Abstract:
In this study, some heavy metal concentrations (Cu, Cd, Pb, Cr, Mn and Zn) were seasonally determined in water to evaluate of the quality of the Beyler Dam Lake. The average concentrations of heavy metals analyzed in water samples for cold and hot season were Cu: 11.53, 13.23; Cd: 0.85, 0.97; Pb: 13.77, 16.26; Cr: 2.88, 3.48; Mn: 1.94, 1.71; and Zn: 7.57, 8.20 ppb, respectively. The annual average (AA) concentrations of heavy metals were Cu: 12.38; Cd: 0.91, Pb: 15.01, Cr: 3.18; Mn: 1.82; and Zn: 7.88 ppb. In general, the heavy metal concentrations were found to be higher in hot season than the cold season. It was observed that none of the heavy metals assessed exceeded the limits specified in the Turkish Water Pollution Control Regulation. The Beyler Dam Lake was classified as Class I for all the heavy metals except Pb for which it was classified as Class II. These results indicate that the lake is not polluted by the heavy metals. However, relatively high Pb levels seek further research to identify the source. The lake water can be used for agricultural activities but should continue to be monitored.

Abstract:
Tea (Camellia sinensis (L.) O. Kuntze) is the second most-consumed non-alcoholic beverage in the world after water. The health-beneficial properties of tea, known to contain more than 4000 bioactive substances, of which about one-third consist of polyphenols, are increasingly well understood. The medicinal properties of the tea plant have been proven by laboratory and clinical studies to have an anti-cancer effect, benefits for dental health, protect against Alzheimer with anti-paralytic, anti-diabetic, and antiparkinson properties, and its use against skin diseases. However, it is known that the tea plant, which requires plenty of fertilizer, can cause excessive pollution of the groundwater when chemical fertilizers are washed away with precipitation in the areas where it is grown. In order to eliminate this negative situation, studies regarding organic and microbial fertilizers that are more environmentally friendly and do not harm the soil and human health that could be substituted for chemical fertilizers as much as possible or mitigate their use and enable to grow products of adequate amount and quality should be accelerated. The aim of this review is to bring together scientific information about the characteristics and health effects of tea and organic tea cultivation.

Abstract:
Erzurum is one of the provinces in Turkey where the Instrument for Pre-Accession Assistance Rural Development (IPARD) program will be implemented in the first stage. In this study, we determined the status of the existing enterprises in Erzurum and measured their capacity to comply with the IPARD program in relation to the "Investments for Restructuring Agricultural Enterprises and Reaching Community Standards" measure. This was conducted in 33 barns in 11 villages in the central districts of Erzurum Province. The current situation of animal shelters in central districts of Erzurum province was compared with European Union (EU) standards required in animal shelters. In addition, rural development and the basis on which documents give directions in Turkey, IPARD, and IPARD measures related to the subject of study are given general information. It has been concluded that the existing animal shelters in Erzurum are generally far from the EU standards required within the scope of the IPARD program, and it is challenging for existing animal shelters to meet EU standards by modernizing them. Therefore, in Erzurum province, it will be appropriate for the livestock enterprises that want to take advantage of the IPARD program's “Investments for the Restructuring of Agricultural Enterprises and Reaching Community Standards” measure, instead of modernizing their existing shelters, which the Program allows, by building new animal shelters. In addition, the Agriculture and Rural Development Support Institution, which is the implementer of the IPARD program, should inform the enterprises wishing to benefit from the program to build new animal shelters.

Abstract:
Salinity stress is one of the important factors affecting all growth processes, from seed germination to seedling development, plant growth, yield and quality. In this study, the effects of serotonin treatments on the germination of pepper seeds (Capsicum annum L.) under salt stress were investigated. Different doses of salt (0, 75 and 150 mM NaCl) and serotonin (S0:0 µM, S1:5 µM, S2:10 µM, S3:15 µM, S4: 20 µM) were used. The applied seeds were placed between the papers in petri dishes, watered with the prepared salt solutions and left to germinate at 25 °C. In the study, parameters related to germination percentage, germination speed, mean germination time, daily mean germination time, peak value and germination value were investigated. As a result of the research, it was determined that the germination of pepper seeds decreased in parallel with increasing salt concentrations, and this negative effect of salt stress decreased with serotonin applications. Although it changes depending on the serotonin doses, it has been observed that significant effects occur on the measured germination parameters, and the best germination was observed at S1 and S2 doses. It is thought that the application of serotonin will have positive effects on the germination of pepper seeds under salt stress, and these effects may also occur during the plant growth period.

Abstract:
Ulva lactuca is one of the macro-epiphytes of farmed seaweeds Kappaphycus spp. and Eucheuma denticulatum in Tawi-Tawi, southern Philippines, especially during the summer season, which affects the growth and health of farmed seaweeds. In this study, the abundance of culturable heterotrophic marine bacteria from U. lactuca associated with farmed seaweeds Kappaphycus spp. and E. denticulatum was investigated in the seaweed farms of Tongsibalo, Sibutu, Tawi-Tawi, southern Philippines, using serial dilution procedure. Results revealed that the average bacterial counts obtained from U. lactuca associated with Kappaphycus alvarezii, K. striatus, and E. denticulatum were 2.48 x 1010 CFU g-1, 1.14 x 1012 CFU g-1, and 1.32 x 1011 CFU g-1, respectively. In addition, agar-digesting bacteria were observed from U. lactuca samples associated with K. alvarezii and K. striatus manifested by the depression and liquefaction of the marine agar after 2-3 days which were suspected as pathogenic bacteria causing ice-ice disease. Therefore, U. lactuca may serve as a vector for these potential pathogens to farmed seaweeds.

Abstract:
Triticale (xTriticosecale Wittmack) is a grain used in animal feed and is known for its high efficiency, high nutritional quality and resistance to stress factors. Triticale is an alternative plant used for the utilization of marginal areas due to these properties. This study was carried out at three different locations in Erzincan and Muş province and Pasinler districts of Erzurum province. Two candidate line and registered triticale varieties (Umranhanım) and 22 triticale lines in the advanced breeding stage were assessed comparatively in terms of efficiency yield and cold resistance parameters. According to the results of this study, Candidate-2 and Line (1, 6, 8, 11, 15, 17, and 18) genotypes were the prominent genotypes in terms of yield. In addition, low precipitation in May and June caused serious losses in yield. Because this period is the pollination period for grains in the Eastern Anatolia Region. Additional irrigation may be recommended in years when precipitation in this period is insufficient. In addition, it has been concluded that it is important to include cold test studies in breeding programs in regions where winter damage is experienced intensively as well as included in the selections.

Abstract:
In the study, it has been tried to determine the dimensions of seasonal female and child labor employed in cotton agriculture in Mardin province and the factors that are effective in the seasonal agricultural workers working in cotton harvesting themselves and their children. For this purpose, the data obtained by face-to-face interviews with 150 seasonal female workers in the cotton-producing villages of Mardin province were determined by simple random sampling method. It was used in the analysis of the probit model with the LIMDEP statistical program. In the study, according to the results of the CART analysis, it was determined that the most important factor affecting the annual income level of female working in the cotton harvest is the annual working period and the education level of the children. In the probit model, which predicts whether female working in the cotton harvest business have children under the age of 18, the employee's nationality other than the Turkish Republic, the number of children under the age of 18 working in the cotton harvest business, and the probability of the children of those with social security other than SSI (green card, etc.) increases, the probability of being married decreases. It can be suggested that female working in the cotton harvest in Mardin and their children under the age of 18 can become SSI employees, raise their living standards, and improve social, accommodation and nutrition education conditions.

Abstract:
Aquaculture production is increasing day by day to meet the protein need of the global population. Various feed additives are used in aquaculture to enhance growth, stimulate immunity, prevent diseases, and strengthen the antioxidant status of fish. Phytochemicals attract attention among these feed additives. As phytochemicals are natural products, they are considered to be safe for fish, humans, and the environment. In this paper, we reviewed recent studies that utilize phytochemicals as feed additives in cultured fish species. In agreement with the available literature, we inferred that phytochemicals could be used in aquaculture. However, as some studies reported undesirable effects on growth, we believe that phytochemicals are more effective in immunostimulation and enhancing antioxidant status rather than growth-promoting. Possible reasons for growth retardation were emphasized. Although available evidence suggests that phytochemicals display beneficial effects, we discussed the possible use of phytochemical combinations to obtain even more desirable results. To conclude, we think that phytochemicals can exert synergistic effects, and this approach should be investigated in future studies.

Abstract:
This study aims to investigate the effect of Salicylic acid (2 mM), Folic acid (5 mg L−1) and Ascorbic acid (2 mM) treatments on the shelf life and quality of 'Belstar F1' broccoli variety. Treated broccoli heads were stored at 21±2˚C for 4 days in plastic containers with lids. It is determined that at the end of the storage period, the lowest weight loss (2.74%), total soluble solids (8.07%), pH value (7.14) and the highest amount of titratable acidity (0.12%) were found in the group treated with ascorbic acid and the least change in color parameters (L*; 29.41, a*; -4.59, b*; 10.78) and the highest total chlorophyll content (0.32 mg/g) in the group treated with folic acid. It is thought that the effects of ascorbic acid, salicylic acid and folic acid treatment at postharvest storage period should be investigated in detail in molecular and biochemical studies for more concrete data.

Abstract:
The aim of this study was to determine the effects of the addition of Safflower, Sunflower and Corn vegetable oils to dairy cattle rations on in vitro gas and methane production, true dry matter (TDMD), organic matter (TOMD) and NDF (TNDFD) digestibilities values ​​and microbial protein (MP) production. Dairy cattle TMR ration consisting of milk feed, corn silage, alfalfa hay and meadow hay was prepared as the control group, and the experimental groups were prepared with the addition of safflower, sunflower and corn vegetable oils at the level of 3% in each of the control groups, respectively. Vegetable oils added to the diet significantly affected in vitro gas production and organic matter digestibility (OMD). Methane (ml) production values ​​in the experimental groups varied between 10.00 and 10.71 ml. The Metabolic energy (ME) and OMD values ​​of the control and experimental groups varied between 7.00 and 7.29 MJ/kg DM and between 53.78 and 51.20. TDMD values ​​of the rations were determined between 48.49 and 52.63%. While the control group had the highest TDMD value, the ration containing safflower oil had the lowest TDMD value. TNDFS values ​​of the rations varied between 67.26 and 68.80%. As a result; Since the vegetable oils added to the ration increase the net energy lactation (NEL) content of the ration, it can be said that it used to meet the energy needs of high milk yielding cattle in the lactation period, provided that they do not exceed the upper limits specified in the literature.
