Authors: Thongpance Nuntachai , Chotikunnan Phichitphon
Published: June 2023

This research aimed to design and construct an electric wheelchair with mecanum wheels that can move in any desired direction and speed based on the joystick controller. This represents a significant improvement over traditional electric wheelchairs, which are limited to linear movement in a single direction. The research contribution of this study is the development of an electric wheelchair with mecanum wheels that allows for improved mobility and independence for wheelchair users. The design includes a joystick controller and the use of an average filter to improve the processing of the joystick. This represents a significant improvement over traditional electric wheelchairs, which are limited to linear movement in a single direction. The design and construction of the electric wheelchair followed the ISO 2570-2555 guidelines and utilized Arduino DUE as the main processor for controlling the rotation of the wheels. The gain of speed and angle of the analog joystick were determined using the technique of finding the resultant vector to control the direction and speed of the wheels. The resulting electric wheelchair had a standard structure and was able to move in the desired direction and speed based on the movement of the joystick controller, demonstrating the success of the design and construction in achieving its objective. In conclusion, the development of joystick control for electric wheelchairs is important and allows for the creation of significantly novel and improved designs such as the electric wheelchair with mecanum wheels presented in this research.

Pregabalin has been used successfully as a component of multimodal analgesia regimen in a variety of surgical procedures. However, side effects such as dizziness and somnolence have been reported especially with doses ≥300mg. We hypothesized that using a lower cumulative dose of oral pregabalin in a divided dosing regimen would lower the incidence of side effects while providing adequate postoperative analgesia in patients undergoing lumbar spine fusion surgery.

Seventy adult patients of either sex of ASA 1-3, undergoing lumbar spine fusion surgery under general anesthesia were randomly divided into two equal groups. Group B received oral pregabalin 150mg one hour before induction and 75mg 2 hours after surgery. Group A received oral placebo at the corresponding time points. Pain was assessed using Visual Analogue Score (VAS) at extubation, 2, 4, 6, 12, 18 and 24 hours after surgery.

In the first 24 hours after surgery, the mean VAS scores were significantly lower in Group B (P0.001) at all time points while tramadol consumption for rescue analgesia (P0.001) and postoperative nausea (P0.013) and vomiting (P0.011) were significantly higher in Group A. Preoperative anxiety and sedation scores and postoperative incidence of dizziness and somnolence were comparable between the two groups.

Low dose oral pregabalin preoperatively and postoperatively using a divided dose regimen can be safely used to provide adequate postoperative analgesia with low incidence of side effects after lumbar spine fusion surgeries.

Published: June 2023

Maxillomandibular analysis relates the upper and lower jaw. The anteroposterior relationship of the maxilla and mandible through both angular and linear measurements is used to assess the sagittal jaw relationship.

To evaluate skeletal maxillomandibular changes in patients with class I malocclusion after extraction and non-extraction orthodontic treatment in the Solan population.

Cephalometric radiographs before and after treatment of 50 orthodontic patients were used in the study. The sample was divided into 2 groups, Group I (Class I, N=25, extraction cases) and Group II (Class I, N=25, non-extraction cases). Maxillomandibular parameters (ANB, Wits Appraisal, Harvold unit length difference, plane angle AB, convexity angle and MKG angle) were measured in both groups.

When comparing the two groups, significant changes were observed in the ANB angle (p=0.05), AO-BO (p=0.00), MKG angle (p=0.03) and convexity angle (p=0, 00). Conversely, Harvold (p=0.70) and AB plane angle (p=0.75) were found to be insignificant.

The result of the above study indicated that bone maxillomandibular changes in ANB angle, AO-BO, MKG angle and convexity angle can be observed in patients after extraction and non-extraction orthodontic treatment.

Published: June 2023

Dermatoglyphics is a study of the unique pattern in the skin of fingers, palms, soles, and toes. These dermatoglyphics has played an important role in various fields like forensic medicine, genetics, and anthropology.

Sir Francis Galton stated that an individual’s dermal pattern remained constant throughout their lifetime. Many studies have suggested the possible relation between dermatoglyphics and occlusion.

Studies have suggested that dermatoglyphics could be used as a tool to identify the underlying skeletal malocclusion. As the dermal pattern and oral structures develop together, the genetic information in the dermal pattern could be used to assess the different types of skeletal malocclusions.

Hence, the study was aimed to compare and evaluate the correlation between dermatoglyphics and class II skeletal malocclusion in horizontal and vertical growth patterns. The total of 50 samples were taken and divided into horizontal and vertical growth pattern consisting of 25 samples each. The dermatoglyphic pattern between the right and left hand and the pattern such as arches, loops, and whorls were evaluated.

The data was analyzed by Kolmogorov – Smirnov and Shapiro Wilk test. There was a statistically significant association between class 2 malocclusion and the dermatoglyphic pattern.

Published: June 2023

The correction of skeletal malocclusions in orthodontics has always been a contest for clinicians, especially in non-growing individuals, and often necessitates the distalization of maxillary or mandibular skeletal bases. To accomplish this, diverse treatment modalities have been employed by researchers, and the most recent one is the use of extra-alveolar bone screws such as Infra-zygomatic Crest (IZC) implants. Unlike conventional methods such as extraction and orthognathic surgery, this technique is an effective and efficient treatment alternative for predictable total arch distalization in borderline surgical cases, without interfering with the root movements and with minimal dependence on patient compliance. For achieving the displacement of teeth in a bodily controlled manner, an appropriate direction and magnitude of force must be carefully chosen. Therefore, this case report attempts to measure the amount and pattern of maxillary molar distalization using Infra-zygomatic Crest (IZC) implants with long power arms as a workable treatment option, in an 18-year-old female patient with a skeletal Class II pattern, with no extra mini-implants in the anterior region for intrusion.
An easy way to treat buccal canine malocclusion: A case report
Authors: Azad Huma , Ibrahim Nabeela , Anjum Arbab , Akhtar Farheen
Published: June 2023

An ectopic tooth is one that is erupting in an aberrant route, whereas an impacted tooth is one that has failed to fully erupt into the oral cavity within its expected developmental time period and can no longer be expected to do so. The majority of canine eruption abnormalities occur in one of two directions: palatal or buccal displacement from the usual eruptive location 2. Permanent maxillary canine impaction or ectopic eruption affects about 1-2 percent of the general population. Canines that are palatally displaced are twice as common as those that are buccally placed. Buccally displaced canines, on the other hand, are very prevalent in practice and their etiology is related to a deficient dental arch perimeter 3,4. So, the purpose of this report is to show a case of a 15-year-old male with ectopic maxillary canines who was treated by extracting the four first premolars, using segmental T loops for retraction of ectopic canines. The goals were met at the end of treatment with optimal aesthetic balance and excellent occlusal connections, resulting in great long-term stability.

Published: June 2023

There has been increase in the treatment modalities for non-surgical Class II malocclusion. This has resulted in orthodontists becoming more vigilant with extraction treatment plans and exploring possible non-extraction treatment approaches. Maxillary molar distalization is one such method. The maxillary molar is distalized to create space and helps in solving the malocclusionMany appliance were used for the distalization of molars over the period of time. Both intra-oral and extra-oral methods are present. The extra oral appliance includes headgear and heavy elastics; whereas intra oral appliance include distal jet, jones jigs, pendulum appliance, k-loop, fixed functional appliances, magnets, ACCO appliance and use of TAD’s. Thus the use of IZC implants has been effective in distalization of molars.
Genotoxicity of Beta-Sitosterol, Betulinic Acid, Biochanin A, and Ursolic Acid, Potential Anthelmintic Phyto-Compounds
Authors: Mishra Vijaya , Yadav Arun K. , Soren Amar Deep
Published: June 2023

Beta-sitosterol, betulinic acid, biochanin A and ursolic acid are known to possess anthelmintic properties. This study was undertaken to assess the genotoxic potentials of these phytocompounds in albino rats. Animals were orally administered with 1 and 10 mg/ml of the above phyto-compounds for a period of 14 days. All the animals were subjected to mitotic arrest before sacrifice and then bone marrow cells were collected from both the femurs and processed to observe the chromosomal aberrations. The results revealed that ursolic acid induced the maximum number of statistically significant abnormalities (p ≤ 0.05) followed by betulinic acid and biochanin A. Beta-sitosterol was found to be the safest of all the tested phytocompounds as far as chromosomal abnormalities in short term oral studies are concerned as it did not lead to major changes at genomic level. Although these phyto-compounds are considered potential anthelmintics, their long-term use may cause genotoxic effects to the users.

Published: June 2023

Background: Despite the high prevalence of proximal humeral fracture, one of the most prevalent osteoporotic fractures, its treatment has always been challenging. Here we are going to determine the factors that affect the outcomes of such fractures.
Methods: The present retrograde cohort study was conducted in a tertiary trauma center during 2015-2020. The Neer classification was used to classify fracture severity. Patients’ functional status was measured using the Disabilities of the Arm, Shoulder, and Hand (DASH) questionnaire and Constant-Murley Score (CMS). Patients were selected thorough purposive sampling method.
Results: The study participants included 70 patients with a mean age of 50.47 ± 16.73 years. The 3 treatment options of open reduction and internal fixation (ORIF) (39 cases; 52%), hemiarthroplasty (3 cases; 4%), and conservative treatment (33 patients; 44%) were considered. Malunion was the most prevalent complication in the study population (9 cases; 12%). The mean DASH score of the participants was 29.91 ± 20.43. The mean DASH score in patients of over 65 years of age was higher than in those under 65 years (36.97 vs. 28.14; P = 0.136). The score in patients underwent surgery (ORIF and hemiarthroplasty) showed a significant difference compared to the patients who were treated non-surgically (P = 0.050). The mean CMS of participants was 64.09 ± 22.71. The mean age of patients classified as “poor” was significantly higher than the “excellent” group (P = 0.041). The mean visual analogue scale (VAS) score of the participants was 2.80 ± 2.49. The VAS score was significantly higher in patients with more severe fracture based on the Neer classification (P = 0.050). 
Conclusion: The present study results showed the significant effect of age, fracture severity, and underlying disease on the proximal humeral fracture outcome. A longer follow-up period was observed in patients who had better functional outcomes. However, more studies with larger sample size are required to evaluate proximal humeral fracture outcomes in order to help us to improve outcomes and reduce complications.

Published: June 2023

The background of this research is students’ low mathematical problem-solving ability. The purpose of this study was to determine the efforts to build mathematical problem-solving abilities of junior high school students, especially in the number operations material caused by the lack of attention and involvement of students in the learning process, students’ difficulties in understanding story problems related to contextual problems, and students who were less active and creative. in constructing problem-solving ideas. Therefore, we need a learning model that can build students’ mathematical problem-solving skills, namely the problem-based learning model. This research was conducted at SMPN 25 Malang as classroom action research (CAR) which refers to the MC Taggart learning model which was carried out for two cycles. The study was carried out on 31 students of class VII.C. The results of this study indicate that the test results of students’ mathematical problem-solving abilities have changed for the better from cycle I to cycle II, where in cycle II the average score has reached 76 and the criteria for completeness have exceeded the mastery limit, which is 87.10%. In this case, it can be concluded that the application of the problem-based learning model can build the mathematical solving abilities of students in class VII-C of SMPN 25 Malang.

Published: June 2023

If starting school at the age of seven was considered sufficient in the past, many parents now start their children at the age of toddlers. As a result, the teacher’s role is critical because it serves as a substitute for parents. Preschool teachers must be able to monitor children’s growth and development in addition to teaching because it affects their future. Parents and teachers must pay adequate attention and affection, educate, guide, and set a good example. Students collaborate in groups to achieve the common goal of each idea through collaborative learning. This aligns with the skills required in the 21st century, namely the 4Cs (creative thinking, critical thinking and problem-solving, communication, and collaboration). The research method employs descriptive qualitative research to describe early childhood teachers’ perceptions of collaborative learning’s current implementation. The participants in the study were 23 teachers who had implemented collaborative learning.

Background & Aim: The trans-theoretical model suggests that stage-matched interventions improve the effectiveness of behavior changes such as quitting. This study aims to examine the effect of stage-matched smoking cessation educational intervention based on the trans-theoretical model using motivational interviewing on Egyptian males' knowledge, stage movement, and smoking cessation rate.
Methods & Materials: A randomized controlled trial was conducted in the main building of Damanhour University, Egypt. The participants were selected using simple random sampling (N=165), then allocated to both experimental (N=82) and control (N=83) groups using the randomization block technique. Data was collected using a structured interview schedule. The instrument contained five parts: Personal Characteristics and Smoking data, Fagerstrom Tolerance Questionnaire, Tobacco Cessation Readiness Scale, Smoking Knowledge Scale, and trans-theoretical Model constructs questionnaire. The experimental group received ten months of educational intervention using face-to-face and phone-based motivational interviewing.
Results: A significantly higher stage movement was revealed among the experimental group post-intervention (80.5%); 35.4% transitioned to the preparation stage, 32.9% were in the action stage, and 12.2% were in the maintenance stage. According to the ANCOVA test, significant negative mean differences post-intervention was achieved for nicotine dependence and decision pros (P=0.000) with a large effect size (η2=0.341, η2=0.503). However, significant positive mean differences were proved for other variables (knowledge, tobacco cessation readiness, and TTM constructs) (P<0.05) with a large effect size (η2>0.14). Stage analysis revealed significant mean differences in most studied variables, where the action stage had the highest significant mean improvements (P<0.05).
Conclusion: The trans-theoretical model-based educational intervention using motivational interviewing effectively improves smoking knowledge and facilitates quitting with successful stage movement among Egyptian male smokers.

Published: June 2023

Background & Aim: Napping is one of the evidence-based countermeasures to fatigue and decreased alertness during night shift work. We aimed to understand night shift nurses' napping practices and study the effectiveness of different nap lengths on sleepiness, fatigue, well-being, and the quality of nursing care.
Methods & Materials: A comparative descriptive design was used. Data were self-reported by 305 nurses using the Questionnaire on Night Shift Napping Practices, the Karolinska Sleepiness Scale, the Fatigue Visual Analog Scale, the Everyday Feeling Questionnaire, and the Quality of Nursing Care Questionnaire. Data collection was done over 4 months between August and November 2022. Frequency tables, Mean, and standard deviation were used to describe data, and One-way analysis of variance (ANOVA) was used for means comparisons.
Results: About 40% of the nurses reported that they took naps during their night shifts. The majority (82.92%) reported that they napped for more than 45 minutes (N= 305). Napping was found to significantly reduce sleepiness (P= 0.002) and fatigue (P= 0.001) and improve the quality of nursing care (P= 0.03). The group who napped for more than 45 minutes reported significantly reduced levels of sleepiness (P= 0.02) and fatigue (P= 0.01) when compared to the group who either didn’t nap or napped for less than 45 minutes.
Conclusion: This study suggests that implementing nap interventions for nurses on night shift can be an effective method to reduce sleepiness and fatigue, and improve patient care.
Near-death experience: A concept analysis
Authors: Kaleem Azeem
Published: June 2023

Background & Aim: The incidence of near-death experience is not a novel phenomenon since human history. However, with healthcare technological advancement, near-death narratives have been reported in a greater number of critically ill patients as well as in the general community. Therefore, healthcare professionals must recognize the concept of near-death experiences and provide relevant care to their patients. Unfortunately, healthcare providers, especially nurses, do not have sufficient knowledge regarding near-death experiences, hence, to clarify the concept and its importance for better patient-care outcomes via this concept analysis.
Methods & Materials: The understanding of the near-death phenomenon is employed through the framework of Walker and Avant's concept analysis. The study familiarizes the concept via its definition, origin, significance, characteristics, antecedents, and consequences of near-death experiences. This was achieved after deeper exploration and analysis of the concept through an extensive literature search. Furthermore, multiple cases are provided as exemplars to recognize the concept.
Results: Near-death experience is defined as a profound conscious experience encountered by the individual. The characteristics of near-death experiences are based on cognitive, affective, paranormal, and transcendental components. Following the experience, the individuals undergo a transformational change in their lives. However, individuals with near-death experiences require facilitation and support from healthcare workers, especially nurses, for the early integration of near-death experiences.
Conclusion: The understanding of the concept of near-death experience enables nurses to provide relevant nursing interventions. Such interventions promote positive well-being in the individuals' lives through their near-death experiences.

Published: June 2023

Background & Aim: Adopting self-care behaviors is considered an important factor in the prevention of COVID-19. Therefore, this study was conducted to investigate Self-Care Behaviors Related to COVID-19 among Iranian elderly with and without a history of infection.
Methods & Materials: This descriptive-correlational study was conducted on 324 elderlies in Iran in 2021. Eligible seniors were selected by convenience sampling and placed into two groups:  the elderly with a history of COVID-19 and the elderly without it. The data collection tools included the demographic form and the questionnaire on self-care behaviors during the COVID-19 pandemic. Data analysis was done with SPSS software version 25 using descriptive (frequency and percentage) and inferential statistics (Mann-Whitney u-test and independent t-test).
Results: 165 men (50.90%) and 159 women (49.10%) participated in this study. The mean age of the participants was 70.60 ± 8.73. The results showed that there was a statistically significant difference between the self-care behaviors of the elderly with a history of COVID-19 and those without it; the elderly with a history of COVID-19 had more favorable self-care behaviors (p<0.001).
Conclusion: A history of COVID-19 results in better self-care behaviors. It can be justified by constructs of the health beliefs model, including perceived susceptibility, severity, and treatment. Therefore, it is necessary to improve self-care behaviors by using the experiences of infected elders in health education to influence the above mention constructs.

Authors: Suarnianti Suarnianti , Haskas Yusran
Published: June 2023

Background & Aim: Nurses worldwide face serious challenges in dealing with infectious diseases. A transmission prevention model is expected to be a strategy to overcome these challenges. To date, most of the available models are in the form of disease prevention models primarily implemented to detect infections. In contrast, only a few models are implemented to improve disease transmission prevention behavior, especially in nurses. This study aims to find a model of infection transmission prevention adopted from the aids risk reduction model.
Methods & Materials: This study was an analytic observational study and employed a cross-sectional approach. This study was conducted in two hospitals in Makassar City and involved 123 respondents. The data were analyzed using multiple linear regression tests.
Results: This study finds that there is a correlation between organizational factors and nurses' commitment (b=.268) (p=.003); there is a correlation between self-justification and nurses’ self-labeling as at-risk individuals of contracting the disease (b=-.180 )(p=.049); there is a correlation between labeling and actions to reduce the risk of disease transmission (Enactment) (b=.255)(p=.001); there is a correlation between nurses' commitment and enactment (b=.651)(p=.001).
Conclusion: The risk reduction model could represent the nurses' disease transmission prevention behavior.

It is widely accepted that the field of obstetrics and gynecology is one of the most challenging specialties, due to the high expectations regarding patients' safety, irregular working hours and great sense of responsibility surrounding it. Medical errors among obstetricians, midwives and nurses consist a significant problem which arises in this field. Numerous factors have been shown to affect the occurrence of obstetric errors. Not only is raising awareness of the potential causes of high importance, but it can also contribute to the reduction of adverse events and unfortunate patient outcomes.

Published: June 2023

A pesquisa tem como objetivo mapear a literatura sobre a divulgação de informações financeiras relacionadas aos riscos climáticos. Para isso, realizou-se uma revisão sistemática da literatura apoiada na análise bibliométrica. Foram analisados 55 artigos, coletados das bases de dados Web of Science e Scopus. Este artigo contribui com a análise sistematizada de um tema que está cada vez mais presente na rotina das organizações e tem sido o foco das discussões a partir do Acordo de Paris de 2015. O estudo revelou que a disseminação do conhecimento sobre o tema é recente, mas evidencia importantes achados, como a falta de padronização dos indicadores e mecanismos robustos de acompanhamento de desempenho ambiental organizacional, destacando a importância de novos estudos. A transparência nas informações disponibilizadas também é um tema relevante no campo de discussão para o aperfeiçoamento dos métodos, assim como a falta de regulamentação para a obrigatoriedade de divulgações financeiras sobre os riscos climáticos. Lacunas de pesquisa foram evidenciadas, sendo divididas em indicadores, gestão de riscos, qualidade das informações, ativismo dos investidores e regulamentação. Cinco temas principais emergiram da revisão com ênfase aos estudos relacionados ao alinhamento das organizações às orientações da TCFD. Proposições foram sugeridas em cada um dos temas discutidos. A investigação constatou que houve um progresso relacionado a transparência na divulgação dos dados das empresas, porém apenas isso está muito longe de ser um resposta adequada aos desafios para o alinhamento das finanças relacionadas ao clima.

Published: June 2023

The problem of constructing the approximately optimal Bayesian algorithm of filtering the output signal for a linear stochastic dynamical system is solved. Non-linear mixture of the output signal and of the multiplicative interference was measured. This interference is a continuous-valued random process with the unknown distribution law within the given limits of [c(1), c(2)], c(1) > 0, c(2) > 0, and in the frequency range of [0, ∆ω]. The filtering algorithm is synthesized by the approximately optimal signal estimation method based on the theory of systems with random jump structure and the method of two-time parametric approximation of the phase coordinates probability distribution. The method consists in approximate replacement of the unknown probability densities of phase coordinates by the known distribution laws with the unknown mathematical expectations and covariances determined as a result of solving the problem. The proposed approximate-optimal filtering algorithm is based on replacement of the continuous-valued multiplicative interference by a random jump process, i.e., Markov chain with two states c(1), c(2) and equal intensities of transitions from one state to another q′ = 2∆ω. Conditional probability densities of the output signal for fixed states of the Markov chain c(1), c(2) are approximated by gamma distributions that depend on mathematical expectations and variances of the x(t) signal at the fixed c(1), c(2) and measurements x(t) in a mixture with the Markov jump interference. An example of constructing an algorithm for evaluating the distance from an aircraft to the object based on object irradiance measurement by the infrared direction finder was considered. Irradiance was equal to the radiation strength ratio to the square of the distance. Radiation strength, i.e., multiplicative interference, was the random process with unknown continuous distribution in a limited range. The approximate-optimal filter was constructed for distance evaluation by replacing this process with a two-state Markov chain and approximating the distance probability density by the Rayleigh distribution

Authors: Kim K.H. , Park B.K.
Published: June 2023

Background: Odors from livestock facilities are mainly caused by livestock manure. This causes deterioration of the health of the farm workers and the productivity of livestock. Complex additives with different actions are required to effectively reduce fecal contaminants. This study was conducted to investigate the effects of combined odor reducing additive (CORA) supplementation on the odor emission of feces and the growth performance of Hanwoo steers. Methods: Ninety-six Hanwoo steers were randomly assigned to the following four groups: control group fed with CORA-unsupplemented formula feed; T0.05 group fed with 0.05% CORA-supplemented formula feed; T0.1 group fed with 0.1% CORA-supplemented formula feed and T0.2 group fed with 0.2% CORA-supplemented formula feed. The CORA comprised 88% zeolite, 3% Bacillus licheniformis, 3% Bacillus polyfermenticus and 6% saponin. Result: The fecal NH3-N gas emission was significantly lower in the T0.2 group than in the control group (P less than 0.05). The fecal H2S gas emission at 20 d of incubation was lower in the T0.2 group than in the control group (P less than 0.05). The fecal NH3-N concentration was lower in proportion in all the groups with different supplementation levels of CORA than in the control group after 7 d of incubation (P less than 0.05). The number of fungi in feces was lower in the treatment groups than in the control group and the lowest was for T0.2 group (P less than 0.05). The results of this study indicated that CORA supplementation can reduce the emission of harmful gases (NH3-N and H2S) and odor-causing substances in feces and inhibit mold growth.

Background: Rice is a major cereal crop and a staple food for more than half of the world’s population. Frontline demonstrations on rice with improved rice varieties, production and protection technologies were organized to increase crop productivity and profitability of farmers. Methods: Frontline demonstrations (FLD) on rice with recently released short-duration varieties, RNR 15048 and KNM 118 and proven technologies in crop production and crop protection were conducted on farmer’s fields by Krishi Vigyan Kendra, Kampasagar, PJTSAU, Nalgonda, Telangana during the kharif seasons of 2017-2019. Result: Higher mean yield (6314.0 kg ha-1) was obtained in improved varieties RNR 15048 and KNM 118 with the latest agro-technologies such as seed treatment with carbendazim @ 1g lt-1 of water, seed rate @ 62.5 kg ha-1, application of carbofuran 3G in rice nursery, recommended dose of fertilizers in the main field, need-based plant protection practices such as formation of alleyways, installation of pheromone traps at 25 DAT, application of carbofuran 3G @ 25 kg ha-1, spraying of Pymetrozine @ 250 g ha-1 to control brown plant hopper in rice against the local check MTU 1010 (5823.0 kg ha-1) in the farmers’ practice and on an average 8.3% superiority was observed over the farmer’s practice. Yield contributing traits like plant height (85.3 cm), number of tillers m-2 (343.3), effective tillers m-2 (319.0), panicle length (21.0 cm) and straw yield (4904.3 kg ha-1) were maximum in improved practice against the farmers’ practice, except test weight (24.7 g). Improved practices resulted in higher gross returns (Rs. 1, 10, 890 ha-1), net returns (Rs. 61,675 ha-1) and B: C ratio (1:2.3) than the farmer’s practice.
