In dairy cattle, the dry period cation-anion balance is a critical factor influencing the animal's health and productivity. The cation-anion balance of a ration is contingent upon the anionic and cationic ions present and may assume either a negative or positive value. During the dry period, the optimal cation-anion balance is negative. The administration of anionic salts or anionic ration during this period has been demonstrated to mitigate the risk of milk fever and prevent the development of numerous metabolic disorders. Furthermore, the administration of anionic substances during this period has been demonstrated to influence milk yield, fertility and milk fat. An excessive cation ratio in the ration can cause metabolic problems, including metabolic acidosis, milk fever, and metabolic alkalosis, which is characterised by a decrease in pH and the presence of urine. Therefore, according to the studies, it is recommended that the diet be prepared in a way that the cation-anion balance is negative in the dry period (between -100 to -200 mEq/kg DM).

Soil pH, governed by the relative concentrations of hydrogen () and hydroxyl () ions, is a key factor affecting the chemical, physical, and biological properties of soils. Most soils in Türkiye are alkaline due to calcareous parent material and climatic influences, which restricts the availability of essential nutrients to plants. Sulphur applications are widely employed to reduce soil pH and increase nutrient bioavailability. The use of Sulphur for the amelioration of alkaline soils will continue to be a crucial strategy for enhancing agricultural sustainability in the future. This study investigates the effects of different Sulphur sources on the pH of sandy and clay-loam texture soils. This study investigates the effects of different Sulphur sources on the pH of sandy and clay loam textured soils. The soil samples used in the research were taken from Pınarbaşı and Melikgazi districts of Kayseri province, and soil samples were taken from both regions from a depth of 30 cm and from 20 randomly determined different points. Sulphur applications were applied at rates of (0, 0.02, 0.04 g 100 g-1) (X: powdered Sulphur ) and (0, 0.044, 0.088 g 100 g-1) (Y: granular Sulphur ) based on weight for clay-loam and sandy textured soils, respectively. Samples taken on days 0, 15, 30, 60, 90, 180, and 360 post-applications showed that the impact of Sulphur applications on soil pH change was significant across all treatments (p<0.01). The lowest pH measurement, 6.92, was observed in sandy textured soils with an application from granular Sulphur at 0.088 g 100 g-1. The pH change in clay-loam textured soils was found to range from 8.13 to 7.79, and in sandy textured soils from 7.69 to 6.92. These changes suggest that the acidifying effect of Sulphur oxidation on soil pH varies depending on the soil’s buffering capacity, particle size ratio, application rate, and incubation day. Consequently, the granular Sulphur was found to be more effective compared to the control and powdered Sulphur , and an application rate of 0.088 g 100 g-1 might be effective for both clay-loam and sandy soils. However, due to its lack of economic feasibility, 0.044 g dose or the doses from powdered Sulphur might be more appropriate.

Bu çalışmanın amacı sulamalı buğday üretiminde, üretim girdilerinden kaynaklanan toplam sera gazı (GHG) emisyonlarının azaltılması da dahil olmak üzere, sulama yönetimi yoluyla buğday üretiminde enerji verimliliğini artırma ve çevresel etkiyi azaltma potansiyelini değerlendirmektir. Bu kapsamda gerekli olan üretim girdileri ve ürün verimine ilişkin veriler, 2018-2020 döneminde, Konya’da buğdayda tamamlayıcı sulama üzerine yürütülen tarla denemesinden elde edilmiştir. Bu bağlamda beş farklı sulama rejimi dikkate alınmış olup, bunlar: TTS, buğdayın üç kritik gelişme döneminde, 0-90 cm toprak katmanında eksilen nem miktarı kadar sulama; KTS-1, buğdayın üç kritik gelişme döneminde 90’ar mm su ile sulama; KTS-2, buğdayın üç kritik gelişme döneminde 70’er mm su ile sulama; KTS-3, buğdayın üç kritik gelişme döneminde 50’şer mm su ile sulama ve Y, yağışa dayalı konudur. Çalışmadan elde edilen sonuçlara göre, en yüksek dane verimi (7918 kg ha- 1) ve enerji çıktısı (285857 MJ ha-1) TTS uygulamasında elde edilirken, en iyi enerji üretkenliği (0,935 kg MJ-1) ile enerji verimliliği oranı (12,46) ve en düşük çevre kirliliği (2272 kgCO2 eşd ha-1) KTS-3 rejimi altında gerçekleşmiştir. Çalışma kapsamındaki enerji verimliliği ve çevresel kirlilik analizi önemli bulgulara yol açmıştır. Konya gibi tarım arazisi çok, su kaynakları kısıtlı olan bölgelerde, birim alandan (1 ha) yüksek verimin elde edildiği tam sulama (TTS) yerine, aynı ürün miktarının KTS-2 altında 1,04 ha ve KTS-3 rejimi altında ise 1,09 ha’dan üretilebileceği görülmüştür. Bu yolla, ürün miktarında bir azalış olmadan, sulama suyunda %32,4 ile %49 arasında bir tasarruf sağlanırken, sera gazı emisyonu ise %10,3 ile %15,6 arasında azaltılabilecektir.

Molecular approaches used to identify bacterial species use 16S rRNA and MLST to determine the genetic linkage of bacteria; MLST characterizes clonal linkages by examining differences in various gene loci. MLVA determines the genetic relationships of bacterial strains and biovar-level differences and assesses the copy number of repeated DNA sequences. Sequencing provides genetic data by identifying DNA sequences; Sanger sequencing is the basis for next-generation approaches. CRISPR modifies the genetic code and can correct mutations or control genes using Cas9. These methods are important for identifying bacterial species and annotating genomic information. The methods used for this purpose are brought together in this study. The explanation and detailed description of the methods examined will contribute to their use in the field of microbiology.

Bu çalışma 2021 yılında Tokat Gaziosmanpaşa Üniversitesi bünyesindeki tam otomasyonlu ısıtmalı bir serada yürütülmüştür. Bu çalışmanın amacı, farklı dozlarda mikoriza ve organik gübre uygulamalarının biber fidelerinin gelişimi üzerindeki etkisini incelemektir. Çalışmada Bulut F1 biber çeşidi kullanılmıştır. Araştırma, tesadüf parselleri deneme desenine uygun olarak 3 tekrarlı olarak gerçekleştirilmiştir. Çalışmada, biber fidesi yetiştiriciliği için torf-perlit karışımına mikorizalı ve mikorizasız farklı dozlarda besin solüsyonu ve vermikompost uygulanmıştır. Fideler bir buçuk ayda sökümü yapılmıştır. Bu araştırmada, fide boyu, hipokotil uzunluğu, gövde çapı, yaprak sayısı, yaprak yaş ağırlığı, yaprak kuru ağırlığı, kök yaş ağırlığı ve kök kuru ağırlığı özellikleri incelenmiştir. Çalışma bugularına göre, gövde çapı üzerinde vermikompost+mikoriza+EC uygulamalarının daha iyi sonuç vermiştir. Vermikompost dozları arttıkça fide boyu ve hipokotil uzunluğunda bir artış olduğu ancak vermikompost uygulamalarının etkisinin olmadığı görülmektedir. Genel olarak tüm uygulamalara bakıldığı zaman vermikompost uygulamalarına göre EC ve EC+mikoriza uygulamalarının etkisinin daha fazla olduğu görülmektedir.

Agricultural land cover has changed over time, and monitoring these changes has become an effective tool in development processes by linking them to ecological and socio-economic issues. In this context, the main hypothesis of the study is that “determining land use changes spatially and temporally using CORINE Land Cover data is crucial in development-oriented planning processes.” The study analyzes changes in agricultural land use based on CORINE land cover classes between 1990 and 2018 in the districts of Saray, Şarköy, and Hayrabolu in Tekirdağ Province, which have low levels of socio-economic development. The research aims to answer the following questions: during which periods did significant changes occur in agricultural areas in Saray, Şarköy, and Hayrabolu? What are the total rates of increase or decrease in these areas? Into what types of land have agricultural are+as significantly transformed? The methodology was developed using Geographic Information Systems (GIS)-based maps, graphs, and tables. The findings reveal the spatial and temporal dimensions of changes in agricultural land use and land cover between 1990 and 2018. The data obtained are anticipated to provide a concrete foundation for developing rural development policies and ensuring the sustainable use of natural resources.

This study aimed to evaluate the effects of soybean hay supplementation on growth performance, feed intake, and nutrient utilization in local sheep fed grass hay as a basal diet. Twenty-five yearling intact male local sheep were assigned to five dietary treatments in a completely randomized block design: 100% concentrate (+ve control; T1), 75% concentrate + 25% soybean hay (T2), 50% concentrate + 50% soybean hay (T3), 25% concentrate + 75% soybean hay (T4), and 100% soybean hay (T5). The study lasted 90 days, followed by a 7 day digestibility trial. Dry matter intake did not differ significantly (P>0.05) among treatments, with values ranging from 939.06 to 1,049.19 g/day. Organic matter intake was significantly higher (P<0.05) in T1, T2, T3, and T4 compared to T5. Soybean hay inclusion exceeding 50% resulted in significantly greater ash intake (P<0.001). Crude protein (CP) intake was highest in T1 (84.82–109.56 g/day; P<0.01), while T1, T3, and T4 exhibited higher digestible CP and metabolic body weight (P<0.05) than T2 and T5. Apparent CP digestibility was significantly higher (P<0.01) in T1 and T3 compared to T2, T4, and T5. Final body weight and average daily gain were significantly higher (P<0.05) in T1, T3, and T4 compared to T2 and T5. T1, T2, T3, and T4 also showed significantly greater total body weight gain and feed conversion efficiency than T5 (P<0.05). Economic analysis revealed marginal rates of return of 1.21 for T3 and 1.51 for T4, both exceeding the minimum acceptable rate for farmers. Considering both growth performance and economic feasibility, T1 (100% concentrate) and T4 (25% concentrate + 75% soybean hay) are recommended as viable supplementation strategies to enhance sheep productivity.

During the dry season, the shortage of quality feeds needed to sustain livestock production has been a major problem in many developing countries, including the kingdom of Lesotho. Agro-allied by-product wastes obtained from the processing of agricultural products can possibly be converted to unconventional sources of animal feed. Therefore, this study evaluated the fibre and anti-nutritional constituents of important agricultural wastes in Lesotho namely, Irish potato peel meal, sweet potato peel meal, sweet orange peel meal and banana peel meal, to determine their feed value because of the negative effect these nutrients can elicit in livestock and poultry at higher levels. Prior to chemical analyses, dried peels of each banana fruit (BF), sweet orange fruit (SOF), sweet potato (SP), and Irish potato (IP) were milled into a fine powder to pass through a 0.5 mm sieve screen by grinding machine (mrc-SM-450 L) and stored in labelled sealed laboratory plastic bottles. The determinations of fibre fractions and anti-nutritional factors in each sample were carried out in triplicates. The fibre fractions differed significantly (p<0.05) among the peels. NDF varied from 31.00% - 39.00%, ADF 15.33% - 24.33%, ADL 3.57% - 11.67%, hemicellulose 10.00% - 22.33% and cellulose 9.00% - 17.33%. Fruit peels had significantly (p<0.05) higher ADF than tuber peels and, lower (p<0.05) hemicellulose than tuber peels. Anti-nutritional factors differed significantly (p<0.05) among the peels, and varied between 1.35% - 5.65% in alkaloid, 0.06% - 0.44% in oxalate, 3.39% - 8.32% in flavonoid and 0.21% - 2.03% in tannin. Flavonoid is highest in all peels except sweet potato peel, while oxalate is lowest. The results showed that fibre constituents levels met ruminant requirements, and anti-nutritional factors were within safe limits for ruminant intake, therefore the peels could be incorporated into their feed as a source of roughage.

Türkiye has 27% of the World’s Papaver species in its flora, and 15 of them are endemic. Poppy (Papaver somniferum L.) is the most cultivated and economically significant species of the Papaver genus. There is a need to study and exploit other Papaver species as well. Poppy is an important strategic plant with a history dating back to 5000 BCE and records of its being valued in the lives of different civilizations, art archives, food (seed), and medicine (opium gum). Although opium gum and seed have been produced for centuries in today’s Türkiye, its cultivation was banned between 1971-74. Years of opium gum experience were destroyed, and after 1974, alkaloid production began to be obtained by processing the dry capsule (unscratched). Today, it is counted as one of the two traditional legal poppy-producing countries in the world. It has the largest legal poppy cultivation area, capsule processing, and alkaloid production factory in the world. The seeds and alkaloids are obtained from the same plant. Türkiye has one of the largest morphine stocks in the world and is capable of meeting 25% of global morphine demand. However, it is insufficient in the production of different alkaloids (noscapine, thebaine, codeine). Seed production is, on average, 20,000 tons, and the capacity has the potential to increase to 40,000 tons with appropriate agricultural techniques.

Phosphorus is essential for plant growth, but mishandling phosphorus-rich waste can harm the environment. This study assessed inorganic phosphorus from fruit and vegetable dumpsite soils and its relation to soil properties. Fifteen (15) soil samples were collected and homogenized into five (5) representative samples each from the dumpsites at depths of 0-15cm, 15-30cm, and 30-60cm and were analyzed for calcium-bound phosphorus (Ca-P), reductant soluble phosphorus (RS-P), Fe-bound Phosphorus (Fe-P), aluminium-bound phosphorus (Al-P), and Soluble/loosely bound P. The data obtained was analyzed using the student’s t-test to compare the different fractions in fruit and vegetable dumpsite soils. The results showed no significant differences between fruit and vegetable dumpsite soils in all the inorganic P fractions. However, vegetable dumpsite soils recorded higher soluble P, Al-P, Fe-P, RS-P, and Ca-P levels of 11.65, 36.29, 41.95, 40.75, and 41.35 mg/kg, respectively. These values were not significantly different from 9.75, 34.01, 39.28, 37.11 and 41.03 mg/kg recorded by fruit dumpsite soil for soluble P, Al-P, Fe-P, RS-P and Ca-P respectively. Results also revealed that reductant soluble P, Calcium bound P, and Na+ with an R2 value of 0.88 had a combined significant influence on the concentration of soluble P. However, the concentration of the inorganic P fractions for vegetable dumpsite soil is in the order; Fe-P> Ca-P>RS-P>Al-P>soluble P, while that of fruit dumpsite soil is in the order; Ca-P>Fe-P> RS-P>Al-P>soluble P. Soluble phosphorus significantly impacts eutrophication due to its rapid release into water. However, low levels of soluble P in fruit and vegetable dumpsite soils are not a major concern. In vegetable dumpsite soil, Fe-P would pose a greater threat during anoxic events while, in fruit dumpsite soil, Ca-P would contribute more to eutrophication due to its high concentration in this soil, especially in alkaline conditions.
