A greenhouse pot experiment was conducted in the Agricultural University of Athens in order to evaluate the effect of several greenhouse cover materials on the performance and yield of hemp. The experiment was set up in a completely randomized design (CRD) with five treatments/greenhouses (G1, G2, G3, G4/Control, and G5). Measurements included plant height, PAR (Photosynthetic Active Radiation), chlorophyll content, solar irradiance, soil and leaf temperature, and yield components (the number of buds, their weight, length, and compact index, CBD content, and CBD yield per plant). The results of the present study suggest that the different polyethylene cover films alter the environment within the greenhouse and thus, affect the agronomic characteristics and yield traits of hemp. G1 reported the best results as it increased soil temperature and PAR values by 11-16% and 50-110% respectively, compared to G4. Concurrently, the majority of the bud characteristics were significantly improved in G1. Even though further research should be conducted in order to define the most suitable films for greenhouse hemp production, our results indicate that the optical properties of the greenhouse cover materials affect its yield and should always be considered.

A greenhouse pot experiment was conducted in Western Greece in order to evaluate the effect of different nitrogen rates on the development of the root system and productivity of chia (Salvia hispanica L.) plant. The experiment followed a completely randomized design (CRD), with six treatments, different rates of applied nitrogen (0, 25, 50, 75, 100 and 125 kg ha-1 equivalent to 0, 134, 268, 402, 536 and 670 mg nitrogen pot-1). The results of this study showed that root length density (RLD) and root mass density (RMD) increased with the increased rate of applied nitrogen and the highest values (1.297 cm cm-3 and 1.178 mg cm-3, respectively) were found after the application of 670 mg nitrogen pot-1 at 100 days after sowing (DAS). Plant height (106.06 cm) and leaf area per plant (883.14 cm2) were significantly affected by the highest rate of nitrogen. Additionally, dry matter and seed yield per plant were clearly affected by fertilization, with the highest values (27.57 g and 4.20 g, respectively) obtained in plants treated with 670 mg nitrogen pot-1. In conclusion, increasing the levels of applied nitrogen up to 670 mg N pot-1 improves root development and therefore the yields of chia.
在希腊西部进行了温室盆栽试验，研究了不同施氮量对鼠黄草根系发育和生产力的影响。试验采用完全随机设计(CRD)，共设6个处理，施氮量分别为0、25、50、75、100和125 kg ha-1，相当于0、134、268、402、536和670 mg氮肥。结果表明:根长密度(RLD)和根质量密度(RMD)随施氮量的增加而增加，在播后100 d (DAS)施氮670 mg，根长密度(RLD)和根质量密度(RMD)最高，分别为1.297 cm cm-3和1.178 mg cm-3。最高施氮量对株高(106.06 cm)和单株叶面积(883.14 cm2)有显著影响。单株干物质和单株种子产量受施肥影响明显，以670 mg氮肥1处理植株的干物质和单株种子产量最高，分别为27.57 g和4.20 g。综上所述，将施氮量增加至670 mg N -1，可促进根发育，从而提高产量。

Brassicaceae family is an important one since it includes many economic and significant industrial oilseeds, spices, vegetables and some forage plants. In this study, sequences analysis among Chrysochamela (Brassicaceae) species distributed in Turkey were conducted nrDNA ITS and cpDNA trnL intron sequences. Chrysochamela species were collected and brought to the laboratory. ITS and trnL intron sequences were corrected with BioEdit and FinchTV programs. As a result of the study, ITS nucleotide compound compositions were determined as 22.7% T, 29.1 C, 21.5% A and 26.7% G. The lowest distance was 0.000 and the highest distance was 0.037. The phylogenetic tree obtained using the MEGA 6.0 program consists of two large groups. According to trnL intron sequences 37.9% T, 18.4 C, 28.3% A and 15.5% G. Nucleotide compound compositions were determined. The genetic distance between species was determined between 0.000 and 0.022. Maximum likelihood phylogenetic tree consists of two large groups. As a result, phylogenetic analyzes using ITS and trnL intron sequences were compatible with each other. It was also in past studies found to be supported by morphological, anatomical and RAPD data.

The field of constructions has evolved extraordinarily in terms of measurement techniques, requiring increasing accuracy. This has led to the creation of new specific technologies, and implicitly measuring instruments. The range of classical geodetic measuring instruments has been completed with new high precision instruments, even in the field of physics or machine building. The use of geodetic measurement methods in the field of Engineering Topographic Measurement Techniques involves, in addition to ensuring precision requirements, the choice of appropriate devices and technologies. This choice is imposed both by the previous precision calculations, starting from a maximum permissible deviation given, and by the knowledge of the execution and assembly technologies. The purpose of this paper was to study the effect and also the impact that new technologies had on the main measurement activities, and of course on measurement techniques. This review article summarizes, analyzes and discusses the current state of primary research in terms of the impact of current or developing technologies on geodetic techniques. The global corpus of primary research is growing at an unprecedented rate. It is difficult for most researchers to grasp the state of the art of a topic. A vast number of bibliographic references were taken into account, on which analyzes were performed.

Authenticity, certification, and especially the origin of food has become an increasing priority among consumers and producers, in the case of wines, this is very important especially if commercial values are associated with the region of production. In the last decades, isotopic ratios of geological interest, such as Pb, and Sr, have gained interest in the tracking regional provenance of foods and especially of wine. The correlation of the Pb and Sr isotope ratios between soil and plant makes it an interesting tool for tracing the provenance of agricultural products such as grapes and wine. The purpose of this research was to assessment the Pb and Sr isotopic ratio to highlight geographical markers with a high degree of credibility in several Romanian wine-growing areas. The values of the 206Pb/207Pb, for the vine from Dealu Bujorului and Valea Călugărească vineyard show traces of lead atmospheric pollution, in Nicorești, Panciu, and Ștefăneți-Argeș vineyard the values of the isotopic ratio show traces of fly ashes, coals, or natural Pb and Greaca vineyard show traces of petrol, gasoline, combustion. Due to Pb, and Sr a separation on the vineyards and wine-growing centers, and also a separation of the wine samples was possible.

Cotton is a plant, which is mainly cultivated in regions where the irrigation is necessary as rainwater is not adequate. Researches in the recent years have showed that the irrigation water used could be declined. Improvements in the technological field has made Decision Support Systems combined with Neural Networks and data analysis, an important tool of sustainable agriculture. Cotton producers need to reduce irrigation water needs and that can be achieved by using new technologies. The development Decision Support System was conducted, having 3 different types of input. Data derived from a variety of IoT sensors, weather stations, and on-site measurements (yield and ΕΜ38) derived from 3 fields in Greece, creating a dataset of 9 different inputs. A total of 13 different algorithms were tested and evaluated in order to determine which one is the ideal for our dataset. The adoption of this technology in real data predicted the reduction of the irrigation times, ensuring that there will be no losses in the final yield.

Temporary Immersion Bioreactor (TIB) is a suitable technique for large scale micropropagation of plant species. The aim of this work was to test the capacity of in vitro proliferation of the primocane-fruiting red raspberry cv Maravilla and floricane-fruiting red raspberry cv Willamette on gelled media compared to liquid media. The two varieties were cultured in vitro on two media, Murashige and Skoog 1962 (MS) and Driver and Kuniyuki walnut medium, 1984 (DKW), both supplemented with 0.5 mg/l 6-benzyladenine (BA). In the control cultures on gelled media the media were gelled with 5g/l Plant Agar, whereas for the cultures in liquid media Plantform bioreactors were used. After six weeks of in vitro culture we recorded the proliferation rates and lengths of the axillary shoots obtained in all the experimental treatments. The highest proliferation rate was 16 ± 2.03, obtained in cv. Willamette on gelled MS medium with 0.5 mg/l BA. The longest shoots (3.17 ± 0.32 cm) were obtained at cv. Maravilla on the DKW medium with 0.5 mg / l BA in the bioreactor. Our research highlighted that Rubus idaeus L. Maravilla and Willamette can be TIB propagated, although further research is needed to improve the efficiency of this method.

Tomato is one of the most significant vegetables in the world. Specifically, for the industrial tomato cultivation, the product is harvested when °Brix are at their peak. Technological advancements nowadays have made Decision Support Systems, based on Machine Learning Algorithms more applicable in a daily basis. Sustainable agriculture is evolving since farmers could be advised by this technology in order to take the best decision for their crops. Farmers who adopt this kind of technology will be able to know the quality of tomatoes. The implementation of a Decision Support System capable to predict the °Brix was conducted, based on various data from previous years, such as quality characteristics, the tomato hybrid used, weather conditions and soil data from the selected fields. Data came from fields from 6 different regions in Peloponnese, Greece over 3 cultivation periods. 12 different algorithms were tested in order to find which is the best one in terms of efficiency. Results of this research showed that the predicted °Brix were following the same pattern as the actual °Brix. This means that the DSS could advise the farmer about the ideal harvesting period where the °Brix will be maximized. The use of this DSS using real time weather data as an input will be a valuable tool for the farmers.

The use of this DSS using real time weather data as an input will be a valuable tool for the farmers.","PeriodicalId":9406,"journal":{"name":"Bulletin of University of Agricultural Sciences and Veterinary Medicine Cluj-Napoca: Horticulture","volume":"94 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85700932","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While English for Specific Purposes has been dealt with by researchers all over the world, the insertion of educational technology and online environment is a relatively new concept. This article explores the main aspects of an effective online ESP learning process during the 2019-2020 academic year within the split frame generated by the pandemic context. It also aims at setting the educational frame for the future of ESP classes from the standpoint of the freshmen of Agricultural Sciences. An online questionnaire was answered, its structure being underlined by aspects such as content and skill-related tasks, accessibility, motivation, engagement, educational environment, media and assessment. The use of specialization-related materials is positively adjusted towards the online ESP classes, whereas frequency usage of skill-related tasks shows more balanced values between on-site and online ESP classes. In terms of schedule flexibility, the online medium is the more manageable of the two. If the combination of online exercises, specialized sites, online apps and platforms is clearly the norm for the online ESP classes, on-site assessment is evaluated as being more accurate. Although the students’ answers are relatively balanced, the majority agreed that the online environment is the most suitable frame for the future ESP classes.

In a world threatened by increasing perceived corruption, its effects upon the health of nations have been scarcely studied, in spite of the tremendous importance sustained health has held on the European agenda. The purpose of this paper is to determine the impact of corruption upon health outcomes within an environmental performant and urbanised setting. The determinants of health outcomes measured as wellbeing, life expectancy and under-5 child mortality rate are estimated on an unbalanced panel data set covering the 2005–2020-time interval for the 27 member states of the European Union. The resulting econometric models validate the significance of corruption, environmental performance and urbanisation upon health outcomes: subjectively perceived corruption hampers the development of nations’ health while a clean environment with an increasing tendency of urbanisation has a positive impact upon the health outcomes of European nations. This study also sketches important policy implications for improving the health status of European countries.
