The Study of Water Content on the Coal Loading Performance of Thin Coal Seam Shearer Drum by Discrete Element Method (DEM)

ABSTRACTAs the main component of thin coal seam shearers, the drum bears the functions of loading and cutting, and its performance has become an important factor restricting mining efficiency and production safety. In response to the problem of low efficiency in installing thin coal seam shearers, this paper uses the Discrete Element Method (DEM) to study the effects of loading methods, helical angle of drum, drum rotation speed, and particle water content on coal loading rate. Research has found that the coal loading performance of the ejection loading method is much higher than that of the pushing loading method. As the helical angle increases, the average loading rate increases. As the rotation speed increases, the loading rate of wet coal particles gradually decreases. During production and thin coal seam mining, special attentions should be paid to the control of helical angle of drum and drum rotation speed. This study has guiding importance for improving the efficiency of thin coal seam mining.

Limited Practical Effect of APEC ODR: A Comparative Analysis of Platform ODR and APEC ODR

Abstract: The actual demand and effect of the ODR (Online Dispute Resolution) mechanism in the field of cross-border e-commerce dispute resolution are relatively limited, and the protection of the ODR mechanism within small and medium-sized cross-border e-commerce platforms is insufficient. The reasons why the ODR mechanism cannot be fully applied to such platform disputes include the complexity of cross-border, diverse types of disputes, cost of time and money, and limited scope of application of the ODR mechanism. In addition, the lack of neutrality and standardized operating rules of the ODR mechanism within the e-commerce platform directly affects the fairness of dispute resolution. Although APEC (Asia-Pacific Economic Cooperation) ODR mechanism has shown significant advantages in improving efficiency and ensuring information security, it fails to effectively balance efficiency and fairness in terms of application scope and practical effect. Based on this, there are insufficient fairness problems in the automatic process mechanism, evidence collection procedure, and process deadline setting in the APEC ODR process. In the future, the APEC ODR and other international dispute resolution mechanisms will continue to be more internationalized and standardized. In addition, we have to be alert to the anti-globalization risks reflected in the APEC ODR, avoid geopolitical interferences as much as possible, and prevent the emergence of trade protectionism.

Global Trade Tensions: Analyzing the WTO Legality of the U.S. Inflation Reduction Act and Strategic Responses

With the profound changes in the global economic landscape and the increasing proximity of the United States and China in terms of power contrasts, the hegemonic anxiety of the U.S. has been increasing, leading to the adoption of a series of protection measures in the field of trade. Among them, the Inflation Reduction Act, as an important part of the U.S. trade protectionist policy, its implementation has not only aggravated the tension in international trade, but also violated the relevant rules of the World Trade Organization (WTO). This paper elaborates the specific content of the Act and its impact on international trade, especially its large-scale subsidy policy in the field of green energy and its potential impact on the global supply chain. Subsequently, this paper analyzes in depth the illegality of the Act under the WTO framework from the perspective of prohibited subsidies and non-discriminatory principles, and argues with specific cases. Finally, this paper puts forward China's response strategy, aiming to provide theoretical support and practical guidance for China in dealing with U.S. trade protectionist policies. The purpose of this paper is to reveal the nature and impact of the U.S. trade protectionism policy, to provide theoretical support for China to safeguard its legitimate rights and interests in global trade, and to provide useful reflections and insights for China to promote trade liberalization and facilitation, strengthen international cooperation, and jointly respond to challenges in the context of global economic integration.

The Influence of Sino-US Trade Friction on the Export Volume of China's High-tech Products

With the rapid development of economy, witnessing the extraordinary progression of the economy, China has ascended as the second largest economy globally, and the gap with developed countries is getting smaller and smaller. For a long time, there has been a huge trade deficit from China to the United States. The United States provoked trade friction on the grounds of trade protectionism, restricting trade with China, high-tech industries being the focus. Employing the difference-in-differences (DID) methodology, this paper scrutinizes the influence of Sino-US trade frictions on the export value of China's high-tech industries, utilizing the export data of China's high-tech industries to the United States spanning from 2012 to 2022. It is found that after the Sino-US trade friction began, China's exports of high-tech products to the United States have declined significantly, which has caused trade destruction effect and trade deflection effect from China to the United States.

Refrigerated amniotic membrane maintains its therapeutic qualities for 48 hours

During wound healing, the migration of keratinocytes is critical for wound closure. The application of amniotic membrane (AM) on wounds with challenging contexts (e.g., chronification and diabetic foot ulcer) has proven very successful. However, the use of AM for clinical practice has several restraints when applied to patients; the most important restriction is preserving AM’s therapeutic properties between its thawing and application onto the patient’s wound. Moreover, AM collection and processing requires a cleanroom, together with specialized staff and equipment, and facilities that are not usually available in many hospitals and healthcare units. In this publication, we kept previously cryopreserved AM at different temperatures (37°C, 20°C, and 4°C) in different media (DMEM high glucose and saline solution with or without human albumin) and for long incubation time periods after thawing (24 h and 48 h). HaCaT keratinocytes and TGF-β1-chronified HaCaT keratinocytes were used to measure several parameters related to wound healing: migration, cell cycle arrest rescue, and the expression of key genes and migration-related proteins. Our findings indicate that AM kept in physiological saline solution at 4°C for 24 h or 48 h performed excellently in promoting HaCaT cell migration compared to AM that had been immediately thawed (0 h). Indeed, key proteins, extracellular signal-regulated kinase (ERK) and c-Jun, were induced by AM at 4°C in saline solution. Similarly, cell proliferation and different genes related to survival, inflammation, and senescence had, in all cases, the same response as to standard AM. These data suggest that the handling method in saline solution at 4°C does not interfere with AM’s therapeutic properties.

The Unsettled Governance of the Dual-Use Items under Article XXI(b)(ii) GATT: A New Battleground for WTO Security Exceptions

Abstract In an era marked by the ‘technologization’ of modern warfare and the privatization of military supply chains, numerous items possess dual-use potential, capable of serving both civilian and military ends. Concurrently, governments increasingly view the acquisition of specific goods, materials, services, and technologies by rival states as a threat to their security. As a result, economic restrictions imposed on dual-use items, including export controls, have proliferated in recent years. These measures have elicited concerns regarding disguised protectionism and potential non-compliance with trade agreements. Central to the debate is the difficulty to strike a balance between addressing legitimate security imperatives and preventing economic protectionism. This article delves into the intersection of trade and security in the regulation of dual-use goods. It offers a focused examination of Article XXI(b)(ii) of the General Agreement on Tariffs and Trade (GATT) concerning trade restrictions on products destined for military use. The paper first reveals limitations of this provision in governing the regulation of dual-use items. Furthermore, it introduces the concept of a ‘purpose test’ provided by the provision as a safeguard against abusive invocation. Lastly, it sheds light on the challenge posed by the standard of proof issue, which complicates the review and mitigation of bad-faith invocations of security exceptions.

Juvenile hormone as a key regulator for asymmetric caste differentiation in ants

Caste differentiation involves many functional traits that diverge during larval growth and metamorphosis to produce adults irreversibly adapted to reproductive division of labor. Investigating developmental differentiation is important for general biological understanding and has increasingly been explored for social phenotypes that diverge in parallel from similar genotypes. Here, we use Monomorium pharaonis ants to investigate the extent to which canalized worker development can be shifted toward gyne (virgin-queen) phenotypes by juvenile hormone (JH) treatment. We show that excess JH can activate gyne-biased development in workers so that wing-buds, ocelli, antennal and genital imaginal discs, flight muscles, and gyne-like fat bodies and brains emerge after pupation. However, ovary development remained unresponsive to JH treatment, indicating that JH-sensitive germline sequestration happens well before somatic differentiation. Our findings reveal important qualitative restrictions in the extent to which JH treatment can redirect larval development and that these constraints are independent of body size. Our findings corroborate that JH is a key hormone for inducing caste differentiation but show that this process can be asymmetric for higher colony-level germline versus somatic caste differentiation in superorganisms as defined a century ago by Wheeler. We quantified gene expression changes in response to JH treatment throughout development and identified a set of JH-sensitive genes responsible for the emergence of gyne-like somatic traits. Our study suggests that the gonadotropic role of JH in ovary maturation has shifted from the individual level in solitary insects to the colony level in an evolutionary-derived and highly polygynous superorganism like the pharaoh ant.

She Doesn’t Even Know She Made Them: Ambiguous Attribution in Italian Exploitation Films

Abstract Starting in the late 1950s, exploitation filmmakers operating in Italy sometimes used pseudonyms, allonyms or prestanomi. This article examines the multiplicity of motivations behind this practice, and attempts to untangle some of the implications of the use of pseudonyms in Italian exploitation cinema, especially as it relates to the complex dynamics of gender and nationality in the film production sector. It compares the case of the alias O. Hellman, which appears in a small number of exploitation films in the 1970s, with similar ones from that period, including ones in which the ambiguity of authorial attribution involves husband and wife teams – an ambiguity fascinatingly compounded by the protectionist measures of Italian film policy and the contradictory evidence of primary and secondary sources. Finally, the article reflects on the implications of this practice on data-based gender research in the Italian film industry.

Synthesis of Ultrathin Film PEGDMA Hydrogels Coated onto Different Surfaces by Atmospheric Pressure Plasma: Characterization and Potential Features for the Biomedical Field

AbstractThe preparation of resistant ultrathin film (utf) hydrogels coated onto different working surfaces (e.g., fabrics) is paying increasing attention as an advantageous strategy for customizing their resultant properties. More specifically, poly(ethylene glycol) (PEG)‐based utf‐hydrogels are relevant for their superior biocompatibility or antibiofouling properties. However, promoting the generation of poly(ethylene glycol) dimethacrylate (PEGDMA) cross‐links ideally without the use of initiators or other cross‐link agents, which might compromise the final bioactivity of the system, is complicated. Moreover, the actual synthesis techniques used for the preparation of such utf‐hydrogels face important drawbacks like high scale‐up costs or important geometrical restrictions, completely hindering its technological transfer. Herein, for the first time and easy and technologically scalable technology is reported for the synthesis and direct deposition of PEGDMA400 utf‐hydrogels onto different substrates based on atmospheric pressure nanosecond pulsed plasma approach. The advantages of the technology are explored and discussed, reporting the ready‐to‐use transparent coating of fabrics. After washing the samples using washing programs of a commercial laundry machine, coatings are still well adhered, showing excellent stability. Finally, the resultant properties of PEGDMA400 utf‐hydrogels are exhaustively characterized using in operando conditions in order to elucidate their potential capabilities in the biomedical field.

Researching into Preventing Harmful Rent-Seeking Practices: Strategic Policy Interventions Required and Lessons Learnt for Asian Countries

The author of this work argues that rent-seeking occurs in a situation wherein a company or individual seeks special privileges from another party, often the government, but does not reciprocate back. Its examples are (a) license requirements for professions; (b) creating barriers to entry for new businesses, and (c) grants, subsidies, or tariff protection. In the language of economics, rent is defined as “wealth gained via questionable, often manipulative means”.A closer look at the theoretical perspective and review of related literature is indicative of the fact that identification (and practice) of policy-induced harmful rents have been resorted to in many firms and for various purposes. More specifically, the practice of rent-seeking model has been found to be resulting in both economic ‘gains’, and ‘losses’. The bottom-line is that there is a lack of scientific research evidence and published data on how national governments and donor agencies (from across the regions of the globe) have formulated and adopted rent-seeking approaches. The author of this research essay argues that in view of these contradictions and controversies, it is important for the academic and research community to seek answers to pertinent questions on potential advantages of rent-seeking approach. The questions that need to be debated and researched into are:a) what are the approaches to identify policy-induced harmful rent-seeking practices? b) what are their respective strengths and weaknesses? c) how governments and donors have used them in different perspectives? The author, in this paper, aims to seek answer to the above prominent and key questions in the context of countries in the Asian region. In terms of research methodology, secondary data (that are largely ‘quantitative’ in nature) have been used and method of data analysis is descriptive (involving “desk-based research” approach). Data sources have been quoted in the text (including under references). The paper briefly concludes that the rent-seeking activity might be negative, but it might preserve a “growth-enhancing rent”. Even if the rent-seeking activity has a positive value, the “outcome-rent” might be negative. Governments, thus, need to be more transparent in adopting rent-seeking practices; people know how laws and regulations are produced. This renewed critical and multidisciplinary approach has important policy implications for the debates over institutional reform in rent-seeking practices for economies in Asia and the Pacific.In conclusion, the author says that the analysis of rents and rent-seeking practices has been primarily dominated by an economic point of view. This perspective places emphasis on assessing rents in accordance with their impact on “efficiency and economic growth”. As against political approach to rent-seeking (which assumes the negative impact of rents and their potential to derive from corrupt activities), monetary policy experts and economists classify rents as “growth-retarding” (or “growth-enhancing”).In terms of implications of harmful rent-seeking practices for monetary policy, the author of this work argues that the rent-seeking framework has to be extended by incorporating policy insights and strategies developed by stakeholders in the governmental sector and institutional economists if it is to explain the anomalous role played by rent-seeking in Asian countries. This mechanism includes detailed analysis of economy in the broader context in countries such as Thailand, Malaysia, the Philippines, and Indonesia (including the Indian sub-continent).

Marker-Assisted Selection of Jacalin-Related Lectin Genes OsJRL45 and OsJRL40 Derived from Sea Rice 86 Enhances Salt Tolerance in Rice.

Soil salinization limits rice growth and is an important restriction on grain yield. Jacalin-related lectins are involved in multiple stress responses, but their role in salt stress responses and use as molecular markers for salt tolerance remain poorly understood. Salt stress treatments and RT-qPCR analyses of Sea Rice 86 (SR86), 9311, and Nipponbare (Nip) showed that OsJRL45 and OsJRL40 enhanced tolerance of salt stress in SR86. Molecular markers based on sequence differences in SR86 and the salt-sensitive variety, 9311, in the intergenic region between OsJRL45 and OsJRL40 were validated in recombinant inbred lines derived from SR86 and 9311, hybrid populations, and common rice varieties. Yeast two-hybrid and bimolecular fluorescence complementation demonstrated that OsJRL45 and OsJRL40 interacted. Co-transformation of Nip with OsJRL45 and OsJRL40 derived from SR86 had no effect on the mature phenotype in T2 plants; however, salt stress at the three-leaf stage led to significant increases in CAT, POD, SOD, and Pro contents, but reduced MDA content in transgenic plants. Transcriptomic analysis identified 834 differentially expressed genes in transgenic plants under salt stress. GO and KEGG enrichment analyses indicated that metabolic pathways related to antioxidant responses and osmotic balance were crucial for salt-stress tolerance. Thus, molecular markers based on nucleotide differences in OsJRL45 and OsJRL40 provide a novel method for identifying salt-tolerant rice varieties.

Constructing Disraeli in Twentieth-Century Conservatism

Abstract Since the 1960s, when historians first dethroned the dominant view of Benjamin Disraeli as a Tory democrat and social reformer, his association with an interventionist, socially inclusive Conservatism has largely been considered an exercise in political myth-making. This focus on the Disraeli ‘myth’ has tended to obscure the myriad and substantive ways in which Disraeli’s life and works were interpreted and put to work in Conservative ideological debates and political practice in the twentieth century, reducing them to social policy and state intervention in the economy and overlooking the lineages of his political career in Conservative political economy debates, conceptions of the nation and the constitution, and imperial and foreign policy thinking. This article examines interpretations of Disraeli, and how his legacy was constructed, by conservative biographers, historians and public intellectuals from the decades after his death until the historiography of the 1960s. It traces how Disraeli was memorialised and celebrated in the Conservative movement and popular culture; how his life and works were interpreted for popular audiences by an important group of conservative historians in the inter-war period; and how Disraeli was mobilised in Conservative and Unionist Party debates on tariff reform, social reform, the nation and empire, concluding in the aftermath of the Second World War, when his legacy and statecraft were consistently evoked in Conservative debates on post-war Britain. It demonstrates that Disraeli was interpreted in much more diverse ways, and with more diverse political objectives, than the standard readings of the Disraelian tradition have hitherto appreciated.

Polish Conductresses and the Insecurities of Female Labour Migration to France, 1925–1929

In this article we argue that the reports of conductresses accompanying female migrants shed new light on the nature of interwar labour migration. As they mitigated the anxiety and insecurity that women faced during the process of migration, they fulfilled a crucial role in the highly restrictive post-1918 international migration regime. The Polish government introduced conductresses in 1925 to respond to news of the mistreatment and sexual exploitation of Polish women working in France. Developed in close collaboration with international organizations and the League of Nations, the work of these conductresses on land and sea routes was framed as those of ‘moral guardians’ protecting female migrants from the dangers of sex trafficking. However, we argue that their main function was to mitigate the uncertainties of the post-war international order, as traditional routes of migration were ruptured and both dispatching and receiving countries attempted to control and restrict migration. Female migrants had no networks with existing diasporas, were often illiterate, and mistrusted both Polish and French institutions. By addressing these challenges, the conductresses took on roles far beyond their function as moral authority: they acted as translators, knowledge imparters, mediators, and network forgers. Both in Poland and at the international level, the Polish conductress scheme was regarded a success, as they managed to provide a relatively ‘secure’ migration experience within a migration regime designed to walk a fine line between demands for foreign labour on the one hand and the rising ideal of economic protectionism on the other.

The omitted variable: musical bamboos, environmental sustainability, and the ecological implications of an intangible cultural heritage in the Bolivian Andes

ABSTRACT This article examines the heritagization process of the highland flute-making community of Walata Grande, focusing on the environmental sustainability of native woody bamboos used in flute making in the Bolivian Andes. It explores how Aymara flute makers’ involvement in national cultural heritage politics intersects with broader ecological issues of resource use and environmental sustainability from an ecomusicological perspective. Through ethnographic fieldwork among flute makers, bamboo traders, and cultural heritage state officials, I analyse how Walateño flute makers view their cultural heritage as a means of decolonisation, economic protectionism, and tourist promotion. Simultaneously, they avoid discussions about musical bamboos due to concerns over losing autonomy in the management of an essential resource. I conclude that the intangible cultural heritage initiative in highland flute making offers only a limited solution to the challenges of sustaining musical bamboos. Although UNESCO’s Convention for the Safeguarding of the Intangible Cultural Heritage (ICH) advocates for the constant recreation of ICH by heritage communities, it is crucial to consider the material economic structures in which these cultural recreations are embedded and their ecological and environmental implications, especially given the current context of musical bamboo unsustainability.

Research on China-Sri Lanka Economic and Trade Cooperation Based on SWOT Analysis

This paper systematically explores the economic and trade cooperation between China and Sri Lanka based on the SWOT analysis framework. Against the backdrop of globalization and the “Belt and Road” initiative, China-Sri Lanka economic and trade cooperation shows great potential and broad prospects. By using the SWOT analysis method, the paper comprehensively analyzes the strengths, weaknesses, opportunities, and threats of China-Sri Lanka economic and trade cooperation. The strengths include complementary geographical locations, complementary trade structures, and a solid foundation of political mutual trust; the weaknesses mainly lie in trade imbalances, unstable investment environments, and cultural and communication barriers; opportunities mainly arise from the promotion of the “Belt and Road” initiative, the deepening of regional cooperation, and changes in the global trade pattern; threats mainly come from changes in the international political and economic environment, external shocks such as pandemics, and the rise of trade protectionism. Finally, the paper proposes targeted strategic suggestions based on the actual situation, aiming to promote the sustainable and healthy development of China-Sri Lanka economic and trade cooperation and enhance the economic prosperity and well-being of the two countries.

Systems thinking in sustainable agriculture development: a case study of garlic production in Indonesia

Sustainable agriculture involves complex interactions among social, economic, and ecological dimensions, each with distinct interests and goals. Achieving sustainable agricultural development is challenging and requires a comprehensive response. This study focuses on Indonesia’s garlic production, employing a systems thinking approach to provide a holistic understanding of the interconnected factors influencing sustainable agricultural systems. We utilized the first two steps of the five-step systems thinking methodology—problem articulation and the formulation of dynamic hypotheses. This process involved developing a causal loop diagram (CLD) to represent the dynamic hypotheses and identifying system archetypes to determine leverage and potential intervention points. Our analysis identified three system archetypes—Drifting Goals, Fixes that Fail, and Limit to Growth—as key patterns influencing the sustainability of garlic production. The Drifting Goals archetype reveals that efforts to boost local garlic stock in Indonesia are hindered by the allocation of garlic for seeds, due to the lack of a clear distinction between garlic for consumption and seed. The Fixes that Fail archetype illustrates the long-term detrimental effects of short-term agricultural practices, such as the overuse of chemical fertilizers and pesticides. The Limit to Growth archetype underscores the critical need for enhanced market access and a shift in consumer preferences to sustain garlic farming. To address these challenges, we recommend establishing clear distinctions between garlic for consumption and seed production, developing the seed industry, promoting integrated pest management, and reducing reliance on chemical inputs through environmentally friendly technology. Additionally, ensuring market and price stability is vital to maintain farmers’ interest in garlic cultivation. Therefore, the government should prioritize market penetration for local garlic and consistently enforce import restrictions to ensure the sustainability of garlic production in Indonesia.

The Influencing Factors of RMB Exchange Rate in the Background of Anti-globalizationAn Empirical Evidence Based on VAR Model

Affected by the epidemic and geopolitics, global economic growth has slowed down, trade protectionism has begun to emerge, and anti-globalization sentiment has begun to sprout. With the pace of the Federal Reserve's interest rate hike, the global exchange rate, especially the RMB exchange rate, is gradually under pressure, which has a great impact on the economy and financial sector of the whole country. The research topic of this paper is the influencing factors of the RMB exchange rate in the background of anti-globalization, and the empirical analysis of the VAR model based on Stata software. The study found that rising domestic interest rates, a rising balance between import and export trade and rising uncertainty about US economic policy will lead to the appreciation of the RMB, while the growth of money supply will lead to the depreciation of RMB. It is worth noting that the RMB exchange rate is less affected by the uncertain economic policy factors in the United States, which shows that under the current anti-globalization and international game background, China still has a relatively independent control of the foreign exchange market.

Do Protective Tariffs Influence Firms’ Competitive Stance? Application of a Competitive Leverage Model in The Presence of Simultaneous Equation and Sample Selectivity Bias

ABSTRACT: We propose a Competitive Leverage model, and apply it to analyze the impact of tariffs on the attitudes of domestic import-competing firms, especially regarding their disincentives to maintain a Competitive Stance against foreign competitors in the domestic market. We propose that tariffs are a disincentive to the pursuit and maintenance of production efficiency in firms and industries. When countries implement tariff protection for their domestic firms, the most common excuse sounds reasonable, except that it is also economically flawed. While the short-run impacts of such a measure might seem plausible, its long-term effects appear to be less than favorable, and may, in fact, turn out to be damaging to the economy. The paper applies the competitive leverage concept in a unique way to highlight how tariffs distort the output levels of domestic firms, and gives an empirical analysis of the model, using USA data to verify the predictions of the model. Particularly, we develop a Cournot-competition type Competitive Leverage model, and use it to examine the role played by tariffs as a disincentive to a typical firm’s pursuit and maintenance of production efficiency. The competitive leverage model is formulated and applied to verify the effects of tariff protection from the typical domestic firm’s strategic interaction standpoint. We further apply cross-sectional data to carry out an empirical analysis of the model, to verify how tariffs impact the domestic firm’s output and pricing decisions. Our findings would enable us to contribute to the debate about the need to remove protective tariffs, on the grounds that tariffs do not only enable domestic firms to operate inefficiently, but also tends to distort the output and pricing outcomes that would otherwise have been realized in the free market. The results from the study are used to propose some major policy implications of imposing tariff protection, among which are that there is need for implementation of more deliberately sustained Research and development program on the part of domestic firms in the economy, to enable them withstand vigorous competition in a free-trade world. Also, since protective tariffs significantly increase firms’ profit rates, which in turn enables them to unduly earn and accumulate economic rents that amount to inefficiencies and distortions in free-market prices and quantities outcomes, governments should always resist any pressures from big businesses to impose protective tariffs against competition from international rivals. Yet a clear public policy implication from this paper is that, at the macro level, as the results suggest that a government policy that aims at protecting domestic firms through imposition of tariffs may have an adverse effect on the firms’ competitive stance in the industry, a practical message is for the government to impose only a moderate tariff at the most, if it must, especially as it relates to agricultural products.

Non-composted and blended agro-industrial by-products an as alternative soilless substrate affect potted zonal geranium (Pelargonium x hortorum) and murva (Murraya paniculata) production

Due to their hiking prices and import restrictions, peat moss and coco coir are not readily available in many developing countries including Pakistan. Therefore, it is necessary to explore alternative soilless substrates having low cost and comparable physico-chemical properties with peat moss and coco coir for local and global market. For this purpose, indigenous agro-industrial by-products, viz., sesame straw, date palm coir, sugarcane pressmud, sugar beet waste and pine bark were collected, cleaned, crushed (where needed) and blended for physico-chemical analyses. Zonal geranium ‘Pinto White’ and murva (Murraya paniculata Kaneh.) were used to evaluate the efficacy of various combinations of substrates on plant growth and production. Three experiments were conducted with six treatments of each experiment replicated three times. Blending of sesame straw with sugarcane pressmud and pine bark (4:4:2 by volume) yielded best results and marketable plants were produced with tallest height (35.8 cm), canopy diameter (20.8 cm), leaf area (29.2 cm2), leaf total chlorophyll contents (62.1 SPAD) and flowers per plant (5.0 No.) along with shortest production time (103 days). Same results were recorded when murva plants were grown in 4:4:2 blending of sesame straw, sugarcane pressmud and pine bark. Zonal geranium and murva plants did not perform well when sesame straw was blended with date palm coir and sugar beet waste. Blending of sesame straw with sugarcane pressmud and pine bark had low pH (7.0), electrical conductivity (1.37 mS cm-1), bulk density (0.29 g cm-3) while high water retention (34.7 %) as compared to other blended substrates. However, shrinkage of substrates in containers was highest (7.7 %) when sesame straw was blended with sugarcane pressmud and pine bark in 5:3:2 followed by 4:4:2. pH value of all blended substrates decreased at termination except when sesame straw, sugarcane pressmud and pine bark were blended in 4:4:2 and 5:2:3, which was increased from 7.0 to 7.1. Electrical conductivity of all blended substrates was decreased at termination of the experiments. It can be concluded that blending of sesame straw, sugarcane pressmud and pine bark in 4:4:2 (v/v/v) significantly improved physico-chemical characteristics of substrates as well as plant growth and production attributes of zonal geranium and murva. Therefore, this indigenous soilless substrate, which is cheaper and readily available to nurserymen can be used as alternative of peat moss and coco coir for containerized plant production.
