Published: July 2023

Abstract. The chronology of the Cenozoic, so called ‘Namib Group’ of the Namib Desert is rather poor in terms of direct radiometric dating. Most of the chronological information is based on the ostrich shell biochronostratigraphy. The widespread occurrence of calcretes and silcretes in the Namib Desert makes it possible to date important phases of landscape stability and to retrieve critical paleoclimatic and -environmental information on desertification and its paleoclimatic variability. The application of the U-Pb laser ablation dating technique to Plio/Pleistocene sil- and calcretes provides critical insights into groundwater calcrete formation and climate variability in the Central Namib. Microscale silcrete formation due to pressure solution by expanding calcrete cementation provides the opportunity to date multiple phases (multiple generation of silcrete as growing layers or shells) of silcrete formation and to trace their paleoclimatic and -environmental fingerprints. Groundwater sil- and calcrete formation occurred during the Pliocene. TCN exposure ages from flat canyon rim surfaces indicate the cessation of groundwater calcrete formation due to incision during the Late Pliocene/Early Pleistocene and mark a large-scale landscape rejuvenation due to climate shifts towards the Pleistocene. This study demonstrates the application of U-Pb laser ablation to groundwater sil- and calcretes in desert environments and opens up the possibility of dating numerous sedimentary sequences containing sil- and calcretes in arid environments. In particular, the use of silcretes (as described above) reduces potential effects of detrital components and bulk-signal measurements by using massive calcretes. Our study redefines and improves the generally accepted Late Cenozoic chronostratigraphy of the Namib Desert (Miller, 2008).

Abstract. This study analyzes the quality of simulated historical precipitation across the contiguous United States (CONUS) in a 12 km Weather Research and Forecasting model version 4.2.1 (WRF v 4.2.1)-based dynamical downscaling of the fifth-generation ECMWF atmospheric reanalysis (ERA5). This work addresses the following questions. First, how well are the 3 and 24 h precipitation characteristics (diurnal and annual cycles, precipitation frequency, annual and seasonal mean and maximum precipitation, and distribution of seasonal maximum precipitation) represented in the downscaled simulation, compared to ERA5? And second, how does the performance of the simulated WRF precipitation vary across seasons, regions, and timescales? Performance is measured against the National Centers for Environmental Prediction/Environmental Modeling Center (NCEP/EMC) 4 km Stage IV and Oregon State University Parameter-Elevation Regressions on Independent Slopes Model (PRISM) data on 3 and 24 h timescales, respectively. Our analysis suggests that the 12 km WRF exhibits biases typically found in other WRF simulations, including those at convection-permitting scales. In particular, WRF simulates both the timing and magnitude of the summer diurnal precipitation peak as well as ERA5 over most of the CONUS, except for a delayed diurnal peak over the Great Plains. As compared to ERA5, both the month and the magnitude of the precipitation peak annual cycle are remarkably improved in the downscaled WRF simulation. WRF slightly overestimates 3 and 24 h precipitation maximum over the CONUS, in contrast to ERA5, which generally underestimates these quantities mainly over the eastern half of the CONUS. Notably, WRF better captures the probability density distribution (PDF) of 3 and 24 h annual and seasonal maximum precipitation. WRF exhibits seasonally dependent precipitation biases across the CONUS, while ERA5's biases are relatively consistent year round over most of the CONUS. These results suggest that dynamical downscaling to a higher resolution improves upon some precipitation metrics but is susceptible to common regional climate model biases. Consequently, if used as input data for domain-specific models, we suggest moderate bias correction be applied to the dynamically downscaled product.

Abstract. The climate impact of non-CO2 emissions, which are responsible for two-thirds of aviation radiative forcing, highly depends on the atmospheric chemistry and weather conditions. Hence, by planning aircraft trajectories to reroute areas where the non-CO2 climate impacts are strongly enhanced, called climate-sensitive regions, there is a potential to reduce aviation-induced non-CO2 climate effects. Weather forecast is inevitably uncertain, which can lead to unreliable determination of climate-sensitive regions and aircraft dynamical behavior and, consequently, inefficient trajectories. In this study, we propose robust climate-optimal aircraft trajectory planning within the currently structured airspace considering uncertainties in standard weather forecasts. The ensemble prediction system is employed to characterize uncertainty in the weather forecast, and climate-sensitive regions are quantified using the prototype algorithmic climate change functions. As the optimization problem is constrained by the structure of airspace, it is associated with hybrid decision spaces. To account for discrete and continuous decision variables in an integrated and more efficient manner, the optimization is conducted on the space of probability distributions defined over flight plans instead of directly searching for the optimal profile. A heuristic algorithm based on the augmented random search is employed and implemented on graphics processing units to solve the proposed stochastic optimization computationally fast. An open-source Python library called ROOST (V1.0) is developed based on the aircraft trajectory optimization technique.
The effectiveness of our proposed strategy to plan robust climate-optimal trajectories within the structured airspace is analyzed through two scenarios: a scenario with a large contrail climate impact and a scenario with no formation of persistent contrails. It is shown that, for a nighttime flight from Frankfurt to Kyiv, a 55 % reduction in climate impact can be achieved at the expense of a 4 % increase in the operating cost.

Published: July 2023

Abstract. Exploring the snow depth on Mount Everest, one of the most inaccessible places on our planet, has long been a
topic of interest. Previously
reported snow depths have been inconsistent and have large uncertainties.
Here, we report the ground-penetrating radar survey of snow depth along the
north slope of Mount Everest in May 2022. Our radar measurements display
a gradual increasing transition of snow depth along the north slope, and the
mean depth estimates at the summit are 9.5±1.2 m. This updated snow
depth on Mount Everest is much deeper than previously reported values
(0.9–3.5 m).
Uncertainty growth and forecast reliability during extratropical cyclogenesis
Authors: Rodwell Mark J. , Wernli Heini
Published: July 2023

Abstract. In global numerical weather prediction, the strongest contribution to ensemble variance growth over the first few days is at synoptic scales. Hence it is particularly important to ensure that this synoptic-scale variance is reliable. Here we focus on wintertime synoptic-scale growth in the North Atlantic storm track. In the 12 h background forecasts of the Ensemble of Data Assimilations (EDA) from the European Centre for
Medium-Range Weather Forecasts (ECMWF), we find that initial variance growth at synoptic scales tends to be organized in particular flow situations, such as during the deepening of cyclones (cyclogenesis). Both baroclinic and diabatic aspects may be involved in the overall growth rate. However, evaluation of reliability through use of an extended error–spread equation indicates that the ECMWF ensemble forecast, which is initialized from the EDA but with additional singular vector perturbations, appears to have too much variance at a lead time of 2 d and that this over-spread is associated with cyclogenesis situations. Comparison of variance growth rates and reliability with other forecast systems within The International Grand Global Ensemble (TIGGE) archive indicates some sensitivity to the model or its initialization. For the ECMWF ensemble forecast, sensitivity experiments suggest that a large part of the total day-2 spread in cyclogenesis cases is associated with the growth of EDA uncertainty, but up to 25 % can be associated with the additional singular vector perturbations to the initial conditions and up to 25 % with the representation of model uncertainty. The sensitivities of spread to resolution, the explicit representation of convection, and the assimilation of local observations are also considered. The study raises the question of whether the EDA now successfully represents initial uncertainty (and the enhanced growth rates associated with cyclogenesis) to the extent that singular vector perturbations could be reduced in magnitude to improve storm track reliability. This would leave a more seamless forecast system, allowing short-range diagnostics to better help improve the model and
model-uncertainty representation, which could be beneficial throughout the
forecast range.
Dialogues in education: Exploring cases from music and mathematics education
Authors: Rinholm Hanne , Solem Ida Heiberg , Ulleberg Inger
Published: July 2023

The aim of this study is to explore how aspects of dialogic teaching are concretized in classrooms to fill the gap between educational rhetoric and classroom practices. A central competency needed in our time is the ability to participate in democratic dialogue. Education for democratic citizenship can be connected to the notion of “becoming human,” which is a central idea in the Bildung dimension of education. The national educational regulations in Norway state that the teacher’s mandate is not limited to conveying knowledge and skills but also includes fostering the students’ critical reflection, inquisitiveness, and participation. The research questions that guided the study are: What theoretical concepts can be helpful in understanding and analyzing dialogic classroom practices? How can participation be promoted through dialogic classroom practice? How do the dimensions of ontological and epistemological dialogue appear in educational settings, and how do they interact with each other? Methodologically, the article presents, analyzes, and discusses two cases from different educational settings: pre-service teacher education music courses and upper-primary-level mathematics education. The findings show that the chosen theoretical concepts of mathematizing, musicking, and Bildung, as well as ontological and epistemological dialogue, are helpful in making sense of dialogic classroom practices.

Published: July 2023

Most of the plant species from the genus Momordica which originated from Asia and Africa have been shown to have functional value, both as food and medicinal plants. However, the quality of utilization of medicinal plants needs to be controlled through accurate authentication, for example through molecular analysis based on DNA barcodes. The matK sequence is one of the most widely used DNA barcode regions in plant molecular studies. Therefore, this study was conducted to determine the genetic variation and phylogenetic relationships of several taxa from the genus Momordica, as well as to analyze the effectiveness of the application of the matK gene as a barcode region in the genus Momordica. The study was conducted by collecting matK sequence data from NCBI in order to obtain sequence data from 12 taxa of the genus Momordica. The data were then aligned and analyzed using MEGA 11 software which included analysis of genetic variation, reconstruction of phylogenetic trees based on Maximum Parsimony, and calculation of genetic distance values using the Kimura-2-Parameter substitution model. The results showed that the molecular analysis of 12 taxa from the genus Momordica based on matK DNA barcode region had been successfully carried out, as evidenced by the successful reconstruction of the phylogenetic tree which showed clear separation both at the interspecies and intraspecies levels. However, the separation that has formed has not been able to show the grouping of taxa based on the origin. Likewise with the calculation of genetic distance values which show consistent results. All analyzes also showed that the matK DNA barcode region has a sequence composition that is quite effective for molecular analysis for genus Momordica, but further studies are required to improve the effectiveness and accuracy of the results provided

Access to global information online is essential for an institution or group. Users who use web-based apps from their homes or other locations may meet their requirements without traveling to the designated institution. This study aims to determine if stakeholders' demands can be met by the web-based application for tuition fee management at the Islamic boarding school "Bilal Bin Rabah" in Sukoharjo. Both documentation and UML (Unified Modeling Language) modeling techniques were employed in this study. The purpose of this application is to make it simpler for administrative staff to handle information on student fee payments and to evaluate financial information for associated parties. Three people may use this application's payment system: the administrator, the head of the Islamic boarding school, and a parent of a student. The administrator may handle student information, and payment information, charge the student’s parents, and print the necessary reports for the Islamic Boarding School. The school's headmaster has access to student data and may generate reports and examine student invoices. The invoices and transaction history of payments that have been made are visible to parents/guardians of students. The website will continue to be developed to support the mobile platform, allowing users to access the school fee management system via mobile more conveniently. Based on the test results, users of the SPP payment system application are quite satisfied.
The Open Arms Day Centre as a Pou Whirinaki and Key Space of Care within the Conduct of Māori Homeless Lifeworlds in Whangārei, Aotearoa, New Zealand
Authors: Finkler Kim , King Pita , Hodgetts Darrin
Published: July 2023

Homelessness has re-emerged as a significant issue in Aotearoa, New Zealand (Aotearoa/NZ) in recent decades, with Māori (Indigenous peoples of New Zealand) being impacted disproportionately due to ongoing processes of colonisation and impoverishment. Whether living on the streets of an urban centre, small city, or rural district, the lifeworlds of homeless people are frequently textured by social, material, and spatial exclusions, uncertainties, insecurities, and stigma. This article explores how the Open Arms Day Centre (OADC), a drop-in day centre for homeless people in Whangārei (a small city in Northland), functions as a dependable Pou Whirinaki (pillar of strength and support) in the everyday lives of Māori experiencing homelessness. Employing a Māori-centred, case-based approach, we explored the experiences of a small group of local service users, volunteers, and staff through interviews, photographic exercises, and regular casual conversations. This culturally informed mode of inquiry resulted in a deeper understanding of the OADC’s operation as what health geographers have also referred to as a space of care. Such spaces offer those frequenting them opportunities for respite, inclusion, belonging, and routine. They become Pou Whirinaki through enactments of Māori relational values and practices that foster a sense of ontological security, cultural continuity, and shared humanity

Published: July 2023

Introducción. En este estudio se aborda el problema de la violencia en las relaciones de pareja adolescente, El objetivo es explorar los factores asociados a su prevalencia y las intervenciones desde el ámbito educativo para erradicar esta violencia. Metodología. Los datos se obtuvieron de entrevistas semiestructuradas a docentes, orientadores/as y educadores/as sociales de Almería y su provincia. Los resultados sugieren que la violencia psicológica es la más manifestada entre las parejas adolescentes, y que la prevalencia de la violencia se debe fundamentalmente a las diferencias de estilos de socialización que ambos progenitores utilizan dependiendo del sexo de sus hijos e hijas, y por supuesto, a los factores culturales vinculadas al origen étnico. Otros factores, pero no menos importante, están relacionados con la influencia de los medios de comunicación, las redes sociales y los iguales. Discusión. Conociendo la visión de profesionales involucrados en el proceso de formación de estos adolescentes, se concluye que, a pesar de que las instituciones educativas están desarrollando varias acciones, la formación y capacitación del personal educativo es un aspecto muy importante a tener en consideración para abordar el tema de la violencia en las relaciones de pareja adolescentes.

INTRODUCCIÓN. El presente artículo tiene como objetivo principal mostrar la tarea del educador como ayuda a la integración personal del educando que tiene por fin la felicidad. Para ello el trabajo se apoya en la distinción entre educación integral e integración personal. Se aborda la noción de sindéresis como aquello que capacita a la persona para hacerse cargo de su propio crecimiento y de orientarlo a la felicidad. MÉTODO. Se trata de un estudio de carácter teórico fundamentado en una revisión bibliográfica de la literatura más relevante y actual de la temática tratada. RESULTADOS Y DISCUSIÓN. Si bien la formación del carácter es un eje fundamental de la educación integral, es insuficiente si consideramos a la persona como un quién. La tarea del educador es doble y cobra su sentido pleno al ayudar al educando a integrar su crecimiento (1) y a orientarlo a la felicidad (2), que no es otra cosa que dando a los demás el perfeccionamiento de la naturaleza adquirido con las virtudes.

Financial inclusion improves the accessibility of the poor and other marginalized groups to basic financial services such as savings, investments, credits, and insurance which directly influences income. This study uses panel data analysis and the two-step Generalized Method of Moments (GMM) estimation to empirically assess the relationship between financial inclusion and unemployment in 49 African countries from 2009 to 2020. The results show that financial inclusion has a negative and significant effect on unemployment. This supports the idea that financial inclusion can help African countries in job creation by reducing unemployment thus it suggests an increase in access and use of financial services. The study also finds that the effect of financial inclusion on unemployment is stronger in countries with higher levels of education. This suggests that education is an important factor in the relationship between financial inclusion and unemployment. The results of the study have important policy implications for African countries that want to reach the Sustainable Development Goals (SDGs). Especially, SDG-8 which promotes inclusive and sustained economic growth with full employment and productivity. Governments should introduce policies regarding the usage of mobile money and microfinance in rural areas to enhance financial inclusion. Moreover, sustaining of economic growth through encouraging foreign direct investment and new business creation may help bring down the unemployment rate.

Authors:   , Clara Sampaio Meira Ana
Published: July 2023

O emprego de alternativas mais sustentáveis para a agricultura, geralmente, acarreta uma produção mais fértil e responsável. A utilização de água residuária e adubação orgânica são práticas que possibilitam esses resultados, desde que seja feito um planejamento e controle das práticas de manejo. Diante do exposto, o presente trabalho, objetivou avaliar o efeito da água residuária de lavanderia pública e diferentes proporções de esterco bovino na produção de mudas de mamão. O experimento foi realizado em propriedade rural, no Distrito de Ribeira, em Cabaceiras-PB, utilizando a frutífera Papaya Formosa como cultivar, e como substrato o Argissolo Vermelho Eutrófico. O delineamento experimental utilizado foi o Delineamento Inteiramente casualizado (DIC), com quatro proporções de esterco bovino (20; 40, 60, 80%), duas águas de irrigação (água de abastecimento (AA), e água residuária (AR)), e três repetições. As variáveis analisadas foram: Número de folhas (NF), Diâmetro caulinar (DC), Altura de planta (AP), Área foliar (AF), Comprimento de raiz (CR), Matéria fresca total (MFT), e Matéria seca total (MST). Com os resultados obtidos, foi possível observar que as maiores doses de esterco bovino, conferem melhores resultados de NF, DC, AP e CR, e que a alta concentração de sódio presente na água residuária afetou negativamente o desenvolvimento da cultura. Porém, as maiores doses de esterco bovino, amenizaram o efeito da salinidade nas variáveis NF, DC e CR.
Mapeamento e análise da erosividade da chuva na sub-bacia do Alto Paraíba.
Authors:   , Kelly da Silva Rayna
Published: July 2023

Dentre os vários fatores que contribuem para a erosão do solo, descritos no modelo EUPS - Equação Universal de Perdas de Solos, destaca-se a Erosividade das Chuvas (fator R), que é um dos mais importantes parâmetros como agente de perda de solo, em razão da sua capacidade de desagregar partículas, pelo impacto das gotas da chuva e gerar escoamento superficial carregando detritos. A EUPS estima as perdas de solo por erosão laminar, através da multiplicação de seis fatores intrínsecos: as características climáticas, propriedades do solo, paisagem do terreno, cobertura vegetal, manejo agrícola e práticas conservacionistas. O foco do estudo foi analisar a erosividade da chuva (EI30) na região da sub-bacia do Alto Paraíba, por meio de geotecnologias, para posterior geração de mapas mensais e anual. O trabalho utilizou dados de precipitação fornecidos pela Agência Executiva de Gestão das Águas (AESA) com 103 anos de observação entre 1911 e 2014. Os dados de erosividade, latitude e longitude foram inseridos em planilha eletrônica com as coordenadas dos postos de cada município. Para a elaboração dos mapas na região de estudo: na distribuição da erosividade, foi utilizado o programa SURFER 11 e; para o mapeamento, foi utilizado o método da Krigagem, onde foram obtidos as médias, medianas, máximas e mínimas, variância e desvio padrão. Quando todos os fatores, com exceção da chuva, são mantidos constantes, a perda de solo por unidade de área de um terreno desprotegido de vegetação é diretamente proporcional ao produto de duas características da chuva: energia cinética multiplicada por sua intensidade máxima em 30 minutos; essa foi a melhor correlação encontrada para expressar o potencial erosivo da chuva. Portanto, informações geradas no trabalho possibilitou a análise da erosividade da chuva na região da sub-bacia do Alto Paraíba, com isso, concluiu-se que o uso de geotecnologias permitiu prognosticar e mapear a erosividade das terras da bacia hidrográfica em estudo com rapidez e agilidade. Foi possível identificar que a distribuição média anual do fator erosividade da chuva foi de 3.477,57 mm.ha-¹.ano-¹. E o desvio padrão do parâmetro erosividade El médio mensal apresentou valor de 639,96 mm.ha-¹, e o coeficiente de variância apresentou valor de 0,184.

The problem in this study is that there are still students who don't have a smartphone, and there are even parents who feel burdened with internet costs or increasing credit which makes it difficult for students to follow the learning process. This can affect students' interest in learning Arabic. so that it can be predicted that online learning has a close relationship in determining student learning interest. This study aims to find out and test empirical data related to the relationship between online learning systems and interest in learning Arabic. In this study the authors used a quantitative method with a correlational approach to quantitative data obtained from the research object, namely class VIII students at MTs Nuril Huda Tarub Grobogan. The sample of this research was 125 respondents from a total population of 182 students. Data collection was carried out using a questionnaire / questionnaire technique. The type of analysis used is a simple correlation analysis which is described descriptively. The results of this study are that there is a positive and significant relationship between online learning and interest in learning Arabic in class VIII MTs Nuril Huda Tarub Grobogan. This is shown by the strength of influence or the correlation coefficient of 0.7234 at the 95% confidence level (α = 0.05), while the magnitude of the influence or coefficient of determination Kp is 0.5184 which means that online learning has an influence on interest in learning Arabic by 52% and means the remaining 48% is determined by other factors. For the significance test, a tcount value of 11.4 is obtained, which means that there is a significant relationship between online learning and interest in learning Arabic

Published: July 2023

Sosyal medya günümüzün en etkili iletişim araçlarından biridir. Yapılan istatistiklere göre Türkiye’de her on kişiden yedisi sosyal medyayı aktif olarak kullanmaktadır. Çeşitli turizm ve rekreasyon alanlarını ziyaret eden insanlar, yaşadıkları deneyimleri sosyal medya üzerinden fotoğraf ve video gibi gönderiler ya da yaptıkları yorumlar ile diğer insanlarla paylaşabilmektedir. Bu paylaşımlar esas alınarak sosyal medya üzerinden elde edilen veriler, turizm alanlarındaki ziyaretçi tercihlerinin anlaşılması noktasında önem taşımaktadır. Bu kapsamda, dört sosyal medya platformu (Instagram, Facebook, Google Haritalar ve Foursquare) üzerinden konum belirtilerek ya da mekân etiketleri kullanılarak, 2012 yılından günümüze dek paylaşılmış olan 406.428 fotoğraf ve 19.538 ziyaretçi yorumu değerlendirilmiştir. Elde edilen veriler ile turizm alanlarının sosyal medyadaki bilinirlik düzeyleri, ziyaretçilerin bu alanlardaki fotoğraf çekim tercihleri ile alanlarla ilgili olumlu/olumsuz yorumları analiz edilmiştir. Elde edilen bulgular, her turizm alanının sahip olduğu doğal ve kültürel değerler bağlamında irdelenmiştir. Son olarak; çalışmanın bulguları ışığında turizm alanlarındaki ziyaretçi memnuniyetinin artırılmasına yönelik öneriler geliştirilmiştir.
Dezvoltarea cooperării europene în domeniul securităţii şi apărării în sprijinul acțiunii externe a Uniunii Europene. Sustenabilitate financiară și convergență instituțională
Authors: ILINCA Dragoș
Published: July 2023

Optimizarea acțiunii externe a Uniunii Europene presupune o abordare cuprinzătoare a modului de utilizare și de racordare a instrumentelor și politicilor relevante ale UE în dezvoltarea interacțiunii și formulelor practice de cooperare cu statele terțe. O componentă extrem de importantă vizează interacțiunea dintre Politica de Securitate și Apărare Comună (PSAC) și acțiunea externă, dinamică, la nivelul căreia, în ultimii ani, s-au consemnat evoluții notabile. Progresele de substanță, înregistrate în dezvoltarea unei formule integrate de promovare a acțiunii externe, validează ipoteza centrală a studiului de față, potrivit căreia cooperarea europeană în domeniul apărării tinde să devină unul dintre elementele de susținere importante a acțiunii externe. Pornind de la această premisă, o altă direcție de analiză aprofundată în paginile următoare vizează relația ambivalentă dintre susținerea financiară, pe care acțiunea externă o receptează prin intermediul noului Cadru multianual 2021-2027, și inițiativele concrete, dezvoltate sub egida PSAC, cu aplicabilitate în domeniul militar.

Plantations are efficient sequesters of carbon and can mitigate the predicted rise in atmospheric CO2 concentration and future climate change. Trees can capture atmospheric CO2 through photosynthesis and store it in biomass with a turnover time of several decades. The present investigation was undertaken to study the carbon stock in biomass of important plantation species of clonal and seedling origin in the Southern agro-climatic zone of Tamil Nadu. The existing stands of three different ages of a tree plantation were selected from within the available plantations on farmlands, and data on girth and height were recorded for all the trees. The results revealed that the total carbon stocks (537.8 Mg ha-1) was maximum under Eucalyptus clonal plantation of >6 years. Aboveground biomass was greater than belowground biomass, accounting for 79% of total biomass in Casuarina clonal plantation of > 5 years. Biomass carbon stock in Melia increased from 49.8 Mg C ha-1 in 1 to 4 years plantation to 95.5 Mg C ha-1 in >7 years old plantation. The findings explain the ability of clonal plantations of Casuarina and Eucalyptus in accumulating maximum biomass carbon stock.

An experiment was conducted at main Horticulture Research Farm, Lovely Professional University Phagwara, Punjab during the period from February-May 2021 and 2022. To overcome the problem of seed germination in okra, it can treated with water which are farmers friendly and cost effective. The objective of the experiment was to determine how long okra seeds should be hydroprimed in order to influence germination percentage and seedling performance in okra. There were eight treatments in which one is unprimed and other seven are primed with distilled water for different durations [T1 , 2 hours hydroprimed seeds; T2 , seeds hydroprimed for 4 hours; T3 , seeds hydroprimed for 6 hours; T4 , seeds hydroprimed for 8 hours; T5 , seeds primed for 10 hours; T6 , seeds primed for 12 hours; T7 , seeds primed for 14 hours]. The experiment was laid downin a Randomized Complete Block Design (RCBD) with three replications. Data of various parameter likes germination percentage (%) and seedling parameters were recorded to find out the suitable duration of seed hydropriming in okra. Result of the study showed that hydropriming duration of 12 hours recorded maximum seed germination percentage (83.33%), minimum days for germination (7.17), length of shoot (16.56 cm), length of root (8.64 cm), seedling length (25.20 cm), seedling dry weight (25.26 mg), seed vigour index-I (1823.89) and seed vigour index-II (2105.35) as compared to other hydro priming durations. It was concluded that 12 hours of hydropriming duration had positive effect on germination and seedling growth parameters of okra.
