During the COVID-19, the recovery of the world economy is facing a severe challenge. Specifically, a revolution in science and technology is developing in depth and due to the change of global economic industrial transformations are taking place gradually. For the sake of analyzing the effects of innovation and entrepreneurship on the upgrading of industrial structure (UIS), this study uses the data of the number of scientific and technological achievements, fiscal expenditure and industrial structure in China from 1995 to 2019 were selected as the research variables. Besides, the correlation between variables was analyzed based on vector autoregressive model (VAR), Johanse cointegration test, VECM, and also impulse response analysis. Empirical analysis indicates that a long-term equilibrium relationship exists between innovation and entrepreneurship, fiscal expenditure and the upgrading process. Innovation and entrepreneurship and fiscal expenditure have a positive effect in promoting the structure. These discussions shed light on guiding further exploration of guiding the main path break-throughs and policy management in the new era.

Analyzing the data from beverage companies to evaluate the validity of the Fama-French three-factor model
Authors: Xue Wenhui
Published: December 2022

The Fama-Fench 3-factor model (FF3) is one of the most commonly used models for valuing companies. It is curious to see whether this model can reasonably capture the changes in the treacherous stock market and accurately predict the expected returns of a company in practice. In this article, machine learning is adopted to analyze data from the past five years in terms of the 10-year t-bill return as the risk free rate and the S&P 500 rate of return as the market rate of return to compare and analyses the rate of return of Nestle, Danone, Unilever, Coca-Cola and PepsiCo over the past five years. In the comparative analysis, this essay randomly selected the rate of return for 80% of the days in the past five years as the training set and used the rate of return for the remaining 20% of the days as the test set. Besides, this study uses regression analysis to obtain a theoretical model of FF3, which is then brought to the test set data for testing. In this article, the null hypothesis is that the error is equal to 0 and the alternative hypothesis is that the error is not equal to 0. According to the analysis, hypothesis validation is adopted to check the accuracy of FF3 by analyzing the results of the hypothesis test and using the FF3 derived from the training set to predict whether the error between the resulting data and the actual data is 0.

Published: December 2022

Magnesium alloys emerge as a new class of biomaterials in medical field especially in orthopedic applications as medical implant because of its excellent mechanical, biocompatible, bioactive and biodegradable properties. Biodegradable magnesium alloys attracted great attention of researchers to avoid implant removal surgery after healing process. The magnesium alloy samples were anodized in two different electrolyte solutions to further improve the biodegradability of the substrates. The processing time varies from 10 minutes to 40 minutes with constant voltage of 20V. coated samples were characterized with scanning electron microscopy (SEM) for surface topography and energy dispersive x-ray spectroscopy (EDX) confirmed the deposition of thick and dense oxide layers of anodized film of magnesium oxide (MgO) and magnesium hydroxide Mg(OH)2 in electrolyte 2. The results of electrochemical Impedance spectroscopy (EIS) are in a good agreement with the analyses of surface morphology. The anodic film formed by electrolyte 2 provides better biodegradability as compared to electrolyte 1.
Beyond efficiency in low-income housing provision: Everyday negotiations of nonprofit staff and the limits to caring through marketized housing in Buffalo, New York
Authors: Prater-Lee Gillian
Published: December 2022

This paper analyzes how conflicting understandings of housing – housing as a commodity, a financial asset, a human right, and/or a form of service provision – coalesce in and are negotiated by nonprofit organizations that oversee low-income housing in Buffalo, New York. Critically analyzing nonprofit organizations as sites where discourses about housing come into conflict, I argue that the work of nonprofit staff materializes into the conditions of the contemporary system of housing provision and these organizations are important sites of everyday resistance to the marketization of low-income housing in the US. Through an institutional ethnography, I track how nonprofit workers fill the gaps in the private housing market in meeting the housing needs of low-income households. I also show how the marketization of low-income housing constrains nonprofit workers’ ability to enact a politics of housing as a right or a form of care. I look to the literature of feminist care ethics to argue that a broader, communal, and embodied understanding of housing provision could provide an alternative, non-marketized basis for a more just housing system – but one that must necessarily exceed the contemporary housing system.
Intimate Others: Utopia and Heterotopia in the Reluctant Fundamentalist and the Submission
Authors: Khalifa Mahmoud
Published: December 2022

The Submission and The Reluctant Fundamentalist invest in the strategic ambivalence that characterizes heterotopias. Steering away from trauma studies I concentrated on the possibilities the concept of heterotopia offers to understanding the multilayered content and symbolism of the two post 9/11 novels. Heterotopia as a Foucauldian concept established spaces that are ‘other’ in relation to a normal space. I extend that other space to include Muslims as belonging to a heterotopic garden from which they challenge an Islamophobic and divisive discourse that is affiliated to power and uses the popular media and grievances of the 9\11 families to further cut off Muslims from contribution to mainstream society.

Published: December 2022

Particularly for newspapers, the modern era is turbulent and full of changes as more news sources migrate to online services. Print media is gradually becoming a dinosaur's method of information gathering, but are news stories in internet media more trustworthy and believable than those in printed media? The conformists and the revolutionaries have engaged in an ages-old dispute over this issue. Many trustworthy news sources have switched from print to online publishing and subscriptions since the turn of the last decade. People are relying more and more on their screens rather than paper to consume information. Their phones were constantly buzzing and beeping, alerting them that there had been another large-scale shooting in the United States. The present study is based on the credibility and trustworthiness of both print media and social media in a not-so-big city like Bhubaneswar.
The Impact of Self-Assessment with Goal Setting on Academic Achievement: Results of a Study on Primary School Students in Greece
Authors: Papanthymou Anastasia , Darra Maria
Published: December 2022

The main purpose of the present study is to investigate the contribution of Self-Assessment with Goal Setting (SAGS), which was implemented with the “self-directed learning” (SDL) method, to the improvement of academic performance in the context of language teaching to sixth-grade students in primary school. The research methodology followed is an experimental design with two groups, one experimental and one control. The research was implemented in public primary schools in Rhodes and lasted for six weeks (from the beginning of March 2022 to the middle of April 2022). The research sample is a convenience sample consisting of 163 students (the control group made up of 78 students and the experimental group consisting of 85 students). According to the findings of the study, the students in the experimental group improved their performance, and this improvement was statistically significant. Specifically, it was observed that after the implementation of SAGS, the mean score for academic achievement of the students in the experimental group was higher than the mean score of academic achievement during the pretest period. Furthermore, the vast majority of students in the experimental group improved their academic achievements, while a very small number of students experienced a decrease in performance and an even smaller number of students did not experience any change in their performance after the intervention. Finally, the students in the experimental group also performed better posttest and improved their performance, in contrast to the students in the control group for whom both lower performance and a deterioration in their performance were observed compared to the experimental group.
Kindergarten Administration and Faculty Agreement on Measuring Educational Effectiveness and Proficiency
Authors: Shanbhogue Girish
Published: December 2022

This study was to compare kindergarten teachers' and administrators' assessments of teachers' competence and performance in the classroom. A survey was developed as part of a quantitative methodology for the investigation. Purposeful sampling was used, which is a kind of non-probability sampling. There was a total of 280 participants, including 170 kindergarten teachers and 110 principals from around the nation. “Cohen's Kappa coefficient” was used to establish the degree of agreement between raters, and the Pearson Chi-Square test was used to find any discrepancies between the views of principals and teachers that emerged from the data acquired through questionnaire. The results revealed that the raters were not generally in agreement with one another, indicating that there are likely different perspectives held by teachers and administrators. Multi-rater strategies are seldom used in this kind of study, and this is particularly true for the ECE level in the country. Studies of educators' abilities and efficacy often include a single rater, such as classroom instructors or school administrators rating themselves, leading to subjective findings. In conclusion, the teachers' skills were assessed by an examination that combined subjective questions with case analysis to gauge their performance and self-description in relation to cognitive powers. Individual and group evaluations relied on autobiographies or self-evaluation questionnaires that were filled out in accordance with predetermined topics. At the same time, an instructor used an assessment rubric and compared it to the student's progress throughout the teaching and learning process.
The Syntax of Old Catalan Clitics: “Llibre dels Fets”
Authors: Sentí Andreu , Bouzouita Miriam
Published: December 2022

Although the distribution of pronominal clitics in Old Catalan has been described in general terms (Fischer 2002; Batllori et al. 2005), there are no quantitative studies detailing the frequency of preverbal or postverbal clitics nor their diachronic evolution. The clitics appearing with verbs in the future and conditional tense (FC) are worth a separate mention, since these forms originate from periphrastic structures that involve an infinitive and the auxiliary verb habere, and which could appear as an analytic (dir-li he) or a synthetic form (li diré or diré-li). This paper describes the general clitic positioning and the one encountered with FC in order to verify the claim that they display parallel distributions, using a text from the 13th century, to wit Llibre dels Fets. This article analyses the pragmatic-syntactic environments in which the clitic are found, as well as the degree of grammaticalization and univerbation of the FC. Following previous work (e.g., Bouzouita & Sentí 2022), it is argued that the FC in Catalan appear to exhibit a more advanced degree of grammaticalization than the western languages of the Iberian Peninsula.

Sobre a noção de competência na educação e no mundo do trabalho: aproximações com a perspectiva de Paulo Freire
Authors: Hashizume Cristina Miyuki , Nogueira Carla Rossana De Araujo Torres
Published: December 2022

Dentro de um debate recente sobre as competências na educação, o presente ensaio tem como objetivo geral discutir o conceito de competência do professor, na perspectiva de Paulo Freire, e suas aproximações com o modo como vem sendo utilizado na educação (pelo Ministério da Educação) e no mundo do trabalho. Além disso, também se propõe a: i) apresentar o histórico e as diferentes conceituações do termo competência no mundo do trabalho e na educação; e ii) situar a perspectiva de Paulo Freire sobre competência docente, diferenciando-a do termo usado no mundo do trabalho ou mesmo em documentos oficiais do MEC. Enquanto metodologia de pesquisa, este ensaio apresentará os conceitos a partir de diferentes abordagens, cotejando relações, comparações e aspectos importantes para refletirmos o fazer docente. Como discussões provenientes do ensaio, percebemos certa incompatibilidade entre a visão técnica e instrumental de competência utilizada no mundo do trabalho ao ser comparada à proposta humanista, afetiva e dialógica de Freire. A visão mais técnica de competência parece não considerar saberes tácitos e relevantes para a formação cidadã de quem aprende, já que nem sempre tais saberes são mensuráveis ou produtivos. Nesse sentido, entendemos valer a pena discutir tais incompatibilidades no âmbito da prática escolar.
Laser-Guided Intraoperative Navigation in Total Ankle Replacement Surgery
Authors: Angthong Chayanin , Wattanasirisombat Kittipong , Manggala Yudha , Rajbhandari Prasit
Published: December 2022

Background. This study aimed to evaluate the effectiveness of laser-guided intraoperative navigation compared with the conventional method in determining the accuracy of coronal alignment setting in total ankle replacement (TAR).
Material and methods. Sixteen cadaveric ankles were randomly divided into two groups: laser-guided and conventional. Measurements were performed following coronal alignment setting in each ankle. All parameters were collected and compared between the two groups to determine the accuracy of coronal alignment setting regarding localization of possible mechanical axis (PMA) from each method. These parameters included the distance from the most medial point of tibial surface (TS) (intra-articular part) to the marked point that was possibly close to MA (MM-PMA).
Results. There were no significant differences between the two groups; however, there was a trend toward more neutralization of PMA in the laser-guided group in terms of MM-PMA distance (P = 0.19). In addition, the ratio of MM-PMA to TS demonstrated that the axis closer to the actual mechanical axis (AMA) with medial deviation was only 0.6% in laser group, whereas the axis caused increased lateralization from AMA in the conventional group, which was as high as 4.4% (P = 0.15).
Conclusion. Despite the limited sample size and insignificant differences of outcomes between the two groups, laser-guided intraoperative navigation provided higher accuracy of coronal alignment setting than the conventional method in TAR.
Evaluation of the Effect of Excess Synovial Fluid on Knee Joint Pain in Patients with Osteoarthritis
Authors: Olesiak Beata , Przedborska Agnieszka
Published: December 2022

Background. Joint pain and swelling are common symptoms of osteoarthritis. The fluid collects mainly in the suprapatellar bursa. Persisting excess synovial fluid accelerates the degeneration of joint tissues and contributes to limited mobility.
Material and methods. The study involved 150 patients with knee osteoarthritis whose ultrasound examination of the suprapatellar bursa showed > 4 mm of fluid in the transverse and longitudinal dimensions. A VAS analog scale was used to assess pain intensity in four settings: at rest, climbing stairs, walking on flat ground, and at night.
Results. There was no correlation in the study group between an excessive amount of synovial fluid in the suprapatellar bursa and pain severity during movement and at rest.
Conclusions. Excess synovial fluid in the suprapatellar bursa is not associated with knee joint pain at night, at rest, and when climbing stairs and walking on flat ground.
CAVITATION EROSION RESISTANCE OF HIGH-ALLOYED
Fe-BASED WELD HARDFACINGS DEPOSITED VIA SMAW
METHOD
Authors: Szala Mirosław , Hejwowski Tadeusz
Published: December 2022

In order to investigate the cavitation erosion (CE) resistance of high-alloyed ferrous hardfacings, the three
different deposits were pad welded by the shielded metal arc welding (SMAW) method. Consumable
electrodes differed in the content of carbide-forming elements, and pad welds were deposited onto the S235JR
structural. The CE tests, conducted according to ASTM G32 standard, indicated that hardfacings reveal
lower mass loss than the reference stainless steel AISI 304 (X5CrNi18-10). The hardfacings show increasing
resistance to CE in the following order: Cr-C < Cr-C-Mo < Cr-C-Mo-V-W. The reference steel revealed more
than twenty times higher material loss in the CE test than Cr-C-Mo-V-W hardfacing, which had outstanding
hardness (825HV0.3). The profilometric measurements and scanning electron microscopy investigations
showed large changes in valley and peak sizes of the roughness profiles for materials which displayed high
erosion rates. The erosion mechanism of the coatings can be classified as brittle-ductile and relies on cracking,
chunk removal of material, pits and craters formation, and deformation of fractured material tips and edges.
Hardfacing materials failed primarily due to brittle fractures with different severities. Specimen surface
degradation follows the changes in Ra, Rz, Rv, and Rp roughness parameters and well-corresponds to the
proposed roughness rate (RR) parameter.

Published: December 2022

Dynamics of weed density with a natural background of weeds in agrophytocenoses of sainfoin (Onobrychis sativa L.), birdsfoot trefoil (Lotus corniculatus L.) and alfalfa (Medicago sativa L.), pure grown (100%) and in mixtures with cocksfoot (Dactylis glomerata L.) (50:50%) and sown under a cover of pea (Pisum sativum L.) were tested in field trial in the Institute of Forage Crops, Pleven, Bulgaria. It was found that the weed infestance and species composition changed depending on the type of Ðµdificator. The species composition in weed associations was the highest in pure grown Lotus corniculatus L. In mixtures of Onobrychis sativa L. + Dactylis glomerata L. the highest weed infestance was recorded, and the lowest in Onobrychis sativa L. under cover of Pisum sativum L. Weed infestance in mixtures was lower as compared to pure grown swards, except Medicago sativa L. + Dactylisglomerata L. For the specific environment of study the highest part for annual dicotyledonous weed species (from 0.0 to 49.5%), followed by perennial dicotyledonous (from 3.7 to 58.2%) was obsereved. There was a strong variation in the percentage in agrophytocenoses of Convolvulus arvensis L. (from 0.0 to 11.4%), Sonchus arvensis L. (from 0.0 to 19.0%) and Erigeron canadensis L. (from 0.0 to 47.8%), whereas Matricaria recutita L. varied within narrow range (0.0 to 3.7%). The dependance allows to be used for developing more effective weed control systems in the studied forage crops and mixtures.

Published: December 2022

The impact of non-pesticide farmerâ€™s practice (Jind district, Haryana) adopted by a group of farmers on pestpopulation, natural enemies and yield parameters was studied and compared with Integrated Pest Management strategyand pesticide based farmersâ€™ practice within same villages where this group has implemented their pest managementstrategy in Bt cotton. Comparison of population per three leaves of sucking pests (average of 3 years) indicated lowestpopulation of whitefly (adult), jassid and thrips (nymph and adult) in IPM module (7.18, 3.37 and 7.17) followedby NIFP, non-insecticidal farmerâ€™s practice (7.70, 3.48 and 7.62) and FP, farmerâ€™s practice (9.64, 4.14 and 9.69)respectively. While studying the interaction among sucking pest and natural enemies it was interesting to note thatthe population, in both the cases, increased gradually and after attaining the peak activity there was a declining trend.Socio-economic studies also supported the above results. In present study, the mean seed cotton yield during 2015,2016, 2017 in IPM fields was 13.75, 22.45 and 17.42 q/ha, in NIFP it was 14.20, 18.10 and 13.70 as against 8.85,16.75 and 9.30 q/ha in pesticide based farmersâ€™ practice, respectively. The incremental benefit cost ratio in IPM fieldswas 2.87, 3.56, 3.81 and it was 4.09, 3.53, 3.66 in NIFP fields as against 1.60, 1.99, 1.82 in FP during 2015, 2016and 2017, respectively. It is evident that by adopting IPM strategy, sucking pests in Bt cotton can be successfullymanaged along with conservation of natural enemies with minimum application of insecticides.

Each and every village of North Bengal, have various types of jackfruit plants which needs to be known for their characteristics. Data were gathered from 60 jackfruit farmers of five villages of Cooch Behar and Alipurduar district through a structured interview schedule. The characteristics of jackfruit plant were assessed through IPGRI descriptor. The results showed that the jackfruit trees of North Bengal were dominated by irregular crown (40.32) and branch shape (39.24) with narrowly elliptical leaf blade shape (51.08), but broadly pyramidal crown shape and ellipsoid flake shape produced best quality vegetable as well as ripe fruit; whereas clavate fruit shape for vegetable and ellipsoid fruit shape for fruit was perceived best. The quality was assessed through matrix ranking of different parameters by group of farmers. On the basis of crown shape, most respondents preferred broadly pyramidal shape tree, acuminate leaf apex, ellipsoid fruit shape, cordate flake shape, yellow flake colour, ellipsoid seed shape and fruit position on the stem. Farmers opined middle time as best production time of jackfruit and pyramidal shape tree as best shape. Broadly elliptical leaf shape, acuminate leaf apex, obtuse apex shape and clavate fruit shape were the most preferred morphological characteristics. Although the farmers are the best evaluator but a scientific level evaluation is recommended for validation of the parameters for universal use.

Onion (Allium cepa L.) is one of the most important vegetable having year round demand and consumed fresh, cooked or processed. It occupies maximum area under vegetables in India. The consumption of onion has been associated with many health benefits. The genetic improvement work mainly focused on improving yield and there has been little effort on improving quality traits. Therefore, information on variability, heritability and trait association of phytochemicals content, antioxidant activity and bulb traits are lacking. The present study was conducted to bridge the gap and generate information on these aspects. A total of eight quality traits and four bulb traits were analyzed in 22 onion genotypes of five different skin colour. The genotypes were procured from diverse geographic region. The total soluble solids content (TSS), pungency, total phenol, flavonoids content, and antioxidant activities as estimated through CUPRAC and FRAP in the onion varieties varied from 10.13-16.65 Â°Brix, 4.67-12.28 Î¼mol Pyruvic acid/g FW, 740.67-1145.33 Î¼g Gallic acid equivalent/ml, 31.67 - 465.0 Î¼g Quercetin equivalent/ml, 2.23 - 5.14 Î¼mol Trolox/g and 1.60-4.63 Î¼mole Trolox/g, respectively. There was less difference between phenotypic and genotypic components of variance for pungency, total phenols, antioxidant activity and juice recovery, suggesting greater role of genotype in the expression of quality traits and better scope of improvement for these traits. The high heritability estimates (>75%) for bulb diameter, total phenols, flavonoids, pungency and antioxidant activity, and higher value of genotypic correlation co-efficient over phenotypic co-efficient supports greater role of genotype in the expression of quality traits. The high estimate of heritability and comparatively, low estimate of genetic advance and genetic gain suggest the role of both additive and non-additive gene action. Thus hybridization and selection would be the best strategy to improve quality traits in Indian onion genotypes. Future breeding attempt to develop onion varieties with higher health benefits should focus on medium sized varieties without compromising on yield.

A set of 53 wheat genotypes were evaluated for different quality and longevity related traits at NBPGR, New Delhi, India. The selected genotypes included both durum and bread wheat varieties released in India between 1970 and 2014, and bread wheat germplasm lines for comparison. Bread wheat varieties were good repositories for sedimentation value (SV), whereas, durum varieties for kernel hardness (KH) and germplasm lines for grain iron (Fe), zinc (Zn), and thousand kernel weight (TKW). Both vigor index-1 and 2 after controlled deterioration (VIACD-1 and VIACD-2) was highest for durum varieties followed by bread wheat germplasm lines and varieties. Therefore, seed longevity of durum varieties, bread wheat germplasm lines, and bread wheat varieties, respectively, was good, intermediate and poor. Broad-sense heritability was high for all the studied traits except germination percentage before controlled deterioration (GPBCD). Genetic advance as per cent mean (GAM) was high for all the studied traits, with the exception of moisture content (MC) and GPBCD. Six genotypes (IC 542394, IC 542391, IC 542416, IC 542431, IC 542426, and IC 542387) were good storers and also contained high Fe and Zn, which can be used in breeding programs to improve seed storability, and Fe and Zn content. Both intra species and inter species variability were observed for all the studied traits. The close association observed between Fe and Zn may help in improving both the traits simultaneously. Electrical conductivity (EC) of the seed leachates can be used as a surrogate trait for indirect selection for seed longevity of genotypes due to its significant negative association.

Reliable forecast of crop production before the harvest is important for advance planning, formulation and implementation policies dealing with food procurement, its distribution, pricing structure, import and export decisions, and storage and marketing of the agricultural commodities. Weather plays a very important role in crop growth and development. Therefore, model based on weather variables can provide reliable forecast. Weather variables used can be employed for crop production forecast by making appropriate models. In this study, a statistical model is used for crop yield forecast at different growth stages of wheat crop. This model uses maximum and minimum temperature, rainfall, morning and evening relative humidity during crop growing period. The forecast model was developed using generated weather indices as regressors in model. In order to select significant weather variables affecting the yield of crop least absolute shrinkage and selection operator (LASSO) as well as stepwise regression methodology is applied. The result of lasso gives a better result as compared to stepwise regression. The R2 of lasso and stepwise regression are 0.84 and 0.85, respectively. The mean square error (MSE) and root mean square error (RMSE) of Lasso regression were better than stepwise regression, which leads to improvement of crop yield forecasting. It can be inferred that for the data under consideration, lasso works better than stepwise regression for variable selection.

Published: December 2022

Transcriptome is the whole set of RNA molecules transcribed in a cell at a particular time under particular environmental conditions. Assessing the transcriptome and estimating the degree of expression of all genes under different conditions is a crucial step in understanding the dynamic processes that take place during development. In the present study, genes that play a major role in moisture stress were identified using high-throughput transcriptome sequencing analysis. High quality assembled transcripts of Cucumis melo var. agrestis control and stress samples were compared using BlastX with the protein databases available in the public domain. Gene Ontology (GO) analysis revealed that a total of 6263 and 6430 transcripts were assigned at least one GO term from control and stress samples, respectively. Changes of expression level in these transcripts for moisture stress tolerance were detected using RNA-seq mapping. Among stress responsive genes, a total of 122 genes were commonly expressed in both control and stress samples and 72 genes were highly upregulated in stress sample when compared to control sample.

An experiment was conducted at SKUAST-Kashmir during 2018–19 and field trials were conducted at Dryland Agriculture research Station of SKUAST-K and Saffron Research Station, Pampore, Jammu and Kashmir. Results of the present investigation revealed that application of vermicompost, biofertilizer alone or in combination were beneficial in increasing commercial production of saffron. It encouraged more blossoms, which directly influenced the yield of saffron in both locations. At the Dryland Agriculture Research Station, SKUAST-Kashmir application of Azotobacter @11.5 g + 115 g sand + recommended dose of vermicompost of FYM recorded highest number of flowers/plot (139), fresh flower weight (40.10g), and pistil weight (1.17g), followed by treatment level T6 (Azotobacter @11.5 g + 115 g sand + recommended dose of vermicompost of kitchen waste), similar T10 (Azospirillum @11.5 g + 115 g sand + suggested amount of FYM vermicompost). Similar trends in the results were seen at the Pampore Saffron Research Station. Significant changes between treatments for all the features were found in the analysis of variance for the floral and corm properties. For all features, with the exception of the number of flowers, flower weight, and corm weight, location impacts were also significant.

The crop residue application and the balanced fertilization with 3 major macronutrients mainly emphasizing on different potassium management practices significantly improve the yield attributing components of wheat crop. Likewise, the highest grain, straw and biological yield in wheat crop was observed with crop residue retention and the split application of 100% RDK (½ at basal + ½ top dress at 25 DAS). The maximum production efficiency and monetary efficiency was recorded under the crop residue retention. Among the potassium management practices the efficiencies were recorded maximum with the split application of 100% RDK (½ at basal + ½ top dress at 25 DAS). Hence, it can be concluded that for enhanced productivity and greater monetary efficiency, the crop residue retention and the split application of 100% RDK (½ at basal + ½ top dress at 25 DAS) could be a better management practice for better growth and development of wheat crop in a maize-wheat rotation. However, to have greater insights on the residue retention and potassium effects, the future research may focus on understanding water and nutrient release pattern in the soil profile, improvement in soil physical and mechanical properties, rhizospheric microbial dynamics and physiological effects on the wheat plants due to diverse residue management systems and potassium application protocols.
