This study analyses implication of COVID- 19 pandemics in the agricultural sector of Turkey. In the study taken measures in the sector are considered. The focus of the paper is twofold. The first objective is to take a glance at COVID 19, how it started, and how affected sectors or businesses. This aim supported by the literature review which is getting a shape recently, on the grounds founded papers were limited. It can be seen that generally all countries suffered from the same problems apart from the countries sectors have problems in common. Lastly, we tried to focus on the agricultural sector especially in Turkey and we presented precautions taken agricultural sector in Turkey. In addition to this to the objective, we tried to synthesize all our findings and present suggestions in case this process prolonged. The originality of the paper comes from it is the first study that draws a general outline for Turkey’s agricultural sector considering the pandemic.

With the effects of various human activities and global warming, pressures on plant species are increasing day by day, living species and living environments are adversely affected. In order to reduce and control these negative effects, a variety of regulatory ecological services are needed to provide both a nutrient environment for animals and to save and maintain their habitat. For this purpose, creating buffer zones at the borders of fence plants and farm areas can be used as a regional supporting mechanism. One of the most important criteria is to use plant species (from Legüminaceae families) which have high nutritional value for animals in farm buffer areas. The selected plants have many functions such as erosion prevention on sloping areas, nutrient retention, aesthetic area creation, flood prevention, odor control. They are the ones that constantly occupy the city's agenda with various environmental problems such as ensuring control of unwanted odors in farm areas and improving visual quality. In this study, it is aimed to determine the plant species that can be suggested to be used in a buffer zone which can be created in order to create aesthetic value in farm areas, to control odor problem and to contribute to studies to create nutrients and to protect ecology.

In this study, the effects of light stimulation at normal (NLS: 154 days) and early (ELS: 140 days) age on some physiological and reproductive traits in dam and sire broiler pure-lines were carried out during the laying period. The study was conducted with A1, A2, A3, A4 dam lines and B1, B2 sire lines up to 43 weeks of age, whose breeding studies were carried out in Eskişehir Geçit Kuşağı Agricultural Research Institute. Live weight and feed consumption were determined during the growing period. In the laying period, in addition to these, the first laying age, 50% yield age, egg yield, hatching egg yield and egg weight were determined. The data obtained were evaluated according to light stimulation age and pure-lines by two factor analysis of variance. NLS and ELS treatments did not significantly affect the body weights of the pure-lines at 20, 24 and 43 weeks of age. However, differences were found significant in terms of body weight at 20, 24 and 43 weeks of age in pure-lines. Lines reached the first laying age at 172 days in NLS, and at 165 days of age in ELS. The 50% yield age was realized at 184 d and 176 d of age in parallel with the first laying age. The effects of light stimulation age on egg yield and hatching egg yield were found significant. In NLS treatment all pure-lines, 5 more eggs were produced in egg yield and hatching egg yield. However, differences in egg yield and weight in pure-lines were found significant. The study results showed that the egg production can be increased by first light stimulation at the 20 weeks of age, provided that at least 2 kg live weight is achieved in broiler pure-lines.

In this study, antibacterial effects of semi-parasitic plant common mistletoe (Viscum album L.), collected from different woody host, extracts on the tomato bacterial cancer and wilt disease agent Clavibacter michiganensis subsp. michiganensis, pepper and tomato bacterial leaf spot disease agent Xanthomonas axonopodis pv. vesicatoria and tomato bacterial leaf spot disease agent Pseudomonas syringae pv.tomato were determined. The common mistletoe collected from pine, pear, acacia and mahaleb trees. The leaves and stems water extracts of common mistletoe were added to Nutrinet agar medium before autoclaving at the final concentrations of 1%, 2.5%, 5% and 10%. The bacterial concentration was adjusted to 108 cfu/ml with spectrophotometer to within an 0.2 at 600 nm. Then, 100 µl of bacterial inoculums were spread over the extracts amended media plates. As a control group, pathogens were plated on the unamended media. The study was established in 3 repetitions and repeated 2 times. At the end of the incubation period, bacteria growing on all treated petri dishes were collected and their density was measured in a spectrophotometer. Based on the results of the study, 1% and 2.5% concentration of the extracts obtained from leaves and stems of common mistletoe collected from different trees were not effective on the bacteria tested, while 5% and 10% concentration of them inhibited the bacterial growth completely (100%). Also, it was observed that there wasn’t difference on the pathogens on the basis of the host where mistletoe was collected. According to the results of this study conducted under in vitro conditions, in vivo studies should be carried out with the common mistletoe extract, which is effective on the bacterial pathogens.

The aim of this study is to screen the recombinant inbred lines (RILs) carrying rye translocation for the semi-dwarf (Rht), photoperiod (Ppd) and vernalization (Vrn) genes. Recombinant inbred lines were obtained by hybridization of bread wheat varieties Tosunbey and Tahirova-2000. Only the lines carrying 1BL.1RS rye translocation from population were used in the study. Parents and all of RILs were found to have Rht-B1a, which is a semi-dwarf allele, and Ppd-D1a allele, which is not susceptible to photoperiod. The vernalization alleles (Vrn-A1, Vrn-B1 and Vrn-D1) in the lines were also determined. It was determined that both parents and all the RILs had vrn-A1 allele, and not Vrn-A1c allele. It was determined that 151 of RILs contained vrn-B1 allele and 154 of them contained Vrn-B1 allele, while 131 of RILs had vrn-D1 allele and 174 of them had Vrn-D1 allele. In addition, molecular screening were carried out for waxy alleles (Wx-A1, Wx-B1 and Wx-D1) which were effective on flour swelling, water holding capacity and shelf life of bread wheat. As a result of the molecular data it was found that 141 of RILs carry all three alleles and named as “normal amylose wheat” and 164 of them had only Wx-A1 and Wx-D1 alleles, as known “low amylose wheat”. The results indicated that the population used in the research could be the subject of some researches, especially drought tolerance, and RILs could be used to develop genetic material carrying rye translocation for wheat breeding programs.

This study was aimed to determine the responses of some sunflower hybrids to drought and low temperature stresses during germination and seedling development period. Sunflower hybrids of Sanbro MR, 63LE113, 64LL62 and Meteor were used in the study. Germination percentage, mean germination time, root and shoot length, root / shoot ratio, seedling fresh and dry weight of the sunflower hybrids were investigated at two temperatures (low 15°C and optimum 25°C) and drought stresses (distilled water, -1.5, -3.0, -4.5 and -6.0 bar) induced by polyethylene glycol 6000. The results of the research showed that there were significant differences among the sunflower hybrids in terms of the investigated characteristics. Increased drought stresses led to decreasing germination percentage, root and shoot length, seedling fresh weight, but caused a prolonged germination time and increased seedling dry weight. No significant change was observed in the germination and seedling development of the sunflower up to drought of -3,0 bar. The root / shoot ratio of sunflower hybrids increased at 15°C. The Sanbro MR had the fastest and highest germination along with the highest seedling fresh and dry weight at low temperature and higher drought stresses. It was concluded that sunflower hybrid Sanbro MR gave better performance under drought and low temperature conditions than the other hybrids.

In this study, pectin was extracted by acid extraction method from pomegranate peel. The temperature, time and particle size which affected pectin yield were optimized using response surface method. As a result of optimization, optimum conditions for pectin extraction from pomegranate peel were determined as 468-568 µm for particle size, 82°C for temperature and 47,5 minutes for extraction time. After the extraction at optimum conditions pectin yield was found to be 25,96%. In addition, pectin that was produced had equivalent weight of 488,01 mg, methoxyl content of 5,74%, the degree of esterification of 47,43%and anhydrogalacturonic acid content of 68,64%. The results showed that the obtained pectin was low methoxyl pectin.

In this study, the milk quality characteristics of Simmental (SIM) and Red-Holstein (RH) breeds raised in a private farm in Aydın were determined. As milk quality properties, the percentages of protein (MPC), lactose (MLC), non-fat dry matter (NFDMC), total dry matter (TDMC), casein (MCC) contents and also milk urea nitrogen (MUN), oleic acid (OA), beta-hydroxybutyric acid (BHBA) and somatic cell count (SCC) were determined. The averages of MPC, MLC, NFDMC, TDMC, MCC, MUN, OA, BHBA and Log10SCC belonging to RH and SIM breeds are 3.38 ± 0.021% and 3.40 ± 0.015%, 4.86 ± 0.028% and 4.81 ± 0.019%, 9.09 ± 0.037 and 9.09 ± 0.025, 11.18 ± 0.069 and 11.23 ± 0.048, 2.50 ± 0.020 and 2.44 ± 0.014, 12.07 ± 0.200 mg / dl and 12.28 ± 0.138 mg / dl, 0.258 ± 0.0095 g / 100 g and 0.255 ± 0.0065 g / 100 g, 0.284 ± 0.138 mmol / L and 0.269 ± 0.0093 mmol / L, and 5.417 ± 0.0173 (261216 cells / ml) and 5.401 ± 0.0118 (251768 cells / ml) were found, respectively. The breed did not differ significantly in milk quality characteristics, except for MCC. The lower SCC level in milk and the suitable level of MUN for both breeds shows that the factors such as maintenance-feeding-housing-herd management in the farm were optimal in this herd.

The present research was conducted to determine the effect of season, lactation number and type score factors on the somatic cell count (SCC) in Black and White cattle raised in the Mediterranean climate zone. 1368 milk samples obtained from 128 cattle were analysed for SCC determination. Significant effects of season, lactation number and type scores on SCC were observed. The results indicate that the necessity to comply with the care and barn cleaning of the cows in the summer and the importance of the type characteristics in the selection programs may be effective in reducing the of SCC.

In this study, we aimed to prepare new calixaren embedded mercapto groups supported liquid membranes and to use them in the transport of heavy metals. For this purpose 5,11,17,23-tetra-tert-butyl-25,27-bis(3-thiol-1-oxypropane)-26,28-dihydroxylcalix[4]arene was synthesized. The synthesized calixarene compounds were fully characterized by spectroscopic and the other techniques. The prepared compounds were supported polyamide liquid membranes and obtained calix[4]aren embedded supported liquid membranes (C@PSMs). The characterization of C@PSM was carried out by FTIR, TGA and elemental analysis techniques. Transport experiments were carried out with Pb(II), Cd(II) and Zn(II) as trace metals, to transport from donor phase to accept phase. From the results, it was calculated flux (J) and recovery (RF) values. The affinity (the percentage of metal ion transferred from the source solution) of a PIM towards a range of divalent cations was found to follow the order Zn(II)> Cd(II)> Pb(II).
