Şalgam (Shalgam) beverage, which is manufactured by lactic acid-ethanol fermentation, takes its name from turnip radish and its purple-reddish colour from purple carrot, is a drink with certain turbidity and sour taste. This research was carried out to determine the effect of using an autochthonous starter culture and purple carrot size in şalgam production. For this purpose, with the direct production process, purple carrot in two different sizes (4 cm horizontally cut purple carrot or 12 cm vertically cut purple carrot) and şalgam with the addition of 3% L. plantarum was produced. The added starter culture enabled the fermentation to start quickly and the maximum total acidity and LAB count was reached earlier. Besides, the addition of starter culture significantly affected the overall composition of şalgam. In the production of shalgam beverage, the use of horizontally cut purple carrot and L. plantarum as an autochthonous starter culture can be recommended.

Natural products play an important role in medicine. They have been used extensively in folk medicine to treat various illnesses. In this work, quantitative analysis of phenolic compounds in methanol, acetonitrile and dichloromethane extracts of Rosa canina L. waste seeds were investigated by liquid chromatography coupled with tandem mass spectrometry (LC-MS/MS) LC-MS/MS. Mineral analysis of R. canina seeds was determined by inductively coupled plasma–atomic emission spectrometry (ICP-OES). Fe, Mn, K and Zn were found as chief elements. Quantitative analysis revealed that catechin was the major flavonoid in all extracts. This work offers a viewpoint for recycling the R. canina waste seeds into the economy due to their bioactive content.

Vermicompost fertilizers have started to attract attention in agriculture last years. Various liquid vermicompost fertilizers are produced and used in agriculture and some of them known as vermiliquer, vermi leachate, vermi tea or vermicast with little differences. This study is aimed to determine the effects of foliar application of liquid vermicompost fertilizer on yield and some yield components on some Turkey triticale varieties under Central Anatolian conditions in Kırıkkale province during the growing period 2014-15 and 2015-16. Six different (control, 75, 150, 250, 350 and 450 cc da-1) liquid vermicompost fertilizer doses were applied by the foliar spraying method at the beginning and end of March in both years to the five Turkey triticale varieties (Alperbey, Mikham 2002, Tatlıcak 97, Karma 2000 and Ümranhanım). According to the results, plant height, grain number and grain yield in spike, grain yield per decare, harvest index and protein content results were found to be significant in fertilizer × variety × year interaction. There is also a statistically significant difference between thousand-grain weight and the variety x fertilizer doses interaction, and between varieties and fertilizer doses in terms of spike length. The positive effects of liquid vermicompost fertilizer doses, except 450 cc da-1, were determined in varieties. It was observed that a satisfactory yield can be obtained from 250 cc da-1 in the absence of nitrogen fertilizers as the top fertilizer. It could be deduced that 250-350 cc da-1 doses of vermicompost fertilizer can be applied in triticale based on varying ecological conditions and varieties in Central Anatolian ecological conditions.

The objective of this study was to provide the basic data related to the tractor such as power ratios and annual use along with the production pattern, type of farms, farm size and their fragmentation, soil properties. In order to meet the above objective a survey study was conducted in 2013 in four provinces of the Aegean region namely Aydın, Denizli, İzmir and Manisa.Using a GPS device, the coordinates of the location of the agricultural lands were also found in order to analyze the data for further evaluation and GeoMedia Professional 6.0 CBS software. The results from the study indicated that the annual use of tractors is about 650 hours and the surveyed land is a typical example and resembles the whole country in terms of average land size and fragmented land structure. The total land owned by 305 farmers was calculated to be 4023.1 ha and each farmer has 7.47 ha land. On the other hand, the average parcel size was found to be 0.86 ha. The distance between the parcels ranged between 0.5-10 km mostly while %12 of the lands was out of this range.

In this study aimed to determine the effect of ultrasound and microwave assisted extraction on fatty acids yield. Fatty acid components of Tamarindus Indica (T. Indica) seed were determined using ultrasound assisted microwave extraction method. T. Indica is cultivated in the tropics and in Egypt and India. Its fruits are 12-15 cm long, brown and leguminous. In addition to its positive effects on the digestive system, it is an excellent source of vitamin C and a rich antioxidant. It has also been proven beneficial in keeping blood sugar balanced. Fatty acid components were determined by Gas Chromatography-Mass Spectroscopy (GC-MS) method. In addition, the effects of the solvent on the fatty acid yield were investigated. When the results of the analysis were examined, the highest yield was obtained when ethyl alcohol and methyl alcohol were used as solvents. Another important solvent is acetone. The least product was achieved when hexane was used as solvent. Linoleic acid and arachidic acid were detected in each type of solvent used. Capric acid, ligroseric acid and nervotic acid, which are important fatty acids, are detected only in methyl alcohol extraction. The ultrasound assisted microwave extraction method was found to be much faster than the traditional Soxhlet extraction method.

The compost product, which offers many benefits such as the evaluation of organic wastes, improvement of soil structure, neutralization of toxins and pH balance of the soil, has significant potential for the improvement of our country's lands. Considering the development of animal existence in our country, the production of compost product to be obtained from feces, which is the product of these animal beings, is an issue that needs to be emphasized. The choice of plant location, which must be determined for an investment to be made for the acquisition of this product emerges as a separate problem. For this reason, in this study, the order of optimality among the alternatives for compost plant installation is considered as a multi-criteria decision making problem. For this purpose, the criteria determined for 10 clusters with the potential of 35,829 animals that can produce compost in Samsun were weighted by the SWARA method. The optimal ranking of these 10 compost clusters was carried out using the COCOSO and WASPAS methods, by means of the criteria weights taken into consideration. According to the ranking results obtained from both methods, it was determined that the cluster number 27 was in the first rank, the cluster no 13 was in the second rank, and the cluster no 14 was in the third rank.

The methods applied for yield increases per unit animal are also progressing rapidly, along with the rapid progress of agricultural and animal production in parallel with the rapidly developing population and the food demand. The increase in animal products increases the environmental impacts per unit of animal product. With the increase in animal wastes in recent years, greenhouse gas emissions have increased even more, thus negatively affecting the environment and animal health. In order to prevent this negative effect, sustainable methods and strategic measures related to animal feeding and care are important in order to reduce the emission of harmful greenhouse gases. Methane, which is the second most important greenhouse gas, is found in large amounts in the atmosphere as a molecule, the accumulation of this gas in the atmosphere more than CO₂ increases the interest in this subject. Different practices related to the nutrition of ruminant animals (use of feed additives, feeding strategies) in order to optimize rumen conditions and increase productivity per unit animal is a developing area. Sharing this information with animal breeders will also benefit the environment, and therefore human and animal health, in terms of reducing both methane and nitrogen emissions. In ruminant animals, it can cause a loss of 2-12% of the gross energy taken with the feed so that the methane gas can be removed from the body. There are many studies on feeding to reduce nitrogen losses in faeces and urine, which cause methane emissions for ruminants, and many of these studies still do not reach a permanent conclusion. The reduction in enteric CH₄ emissions to be made must be tailored to the specific needs of farmers and livestock, and to be cost-effective. In our study, it is aimed to compile animal feeding strategies and reduction of methane emissions under different conditions.

Wheat is an important cereal product because of its nutritional value, economy, culture, and history. Einkorn (Triticum monococcum L.) assumed as the oldest wheat. Einkorn locally called “siyez” has recently become popular as a super grain with the thought of being very nutritious in Turkey. In this study, the contents of macrominerals (Na, Mg, Ca, and K) and microminerals (Cr, Cu, Fe, Mn and Zn) in twenty-one einkorn samples collected from different cultivation areas in Kastamonu were determined by using an inductively coupled plasma-optical emission spectrometry following microwave-assisted acid digestion. The results were compared with those analyzed in einkorn and other wheat types in the literature. Average concentrations of K, Ca, Mg, Na, Fe, Zn, Mn, Cr and Cu analyzed in einkorn samples were found as 3712, 1303, 656, 53, 167, 34, 29, 0,7 and 0,6 mg kg-1, respectively. The literature comparison revealed that the investigated einkorn samples were richer in terms of Ca and Fe contents compared to einkorn, emmer, spelt, buckwheat, and durum wheat samples grown in our country and different countries.
