Many scientific studies are conducted directly or indirectly with humans, animals, and plants. We believe that body electricity, which is generated and constantly present in the bodies of living beings, should be considered in scientific studies as an effective factor for production activity. We believe that body electricity should be included in the environment to bring the rumen fluids of sheep used in Daisy II rumen simulators closer to reality. In this way, the most realistic environment is created by adding the influencing factors of body electricity and many factors that can affect the outcome. The study was conducted on a total of 16 Karayaka ewes, including 4 lambs, 4 one-year-old ewes, 4 pregnant ewes and 4 lactating ewes. The data obtained in the study were collected by measuring the body electricity of the animals before and after grazing in 3 different periods for each group. At the end of the study, it was found that the value of body electricity of sheep determined at 0.12±0.001 v (volt) before feeding was higher than the value determined at 0.09±0.002 v after feeding. The difference between the two values was found to be statistically significant (P<0.05). However, it was found that the fact that the live weights of the animals in the groups were different and they were in different physiological periods did not cause a significant (P>0.05) difference in the electrical body currents before and after feeding (except in lambs (P<0.05)). It can be said that the measurements made in other periods and groups can change the electrical body currents after feeding and that the electrical body currents differ according to the animals fed in the barn, especially during the grazing period, before going to pasture and when returning to pasture.

In this study, the effects of hazelnut husk on growth, quality parameters, and nutrient content of primrose were evaluated. For this purpose, thirteen different growing media were prepared by mixing fresh hazelnut husk (FHH) and mature husk wastes (MHH) with peat at different rates. Some physical and chemical properties of the media and nutrient analyses were made for the nutritional status of the plants. The study was carried out in greenhouse conditions with four replications according to the randomized plot design. The aeration capacity and easily available content of the growing media is within the limit values, the medias with 50% FHH and MHH were prominent in terms of air-water balance. The effect of the medium on the aesthetic appearance, total shoot, leaf, and flower number of the primrose was not significant, but it was effective on flower weight, plant height, and root fresh-dry weight. In terms of plant root-shoot development, 30% FHH and 50% MHH were prominent. The media have caused significant differences in nutrient concentrations in primrose except for nitrogen, phosphorus, and copper. The leaf phosphorus concentration was high, nitrogen and potassium concentrations were within the limit value range, iron was sufficient, and manganese and copper were insufficient, while zinc was mostly lower than limit values. When all the data are evaluated, 50% ratios of hazelnut husks can be recommended in primrose cultivation and hazelnut husk can be evaluate in ornamental plant cultivation as a growing media.

The aim of the study was to investigate the effect of submerged fermentation with Lactobacillus spp. on the nutritional composition of Agaricus bisporus cap and stem. Fresh A. bisporus was provided, and the cap and stem parts were separated and cut into small pieces. Afterward, distilled water (400 ml) and urea (8.4 g) were added to the mushroom parts (100 g) and placed in different fermentation flasks. The fermentation flasks containing mushroom caps or stems were divided into two groups, and the pH levels of the fermentation medium were adjusted to 6 and 7. Fermentation flasks were autoclaved at 121°C for 15 minutes and Lactobacillus spp. was inoculated to each flask at 1 ml (108 CFU/ml). A positive control group was formed by allocating one uninoculated flask for each replicate of each pH value. Fermentation flasks were incubated for 48 hours at 30°C. After fermentation, fermented and inoculated mushroom cap and stem were analyzed to determine the crude protein, ash content, Lactobacillus spp. count and pH value. Lactobacillus spp. count was higher (P=0.028) in the pH 6 group of mushroom cap and tended to be higher (P=0.078) in the pH 6 group of mushroom stems compared with the pH 7 group. Submerged fermentation decreased (P<0.001) the ash content of the mushroom cap and stem in both pH values except the cap with pH 7 compared with the uninoculated mushroom. Similarly, the fermented mushroom cap and stem had lower (P<0.01) final pH values in both initial pH values. Lactobacillus spp. increased (P<0.001) the crude protein content of the mushroom cap with pH 6 but did not alter the crude protein content with pH 7. Besides, submerged fermentation decreased (P<0.001) the crude protein content of mushroom stem with both pH values. The results indicate that submerged fermentation using Lactobacillus spp. can be used to improve the nutritional composition of mushroom caps with pH 6.

Crop yield is largely influenced by the seedling quality and establishment. Seedling density is an important factor that plays a vital role in producing quality seedlings. Seedling growth characteristics of cabbage cv. kf-65 was evaluated at four inter row and intra row spacing: 0.5cm×1.0cm, 1.0cm×1.0cm, 1.5cm×1.5cm, and 2.0cm×2.0cm in the field of Institute of Agriculture and Animal Science, Lamjung Campus during September-October, 2018. Seed germination was 96% under a partially controlled germinator in the lab whereas mean germination in the field was found to be 62%. Treatments were laid out in Randomized Complete Block Design with five replications. Data was collected after 23 days using the destructive sampling method. Plant height, leaf number, leaf area, fresh shoot and root weight and % dry matter was recorded from five samples from each replication of every treatment. Plant population had a significant effect on plant leaf area, fresh shoot and root weight and % dry weight. The 2.0cm×2.0cm spacing had significantly higher leaf area (25.3cm2), fresh shoot (1.33g) and root weight (0.06g). Dry weight % (23%) was significantly higher for 1.5cm×1.5cm spacing. The result indicates that wider spacing (≥ 2cm) was found to be favourable to obtaining robust and quality seedlings.

This study conducted in Gasabo District, Nyacyonga marshland aimed to investigate the effect of water hyacinth (Eichhornia crassipes) organic fertilizer on the vegetative growth of the Royal Chantenay variety of carrot (Daucus carota). The experiment was conducted using a randomized complete block design (RCBD) with three replications. Four treatments were applied: T1 (control, no fertilizer), T2 (NPK 17-17-17), T3 (25% water hyacinth organic fertilizer + 75% NPK 17-17-17), and T4 (50% water hyacinth organic fertilizer + 50% NPK 17-17-17). The growth parameters assessed included plant height, leaf number, and root diameter. Results showed that the application of water hyacinth organic fertilizer significantly influenced the vegetative growth of Royal Chantenay carrot plants. T3 and T4 treatments enhanced plant height, leaf number, and root diameter compared to the control (T1) and NPK 17-17-17 (T2). The highest vegetative growth parameters were observed in T4, indicating that a higher concentration of water hyacinth organic fertilizer positively affected the growth of carrot plants. The findings suggest that water hyacinth organic fertilizer can be a viable alternative to chemical fertilizers in promoting the vegetative growth of Royal Chantenay carrot plants. The utilization of water hyacinth as an organic fertilizer can contribute to sustainable agricultural practices by reducing dependence on synthetic inputs.

The aim of this study was to investigate food safety knowledge levels according to the socio-demographic profiles of young food handlers and to find out the determinants of the knowledge level. A cross-sectional survey was conducted in Türkiye; it consisted of sections including hygienic design, freezing and thawing, preparation, cooking and reheating, service, storage, and foodborne diseases sections. The food safety knowledge level differed according to gender, age, income, grade level, and intership status. Participants who coded 60% of the survey statements correctly were considered to have “good” food safety knowledge. Knowledge about cooking and reheating, foodborne diseases, and service was found to be at a poor level, but food safety knowledge (overall) was good (68%). The correct score ratio was found to be the highest for hygienic design. Binary logistic regression presented that gender, income, grade level, and internship status significantly affected knowledge level. The strongest predictors were found to be income of $638-$850 (exp (β)=12.9) and more than $850 (exp (β)=4.6), respectively. This study highlights that female students under the age of 25 with an income of more than $638, who have not yet completed an internship, have the highest level of food safety knowledge. This study presented a holistic approach to the food safety knowledge of young food handlers. These insights can contribute to the development of hygiene/sanitation and food safety course content for culinary and gastronomy students.

Kaymak is a traditional Turkish dairy product with high fat and moisture, and low protein content. According to the Turkish Food Codex, Kaymak must contain at least 60% milk fat. Obesity is one of the most important health problems of our era, and there have been many initiatives to reduce the fat content of ready-to eat consumer products. In this study, the effect of emulsifying salts (trisodium citrate, disodium phosphate and tetrasodium pyrophosphate) on texture and sensory properties of reduced fat Kaymak (30% fat) was investigated. Emulsifying salts were used in the manufacture at two different concentrations (5 and 10 mM) and a reduced fat Kaymak without emulsifying salts was used as control. Manufacturing reduced fat Kaymak with 10 mM trisodium citrate and 5 mM tetrasodium pyrophosphate increased Kaymak hardness. Samples manufactured with 10 mM trisodium citrate exhibited the highest sensory quality, while Kaymaks manufactured with 10 mM tetrasodium pyrophosphate received lowest sensory scores. In conclusion, 10 mM trisodium citrate successfully improved textural and sensory properties of reduced fat Kaymak.

This study was conducted to determine the effects of different doses of Lactobacillus plantarum (LP) inoculation into triticale silage on fermentation, quality, feed value, and aerobic stability. This study used three doses of LP bacteria strains (MF098786 strain) isolated from homemade pickles as inoculants. As LP dose, 1×106, 1×108 and 1×109 cfu/mL levels were used. The LP inoculation was applied by spraying onto by using a sterile injector at 1 mL per 1 kg material. The prepared silages were incubated for 60 d. The treatment groups in the study consisted of triticale control (TC), 1×106 (LP6T), 1×108 (LP8T) and 1×109 cfu/kg DM (LP9T) LP inoculated triticale. The LP inoculation of triticale silage improved silage fermentation, chemical and microbiological properties, silage quality, and feed value, and aerobic stability of the product, regardless of dose application. This application did not change the silage's organic matter, ash, and hemicellulose contents but decreased the crude fiber, neutral detergent fiber, and acid detergent fiber contents. While there was no significant change in color parameters in all silages, a decrease in the ultimate pH value, and improvement in Flieg score and RFV were detected. The LP inoculation into triticale silage increased the number of lactic acid bacteria and decreased the number of yeast in the silages. This application improved the total digestible nutrient and energy values of LP9T silage compared with other silages. When LP doses were evaluated within themselves, it was determined that all doses gave almost similar results in terms of the parameters studied. However, when the data obtained from the research are evaluated as a whole, LP inoculation at the level of 1×109 cfu/mL can be recommended to triticale silage, because of the positive effects of silage on total digestible nutrient, digestible energy, metabolizable energy, and net energy contents.

Bu çalışma, farklı düzeylerde defne (Laurus nobilis L.) yaprağı tozu (DYT) katkısının yonca silajlarında kimyasal kompozisyonun, in vitro gaz üretim parametrelerinin (metabolize edilebilir enerji, in vitro organik madde sindirilebilirliği ve net enerji laktasyonu) ve bazı fermentasyon özelliklerinin belirlenmesi amacıyla yapılmıştır. Defne yaprağı tozu, yoncaya %0 (kontrol), %0,5 (DYT05), %1,0 (DYT10), %1,5 (DYT15), %2,0 (DYT20), %4,0 (DYT40) ve %8,0 (DYT80) düzeylerinde ilave edilerek 75 gün boyunca silolanmıştır. Araştırma sonunda, kontrol grubuna göre DYT05 grubunda yonca silajının kuru madde içeriği azalmış, DYT20, DYT40 ve DYT80 gruplarında ise kuru madde içeriği artmıştır. DYT80 grubunda ham kül içeriği düşük bulunmuştur. DYT10 ve daha yüksek düzeyler silajın pH’sını; DYT20 ve daha yüksek düzeylerse laktik asit içeriğini önemli düzeyde düşürmüştür. Defne yaprağı muamelesi, silajların NDF, ADF, ham protein, ham yağ, asetik asit, propiyonik asit, in vitro gaz üretim parametrelerini etkilememiştir. Araştırma silajlarının tamamında bütirik asit ve amonyak azot içeriği tespit edilmemiştir. Sonuç olarak, DYT’nin yonca silajlarında %1 düzeyinde kullanılabileceği ve pozitif katkısının olabileceği sonucuna varılmıştır.

Bitki gelişimini şekillendiren en önemli faktörlerden birisi topraktaki besin elementleridir. Bitki beslenmesi için mutlak gerekli besin elementlerinden olan demir (Fe) bitki büyümesi ve gelişiminde önemli bir yere sahiptir. Bu sebeple tarım topraklarında Fe konsantrasyonunun değişimi konusunda çok sayıda çalışma yapılmıştır. Oysa orman ağaçlarının yetiştiği topraklarda konu ile ilgili çalışma sayısı oldukça sınırlıdır. Bu çalışmada Fe’in farklı orman ağaçlarının doğal olarak yetiştiği topraklarda topraktaki ve bitki organlarındaki konsantrasyonlarının incelenmesi amaçlanmıştır. Çalışma kapsamında karaçam, sarıçam, göknar ve kayın türlerinden yaprak, kabuk, odun, kozalak ve kök örnekleri ile her ağacın dibinden yüzey, orta ve derin topraklardan numuneler alınmıştır. Çalışma sonucunda Fe konsantrasyonlarının bitkilerde, topraktakinden çok daha düşük konsantrasyonlarda olduğu belirlenmiştir. Bitki organlarında elde edilen en yüksek Fe konsantrasyonu kayın köklerinde elde edilmiş olup 529,32 ppm’dir. Oysa topraklardaki Fe konsantrasyonunun 8253,91 ppm ile 16848,88 ppm arasında değiştiği belirlenmiştir.
