Fatma Ergün
In this study, it was investigated the total amounts of phenolic and flavonoid substances and antioxidant activities in different solvent extracts of Lonicera iberica M. Bieb. wild fruit. Total phenolic contents of the extracts were determined as equivalent to gallic acid using Folin-Ciocalteu reagent, and total flavonoid contents as equivalent to quercetin by aluminium nitrate method. In addition, the antioxidant properties of the extracts were determined using free radical scavenging (DPPH) and reducing power (FRAP) methods. The amount of total phenolic substance of L. iberica fruits in hexane and methanol extracts was calculated as 30.96 ± 0.67 mg of GAE / g and 23.70 ± 1.56 mg of GAE / g, respectively. In addition, the amount of total flavonoid substance was calculated as 46.50 ± 8.54 mg of QE / g and 42.09 ± 2.58 mg of QE / g, respectively. It was determined that DPPH radical scavenging activity correlated with total phenolic and flavonoid amount of substance, and L. iberica had a strong antioxidant effect. It is predicted that our study will shed light on new researches, since it is the first study done with L. Iberica fruits in this field.

Impacts of Climate Changes on Plant-Beneficial Microorganism Interactions Full text
2021
Kubilay Kurtulus Bastas
Global climate is estimated to change drastically over the next century and the ecosystems will be affected in this changing environment. Plant-associated beneficial microorganisms can stimulate plant growth and increase resistance to biotic and abiotic stresses. Nowadays, the effects of climate change factors such as increased carbon dioxide (CO2), drought and warming on plant-beneficial microorganism interactions are increasingly being investigated in the scope of plant growth and health. Recent studies have shown that high CO2 level has a positive effect on the abundance of mycorrhizal fungi, whereas the effects on plant growth promoting bacteria and endophytic fungi are more variable. Elevated CO2 conditions lead to increased colonization of beneficial fungi. Additionally, the results of increasing CO2 levels, warming and drought, depend upon the plant and the microbial genotype. Also, plant growth promoting microorganisms, especially bacteria, positively affect plants exposed to drought stress. Altered communities of beneficial microorganisms depending on climate changes, might have to compete with different microbial communities and, therefore microbial activities may also get affected. This work presents that climate change is an important factor affecting microorganism and plant interactions, needs to take into consideration the adaptation processes in plants and microorganisms and might require the selection of adapted plant cultivars.

The aim of the study was to describe the scenario of the present condition of production and management system of dairy buffalo at Haor areas of Sylhet in Bangladesh. Data were collected between February 2019 and January 2020. Sixty dairy farmers and thirty indigenous dairy buffaloes were selected for the study purpose. All respondent farmers were male and 65% were in between 40 to 50 years of age. Parity number had a significant relation in response of body weight. Quality analysis of milk showed that buffaloes which were reared at Haor areas have more fat content on an average 7.88% than buffaloes which were reared conventional dairy farm containing 7.34%. Price of buffalo’s milk and meat were varied with the seasonal changes, lower in winter season. All farmers fed the buffaloes only with green grass in winter. Four major diseases of buffaloes were found in Haor areas where the percentage of foot and mouth diseases was 15.59% followed by black quarter (11.01%), anthrax (7.34%) and hemorrhagic septicemia (6.42%). The buffaloes were not dewormed so parasitic infestations dramatically increased and easily transferred from one to another. The farmers had not enough knowledge about regular vaccination. But in contrast with profitability, total benefit cost ratio from buffalo rearing was 1:1.56 annually.

The aim of this investigation was to determine appropriate perennial grasses and their most suitable mixture ratios, which can be grown with alfalfa in binary mixtures. The research was conducted during 2009-2011 in Isparta (37.50 °N, 30.32 °E), located in the Western Mediterranean climate conditions. In the study, alfalfa was planted as a binary mixture with perennial ryegrass (Lolium perenne L.), orchardgrass (Dactylis glomerata L.), meadow fescue (Festuca pratensis Huds.), and smooth bromegrass (Bromus inermis Leyss.) in a randomized block design with three replications. Sowing ratios of alfalfa in the mixtures varied 20, 30, and 40%, and grass species ratios were 80, 70, and 60%. In the study, significant differences were found among the applications regarding hay yield, crude protein content, crude protein yield, NDF, ADF, land equivalent ratio (LER), and grass ratio in the hay (GR). The highest hay yield was obtained from alfalfa + orchardgrass and alfalfa + smooth bromegrass binary mixtures (25.98 and 25.78 t ha-1, respectively). Alfalfa + perennial ryegrass and alfalfa + meadow fescue mixtures gave the highest crude protein contents as 14.93 and 14.80%, respectively. The highest LER values were observed on perennial ryegrass and smooth bromegrass binary mixtures, and the highest grass ratios were determined in orchardgrass and smooth bromegrass mixtures made with alfalfa. Increasing the alfalfa sowing ratio in the mixtures positively affected all quality characteristics such as crude protein, NDF, and ADF. It was concluded that orchardgrass and smooth bromegrass binary mixtures with alfalfa produced high yield and quality hay and that the mixture should contain 40% alfalfa and 60% grass.

Organic Agricultural products are natural food products that are checked and certified by authorized institutions at all stages of cultivation and presented to the consumer. In this study, the knowledge and practices of soil agriculture farmers in Amasya province about Organic Agriculture production were investigated by face-to-face survey method. In the survey, the local producers were asked what Organic Agriculture is in general, their status of producing Organic Agriculture, whether they fulfill the Organic Agriculture requirements for Organic Agriculture production. The obtained data were presented numerically and proportionally. Data were also analyzed with the Decision Tree method using the CART (Classification and Regression Tree) algorithm. According to the findings, although the local farmers declared that they knew what Organic Agriculture was at a high level, it was seen that none of the producers fulfilled the requirements of Organic Agriculture in practice. According to the survey data, while the farmers reported that they received the information about Organic Agriculture from TV-radio and the internet to a large extent (58.5%), a very small percentage (11%) stated that they received training. According to this result, it has been concluded that the local farmers do not have enough information about Organic Agriculture, but the lack of information can be easily eliminated via TV-radio and the internet. As a result, it was concluded that Amasya farmers do not have sufficient information about Organic Agriculture production for now, but if appropriate training is provided, successful Organic Agriculture production output can be achieved.

2021
Selçuk Memiş
Self-Compacting Concrete (SCC) is a building material that has gained importance recently because it can easily and spontaneously settle in high buildings, where pouring conditions with frequent reinforcement are difficult. Agricultural structures, on the other hand, are structures that involve many units such as plant and animal barns, storage buildings and residences, and require care in their design and construction. In this study prepared for this purpose, it is used in concrete by replacing marble dust and fly ash with cement in concrete that will be used in agricultural structures. The main factor in these studies is to obtain information about the behavior of KYB with marble powder and fly ash, its fresh properties as well as its effect on durability, as well as to calculate the cost of marble powders in SCC with superplasticizers and similar chemical additives. Within the scope of the study, different ratios of marble powder (MP) and fly ash (FA) mixtures were created instead of OPC 32.5 and OPC 42.5. 100 mm cubic samples were prepared with the prepared mixtures and some of the physical properties of these samples were determined in 3th, 7th and 28th days. Samples were compared with SCC concrete values with traditionally produced references. As a result, it has been determined that the contribution of fly ash to SCC is more effective than the contribution of waste marble powder and can be used as powder material. In terms of cost, it has been observed that it will provide advantages in agricultural structures thanks to the high strengths obtained.

The belief that ancient wheat is more beneficial than common wheat has been growing trend in recent years among the consumers. The present study aims to compare bioactive peptide, allergen peptide and toxic peptide generation after gastrointestinal digestion of modern wheat (Triticum aestivum) and ancient wheat, einkorn (Triticum monococcum var. monococcum), using in silico tools. The primary sequences of both kinds of wheat were obtained from BIOPEP-UWM and UniProtKB/Swiss-Prot database. In silico digestion was applied using BIOPEP-UWM online tool. For the simulation of gastrointestinal digestion pepsin (pH 1.3) (EC 3.4.23.1), trypsin (EC 3.4.21.4), and chymotrypsin (EC 3.4.21.1) were selected and analyzed. Homology analysis was performed for each protein sequences using EMBOSS Needle program. Toxic and allergen peptides were predicted using ToxinPred online tool and Allergen FP v.1.0. The results showed that einkorn and common wheat proteins exhibited similar properties including high similarity rate (58.72-87.40%) indicating the percentage of matches between the two sequences and the identical bioactivities for peptides generated after digestion. Most of the bioactive peptides were dipeptides and the majority of them displayed more than one bioactivities including ACE inhibitory, DPP IV inhibitory or antioxidant activity, etc. Allergen peptides generated after in silico digestion were found to be similar for both kinds of wheat. In silico gastric digestion of einkorn and wheat caused toxic peptides production, but they were disappeared after in silico intestinal digestion. In conclusion, although there is a perception related to the Einkorn that is healthier than common wheat, in silico digestion of common wheat and einkorn did not support this perception.
