Arjun Bastola | Tika Karki | Santosh Marahatta | Lal Prasad Amgai
Field experiment was conducted in three factorial strip split plot design to evaluate the effect of two establishment methods (EM) i.e. transplanted in puddled soil (Pu-TPR) and direct seeded in zero tillage (ZT-DSR), two residue levels i.e. residue kept at 3 t ha -1 (RK) and no residue (RR) with two nitrogen doses i.e. recommended dose (100 kg N ha -1) (RD) and farmers' dose (50 kg N ha-1) (FD) with six replications with individual plot size of 5.4 m × 6.3 m on rice variety Ram-Dhan during the year 2016. Nitrogen uptake, nitrogen use efficiencies and yield of rice were recorded. Straw nitrogen uptake was significantly higher in ZT-DSR than Pu-TPR. Similarly, grain straw and total nitrogen uptake were significantly higher in residue applied and recommended dose of nitrogen than no-residue applied and farmers-nitrogen dose treatments respectively. Nitrogen efficiency ratio and physiological efficiency index were significantly higher in Pu-TPR and no-residue applied treatments while partial factor productivity was higher in residue applied treatment. All nitrogen use efficiencies like partial factor productivity, nitrogen efficiency ratio and physiological efficiency index were significantly influenced by nitrogen dose and seen higher in recommended dose of nitrogen. Establishment methods had no significant effect on grain yield but straw yield was significantly higher in ZT-DSR but harvest index was seen higher in Pu-TPR. Grain yield and straw yield were significantly higher in residue applied treatment and recommended nitrogen but harvest index was higher in farmers-nitrogen dose.

Derya Balcı | Fatma Handan Giray
In order to gain competitive advantage in national and international markets through globalization, make the competition sustainable, produce products with advanced technologies and innovative activities and make a flexible production in line with changing demand make firms and / or sectors advantageous in global competition. This study aimed at analyzing a competitive analysis of fruit sector through the Diamond Model developed by Michael Eugene Porter in order to demonstrate national and sectoral competitiveness. For this purpose, the current situation of fruit sector, which is an important economic activity in Isparta, was put forward and analyzed its competition level was discussed. The necessary data for the Diamond Model were gathered through face-to-face surveys with 47 large fruit producers and in-depth interviews with the representatives of other related sectors. Although the fruit sector and related sectors have been located close to natural resources and inputs in the neighbourhood in Isparta, an ordinary agglomeration has emerged but it could not be clustered because collaboration culture has not been developed in the sector and intersectoral. This fact decreases the regional competition chance of the sector. However, existence of an easy and continuously communication among all actors in the sector, state supports to sectoral cooperation / organizations, and actors who are compulsory for benefiting these supports in the region should be considered important advantages for a clustering and increasing regional competitiveness power of fruit sector.

Just because of geographical spread, citrus species generally grow in places sensitive to salinity. Testing methods have a significant role in breeding and cultivar development programs. This study was conducted to investigate in vitro salt response of Cleopatra mandarin (Citrus reshni Tan.), sour orange (Citrus aurantium L.), rough lemon (Citrus jambhiri Lush.), Volkamer lemon (Citrus volkameriana Tan & Pasq.), Carrizo citrange (Poncirus trifoliata L. Raf. X Citrus sinensis L. Osbeck) and trifoliate orange (Poncirus trifoliata Raf.) rootstocks at different NaCl concentrations. Seeds were germinated in MS medium with 0, 45, 90 and 135 mM NaCl concentrations. In general, the greatest germination rates in all salt concentrations in Volkamer lemon and sour orange rootstocks and the lowest values were observed in rough lemon and trifoliate orange rootstocks. Present findings revealed that in vitro conditions could reliably be used in salt tolerance tests of citrus rootstocks.

In this study, equipment elements which have been used in Niğde Ömer Halisdemir University campus, were analysed considering various criteria in terms of landscape architecture. In this study, lighting and flooring elements, trash cans, sitting elements etc. were evaluated considering some criteria such as maintenance, design, ergonomics, etc. Within the scope of the study, it has been determined whether the equipment elements in the campus meet the people needs. There are insufficient number of seating elements in the campus, security problems occur due to the lack of lighting elements in certain places. The bus stops in the campus are sufficient numerically, and they are in suitable areas in terms of location. In addition, the number of telephone booths and the number of trash cans in the campus are insufficient. The designs of the equipment elements are similar, and equipment elements have traditional design. As paving elements, key paving stones are used on pedestrian roads, so that in some areas, collapses occur, so fall, snag, etc. on pedestrian roads. Finally, suggestions for using equipment elements in campus areas were developed.

2020
Tarık Balkan | Kenan Kara
Sour cherry (Prunus cerasus L.) (Rosaceae) is a spring fruits. It is not preferred to be consumed as fresh because it is sour, but it is extremely beneficial for human health. In addition to fresh consumption, it is used in the production of fruit juice, syrup, jam, marmalade, cake and ice cream in the food industry. Sour cherry is grown widely in Tokat and 80-85% of the grown cherries are sold to juice factories. Producers mostly adopt chemical control against pests. In this respect, monitoring pesticide residues on sour cherry is extremely important. This study was carried out to determine the pesticide residue levels in samples taken from sour cherry production areas in Tokat province in 2020. The residue analyses were performed by using QuEChERS method and LC-MS / MS (Liquid Chromatography / Tandem Mass Spectrometer). According to the results, the pesticide residue levels were found below the maximum residue limits (MRL) given in Turkish Food Codex (TFC).

2020
Bilgin Taşkın
Kefir; is a fermented milk product which is produced by granules containing a wide variety of microorganisms such as lactic acid bacteria, acetic acid bacteria and yeasts. It is traditionally consumed in many countries. It has been shown in many studies that the polysaccharide structure surrounding the granules which is composed mainly of kefiran molecule has antimicrobial effect against various pathogens as well as many health promoting effects. In this study, 24 h fermented kefir was used with two types of kefir granules for production of kefiran extract. One of them is being sold commercially and the other was collected from private households in a different region of Turkey. Kefiran extraction was carried out from matured kefir granules using three different temperatures, 80°C, 90°C and 100°C. Also, the protein contents of the extracted solutions were determined by Bradford method. Protein content of the extract solutions obtained were measured as 0.001 g/ml. The antibacterial effect of 0.05, 0.1, 1 and 2 mg of this extract against several plant pathogenic bacterial strains belonging to genus Pseudomonas, Xanthomonas, Erwinia ve Clavibacter was investigated in vitro for the first time. For this purpose, two methods, disc diffusion method and spreading method were used. The AN and SD kefir supernatants used as the positive controls in the experiments showed an average of 13-17 mm and 10-14 mm inhibition zones on the isolates, respectively, but the antibacterial effect of kefiran extracts was not observed.

Burak Evren İnanan | Mahir Kanyılmaz
The aim of the present study is to assess the effects Fenugreek (Trigonella foenum-graecum, Fabaceae), sunflower (Helianthus annuus, Asteraceae), green cardamom (Elettaria cardamomum, Zingiberaceae) and seed extracts, which they belonged to three different plant families, on common carp (Cyprinus carpio L.) spermatozoa motility parameters and oxidative stress conditions. For this reason, sperm samples treated with seed extracts at the ratios of 0.1%, %0.5, 1%, and 2%, were incubated at 4°C and sampled at 2nd and 48th hours. Among sperm motility parameters, curvilinear velocity (VCL), average path velocity (VAP), straight-line velocity (VSL), straightness STR), linearity (LIN), and wobble (WOB) were determined by computer-assisted sperm analysis (CASA). According to the results, sunflower and green cardamom seed extracts have attenuated motility parameters at all tested concentrations. However, motility parameters measured in %0.5 of fenugreek seed extract were higher than all other groups including the control at 48th hour. Also, TBARS values as an oxidative stress indicator in this group were decreased. 2% of all seed extracts had negative effects on the sperm samples. Particularly, 2% sunflower seed extract caused the higher oxidative stress. These results indicate that fenugreek seed extract is more proper for the maintenance of common carp spermatozoa at 4°C, comparing to those of sunflower and green cardamom.

2020
Mansur Seymen Seğmenoğlu
Apiculture is one of the agricultural activities carried out widely in our country and in the world. Our society attaches great importance to beekeeping and honey products, especially honey, so bee colony health is very important in the continuity of bee products. There are many factors that can be shown to cause colony loss in bees and one of them is poisoning caused by pesticides. Causes such as improper dosing of pesticides, day-to-day spraying, or potentiation or effect differentiation due to random mixing of drugs may cause collective bee deaths. In this study, 188 dead bee samples (each sample contains approximately 100 g dead bees) from different bee farms, which were collected from beekeepers and brought to Adana Veterinary Control Institute with the suspicion of pesticide poisoning due to intensive deaths, were examined. Qualitative examination was performed by gas chromatography (GC) device. In the examination of dead bee samples, tau-fluvalinate residue was found in 2 samples in 2015 and cypermethrin residue was found in 1 sample in 2016. In 2017 and 2018, no detectable substance was detected in terms of pyrethroid pesticides. In 188 samples which we examined in terms of pyrethroit group pesticides, 1 substance was found to be toxic for bees. This shows, at the samples examined, that pyrethroid pesticides are not involved in bee colony losses in Çukurova.
