The use of antibiotics is a major problem everywhere around the globe and in step with this, there's currently an increased public and scientific interest. Microbial resistance is a vital issue for the organizations like EFSA, WHO, FDA, and FAO because it is developing rapidly and is an increasingly serious health concern within the world. Microbial resistance comes as a result of continuous exposure of microorganisms to antibiotics. Lactic acid bacteria (LAB) constitute a really important group of microorganisms that can inhabit different conditions and environments, as the different parts of the gastrointestinal tract of humans and animals, and are an important element of the microbiota of fermented foods. The FDA and EFSA authorities have given them the status referred to as GRAS (Generally Recognized as Safe) and QPS (Qualified Presumption of Safety). Continuous exposure of LAB to environments with antibiotics may prompt them to become an intrinsic or extrinsic reservoir of genes accountable for antibiotic resistance. Knowledge of antibiotic susceptibility of bacteria with probiotic potential is important. Also, it's essential to define their resistance profile. Ten newly isolated strains from traditional fermented foods were used for determining the antibiotic resistance profile. The resistance to antibiotics varied among the examined strains and a few of the antibiotics resulted in complete resistance. Chromosomal DNA of LAB was analyzed for the antibiotic resistance genes. Only five of eight vancomycin-resistant strains have shown that they contain the resistance gene in chromosomal DNA. None of the genes that determined the resistance to other antibiotics have been detected in chromosomal DNA.

Tomato crop occupies a predominant place after that of potatoes in market garden crops in Algeria. The main purposes of this study were to evaluate crop performances, variability of some morphologic and phenologic traits, and correlations with the yield of seven (07) genotypes of tomato. The trials were carried out on Random Complete Blocs Design (RCBD) with three replications at the local unheated greenhouse during the period from November to June 2018. The most important morphological markers used were stem growth rate, inflorescence (Number of flowers, length of peduncle) and fruit characters (length and circumstance), phenologic stages, and average yield. The effect of the genetic material on the observed variability was significant for all the traits considered. Additionally, we noticed positive values of correlation coefficients of yield with stem length between every two clusters and the number of leave under cluster, average fruit weight, and earliness to flowering. Additionally, earliness to flowering shows very high and stable correlations (above 0.8) with yield during the crop cycle. The principal component analysis showed that the first two components generated 62.17 % of variability, while the first four components accumulated more than 93 % (93.51 %) of the total diversity. Moreover, the dendrogram analysis classified the genotypes within 03 groups.

In agricultural production, fertilization has become mandatory for improving the soil and increasing the yield of the product. Especially in the production of horticultural crops, the need for precise and detailed fertilization management complicates the production. Intensive long-term use of conventional fertilizers causes serious environmental problems such as groundwater pollution, deterioration of soil quality and air pollution. This has led to the search for particularly effective and environmentally friendly fertilizers. Recently, nano-fertilizers are considered as a promising fertilization alternative. Nano-fertilizers benefit nutrition management due to their strong potential to increase nutrient utilization efficiency. The present study aimed to determine the effect of silver nanoparticles (AgNPs) on some growth parameters of radish grown under deficit irrigation conditions. For this purpose, in this study, four different irrigation water levels (I0; 100% full irrigation, I1; 20% deficit irrigation, I2; 40% deficit irrigation and I3; 60% deficit irrigation) and four different nanosilver doses (Ag0: 0 ppm, control; Ag1: 20 ppm; Ag2: 40 ppm and Ag3: 80 ppm) were applied. The study was carried out in a total of 48 pots in three replications according to the randomized plots experimental design under greenhouse conditions. The findings showed that root length, root diameter, root fresh weight and root dry weight significantly (p<0.01) decreased in deficit irrigation. While root parameters were significantly increased in Ag nanoparticle applications, the number of leaves were not varied statistically. The highest root height (33.21 mm) was determined in full irrigation application with Ag3 (80 ppm). As a result, it can be stated that radish plant growth in silver nanoparticles can be significantly improved under deficit irrigation conditions compared to control application non-silver nanoparticles.

Forest crops (nurseries and plantations) impose difficulties on foresters, the main cause being disturbing or harmful factors that compete and interact in different directions, but whose result is the weakening of seedlings, culminating in their death. Given that the number of seedlings in nurseries and plantations is high compared to the unit area, the risk of disease and pest attacks is very high. For this reason, it is necessary to monitor the annual forest crops, both in terms of biological material and soil, in order to control or eliminate possible sources of infestation. In order to achieve the proposed objectives, ash, maple and lime seeds were harvested from Mihai Viteazu Nursery, spruce seeds from Voivodeni Nursery, Forest district Someșu Rece, Forest district Beliș and larch from Forest district Beliș. Specific phytopathological analyzes of the seed samples were performed on the seeds in order to accurately determine the possible pathogens. In the analyzes, the pathogens Fusarium oxysporum, Alternaria alternata and Botrytis cinerea were identified on both deciduous and coniferous seeds.

In recent years, with the effect of the climate analysis and weather forecasting are accepted as one of the most important natural topics. Adana, located in the Mediterranean region, has a Mediterranean climate and is one of Turkey's roughest cities. Because of its Mediterranean climate, different weather conditions are observed in every season of the year in Adana. In this study, it is aimed to make a monthly average weather forecast for the next 12 months in Adana. The dataset used in this study was collected from two different weather websites since January 2019 and includes Adana's daily weather values including maximum temperature, minimum temperature, humidity, and wind speed. Weather forecasting was performed on this dataset using linear regression method with Weka data mining tool. While predicting the weather using the linear regression method, it is provided that the relationship between the variables was calculated, and an equation between them was established to make predictions. According to the results obtained, it has been observed that good results cannot be obtained when day-based forecasting is requested, but almost the same results are obtained when the monthly average are requested. In addition, the results of the estimations were approximate, and as a result of the study, the Correlation Coefficient was found to be 0.9832.Additionally, it was concluded that while forecasting the weather, linear regression, which is a data mining technique, yields positive results when the forecast is made with the monthly average.

The paper focuses on the obtaining biotechnology and in vitro propagation of edible and/or medicinal macromycetes mycelia from the genus Pleurotus in submerged cultures in order to produce the biological “seeding” material - spawn. The quality and biological purity of the spawn is critical to the success of mushroom production and productivity. Starting from stock cultures from the collection of the RDIVFG Vidra, the mother cultures were obtained, the biological material being represented by two strains of Pleurotus ostreatus and one strain of Pleurotus citrinopileatus, each of them being cultivated in PDB + K2HPO4 (1,5g/l), pH 6.5 medium at different stirring speeds (0/100/150 rpm). The submerged growing biomass was used to inoculate wheat caryopsis, that evolved into spawn after complete colonization. The lignocellulosic substrate was obtained from wheat straws with the addition of nutritional supplements (wheat and maize bran and sunflower middlings) and distributed in the polypropylene bags. Their yielding capacity was verified in the fruiting chamber of the laboratory micro-mushroom farm test facility.

Drying is one of the most effective preservation methods applied to increase the shelf life of agricultural products. In this study, the effect of different pre-treatments on drying dragon fruit with a microwave was investigated. It is also aimed to determine the drying method with the minimum energy consumption. Dragon fruit slices were dried by microwave at 300 W output power in four different pretreatments as ultrasound, gum arabic, sucrose, and without pretreatment. Pretreatment applications were carried out by performing ultrasound for 10 minutes on dragon fruit slices and soaking them in 10% gum arabic and sucrose solutions before drying. Results showed that the shortest and longest drying times were measured in gum arabic and without pretreatment, respectively. Time-dependent estimation data were calculated by six different thin-layer drying models, considering the drying times and moisture rates. Jena&Das model showed the best fitting performance. As a result, it has been determined that pretreatment applications reduce drying time and energy consumption. In addition, gum arabic pre-treatment is advantageous in terms of energy consumption in microwave drying of dragon fruit.

The genus Festuca L. is a genus of flowering plants belonging to the grass family Poaceae, being one of the largest in Gramineae with ±450 species in temperate and alpine regions of both hemispheres with a cosmopolitan distribution occurring on every continent except Antarctica. They are evergreen or herbaceous perennial tufted grasses with a height range of 10–200 cm. The specimens of Festuca are preserved in the Al Beldie Herbarium from INCDS Marin Drăcea Bucharest. This Herbarium hosted 309 vouchers with 52 Festuca species, most of them belonging to F. gigantea (28), F. versicolor (27) and F. arundinacea (22). The oldest specimens were collected in 1773 and 1788. Most of the herbarium specimens were generally in very good (198) and good (76) condition except for a smaller number of specimens which were damaged (35). The aim of this article is to describe some Festuca species which are very good preserved.

The nutrition regime for tomatoes is very complex and must consider the specific consumption that differs depending on the variety, vegetation phase, cropping system and others. The super-intensive character of the protected and forced vegetable crops determines a special specificity regarding the requirements towards the soil and its state of supply with nutrients. Vermicompost, also known under the name of earthworm humus, is an organic fertilizer that is produced utilizing the assistance of earthworms. Vermicompost can completely replace any other chemical or even organic fertilizer, as it contains, up to 100 times more nutrients and microorganisms that are beneficial for plants. The researches have been carried out since 2020 in Matca, Galati County and aimed at producing vermicompost and testing it on different crops in protected areas. Tomatoes - Yigido F1 is a hybrid of semi-early tomatoes, with undetermined growth, intended for cultivation in protected areas. There were made determinations on tomatoes culture regarding the influence of vermicompost on the development of plants and quality of tomatoes.
