Biocomfort conditions, which are related to climate parameters, are a factor that affect almost every aspect of people’s lives. Compatibility in terms of biocomfort also brings many advantages and disadvantages in areas where tourism activities are carried out. For this reason, it is of great importance to identify areas that are suitable and not suitable for biocomfort during the tourism season, especially in areas where tourism activities are carried out. In this study, with the help of GIS, it was aimed to determine the areas that are suitable and not suitable for biocomfort in the city of Samsun in June, July, August and September by using the summer temperature index (Summer Simmer Index = SSI). As a result of the study, it was determined that 1.41% of the province in June and 16.65% in September remained in the cold zone. Apart from this, it was determined that 11.58% of the province in June, 33.27% in July, 21.77% in August and 14.3% in September remained in the second generation, which is considered the most comfortable belt.

This study was conducted to determine the effects of “biofertilizers” (N 8%, P2O5 1%, 9% K2O, 3% Iron, 0.06% Zinc, Bacillus subtilis (GBO3), Bacillus subtilis, Bacillus licheniformis, Bacillus amyloliquefaciens ve Bacillus pumilus) eaf applications on yield and quality parameters of bread wheat at different developmental stages. The experiment carried out for this purpose was conducted in the wheat sowing seasons of 2017-2018 and 2018-2019 at Doğankent location of the Eastern Mediterranean Agricultural Research Institute. In this research, “biofertilizers” leaf applications were applied to the wheat in different stages of development. For this purpose, 4 themes were worked out as; control, tillering, tillering + stem elengation and stem elengation. Biofertilizers doses of 100 gr/da in the first year and 0.75 gr/da in the second year were investigated. As a basic fertilizer for all experiment subjects; 15 kg DAP per decar were given during sowing period and 29 kg Urea during the tillering period, as a result of the research carried out; using biofertilizers in wheat farming, both in tillering and stem elengation periods, increased the yield 12.67% more efficiency in the first year and 13.16% more in the second year than the control subject. There were no statistically significant effects on quality parameters of wheat by using “biofertilizers” in foliar applications.

Genetic improvement in components of economic importance along with maintaining a sufficient amount of variability is always the desired objective in the any maize (Zea mays L.) breeding program which will be handled under the conditions of Haramaya, Eastern Ethiopia. Therefore, an experiment was conducted using (27) and (3) check/control varieties to determine the genetic variability of maize genotypes at Haramaya, eastern Ethiopia. The study results revealed that significantly the tallest plant heights for (PH) were recorded from (3) (170 cm) and (18) (167.5 cm) genotypes whereas the shortest PH were recorded from (13) (117.5 cm) and (23) genotypes (120 cm). Good plant aspects (PA) were obtained from genotype 12, 22 and 26 (PA-1.5) and poor PA were attained from genotype 1 (PA-2.5). Besides, genetic and phenotypic variances were estimated for seven components. The highest genotypic coefficients variation (GCV) and phenotypic coefficients of variation (PCV) were calculated from grain yield (GY – 23.39%). Comparatively the higher GY were attained from the genotypes of 3, 9 and 12. It can be concluded that almost all components of the PCV are greater than the GCV. Superior selected genotypes are recommended to the researchers /breeders to develop disease resistant and high yielder varieties to increase maize production by farmers under Haramaya and other similar agroecologies.

The effects of temperature and pressure processing on myrosinase extracted from fresh broccoli and brown mustard seed was studied. Brown mustard seeds had higher myrosinase activity (2.75 un/mL) than fresh broccoli (0.58 un/mL). The extent of enzyme inactivation increased with pressure (200-800 MPa) and temperature (30-80°C) for both brown mustard seeds and fresh broccoli myrosinase. However, at combinations of lower pressures (200-400 MPa) and temperatures (30-80°C), there was less myrosinase inactivation. When processing at a pressure of 300 MPa with a temperature of 70°C for 10 minutes, there was 65% myrosinase activity for brown mustard while at 300 MPa and 60°C, activity retention in fresh broccoli was 30%. Whereas, the corresponding activity retentions when applying only heat (70°C for 10 minutes) was 35% for brown mustard myrosinase, while there was no measurable myrosinase activity for fresh broccoli (60°C, 10 minutes). Thus, application of moderate pressures (200-400 MPa) on brown mustard and fresh broccoli can potentially be used to retain myrosinase activity needed for subsequent glucosinolate hydrolysis.

Plant growth-promoting rhizobacteria (PGPR) is a beneficial group of free-living soil bacteria that colonize the rhizosphere and are helpful in root growth and development. PGPR plays an important role in plant growth through the production of phytohormones, solubilization of inorganic phosphate, increased iron nutrition via iron-chelating siderophores and volatile compounds that affect the plant metabolism and signalling pathways. Additionally, PGPR shows synergistic and antagonistic interactions with rhizosphere microorganisms and soil which indirectly improve and enhance plant growth rate. Various environmental factors affect the PGPR growth and proliferation in the plants. There are several shortcomings and limitation in the PGPR research which can be addressed through the use of modern approaches and techniques by exploring multidisciplinary research which combines applications in microbiology, biotechnology, nanotechnology, agro-biotechnology, and chemical engineering. Furthermore, PGPR is also known to reduce the emission of greenhouse gases (GHGs), carbon footprint, and also increase the nutrient-use efficiency. Here we describe the importance of PGPR in sustainable agriculture and their role in plant growth and development.

Global urbanization and population growth obstruct the food waste management and cause uncontrolled accumulation of wastes. Ensuring the correct and efficient use and recycling of wastes having high protein content and generated throughout the food production and supply chain is becoming more important both in our country and all over the world. The evaluation of by-products released in the food industry is important for the development of new functional products and for greater economic rate of return on industrial scale. In this respect, bioactive peptides obtained from plant/animal wastes and rich in protein come into prominence. Bioactive peptides are also of great importance for human health because of their functional properties. In this review, functional properties of bioactive peptides obtained from protein-rich food wastes and their bioavailability mechanisms in human gastrointestinal system are discussed.

The species of the Congridae family belonging to the Anguilliformes order are known as conger eel, and are morphologically similar to the eels which are among the species of the Anguillidae family. In both family species, the dorsal and anal fins are combined with the caudal fin. It is easily distinguished from eel species by the appearance of dorsal fin rays at a closer level to the head. There are 195 species belonging to 30 genus distributed in the world seas belonging to the Congridae family. A third genus of 3 species [Ariosoma balearicum (Delaroche, 1809), Gnathophis mystax (Delaroche, 1809) and Conger conger (Linnaeus, 1758)] shows the distribution of Turkish seas. While the first two species have distributed only Turkey's Aegean and Mediterranean seas, C. conger shows the distribution of all our seas. In this review, where morphological and biological characteristics of European conger are distributed in our country, all studies carried out both in our country and abroad are examined in detail and presented together. With this compilation study, especially biological information about species is missing in our country and attention has been made to contribute to the literature.

That agricultural sector is examined closer from every point of view and is restructured in complied with the requirements of the age has to be structured comes to our face as a reality any longer accepted by every sector of the society. The various developments experienced in the world in the recent years have directly or indirectly affected agricultural sector. In the economy of Turkey, one of the countries attracting attention with its rapidly growing, there are many theoretical studies dealing with the direct or indirect contribution of agricultural sector. However, it is necessary to increase the number of the applied studies introducing the existing situation of the sector and enabling to develop the effective policies for the sector. For, it is highly important for the theories put forward in theoretical framework to be supported by empirical analyses in terms of forming effective policy suggestions. In the study, the three sub-sectors were considered such as the subsectors of cereal, legume, and fruit-vegetable and the existing situation of the sector was analyzed by moving from the macro variables. In order to identify the effects of macroeconomic variables (inflation, exchange rate, interest, monetary supply), selected in the direction of the aim of the study, panel cointegration test was utilized. Setting off from this point, when the analysis made in the study is examined for all sectors, it was identified that the variable affecting the sector the most was interest rate. When the results of panel cointegration test between interest rate and agricultural production were examined, while there was a negative directional relationship between the production of subsector “fruit vegetable” and the variable “interest” as expected, it attracts attention that there was a positive relationship between the subsector of cereal legume and interest in contrast to this.

Bu araştırma, farklı azot kaynakları ile yapılan ilave yaprak gübrelemesinin marul (Lactuca sativa L.)’da verim ve nitrat birikimi üzerine etkisini belirlemek amacı ile tarla koşullarında yürütülmüştür. Bitkisel materyal olarak bir adet yaz sıcaklarına dayanıklı kıvırcık marul (cv. ‘Bohemia F1’) çeşidi, yaprak uygulaması olarak da üre (CO(NH2)2), potasyum nitrat (KNO3) ve kalsiyum nitrat (Ca(NO3)2)’ın %0,4, %0,6 ve %0,8’lik dozları kullanılarak yaprak gübrelemesi yapılmıştır. Yaprakta toplam azot değerleri %2,20 (KNO3 %0.4) ile %3,00 (Üre %0,8) arasında değişmiştir. En yüksek nitrat birikimi 2610 mg kg-1 ile Ca(NO3)2’ın %0,8’lik uygulamasında belirlenirken, en düşük nitrat birikimi ise 2070 mg kg-1 ile sadece taban gübrelemesi (NH4NO3) yapılan parselde tespit edilmiştir. Farklı azot kaynakları ile yapılan ilave yaprak gübrelemesi sonucunda marulda en yüksek verim değerleri sırasıyla 4926 kg da-1 (Üre %0,6), 4787 kg da-1 (Üre %0,8) ve 4719 kg da-1 (Ca(NO3)2 %0,6) olarak tespit edilmiştir. Ancak, diğer girdilerin eşit olduğu araştırmada; gübre masraflarını dikkate alındığında karlılık analizinde ilk üç sıra diğer gübrelere göre düşük maliyetinden dolayı, ürenin farklı dozları ile yapılan ilave yaprak gübrelemesinde tespit edilmiştir. Araştırma sonuçlarına göre; karlılık oranları da göz önüne alındığında üre (%0,6) ile yapılan uygulamaların hem yüksek verim hem de yüksek kar elde etmek için daha uygun ve önerilebilir ilave yaprak gübrelemesi olduğu açık bir şekilde söylenebilir.
