined as 124.23 tons/year. Additionally, for large ruminant animals, the annual total amount of dry manure is 130,305.77 tons, and for small ruminant animals, it is 41,984.27 tons. To prevent environmental pollution, these wastes should be stored in closed areas in compliance with standards, and processes such as composting, drying, and biogas production should be applied. By doing so, not only can environmental pollution be mitigated but also economic value can be obtained. The proper management and utilization of these wastes have high economic potential and can contribute to sustainable development, supporting the country’s economy. In addition, this study is a source for researchers working in the field in calculating the pollution load of animal wastes and is thought to be a guide for decision makers and practitioners.

Sürdürülebilir topraksız tarım için çevre dostu ve yenilenebilir materyallerin önemi her geçen gün artmaktadır. Yeşil ve organik atıklardan elde edilen kompost bu materyallerden biridir. Bu çalışmada elma, üzüm ve domates posalarından elde edilen kompostun topraksız domates yetiştiriciliğinde etkileri araştırılmıştır. Elma, üzüm ve domates atıkları meyve suyu ve salça fabrikalarından temin edilmiştir. Elma, üzüm ve domates atıkları ayrı ayrı kompostlaştırılmıştır. Kompost yapımında ana materyale (2m3) 200 dm3 ahır gübresi, 5 kg kireç ve 5 kg üre ilave edilmiştir. Kompost yapımı 22 hafta sürmüştür. Denemede 9 farklı ortam kullanılmış olup, bunlar; kokopit: perlit (2:1) (Kontrol); domates kompostu: perlit (2:1) (D); elma kompostu: perlit (2:1) (E); üzüm kompostu:perlit (2:1) (Ü); domates: elma: üzüm kompostu: perlit (1:1:1:1) (DEÜ); domates kompostu: kokopit: perlit (1:1:1) (DC); elma kompostu: kokopit: perlit (1:1:1) (EC); üzüm kompostu: kokopit: perlit (1:1:1) (ÜC) ve DEÜ kompostu: kokopit: perlit (1:1:1) (DEÜC). Ortamlar hacim esasına göre belirlenmiştir. Besin solüsyonu çiçeklenmeye kadar 2,0 dS/m ve çiçeklenmeden sonra 2,2 dS/m, pH:5,9 şeklinde uygulanmıştır. En yüksek pazarlanabilir verim elma, domates ve üzüm kompostu + kokopit uygulamasında 286,59 ton/ha olmuştur. Kompost kullanılması pazarlanabilir verimde kontrole göre %39,73 artış sağlanmıştır. Vitamin C kontrolde en yüksek çıkarken, pH ve suda çözünebilir kuru madde miktarı değişmemiştir. Kompost kullanılması domates meyvelerinde çiçek burnu çürüklüğünü azaltmış, yaprak kuru ağırlığını artırmıştır. Sonuç olarak, denemede üzüm ve özellikle elma posasından elde edilen kompostun topraksız tarımda domates yetiştiriciliğinde başarıyla kullanılabildiği ve ticari ortamlardan biri olan kokpite göre daha etkili olduğu anlaşılmıştır.

Drying is the simultaneous transfer of heat and mass, which is defined as the reduction of moisture in food. The aim of the study the drying performances of refractance window drying (95°C), fluidized bed drying (95°C, 2m3/m air velocity), and convective drying (95°C) were examined in the drying of Maraş green pepper (C.annuum). Drying performance was evaluated for effective diffusion coefficient (Deff), activation energy (Ea), Chroma (C) and total color change (ΔE). Drying curves were obtained by recording sample weights in 10-min periods. For the refractance window drying, fluidized bed drying and convective drying the time for the samples to reach 6-7% humidity level according to the wet base was found to be 70, 80 and 110min, and the effective diffusion coefficient was 6.49x10-10, 5.68x10-10 and 4.87x10-10 m2/s the activation energy was 53.54, 54.65 and 55.93kJ/mol, respectively. When the color properties are examined the Chroma value was determined as 18.23, 8.85 and 4.80 and the total color as 15.42, 26.29 and 30.33, respectively. It was seen that the closest value to the fresh product was in the samples dried with a refractance window drying. In the study, it was concluded that the use of a refractance window drying shortened the drying time by 14-36%, increased the effective diffusion coefficient, provided drying with lower activation energy, and better preserved the color quality in the production of dried Maraş green pepper.

The present study, it was aimed to determine the effect of antioxidants added to culture media on blastocyst development rates in in vitro embryo production. The material of the study consisted of oocytes collected from the ovaries taken from the slaughterhouse. Cumulus oocyte complexes (COC) were collected and classified under a stereomicroscope. Oocytes included in the study were subjected to maturation and fertilization stages. Probable zygotes were transferred to the culture (IVC) containing antioxidants (L-ergothionine 100 μM (n: 163), Vitamin E 100 μM (n: 151) Cysteamine 50 μM (n: 154) and were cultured in a tri gas incubator (Hera Cell- 6% O2%, 6%CO2, 88%N). Blastocyst rates and embryo quality were determined on the 6th and 7th days in culture medium. Differences in IVMFC stages were evaluated by chi-square test. 966 oocytes were collected from 162 ovaries collected from the slaughterhouse. It was determined that the number of oocytes per ovary was 5,96, and the number of A and B quality oocytes was 4.26. It was determined that 655 (94.93%) of a total of 690 oocytes undergoing in vitro maturation were mature. The cleavage rates of the groups were 83.44%; 80.79%; 79.87%, and 83.96%, respectively. 140 (21.37%) blastocysts were obtained from 655 oocytes taken into the culture stage and the blastocyst rates in the groups were 33.13%; 8.61%; 7.79%, and 32.62%, respectively. As a result of the study, it was determined that the rates of blastocysts in the L-ergothioneine added the group was similar to the control group, but the blastocyst rates decreased significantly in the cysteamine and Vitamin E added groups. It was thought that this decrease might have been affected by the dose of antioxidants or the adequacy of oocyte development

In the background of improving Water Productivity, there is concern in deficit irrigation, which delivers a means of decreasing water depletion while reducing opposing effects on yield. A field experiment was conducted at Haramaya, Ethiopia during 2020 off-season. The objective was determining effects of irrigation levels and mulch types on yield and Water Productivity of Onion. The experimental design was a split plot in RCBD with three replications. The deficit irrigation levels 100%, 85%, 70% and 55% ETc used with the three mulch types no mulch, straw and white plastic mulch were used. The results revealed that the maximum yield of 38.43 ton ha-1 was recorded from 100% ETc with plastic mulch; whereas the minimum yield of 16.36 ton ha-1 was recorded from 55% ETc with no mulch. Higher Crop Water Productivity of about 9.04 kg ha-1mm-1 was obtained from 85% ETc with plastic mulch. With 85% ETc and plastic mulch the water saved, yield reduction and Crop Water Productivity were 113.13 mm, 9.57% and 9.04 kg ha-1 mm-1 respectively. In view of water saved and maximum yield, irrigation water application at 85% irrigation application levels and plastic mulch could be concerned. The current study recommends that, in water limited area, farming community can accept deficit irrigation level with 85% ETc under plastic mulch.

We, here, aimed to determine the presence of Anguillicola crassus, a swim bladder parasite, in 89 (male: 45, female: 44) dead European eel specimens obtained seasonally between 2020-2021 from a regional fisherman, who has fished with fyke net in the locality Tuzla of Izmir Bay, Eastern Aegean Sea. Out of 21 male European eels caught in winter, only one specimen (TL: 48.5 cm and TW: 247.12 g) had 23 swim bladder parasites (adult nematodes: 15, larvae: 8) and similarly, only one parasite was found in one specimen (TL: 37.5 cm and TW: 88.47 g) of 8 eels caught in spring. No parasite was found in the female eels. At the examinations, it was determined that all adult Anguillicola crassus specimens were females and the minimum-maximum and average length values in adult and larval parasites were, respectively, 1.5-2.5 cm (1.99 ± 0.31) and 0.7-1.3 cm (1.025 ± 2.40). Consequently, the species A. crassus, a swim bladder parasite, was found in European eels from the locality Çamalti Tuzla in two seasons (winter and spring) and this parasitic nematode were only in male eels. This study is a first and remarkable one having evidential value, which shows the presence of the species A. crassus among the eel population in the locality Çamalti Tuzla of Izmir Bay. Besides, it is a population that should be monitored due to the status of Anguilla anguilla on the IUCN red list.

The experiment was conducted in one of the unheated plastic polyethylene (PE) greenhouses of Ege University- Bayındır Vocational Training School -TURKİYE during the winter-early spring of 2019-2020. The goal of the trial was to evaluate the effects of liquid vermicompost (LVC) on Iceberg (Head salad) and Lolo rosso (Lactuca sativa) lettuce in a floating hydroponic system. Two types of growing pools were used as the growing media, one was made of galvanized steel and the other plastic polyethylene. Both pools were covered with a polyethylene at a height of 1 meter from the ground. Lettuce seedlings were transplanted into pools filled with water and a week later Liquid Vermicompost (LVC) and Hoagland Nutrient Solution (HNS) were added to the growing media according to the treatments. The trial was set up in a Randomized Block Design (RBD) with 3 treatments and 3 replications in both of the lettuce varieties. 1. Application: HNS +LVC; 2. Application (HNS); 3. Application (LVC). Lettuce leaves were harvested 84 days after the LVC and HNS applications and prepared for analysis. In this research, in order to determine the impact of liquid vermicompost on Iceberg and Lolo rosso lettuce varieties total yield, marketable yield, the number of leaves discarded, root length and root weights were determined after harvested plants. In both of the lettuce varieties, results indicated that the highest marketable yields were obtained in the first treatment (HNS+LVC). The highest root length and root weight were also determined in the first treatment. It can be concluded that adding liquid vermicompost (100 ml / 100 L water ratio) to the growing solutions of Iceberg (Head lettuce) and Lolo rosso (Lactuca sativa) lettuce varieties, high performances can be obtained.
