Published: March 2024

Grain yield is complex traits, influenced by genetics and the environment, posing challenges for prediction. The goal of the present study was to identify key traits that contribute to rice yield by applying seven statistical techniques. The study examined twenty-four rice genotypes following a randomized complete block design (RCBD) with three replications. Pearson's correlation analysis revealed several traits exhibiting significant positive correlations with grain yield (r≥0.60), including thousand-seed weight (r = 0.63), filled seeds/panicle (r = 0.74), and number of panicles/m2 (r = 0.70). Multiple linear regression identified significant predictors as the number of panicles/m2 (R=0.01) and thousand-seed weight (Coefficient=0.12). Stepwise linear regression suggested key yield indicators viz. the number of panicles/m2 (R=0.01), filled seeds/panicle (R=0.02), thousand-seed weight (R=0.11), and panicle length (R=0.13). Bayesian linear regression found similar traits with a Bayes factor of 995.2 and an R-squared value of 0.77. Exploratory factor analysis showed grain number/panicle, filled seeds percentage, filled seeds/panicle, thousand-seed weight, grain width, and panicles/m2 are highly influenced grain yield and explained 61.9% total variance. Principal components analysis revealed the first three components explaining 79.1% of yield variation, with thousand-seed weight, grain width, and panicle number/m2. Path analysis demonstrated the number of panicles/m2, filled seeds/panicle, thousand-seed weight, and panicle length have large and significant positive direct effects on grain yield. These findings strongly suggest that selecting breeding materials with traits like high panicle density/m2, larger panicle size, more filled seeds/panicle, and higher thousand-seed weight, can significantly increase the rice yield.

This study focused on follow-up the changes in the quality and shelf life of dried spotted snakehead (Channa punctatus) products under modified atmosphere packaging (MAP) conditions processed using an improved solar dryer. Four packaging methods, such as, air pack (sealed without changing atmospheric gas), MAP-1 (100% N2), MAP-2 (50% CO2 & 50% N2) and MAP-3 (40% CO2, 30% O2 & 30% N2) were employed and kept at room temperature. Biochemical and microbial analyses were performed at 15-days intervals over a period of 4 to 5 months of room storage. Moisture of the dried products remained within acceptable limits considering the salt content of the products. Observations revealed comparatively lower pH, total volatile base nitrogen (TVB-N), and thiobarbituric acid reactive substance (TBARS) values, none of which crossed the acceptable limits in any of the packaging conditions. Total viable counts (TVC) exceeded the permissible level of 5 log CFUg-1 after 75 days for air pack and MAP-1 samples and 120 days for MAP-2 and MAP-3 samples. Based on the bacterial counts, the shelf life of dried spotted snakehead products was estimated at approximately 75 days for air-pack and MAP-1 samples and 120 days for MAP-2 & MAP-3 samples. Therefore, MAP-2 (50% CO2 & 50% N2) & MAP-3 (40% CO2, 30% O2 & 30% N2) were identified as effective packaging methods for extending the shelf life of dried spotted snakehead products.

Published: March 2024

Okra is a ubiquitous annual vegetable for its taste and dietary value. The field experiment pursued the effects of vermicompost and inorganic fertilizer on the growth and production of okra. We used three types of fertilizer in this study: control (T3); vermicompost (T1) [5 t/ha]; inorganic fertilizer (T2) [Urea: 80 kg/ha, TSP: 60 kg/ha, MoP: 60 kg/ha]; and two verities of okra, Super Shomy F1 (V1) and BARI Dherosh-1 (V2). Our experiment has some parameters like the height of the okra plants, the length, weight, and diameter of a single pod, the number of leaves, the length of the petiole, the length of the leaves, the days to first flowering, the total pods per plant, the weight of the pods per plant, and the total yield (ton/ha) that are related to vermicompost and inorganic fertilizer. Results showed that all growth and yield parameters were highest in the Super Shomy F1 variety compared to BARI Dherosh-1. Among fertilizer management treatments, vermicompost recorded significant results over inorganic fertilizer on all parameters except leaf number and days prior to first flowering. The control group yielded the lowest outcome across all parameters. As part of the fertilizer management treatment's interaction effect with variety, the highest yield (16.37 t/ha) was measured in V1T1 (Super Shomy F1 × vermicompost), followed by V1T2 (14.50 t/ha), and V2T1 (12.50 t/ha). V2T3 (BARI Dherosh-1 × control) showed the lowest performance (5.4 t/ha). The experiment suggests that applying vermicompost encourages okra to grow and yield more.

Every year huge quantity of mangoes are lost due to lack of proper postharvest storage condition. The study was carried out to minimize the postharvest loses and extend shelf life of mango fruit by using botanical extracts. The popular mango variety ‘Amrapali’ was used as experimental materials for the study. The study comprised of 6 different botanical extracts as treatment. The treatment combinations were T0: Control (no botanical extract), T1 = Neem extract, T2 = Biskatali (Water Pepper) extract, T3 = Neem + Biskatali (Water Pepper) extract, T4 = Ghagra extract, T5 = Biskatali (Water Pepper) + Ghagra extract. The maximum shelf life (15.58 days) was observed from T1 treatment, whereas the minimum shelf life (9.00 days) was recorded from T0 treatment in Amrapali mango. At 3, 5, 7 and 9 days after harvest (DAH), the most firmness score (1.70%, 3.48%, 4.53% and 5.28% respectively) was found from T0 treatment in Amrapali mango, whereas the lowest firmness score (1.01%, 2.05%, 3.23% and 4.11% respectively) was observed from T1 treatment. At 3, 5, 7 and 9 days after harvest (DAH), the highest weight loss (3.06%, 5.92%, 8.63% and 9.55% respectively) was found from T0 treatment in Amrapali mango, whereas the lowest weight loss (2.10%, 4.07%, 7.12% and 8.14% respectively) was observed from T1 treatment. At 5, 7 and 9 days after harvest (DAH), the extreme disease incidence (27.77%, 61.11% and 100.00%, respectively) was recorded from T0 treatment and the moderate disease incidence (0.00%, 11.11% and 20.83%, respectively) was observed from T1 treatments. So, consideration of shelf life and quality treatment T1 as stored in neem extract treatment were superior on other botanical treatment for ‘Amrapali’ mango. The results clearly showed that the neem extract proved as the best choice for the extend shelf life and quality of mango.

Quinoa is a potential crop for its use as human food and animal feed due to the high nutritional grain and quality forage. However, quinoa’s growth, yield and quality are affected by many factors. The study was aimed to evaluate the variability of eight quinoa cultivars over two years for phenology, yield and attributing traits, and also for nutritional quality of grain. The experiments were arranged in Randomized Complete Block Design with three replications. Significant variations were exhibited among the cultivars for all studied traits. Three cultivars, 5-Red, 40-Red and 45-Red, had the highest potential growth performance, while Cahuil cultivar had the highest grain yield. Both Cahuil and Isluga cultivars exhibited more stable and higher contents of nutrient composition than other cultivars. Significant positive correlation were observed for grain yield with yield attributing traits, and for forage yield with most of the growth traits. No negative correlations among grain quality traits were observed, implying easier improvement for quinoa grain quality. The first two principal components in PCA (principal component analysis) explained 77.39% of the total variability. Based on forage yield, grain yield and nutritional quality over two years, 40-Red cultivar was selected for grain production and forage yield purposes, and Cahuil cultivar was selected for high grain yield and nutritional quality.

Morphometrics are vital quantitative features for production performance and can affect body size. Hippocampus abundant transcript 1 (HIAT1) gene belongs to the major facilitator superfamily that has specific association with growth related traits in mammals including goat. This study was conducted to investigate possible association between 15-bp insertion/deletion (indel) polymorphism of HIAT1 gene and morphometric traits in different goat populations of Bangladesh. A total of 288 blood samples were collected from Black Bengal goat (BBG), Jamunapari (JP) and Black Bengal cross (BBC) populations. One pair of primer was used to amplify HIAT1 gene fragment that harbored 15-bp indel polymorphism. PCR amplification detected insertion (II), deletion (DD) and heterozygous (ID) genotypes. The II, ID, and DD genotype frequencies were 0.16, 0.44, and 0.40 respectively in BBG populations where the corresponding genotype frequencies were 0.00, 0.47, and 0.53 in JP and 0.11, 0.40, and 0.49 in BBC goat populations. Overall, both the DD and ID genotypes were predominant than II individuals in the studied goat populations. The studied morphometric traits differed significantly among the three goat populations (P<0.01) as well as in different coat color variants of BBG (P<0.05). However, rump width (P<0.001) and rump length (P<0.01) were significantly associated with 15-bp indel genotypes in BBG population and wither height and rump height were significantly (P<0.01) associated in BBC. In conclusion, this study revealed the exitance of 15-bp indel polymorphism in the studied goat populations and its influence on some morphometric traits was found.

Abstract (286)
Terminal heat stress is a key constraint in wheat cultivation and its impact is anticipated to increase in the current context of climate change. Heat stress poses a serious threat, especially during the reproductive and grain-filling stages in wheat that can causes a significant reduction in yield. The current research was carried out to assess the nature of genetic variability and the relationship between yield and yield attributing traits of 30 different wheat genotypes grown under terminal heat stress and also to isolate the best performing genotypes based on stress tolerance indices. The highest estimates of PCV and GCV were observed for plant height (67 and 65, respectively). Most of the traits showed high heritability, among which days to germination (98.45%), plant height (96.51%), total grain per plant (99.71%) exhibited the highest. The highest genetic advance was estimated in filled spikelet per spike (97.37%). Total grain weight and hundred grain weight had strong positive correlation with yield per plant. The characters viz., plant height, chlorophyll content, no. of tiller per plant, days to 50% flowering, filled grain, hundred grain weight, flag leaf length, days to booting, total grain weight had a positive direct effect on grain yield. In this experiment, SADH-2, DSN-76, NK-5, NE-3, SA-2 had the lowest value of TOL which indicated that they had high tolerance towards heat stress. The highest value of YSI was observed in DSN-76, NE-3, BAW 1008, NK-5, SADH-22 which indicated that they had lower yield reduction and higher yield stability under heat stress. The optimum sowing date showed better performance for all the examined traits compare to heat stress condition. The identified genotypes hold promise for future breeding programs aimed at developing wheat varieties resilient to terminal heat stress.

Abiotic stresses like drought frequently reduce the productivity of wheat, an important global cereal crop farmed for food, feed and raw materials. Therefore, attempt should be made to search for drought tolerance in wheat cultivars. The purpose of the study was to look into how morphological features thirty wheat genotypes were affected by PEG-induced physiological drought stress at germination and seedling stages. Seven morphological traits viz germination percentage, root number, shoot length, shoot fresh weight, root fresh weight, shoot dry weight, root dry weight was measured at 14 days of stress condition and significant variation was observed in most of the traits due to genotypes, treatments, and genotype × treatment interaction. Drought stress causes a significant decrease in almost all morphological traits during the germination and early seedling stages, and among the genotypes SA-2 and SA-3 were performed best. A positive significant correlation was found among the morphological traits, except for fresh and dry weight of shoot. Principle Component Analysis (PCA) showed that only first two PCs were significant and had eigenvalues > 1. The first two PCs cover the 72.78% of total variation. Multi Trait Stability Index (MTSI) showed that SA-3, SA-2, BL-1020 and PV-79 performed well in drought stress condition and these genotypes can be further used for breeding program to develop drought tolerant high yielding wheat variety.

Authors: S Karthik , Taori Pragya , Muraraiah Sushma
Published: March 2024

Background: Psychotropic polypharmacy involves the concurrent prescription of two or more psychotropic medications to a patient. The prevalence varies from 13% to 90%. Polypharmacy may increase the effectiveness of treatment but can increase the chances of adverse effects, drug interactions, cost, and lower adherence.

Aim and Objective: The aim and objective of the study are to assess the frequency and the factors associated with psychotropic polypharmacy.

Materials and Methods: A cross-sectional study was conducted among adult patients attending a psychiatry clinic in a tertiary care center. The study was initiated after obtaining clearance from the institutional ethics committee and informed consent from the patients. Detailed demographic, disease, and drug data were collected through interviewing and reviewing the case record forms of patients. The Chi-square test and binary logistic regression were used to determine the factors associated with polypharmacy.

Results: Of the 125 study participants, 87.2% were aged between 20 and 60 years. The overall frequency of polypharmacy was 68.8%. The frequency of polypharmacy was 100% in bipolar disorder (BPD), 85.2% in psychosis, 81.3% in anxiety, 64.7% in depression, and 52.4% in alcohol dependence syndrome. 70% of BPD and 37% of psychosis patients had antipsychotic polypharmacy and 19% of anxiety patients had selective serotonin reuptake inhibitor polypharmacy. 11% of psychosis patients had polypharmacy of sedatives. On regression analysis, the factors significantly associated with psychotropic polypharmacy were the primary diagnoses of the patient, i.e., psychosis and anxiety.

Conclusion: More than half of the patients were noted to have psychotropic polypharmacy. The frequency was higher in BPD and psychosis.

Published: March 2024

Species belonging to the family Enterobacteriaceae cause infections that result in clinically significant morbidity and mortality. These organisms have been shown to harbor multiple mechanisms of resistance to antibiotics, including carbapenems. Molecular characterization of resistance to carbapenems is critical since few effective therapeutic options exist, most of which are difficult to access in resource-limited settings. One hundred twenty-six Enterobacteriaceae isolates with phenotypic resistance to at least one carbapenem were collected from two tertiary hospitals in the Philippines from 2014 to 2016. The organisms were screened for the presence of genes coding for carbapenemases and extended spectrum β-lactamases (ESBLs) using multiplex PCR. Multilocus sequence typing (MLST) was performed for Klebsiella pneumoniae, Escherichia coli and Enterobacter cloacae complex. The majority of the carbapenem-resistant isolates were K. pneumoniae (70/126, 55.5%) followed by K. ozaenae (19/126, 15%). Amplification of genes conferring carbapenem resistance showed blaNDM in 89 isolates (70%), followed by blaKPC in 21 isolates (16%). MLST revealed the presence of different clones including ST16 (5/70), ST17 (3/70) and ST147 (9/70) in K. pneumoniae, and ST10 (3/13) in E. coli. This study shows that blaNDM is the most prevalent carbapenemase type among carbapenem-resistant Enterobacteriaceae (CRE). Presence of carbapenemase gene and multiple ESBLs in the same organism pose a risk in the clinical setting since it could confer higher antibiotic resistance. This high rate of resistance poses the risk of spread since it can be transferred by mobile genetic elements. This study illustrates the acute need for effective therapeutic and hospital infection controls against CREs.

Published: April 2024

In this study, the influence of a U-tube passive anti-roll tank on parametric roll motion has been investigated as a mechanical absorber of a dynamic system. Specifically, this paper concentrates on how the initial conditions of a coupled roll motion and fluid motion in the tank act on the performance of an anti-roll tank. Parametrically excited roll motion was modeled as a single degree of freedom system incorporating heave and pitch effects by means of a time-varying restoring moment. Fluid motion in the tank was modeled as a single degree of freedom system. Coupled equations of motion were solved numerically and the results were presented in the time domain. Furthermore, the results were comparatively depicted as maximum roll amplitudes vs. initial values for a ship with and without an anti-roll U-tube tank.

Published: March 2024

Over 19 million cases of breast cancer were reported among women in 2020, surpassing lung cancer to become the leading cause of cancer worldwide. Women in developing countries have higher mortality rates than women in developed countries. Breast self-examination (BSE) is a simple procedure carried out by women themselves to determine any changes in their breasts and if needed seek further medical attention. This scoping review aimed to assess the available evidence on the knowledge and practice of BSE among women in Nigeria. This scoping review was conducted by searching African Journals On-Line (AJOL), ProQuest, PubMed and Science Direct databases for eligible studies. The relevant data was then extracted and a summary of the findings reported. 36 eligible articles were identified, 15 studies met the inclusion criteria and were considered for data extraction. All the studies included were cross-sectional descriptive surveys. The average reported knowledge of BSE is 67%, with 40% of study respondents practicing BSE, but only 26% of study respondents practiced BSE monthly. There’s low practice of BSE among women in Nigeria. Further research and appropriate interventions are needed to improve early detection and treatment of breast cancer.

Does Reduced Dwelling Time Leads To Higher Tax Revenue? The Important Role Of Government Effectiveness In ASEAN-5
Authors: Pascal Emilio , Wijaya Suparna
Published: March 2024

This study aims to analyze the factors that affect tax revenue on international trade in ASEAN-5 countries. Data was obtained from The World Bank and analyzed using panel data regression. Variables used in this study are tax revenue on international trade, import growth, dwelling time, and government effectiveness. The results show that import growth, dwelling time, import growth that has been moderated by government effectiveness, and dwelling time that has been moderated by government effectiveness simultaneously affect tax revenue on international trade. Partially, import growth, dwelling time, and government effectiveness have a positive effect on tax revenue on international trade. However, when moderated by government effectiveness, import growth and dwelling time show a negative effect on tax revenue on international trade. The recommendation from this study is for the government to improve the quality of public services in the process of loading and unloading goods. Effective public services at ports and airports, balanced with efforts to reduce dwelling time, will increase tax revenue on international trade. The steps that the government can take are to simplify business processes at the port, for example, joint inspection between customs and quarantine authorities. In addition, the government needs to sterilize port and airport areas so that unauthorized parties do not hinder the flow of goods in and out. Public service improvements can also be made in other sectors because they have a significant impact on increasing tax revenue on international trades.
