Pembelajaran merupakan instrumen penting mencerdaskan kehidupan Bangsa. Sebagai suatu sistem penting dalam pendidikan, pembelajaran diselenggarakan sebagai ruang interaksi terbangunnya relasi guru dan peserta didik mengembangkan potensi kognitif, psikomotorik dan afektif. Hal ini harus didukung dengan dinamika pembelajaran yang berjalan secara efektif dan suasana belajar internal yang membuat peserta didik tertarik belajar. Pembelajaran juga dapat dipengaruhi oleh faktor eksternal, seperti dengan adanya wabah Covid-19. Realitas menunjukkan bahwa dinamika pembelajaran di Indonesia saat ini terganggu oleh wabah Covid-19 yang memberikan dampak diantaranya; 1) sekolah dialihkan ke rumah melalui proses pembelajaran daring; 2) terjadi transformasi media pembelajaran berbasis teknologi melalui penggunaan Wathshap Group, Zoom, Google Classroom, WebEx, Youtube, dan saluran TV (TVRI); 3) penyesuaian metode pembelajaran; 4) penyesuaian evaluasi pembelajaran untuk penentuan standar kenaikan kelas dan kelulusan; dan 5) tuntutan kolaborasi orangtua peserta didik di rumah sebagai pengganti guru mengontro pembelajaran anak.

Published: July 2020

Comparative study on political attitudes between urban and rural communities has become a focus among scholars, especially after the results of 13th Malaysian general election. Nevertheless, studies on political attitude which focused on specific ethnic groups are still insufficient. This article aims to identify the political attitude of the urban Malays, especially in the context of political tolerance. This study discusses the political attitudes of urban Malays through quantitative research design which used questionnaire in three urban areas, namely, Johor Bahru, Shah Alam and Bukit Bendera. The findings summarized that Malay voters in urban areas are tolerant of political party’s differences and even an ethnicity is not a primary criteria of nominations in the elections. This study argues that urban Malays tend to tolerant of ethnic, religious or even liberal political party. Further analysis and recommendations are discussed.Keyword: ethnic tolerance, political tolerance, voting behaviour, modernization

Abstrak: Kajian perbandingan mengenai sikap politik antara masyarakat urban dan luar bandar telah menjadi fokus dalam kalangan sarjana, terutama selepas keputusan pilihan raya umum ke 13.Namun begitu, literasi kajian mengenai sikap politik yang tertumpu pada etnik yang spesifik masih lagi kurang. Artikel ini berhasrat mengenalpasti sikap politik urban Melayu, terutamanya dalam konteks toleransi politik. Kajian ini membincangkan mengenai sikap politik urban Melayu melalui rekabentuk kajian kuantitatif dengan instrumen soalselidik di tiga kawasan urban iaitu Johor Bahru, Shah Alam dan Bukit Bendera. Dapatan kajian merumuskan bahawa pengundi Melayu di kawasan urban terbuka dalam menerima perbezaan parti politik malah ukuran etnik bukanlah kriteria terhadap pencalonan dalam pilihan raya. Kajian ini menghujahkan kecenderungan pola sokongan parti politik kumpulan urban Melayu juga bersifat longgar dengan melepasi sempadan parti bersifat agama, etnik mahupun liberal. Analisa lanjut dan cadangan dibincangkan dalam artikel ini.Kata kunci: toleransi etnik, toleransi politik, kelakuan pengundi, modenisasi

Authors: Menni Younes , Chamkha Ali J. , Ameur Houari , Inc Mustafa
Published: July 2020

Improving the hydrodynamic characteristics of STHECs (Shell-and-Tube Heat Exchanger Channels) by using BVGs (Baffle-type Vortex Generators) is among the common passive methods due to their proved efficiency. In this computational investigation, the same method is used to enhance the hydrodynamic behavior of STHECs, by inserting W-shaped Baffle-type Vortex Generators. The numerical model represented by the computational FVM (Finite Volume Method) is used to simulate and analyzed the considered physical model. The fluid used is air, its thermal physical properties are constant, turbulent, incompressible, and its temperature is 300 K at the inlet section of the STHEC. The flow velocity ( Uin ) and atmospheric pressure ( Patm ) are considered as boundary conditions at the entrance (x = 0) and exit (x = L) of the channel, respectively. The results showed that the friction coefficients were related to the pressure, velocity, and Reynolds number values. High values of Re yielded an acceleration of the fluid, resulting thus in increased pressure on the solid walls and augmented friction values.

This study was conducted to evaluate the Kapotaksha River water pollution status and its impacts on Human health and Environment. This study conducted a case study on four selected areas (Barakpur, Srirampur, Prbazar, and Gouranandapur) on the Kapotaksha river bank at Jhikargas Upazila. This river water pollution occurs by some natural process such as flood, storm, and natural biodegraded. But human activities are major reasons for the river water pollution. Industrialization, urbanization, domestic waste, sewage system, agrochemicals, etc are major causes for river water pollution. This more polluted water has an impact on human health and environment. This study was conducted to find out the polluted water due to various types of diseases such as scabies, asthma, dysentery and respiratory disease. Most of the people (49%) are affected by Scabies, 4% are affected by diarrhea, 5% are affected by dysentery, 25% of people are suffering from respiratory diseases and 4% are suffering from asthma and the polluted water pollutes soil by using the water in agriculture purpose answered by 20% respondents which is 100% of farmer respondents. If someone does not use this water can not affect soil answered by 80% of respondents. This river water becomes more polluted and harmful for human health and environment because this water hampered by the local colony, local trader, lack of proper management of sewage system, miss-use on the riverbank area for the dumping various solid waste on the river bank, chemical fertilizers, industries etc. At present now we cannot fulfill control this continuous river water pollution but we can minimize this problem and it would be positive for human health, others living organisms and Environment.

Published: July 2020

The study was carried out to determine the economic assessment of lemon-based agroforestry systems established in the Madhupur Sal forest during the period from May 2017 to September 2018. The study selected five lemon-based agroforestry systems viz. Lemon-Mango-Pineapple-Papaya-Ginger, Lemon-Pineapple-Papaya-Banana-Aroid, Lemon-Pineapple-Papaya-Ginger, Lemon-Mango-Turmeric-Red amaranth and Lemon-Litchi-Papaya-Banana along with three replications having 0.13 ha area for each sample plot. The control plots (without lemon plant) for each of the five lemon-based agroforestry systems were also selected. In order to calculate the economic profitability of respective agroforestry systems as well as sole cropping performance, data related to incurred cost, total yield and income from lemon and crop components were collected through practical observation, key informant interview and focus group discussion. The benefit-cost ratio (BCR) and land equivalent ratio (LER) for each of the selected agroforestry systems were also determined. From the study, it has been found that all of the lemon-based agroforestry systems were profitable than their sole cropping in respect of income, BCR, and LER. The net profit (460032 Tk/ha) indicated that the Lemon-Litchi-Papaya-Banana based agroforestry systems were financially more profitable followed by Lemon-Pineapple-Papaya-Banana-Aroid, Lemon-Mango-Pineapple-Papaya-Ginger, Lemon-Pineapple-Papaya-Ginger, Lemon-Mango-Turmeric-Red amaranth based agroforestry systems. But the BCR and LER (3.515 and 1.73) revealed that Lemon-Pineapple-Papaya-Banana-Aroid based agroforestry system was more productive followed by Lemon-Litchi-Papaya-Banana, Lemon-Mango-Pineapple-Papaya-Ginger, Lemon-Pineapple-Papaya-Ginger, Lemon-Mango-Turmeric-Red amaranth based agroforestry systems. Prior to considering the obtained results from the study, it can be concluded that lemon-based agroforestry systems are more profitable than the cultivation of sole cropping.

Authors: Ali MM , Tarafder MMA , Mohsin N , Haque MA
Published: July 2020

A study was done for soil characterization and soil fertility assessment in Char Latif and Char Monpura of Bhola District to identify suitable crops for increasing cropping intensity and crop yields. The soils of Char Latif were almost silt loam to silty clay loam in texture. Soil pH values were slightly alkaline in reaction. The organic matter contents were low to medium (1.23-2.53%), the total N very low to low (0.08-0.22%), available P low to very low (4.67-14.1µg g-1 soil), available S  low to very high (4.02-156.8 µg g-1 soil) and exchangeable K low to optimum (0.138-0.311%), exchangeable Ca and Na very high in Char Latif areas. At Char Monpura areas, the soils were silt loam to silty clay loam in texture. The soil pH was neutral to slightly alkaline in reaction. The organic matter contents of the soil were low to medium (0.21-2.60%) and the total N contents were very low to low (0.03-0.18%). Available P contents were very low (2.40-6.65 µg g-1 soil). Available S contents were low to very high (4.02-156.8 µg g-1 soil). Exchangeable K, Ca and Na contents were medium to optimum (0.20-0.48 me%), in desired level (4.54-9.07me%) and very high level (1.64-5.14me%), respectively. The soils of both char land areas were normally erosive having low fertility and low water holding capacity. Generally, farmers of char lands cultivated local varieties of crops. As a result, crop yields are low. High yielding profitable crops and crop cultivation measures could be recommended for both of the Char Latif and Char Monpura areas. The findings could help the government and the other organizations to take proper steps for improving livelihood of the char peoples by improved crop varieties and management practices. Hence, there is great opportunity to increase crop production through intensification of crop cultivation with the selection of appropriate crop varieties and soil management at char lands.

Published: July 2020

Background and Objectives To investigate surgical outcomes of revision operation for recurrent cholesteatoma.Subjects and Method From 1989 to 2018, 5245 cases of middle ear surgeries were performed at Kangdong and Hallym University Sacred Heart Hospital. A total of 138 clinical records of the subjects who underwent revision cholesteatoma surgery, and whose follow-up durations were more than 3 months, were reviewed. Hearing outcomes were analyzed in accordance with the 2005 Korean otology society guideline. Postoperative perforation was defined to be present if perforation exists after three months of surgery. Postoperative infection or recurrence was defined if patients were treated with intravenous antibiotics or underwent reoperation.Results Among 138 cases, surgical approaches used were canal wall up mastoidectomy in 38 (28%), canal wall down mastoidectomy in 89 (64%), and exploratory tympanotomy in 11 (8%). Air conduction and air bone gap showed statistically significant differences before and after the surgery. The number of patients who met at least 1 criteria was 70, accounting for 51%. Patients were classified into four groups according to the Postoperative ABG grade, where 43% of patients were included in “Excellent” or “Good” results group. When the results were compared according to the surgical method, canal wall up group showed significantly higher hearing success rate compared to CWDM group. Patients without postoperative perforation, infection or recurrence were considered successful and there were 122 such cases, accounting for 88%.Conclusion CWDM more frequently underwent revision than CWUM and ET, and showed worse hearing results than other groups. These analyses can be used for preoperative counseling.

Authors: Noh Yangseop , Choi Ji-Eun , Lee Kyung Eun , Chung Seung-Kyu , Hong Sang Duk , Kim Hyo Yeol
Published: July 2020

Background and Objectives One of the most common surgical procedures in children is adenoidectomy, but the causes of adenoid hypertrophy are not fully understood. Some studies have found that allergies can be a risk factor for adenoid hypertrophy, asthma being one of these allergic diseases. This study aimed to investigate the relationship between adenoid size and asthma in a group of children.Subjects and Method This study reviewed a total of 2063 pediatric patients with or without atopy and asthma who visited the Otorhinolaryngology and Pediatric unit at a tertiary medical center from January 2011 to June 2016. We classified these patients into 4 groups according to the presence of asthma or atopy and randomly selected 100 patients from each group (to a total of 400 pts): group 1 (asthma-, atopy-); group 2 (asthma-, atopy+); group 3 (asthma+, atopy-) and group 4 (asthma+, atopy+). The presence of allergic sensitization (atopy) was evaluated by CAP test and total IgE. Asthma was diagnosed according to the diagnosis criteria in the Korean guideline for asthma. Adenoid size was evaluated with the adenoidal-nasopharyngeal ratio (A/N ratio) by the adenoid view.Results The four groups did not differ from each other significantly in age or sex. There was a negative correlation between adenoid size and atopic and asthmatic condition. Group 1 had a significantly larger A/N ratio than the other groups (group 1=0.534±0.138; group 2=0.469± 0.140; group 3=0.476±0.135; group 4=0.482±0.128, p<0.05). However, group 4 showed nearly identical results to groups 2 and 3, despite the combination of asthma and atopy in group 4.Conclusion Large adenoids were negatively associated with atopy and asthma. This finding may be explained by a decrease in adenoid stimulation by nasal obstruction and a difference in the immune system, including allergic immune reactions. Further studies are needed.

A Hebrew Exegesis Of Isaiah 62:1-5 The Restoration Of Zion
Authors: Chia Philip Suciadi , Juanda Juanda
Published: July 2020

In this study, spiritual, social-ethic and political background will be scrutinized to assist to understand Isaiah chapter 62 comprehensively. Spiritual life of God’s people is declined in the book of Isaiah because of idolatries and nations. Hebrew people make idols out of trees and worship pagan wooden idols (40:18-20; 44:9-20). Isaiah employs prophetic images for the covenant-breaking idolatry and worship of other gods by adultery and illicit sexual intercourse. It is clear that Isaiah is not exclusively interested in the interpersonal and social relationship structures within Israel. He is also concerned with the broader canvas of international politics.
Towards Cognitive Recommender Systems

Published: July 2020

Intelligence is the ability to learn from experience and use domain experts’ knowledge to adapt to new situations. In this context, an intelligent Recommender System should be able to learn from domain experts’ knowledge and experience, as it is vital to know the domain that the items will be recommended. Traditionally, Recommender Systems have been recognized as playlist generators for video/music services (e.g., Netflix and Spotify), e-commerce product recommenders (e.g., Amazon and eBay), or social content recommenders (e.g., Facebook and Twitter). However, Recommender Systems in modern enterprises are highly data-/knowledge-driven and may rely on users’ cognitive aspects such as personality, behavior, and attitude. In this paper, we survey and summarize previously published studies on Recommender Systems to help readers understand our method’s contributions to the field in this context. We discuss the current limitations of the state of the art approaches in Recommender Systems and the need for our new approach: A vision and a general framework for a new type of data-driven, knowledge-driven, and cognition-driven Recommender Systems, namely, Cognitive Recommender Systems. Cognitive Recommender Systems will be the new type of intelligent Recommender Systems that understand the user’s preferences, detect changes in user preferences over time, predict user’s unknown favorites, and explore adaptive mechanisms to enable intelligent actions within the compound and changing environments. We present a motivating scenario in banking and argue that existing Recommender Systems: (i) do not use domain experts’ knowledge to adapt to new situations; (ii) may not be able to predict the ratings or preferences a customer would give to a product (e.g., loan, deposit, or trust service); and (iii) do not support data capture and analytics around customers’ cognitive activities and use it to provide intelligent and time-aware recommendations.
A Practical Approach to Monitor Capacity under the CDM Approach
Authors: Zuniga Catya , Boosten Geert
Published: July 2020

The operations of take-off and landing at hub airports are often subject to a wide variety of delays; the effects of these delays impact not only the related stakeholders, such as aircraft operators, air-traffic control unity and ground handlers but as part of the European network, delays are propagated through the network. As a result, Airport Collaborative Decision Making (A-CDM) is being employed as a methodology for increasing the efficiency of Air Traffic Management (ATM), through the involvement of partners within the airports. Under CDM, there are some strategic common objectives regardless the airport or the partner specific interest to improve operational efficiency, predictability and punctuality to the ATM network and airport stakeholders. Monitoring and controlling some strategic areas such as, Efficiency, Capacity, Safety and Environment is needed to achieve the benefits. Therefore, the present work aims to provide a framework to monitor the accuracy of capacity in the three main flight phases. It aims to provide a comprehensible and practical approach to monitoring capacity by identifying and proposing Key Performance Indicators (KPIs) based on the A-CDM Milestone Approach to optimise the use of available capacity. To illustrate our approach, Amsterdam Airport Schiphol is used as case study as a full A-CDM airport.
Hybrid System Combining Ice-Phobic Coating and Electrothermal Heating for Wing Ice Protection
Authors: Morita Katsuaki , Kimura Shigeo , Sakaue Hirotaka
Published: July 2020

In-flight icing for aircraft is a large concern for all those involved in aircraft operations. Generally, an electric heater has been used to prevent in-flight icing. A hybrid anti-icing system combining ice-phobic coating and electrothermal heating (ICE-WIPS) has been proposed by the Japan Aerospace Exploration Agency (JAXA) to reduce the power consumption in the heating unit. In order to validate the effectiveness of ICE-WIPS, validation and demonstration tests are conducted using icing wind tunnels at the Kanagawa Institute of Technology (KAIT) and at the Icing Research Tunnel in the NASA Glenn Research Center. Using a NACA0012 airfoil as a test model, ICE-WIPS demonstrates substantial reduction in power consumption as compared to the existing heating system. The reduction depends on the in-flight icing conditions; more than a 70% reduction is achieved at a liquid-water content (LWC) of 0.6 g/m3 and a median-volume diameter (MVD) of 15 μm at 75 m/s with zero angle of attack. In wet-icing conditions, more than a 30% reduction in power is achieved.

The aims of this research were to evaluate the influence of intermittent microwave drying on the moisture diffusion and color qualities of organically and conventionally grown sweet red peppers and mathematically express drying kinetic data. Pepper samples of 150 g were dried at 150, 300 and 450 W using a microwave oven. Results showed that intermittent microwave drying at 450 W occurred mainly in the falling rate period, whereas drying at lower powers resulted in relatively longer constant rate periods for both peppers types. The Midilli model provided the best fit for all data. The moisture diffusivity (Deff) values of organic and conventional samples ranged from 59.69 × 10−10 to 182.01 × 10−10 m2s−1 and from 59.11 × 10−10 to 181.01 × 10−10 m2s−1, respectively, and the difference was insignificant. The pre-exponential factor for the Arrhenius equation (D0) and activation energy (Ea) values were almost identical for both product types. Overall, organic or conventional growing did not alter the structural features related to the heat transfer properties. Intermittent microwave drying at 150 and 300 W for organic peppers and 150 W for conventional peppers gave the highest ΔL*, Δa* and a*/b* values, producing the most bright and red pepper powders. Thus, these treatments can be used to produce higher color quality powders.

The problem of finding an optimal solution for the slurry application process is casted as a capacitated vehicle routing problem (CVRP) in which by considering the vehicle’s capacity, it is required to visit all the tracks only once to fully cover the field, as well as complying with a specified targeted application rate. A key objective in this study was to determine an optimized coverage plan in order to minimize the driving distance in the field, while at the same time allowing for varying the application rate. The coverage plan includes the optimal sequence of tracks with a specified application rate for each track. Two algorithms were developed for optimization and simulation of the slurry application cast as capacitated operations. In order to validate the proposed algorithms, a slurry application operation was recorded, and the results of the optimization algorithm were compared with the conventional non-optimized method. The comparison showed that applying the proposed new method reduces the non-working distance by 18.6% and the non-working time by 28.1%.

The cultivation of perennial grasses is one of the most desirable alternatives as energy feedstock, but it is difficult to achieve competitive yields under Mediterranean marginal conditions. The aim of this study was to assess the performance of three cool-season grasses (Agropyron spp.) from an agronomic and energetic point of view by comparing the dry matter (DM) yields, rain use efficiency, chemical composition, and biomass quality over an eight-year period in Spain under marginal rainfed conditions. The tall wheatgrass (Agropyron elongatum (Host) Beauv.) cultivars, Alkar (4.8 Mg DM·ha−1) and Jose (4.7 Mg DM·ha−1), achieved the highest yields. Productions below 0.5 Mg DM·ha−1 were obtained when rainfall was lower than 150 mm between March and June. The biomass obtained from the tested grasses showed relatively high contents of ash, silicon, and alkali elements. Net calorific values ranged between 16.7 and 18.5 MJ·kg−1 db. Differences in the composition among species and cultivars are not likely to affect their combustion behavior from a practical point of view. The ash content, as well as the concentrations of K, S, Na, and Cl, tended to decrease over the years. The results offered would be very useful for the implementation of this type of crop in marginal land.

Climate change forecasts suggest temperature increases and lower rainfall rates, both of which challenge viticulture, particularly in semi-arid areas where water availability is critical. In this scenario, the use of the genetic variability in grapevine varieties reported around the world represents an important strategy for the selection of climate-resilient cultivars. In this work, physiological and metabolomics analyses were conducted to compare the water deficit stress (WDS) responses of red and white, local and widespread grapevines cultivars. Leaf gas exchange, water use efficiency (WUE) and water relation parameters were determined in plants under well-watered and WDS conditions alongside assessment of the levels of foliar primary metabolites using gas-chromatography coupled to mass-spectrometry. Results denote that red and white local cultivars displayed more adapted physiological performance under WDS as compared to the widely-distributed ones. Multivariate analyses and specific changes in leaf primary metabolites indicate genotype-specific responses of local cultivars as compared to widespread ones. Differences in ascorbate-related and shikimate/phenylpropanoid metabolism could explain the better physiological performance under WDS in red local as compared to widespread cultivars. On the other hand, coordinated changes in respiratory- and stress-related sugars and amino acids could underlie the better WUE under WDS in the white local cultivar. All these results suggest several metabolic targets that could be useful as metabolic markers or for metabolic engineering in grapevine breeding programs to improve drought tolerance.

Olive fruit fly Dacus oleae is a well-known pest infecting the bark of olive fruit, leading to reduction of extracted olive oil properties. Among chemicals proposed for Dacus oleae population control, pheromone 1,7-dioxaspiro(5.5)undecane (DSU), Dacus pheromone, is considered as a promising agent, which is added in several traps. However, all proposed systems manage to sufficiently deliver DSU for only two weeks. Furthermore, an additional problem is the limited available amount of pheromone to use in such systems. To overcome this, in the present study, a novel synthetic procedure of DSU is described, including only five steps. Intermediate products were studied by High Resolution Mass Spectroscopy Electrospray Ionization (HRMS-ESI) (m/z), while the resulting DSU was further characterized by 1H and 13C-NMR. Synthesized DSU was further encapsulated in poly(L-lactic acid) (PLLA) microparticles in three different concentrations; 5, 10 and 20% w/w. Its successful incorporation was studied by FT-IR, XRD and differential scanning calorimeter (DSC) while two procedures, liquid extraction and solid phase microextraction, followed by GC-MS analysis, was used for quantification of pheromone to microparticles. It was found that microparticles loading was over 85% for all three formulations. Its release showed a prolonged profile for microparticles containing 20% w/w DSU, lasting four weeks, while the quantity of DSU released reached 100%. These microparticles could be appropriate to control Dacus oleae population.

Cropping systems are structured to maximize crop yields and increase sustainability in agricultural production. A field study was conducted to investigate different long-term cropping systems on soil organic matter and microbial communities. The cropping systems studied were: (i) a 14-year continuous alfalfa (Medicago sativa L.) (CA), (ii) a 9-year alfalfa removed and rotated with 4–5 years continuous annual crops (spring wheat (Triticum aestivum L.), maize (Zea mays L.), potato (Solanum tuberosum L.), and millet (Panicum miliaceum L.)), and (iii) a 5-year field fallow after alfalfa. Results showed that continued annual crops decreased total organic C and labile organic C by 10 to 20% and 17 to 34% in the topsoil (0–30 cm), and by 15 to 35% and 20 to 46% in the subsoil (30–60 cm), respectively, compared with CA. Similar trends were found in soil total N concentration, which decreased by 7 to 20% in the topsoil. Highest microbial biomass C was found in CA. Shannon-Wiener diversity and substrate richness of soil microbes measured by Biolog EcoPlates was significantly affected by cropping system with CA exhibiting a higher degree of soil microbial functional diversity in the topsoil, while the lowest values were found in the alfalfa-potato system. The higher soil organic matter content and functional diversity of soil microbe in CA indicates that soil nutrition and microbial activity did not limit alfalfa development and growth in the dryland area. The lower microbial activity and functional diversity observed in the potato field indicates the importance of crop selection in cropping systems.

E. colona is a C4 annual summer grass which is troublesome to major summer annual and perennial crops. Due to recent complaints by the farmers, the objectives of the present study were to evaluate the efficacy of penoxsulam, profoxydim, cycloxydim, cyhalofop-butyl, florpyrauxifen-benzyl and glyphosate against six E. colona accessions, and also to evaluate the response of these accessions to different rates of glyphosate in a dose-response experiment. In the first experiment, herbicides were applied at their maximum recommended label rates, while in the dose-response experiment, glyphosate was applied at six doses corresponding to 0, 1/4X, 1/2X, X, 2X, and 4X of the recommended rate. The dry weight of the biotypes TH8 and TH7 treated with profoxydim was 66% and 68% of the untreated control, respectively. The efficacy of cyhalofop-butyl against three accessions was lower than 30%, while two accessions were susceptible to this herbicide. The efficacy of penoxsulam against the biotypes ET2 and ET4 was lower than 10%, while dry weight of FT5 and TH8 was only reduced by 23%–28% as compared to the control. Cycloxydim application provided control higher than 75% at 21 days after treatment (DAT) of three accessions, while the majority of E. colona accessions was adequately controlled by the application of florpyrauxifen-benzyl. The response of the different accessions to glyphosate varied. The results of the glyphosate dose-response experiment revealed that the GR50 values of the resistant E. colona accessions ET2 and ET4 were up to 1098 and 1220 g a.e. ha−1 of glyphosate, respectively, whereas the GR50 value of the susceptible accession (FT5) was only 98 g a.e. ha−1. The resistance indices of ET2 and ET4 were 12.4 and 11.2, respectively, indicating that they have already developed resistance to glyphosate. Three more accessions could be also of developing resistant to glyphosate. This is the first report of glyphosate resistance from E. colona accessions in Greece, with indications of multiple resistance also present. Further research is needed in order to evaluate the efficacy of several herbicides under different soil and climatic conditions, conduct baseline sensitivity studies, reveal the evolvement of resistance patterns to glyphosate from accessions of Echinochloa spp., and search for alternative options of weed management in annual and perennial crops due to the clear indications of multiple resistance situations.
