Mapping the Dispersion Pollution Load of Animal Waste and Investigating its Environmental Effects: The Case of Karaman النص الكامل
2023
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.

Sarjit Pandey | Dharma Raj Katuwal | Rashmi Aryal
The maize weevil (Sitophilus zeamais Motschulsky) causes significant quantitative and qualitative losses during storage. To identify resistant varieties of maize against this pest, an experiment was conducted in a Completely Randomized Design (CRD) with 11 varieties in free and no-choice conditions. The study measured weight loss, mean bored grain, debris, and weevil numbers at 30, 60, and 90 days. The findings showed that BG13Y-POP, Manakamana-7, and RML-19/RML-6 were the most resistant varieties, with weight loss percentages of 1.99%, 1.47%, and 1.74%, respectively, and final weevil numbers of 104, 72, and 73. Ganesh-2 and ZM-401 were the most susceptible varieties, with weight losses of 7.34% and 6.05%, respectively. The maximum debris weight was found in RML-761/RL-105 (1.98 g), while the minimum was found in Manakamana-7 (0.26 g). The highest number of bored grains was observed in Ganesh-2 (81), while the lowest number was observed in Rampur-4 (51). Similarly, ZM-401 (158) and Ganesh-2 (165) exhibited the highest weevil population, while the lowest count was found in Rampur-4 (72). Overall, using resistant varieties, such as Manakamana-7, BG13Y-POP, and RML-19/RML-6, can be an effective approach for reducing post-harvest losses from weevil infestation.

Mine Sungur | İbrahim Bakır
Throughout history, there has been a reciprocal relationship between humans and space. Even though there are numerous spaces covered by this ongoing relationship process, it has integrated and gained value with educational venues. Mainly because they closely monitor social, cultural, technological, and economic developments and pass on knowledge to future generations, educational spaces play a crucial role in the development of individuals as well as society. It is feasible to conclude from research on educational spaces that the physical environment has a major positive or negative impact on education. To solve the issue that the current Faculty of Fine Arts at Selçuk University could not sufficiently respond to user needs physically, it was decided to construct a new Faculty of Fine Arts building. The primary goal of the study is to design the building using user-oriented techniques that promote social interaction and showcase artistic identity throughout the design phase. A qualitative research approach, based on inspection and observations, was used in the study to gather data, documents, and reports on the topic and to ensure that the architectural programming stages advanced correctly and received ongoing feedback. Studies have confirmed the results, which show that artistic education in structures that provide users with distinct experiences is different from that provided in faculty buildings with a type plan scheme. The process, which involves collaboration between stakeholders from various disciplines and necessitates coordination, is also maintained in a coordinated fashion as a consequence of the study. Because of this, it is believed that buildings with comparable features can offer direction by offering a set of data that may also be reliable for design procedures that are prearranged.

Ahmet Coşkun | Huzur Deveci | Fatih Konukcu
Bu çalışmanın amacı, Trakya Bölgesi’nde iklim değişikliğinin buğday bitkisinin verimine etkisini modellemektir. Bu amaçla, çiftçi tarlasından alınan 2020-2021 dönemi buğday verim değeri, aynı yıla ait iklim verileri kullanılarak LINTUL model ile hesaplanan verim değeri ile karşılaştırılarak kalibre edilmiş ve daha sonra HadGEM2-ES ve MPI-ESM-MR küresel iklim modellerinin RCP4.5 ve RCP8.5 senaryolarından elde edilen iklim verileri ile 2031-2040, 2041-2050, 2051-2060, 2061-2070 ve 2071-2080 dönemleri için verim değerleri tahmin edilmiştir. Ekim ve hasat tarihleri değiştirilmeden iki şekilde verim tahmini yapılmıştır: Birincisinde, ortalama en düşük ve en yüksek sıcaklık, solar radyasyon ve yağış değişimi dikkate alınarak verim hesaplaması yapılmıştır. İkincisinde ise solar radyasyon değerleri 2004-2021 dönemi için sabit tutulurken, ortalama en düşük ve en yüksek sıcaklık ve yağış değişimleri hesaba katılmıştır. Birinci yaklaşımda, HadGEM2-ES modelinin RCP4.5 ve RCP8.5 senaryoları için tahmin edilen verim değişimleri sırasıyla %1,5-%7,5 ve -%7,5-%7,5 arasında hesaplanırken, MPI-ESM-MR modeli için yine aynı sırayla %9,0-%13,4 ve %3,0-%16,4 arasında simüle edilmiştir. İkinci yaklaşımda, HadGEM2-ES modelinin RCP4.5 ve RCP8.5 senaryoları için tahmin edilen verim değişimleri sırasıyla %4,5-%9,0 ve -%7,5-%7,5 arasında hesaplanırken, MPI-ESM-MR modeli için yine aynı sırayla %10,4-%13,4 ve %4,5-%19,5 arasında tahmin edilmiştir. Verim tahminlerinde sıcaklık ve yağışla birlikte solar radyasyonun etkisinin de mutlaka göz önünde bulundurulması gerektiği; Türkiye’nin diğer bölgelerinin aksine iklim değişimi ile verimin genelde artış yönünde olacağı tahmin edildiğinden gıda güvencesi için Trakya Bölgesi tarım arazilerinin değişimine izin verilmemesi gerektiği sonucuna varılmıştır.

Manda yetiştiriciliğinin avantajları ve mandadan elde edilen ürünlerin insan sağlığındaki üstünlüklerine rağmen, dünyada manda popülasyonunun azalan bir trendle düşük olduğu ve nesli tehlikede olan türler arasında olduğu belirtilmektedir. Dünyada manda yetiştiriciliği yapılan ülkeler arasında manda sayısında en hızlı azalışın gerçekleştiği ülke konumunda olan Türkiye’de, Samsun ili manda popülasyonunda geçmişten günümüze birinci sırada yer almaktadır. Bu çalışmanın amacı Türkiye ve Samsun ilinde 2023-2030 yılları arasında manda popülasyonunun Çift Üstel Düzleştirme ve Holt-Winters yöntemleri ile geleceğe yönelik tahminlerini gerçekleştirmektir. Çalışmada Türkiye manda popülasyon serisi için 1929-2022 yılları arası, Samsun ili manda popülasyon serisi için ise 1991-2022 yılları arası verileri kullanılmıştır. Araştırmada serilerin durağan olmadığı belirlenmiş olup, birinci farkı alındıktan sonra seriler durağanlaştırılmıştır. Manda popülasyon tahmini için Holt-Winters modelinin veri setine en uygun model olduğuna karar verilmiştir. Bu modele göre 2030 yılında 2022 yılına göre Türkiye manda popülasyonunun %7,29 oranında artış yaşanacağı, Samsun ili manda popülasyonunun ise gelecek sekiz yıl içinde stabil kalacağı belirlenmiştir. Çalışmada, yakın gelecekte Türkiye'de manda popülasyonunun yok olma tehlikesi ile karşı karşıya kalacağı belirlenmiştir. Türkiye’de manda varlığının sürdürülebilirliği için hükümet tarafından uzun vadeli ve etkili politika araçları uygulamaya konularak verilen desteklemeler artırılmalı ve tüketicilerin de manda sütü ve etinin faydaları hakkında bilinçlendirilmesi sağlanarak talep artışı sağlanmalıdır.

A field experiment was conducted at the Agronomy farm of Nepal Agricultural Research Council (NARC), Khumaltar, Lalitpur to evaluate the effect of sowing dates and seed rates on yield and yield attributes of wheat. The experiment was laid in a split-plot design with three replications treated with 4 sowing dates as the main plot factor (12th Nov, 27th Nov, 12th Dec, and 27th Dec) and 4 seed rates as subplot factor (100 kg ha-1, 120 kg ha-1, 140 kg ha-1 and 160 kg ha-1). Results revealed that the leaf area index was significantly affected by sowing dates and was comparatively superior in 2nd sowing date (27th Nov) wheat. Similarly, in the case of seed rates, the leaf area index was influenced significantly and was recorded to be increasing with an increase in seed rates. Phenological parameters like days to 50% heading, flowering, and maturity were observed maximum (116, 123, and 179 days, respectively) in early sown wheat and reduced with the subsequent delay in sowing. Maximum values of yield and yield attributes like effective tillers per meter square (635.6), spike length (9.56 cm), grains per spike (41.49), grain yield (7.59 Mt ha-1), and straw yield (9.58 Mt ha-1) were observed in the wheat sown in 2nd date (on 27th Nov) which differed significantly to wheat sown on other dates. Seed rates had no significant influence on grain yield and yield attributes. Thousand-grain weight was found maximum (46.26 g) in early sown wheat (on 12th Nov sown wheat, reduced with the subsequent delay in sowing, and the harvest index was observed as maximum (0.51) under December 27 sown wheat. Though the yield and its attributes were not influenced significantly by seed rate, the maximum yield (6.18 Mt ha-1) was observed in wheat sown at the rate of 120 kg ha-1. Considering seed yield and its parameters, 2nd date of sowing wheat (27th Nov) and seed rate of 100 kg ha-1 could be the best option to uplift the productivity of wheat in rainfed lowland conditions of Lalitpur, Nepal.

Este estudio estima el tiempo de vaciado del estómago de la cachama blanca (Piaractus brachypomus) en el día de comienzo regular de alimentación posterior a un periodo de ayuno. Para el efecto, se recolectaron muestras de contenido estomacal en periodos de dos horas después del suministro de alimento (9:30 y 15:30 h) hasta el primer indicio de vaciado. Se utilizaron cachamas con un peso de 360 ± 12 g dispuestas en cuatro tratamientos: (1) T1 = alimentación a saciedad durante 5 días y ayuno de 2 días, (2) T2 = alimentación a saciedad durante 6 días y ayuno de 1 día, (3) T3 = alimentación a saciedad durante 7 días, y (4) TC = alimentación siguiendo las tablas recomendadas por el fabricante del alimento. El análisis de datos se realizó mediante ANOVA de medidas repetidas, empleando como factores el tratamiento y el tiempo de vaciado, siendo cada repetición la unidad experimental. Las cachamas del tratamiento T1 presentaron mayor cantidad de alimento en el estómago en los muestreos posteriores al suministro de la primera y segunda ración. A diferencia del tratamiento T1, en los demás las cachamas vaciaron su contenido en el estómago en el periodo comprendido entre la primera y la segunda ración de alimentación y en el periodo posterior a la segunda ración. Por tanto, cuando el contenido estomacal fue mayor, debido a un mayor consumo de alimento en la ración, como en el caso del tratamiento (T1), el tiempo necesario para vaciar el estómago de las cachamas se incrementó. | The study measured the time necessary to complete emptying of the stomach of white Cachama (Piaractus brachypomus) starting on the day regular feeding subsequent to a starvation period. Samples were collected from stomach contents in periods of 2 hours after feeding (9:30 y 15:30 h) until the first sign of emptying. The cachama weighing was 360 ± 12 g; designing four treatments: (1) T1 = feed to satiation for 5 days and starvation for two days, (2) T2 = feed to satiation for 6 days and starvation for one day, (3) T3 = feed to satiation for 7 days, and (4) TC = restricted feeding table recommended by the manufacturer, 7 days a week. Data analysis was performed using repeated measures ANOVA, using as factors the treatment and emptying time, with each repetition as the experimental unit. Unlike the T5 treatment, in other cachama emptied its contents into the stomach from the time period between the first and the second ration of food and in the period after the second ration. Therefore, when the stomach content was higher due to a higher feed intake in the diet, as in the case of treatment (T5), the time required to empty the stomach of cachama increased.

This research was carried out to determine the pollination abilities of Domat, Gemlik and Sarı Ulak olive cultivars. Pollen viability rate, germination rate and amount of pollen production were examined during the periods when 25%, 50% and 75% of the flowers were opened. According to the results obtained from three years’ experimental study, the highest percentages of pollen viability were found in Gemlik (81.51%) and Domat (81.50%), whereas Sarı Ulak cultivar (77.41%) showed the lowest viability. In pollen germination percentages, the highest values on the basis of cultivars were determined 59.85% (Domat), 59.74% (Gemlik) and 52.12% (Sarı Ulak). The highest amount of pollen production in a flower was found in the Sarı Ulak cultivar (329,046) while it was followed by Domat (319,693) and Gemlik (306,385). Despite the high pollen production in Sarı Ulak cultivar, the pollen viability and germination rates were found to be low. In Gemlik and Domat cultivars, all values were obtained relatively near. In addition, it had been noted that the values related to pollen viability, germination and production amount were higher during 50% and 75% flowering periods than 25%.

In this work, two methods based on microwave-assisted extraction techniques for the extraction of both anthocyanins and total phenolic compounds from açai have been developed. For that, a full factorial design (Box-Behnken design) has been used to optimize the following four variables: solvent composition (25–75% methanol in water), temperature (50–100 °C), pH (2–7), and sample/solvent ratio (0.5 g: 10 mL–0.5 g: 20 mL). The anthocyanins and total phenolic compounds content have been determined by ultra high-pressure liquid chromatography and Folin-Ciocalteu method, respectively. The optimum conditions for the extraction of anthocyanins were 38% MeOH in water, 99.63 °C, pH 3.00, at 0.5 g: 10 mL of ratio, while for the extraction of total phenolic compounds they were 74.16% MeOH in water, 99.14 °C, pH 5.46, at 0.5 g: 20 mL of ratio. Both methods have shown a high repeatability and intermediate precision with a relative standard deviation lower than 5%. Furthermore, an extraction kinetics study was carried out using extraction periods ranging from 2 min until 25 min. The optimized methods have been applied to açai-containing real samples. The results with such real samples have confirmed that both methods are suitable for a rapid and reliable extraction of anthocyanins and total phenolic compounds.

This study investigated how profitable and technically effective rice farming was in Quan’ Pan Local Government Area of Plateau State, Nigeria. Using a multistage sample method, 120 respondents were drawn. The study’s findings proved that the farmers were 40 years old on average. The men were higher in numbers constituting 81.0% of the study population. 83% of the people were married and a greater number (81%) of them had at least some form of formal education with a typical household size of 9 persons. Findings from the study also showed that the farmers owned an average of 2.0 hectares of farmland and had acquired an average farming experience of 12 years. For the most of them (78.0%), farming was their primary occupation. The result also demonstrated that 78.0% never accessed credit or bank loans for farming as majority (63%) of the respondents acquired their farmlands through inheritance. The entire cost (total cost) of farming operation/ha incurred by the farmers was 139733 while the average output obtained per hectare was 699kg at a prevailing market/selling price of 285/kg. The total revenue (TR) measured in naira value of 199, 215 was realized. Gross margin (GM) and net farm income (NFI) stood at 70932 and 59482 respectively. The return on investment (ROI) was 0.42 meaning that for every naira spent on rice production, a profit of 0.42 is made. Age, educational level, farm size, farming experience and extension contact all had positive direct relationship with net income from rice production at 1%. The rice growers’ mean technical efficiency score was 0.659. Major constraints to rice production were high fertilizer prices (72%), inadequate capital (53%), lack of improved seeds (47%). The research suggests that government should subsidize farming inputs like recommended fertilizer and herbicides so as to reduce the over bearing cost burden of these inputs on farmers. Financial institutions should make credit facilities available and affordable to the farmers.

Bu araştırma, tarla koşullarında saksılarda yetiştirilen dört yaşlı “Gemlik” çeşidi zeytin fidanları üzerinde yapılmıştır. Araştırmada; farklı sulama uygulamalarında morfolojik ve fizyolojik parametreler göz önüne alınarak zeytin fidanlarının kuraklık stresine karşı tepkileri incelenmiştir. Araştırma, 2021 yılında, Aydın Adnan Menderes Üniversitesi Ziraat Fakültesine bağlı Araştırma ve Uygulama Çiftliğinde gerçekleştirilmiştir. Deneme tesadüf parseli deneme desenine göre 3 tekerrürlü olarak kurulmuştur. Sulama konuları, bitki su tüketiminin %20 (I20) %40 (I40) %60 (I60), %80 (I80), %100 (I100) ‘ü kadar su uygulanması şeklinde oluşturulmuştur. Çalışma sonucunda; sulama sezonu boyunca konulara uygulanan sulama suyu miktarları 16.32-81.57 L saksı-1 ve buna karşılık elde edilen bitki su tüketimi değerleri ise 19.49-85.08 L saksı-1 arasında değişmiştir. Konulara göre bitki boyunun 3.50 cm ile 11.00 cm, sürgün uzunluğunun 0.14 cm ile 12.4 cm, gövde çapının 0.70 mm ile 2.11 mm, sürgün çapının 0.53 mm ile 1.84 mm arasında değiştiği saptanmıştır. Konulara göre elde edilen yaprak oransal su içeriği değerleri %52.61 ile %71.68, stoma iletkenliği değerleri 260.29 mmol m-2 s-1 ile 535.80 mmol m-2 s-1, klorofil miktarı değerleri 78.00 ile 82.76, yaprak sıcaklığı ve hava sıcaklığı farkı ise 1.93°C ile 5.31°C arasında değiştiği belirlenmiştir. Sonuç olarak, Gemlik çeşidi zeytinin topraktaki nem eksiğine duyarlı bir bitki olduğu, morfolojik ve fizyolojik parametrelerin yetişme mevsimi boyunca sulama suyuna bağlı olarak değiştiği, bu parametrelere ilişkin elde edilen bulgular göz önüne alındığında 4 günde bir eksilen nemin %60’ının (I60) uygulanması önerilebilir.
