The investigation was conducted during the rabi season (September 2019 to February 2020) of 2019 to 2020 at the research field of All India Co-ordinated Vegetable Crops, located at Bidhan Chandra Krishi Viswavidyalaya in Kalyani, Nadia, West Bengal, India. The aim of the study was to examine the characteristics of twenty-six chilli genotypes across twelve qualitative traits. The investigation unveiled a broad range of phenotypic variability using Randomized Block Design in three replications. Among the assessed traits, leaf density, leaf shape, fruit shape, plant habit, fruit curvature, and anther colour exhibited the most extensive variations among the genotypes. Conversely, the traits with the least diversity values, all falling below the overall mean, included fruit surface (0.28%), leaf colour (0.42%), stem pubescence (0.42%), stem colour (0.42%), anthocyanin colouration at nodes (0.48%), and leaf pubescence (0.48%). The Shannon-Weiner Diversity Index (H') ranged from 0.28 to 1.07. Of the traits evaluated, leaf density displayed the highest diversity index (1.07), followed by leaf shape (1.05), fruit shape (1.01), plant habit (0.86), fruit curvature (0.69), and anther colour (0.58). The obtained Shannon-Weiner Diversity Index, with an average value of 64.66%, confirmed the presence of significant diversity within the examined chilli genotypes. The results suggest that the indirect selection of chilli parent plants based on a range of morphological characteristics can offer advantages in the management of both biotic and abiotic stresses. The information holds significant value for effective pre-breeding, management, and utilization in crop improvement initiatives, in addition to augmenting the genetic potential of the crop.

The present study was conducted during August 2021 at Buffalo Research Station, Venkatarammanagudem of West Godavari District, Andhra Pradesh, India and was aimed to detect the presence of extended-spectrum beta-lactamases (ESBL) producing P. aeruginosa from sub-clinical mastitis that are apparently healthy Murrah buffaloes. Inflammation of the udder by microbial infection is one of the leading economic disease in the dairy sector. Most of the pathogens especially Pseudomonas aeruginosa are refractory to the antibiotic theraphy. Nowadays, the antimicrobial resistance owed by the bacteria is at an alarming rate. Pseudomonas aeruginosa, a multi drug resistant pathogen carry the extended spectrum beta lactamase genes in its plasmids and thus become resistant to antibiotic therapy. A total of 276 milk samples were collected from 69 milch animals in the month of August, 2021 comprising from all the four quarters of each buffalo. Nine (n=9) (3.26%) P. aeruginosa isolates were identified from the sub-clinical mastitis milk samples from the total 276 samples collected in the study. The isolates on morphological analysis were typical to P. aeruginosa. Seven isolates were positive for phenotypical beta-lactamases production. A total of 1 and 2 isolates were found reactive of the blaSHV and blaOXA genes, and two isolates harboured both blaSHV and blaOXA genes, respectively on PCR assay. No blaTEM gene was found in the isolates. Antibiogram of the ESBL producing P. aeruginosa isolates (n=7) possessed 100% resistance against most of the commonly used antimicrobials like ampicillin, amoxycillin, clindamycin, co-trimoxazole oxytetracycline, streptomycin and ceftriaxone (85%). The P. aeruginosa isolates were sensitive to amikacin (100%), ciprofloxacin (87.4%), gentamicin (84%), norfloxacin (84.8%) and enrofloxacin (82%).

The present study was undertaken during October, 2020–January, 2021 at Maize Research Centre, Professor Jayashankar Telangana State Agricultural University, Rajendranagar, Hyderabad, Telangana state, India to identify potential inbred lines and hybrids with early maturity and high yield through combining ability analysis and heterosis. Six lines and four testers were crossed in L×T design to obtain 24 crosses. Evaluation of these crosses and their parents for combining ability revealed significant differences due to lines, testers and their crosses indicating the existence of wider variability among the material used in the study. Maize line MGC 434 (91 days), two testers GP-170 and PFSR-56 (91 days), and one hybrid MGC-445×PFSR-132 (83 days) were identified as early duration genotypes. Four lines MGC-444 (-3.13), MGC-440 (-2.71), MGC-439 (-1.96) and MGC-445 (-0.46) with significant negative GCA effects were identified as best general combiners for early maturity. Eight hybrids, MGC-439×BML-14 (-4.99), MGC-445×PFSR-56 (-4.65), MGC-461×PFSR-56 (-3.65), MGC-445×PFSR-132 (-3.60), MGC-434×BML-14 (-2.32), MGC-439×GP-170 (-2.10), MGC-440×PFSR-56 (-2.07) and MGC-440×GP-170 (-1.01) with significant negative SCA effects were considered as best cross combinations with early maturity. The inbred parents and cross combinations with early maturity identified in the study can be utilized for development of hybrids suitable to drought prone environments.

The present study was conducted during the late kharif season (July to November, 2023) at the Genetics and Plant Breeding Research Farm, School of Agriculture, Lovely Professional University, Phagwara, Punjab India. This study assessed heterosis in okra (Abelmoschus esculentus L.) for 12 traits, including earliness and fruit yield using Randomized Block Design. Thirty-five F1s were obtained from crossing 7 lines with 5 testers in line×tester method and compared with one commercial check (Punjab-8) to estimate standard heterosis and heterobeltiosis among better parents. Significance of mean square due to genotypes revealed the presence of considerable genetic variability among the material studies for almost all the traits. The best positive heterotic cross over better parent (Heterobeltiosis) and standard check (Punjab 8) for fruit yield plant-1 was Go-6×Arka Abhay (72.32%) and Phule Prajatiti×Arka Abhay (41.63%) respectively. While Punjab Suhanani×GAO-5 (-12.05%) was found as negatively heterotic cross for days to 50% flowering over better parent and GAO-8×Arka Abhay (-13.26%) over standard check respectively. For days to first picking Pusa Savani×VRO-106 (-14.44%) exhibited negatively significant heterosis over better parent and Phule Prajatiti×Arka Abhay (-14.49%) over standard check respectively, that are important to exploit the earliness traits in okra. The hybrid Phule Prajatiti×Arka Abhay, which has a high potential for yield and fruits can be picked earlier which may evaluated further for early kharif season in Punjab.

The current research was conducted during May–October, 2023 aimed to assess the haemato-biochemical parameters in cattle affected with S. aureus affected subclinical mastitis. Mastitis in dairy cattle is the persistent, inflammatory reaction of the udder tissue. Financial losses due to mastitis occur in the case of both sub-clinically and clinically affected animals. Sub-clinical mastitis exhibits no clinical signs and mostly remains unnoticed by the farmer and can be detected if specific tests are performed in milk samples. Sub-clinical mastitis has an erosive effect on the economy of dairy farmers as it effect directly on the milk quality and quantity. In India prevalence of sub-clinical mastitis was found to be more in cows when compared to clinical mastitis. Blood samples were collected from the jugular vein of 10 healthy and 10 subclinical mastitis affected cattle. Blood samples were analyzed for Hb, PCV, TEC, TLC, while serum samples were examined for ALT, AST, ALP, Glucose, Total protein, Albumin, Cholesterol and Calcium. Haematology report showed significantly (p<0.01) decrease in Hb, PCV and TEC in subclinical affected cattle when compared to healthy animals. TLC was significantly increased in (p<0.01) subclinical affected animal than healthy animal. Biochemical estimate revealed significantly (p<0.05) higher average values of AST, ALP and Ca in subclinical mastitis affected animals compared to healthy animals. Glucose, total protein, albumin, cholesterol and ALT levels are significantly (p<0.05) decrease in subclinical mastitis affected animals when compared to healthy cows. Haemato-biochemical parameters can be used as important for pathological state of subclinical mastitis animals.

The present study was carried out during November–April, 2019–2020 and 2020–21 with eight diverse barley genotypes and their developed 28F1s (half diallel, excluding reciprocals) to ascertain gene effects, hetrosis and correlations for grain yield, yield attributes and physiological traits under water limited conditions of Bundelkhand region. Days to heading and days to maturity exhibited general mean values of 86 days and 127 days, respectively. The parental genotypes, DWRB180, RD2794 and RD2899 showed early spike emergence and maturity. The cross combinations, namely DWRB160 /DWRB180, DWRB180/RD2907 and BH946/RD2552 were promising for flag leaf length and width. The GCA effects were significant and prevalent for all the characters, except days to heading, plant height and tillers count. The parents, DWRB160 (5.29**) and BH902 (1.59**) depicted high GCA effects for 1000 grain weight. The parents, DWRB180, RD2552, and BH946 exhibited significant positive GCA effects for leaf area index and chlorophyll fluorescence, whereas the genotypes, RD2907, BH946 and RD2899 showed higher GCA effects for chlorophyll content. Grain yield exhibited significant positive correlations with flag leaf width (0.60**), tillers per meter (0.35*), grains per spike (0.39*), harvest index (0.53**), chlorophyll content (0.69**), leaf area index (0.49**) and chlorophyll fluorescence (0.68**). The parents, BH946, DWRB180 and RD2907 and the hybrids, RD2552/DWRB180, BH902/RD2794, DWRB160/DWRB180 and BH946/RD2907 were found promising for yield and yield attributes in the dry agro-ecology of Bundelkhand region. The crosses, DWRB160/BH902 and DWRB160/BH946 can be explored for developing superior segregants for malt barley breeding.

The present investigation was conducted during June, 2021 to February, 2022 in twelve villages under DAATTC, six each in Bhuvanagiri and Jangaon districts, Telangana, India on the use of social media as a source of agricultural information, use pattern, preference, purpose, ranking of different social media used, information processing and its effectiveness among farmers. Social media emerged as highly powerful tools in facilitating online social interactions and has shown tremendous potential in facilitating information exchange among individuals. These tools are meant for digital communication helping in interaction among a group of people. The data were collected from farmers of Bhuvanagiri and Jangaon districts, with a sample size of 120 respondents through a structured interview schedule. 84.16% of the farmers used social media platforms for getting agriculture related information, the most preferred social media were WhatsApp, Youtube and Facebook. Garrett ranking analysis revealed that information seeking was the most preferred purpose of social media use among farmers followed by chatting/connecting with peers and watching agricultural videos. 54.17% of the farmers preserved this information obtained from social media for future use. 45.00% of them discussed this information with progressive farmers and 42.50% of them discussed with friends. 72.50% of the respondents had enhanced knowledge about pest and diseases. The personal variable of the respondents’ such as education, farm-size, scientific orientation, social participation, income, innovativeness and information seeking behaviour were significant and positively correlated (at 0.01% level of probability) with social media use.

The personal variable of the respondents’ such as education, farm-size, scientific orientation, social participation, income, innovativeness and information seeking behaviour were significant and positively correlated (at 0.01% level of probability) with social media use.","PeriodicalId":423570,"journal":{"name":"International Journal of Bio-resource and Stress Management","volume":"94 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140495605","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
The research was conducted at Kulumsa Agricultural Research Center Main Station, during July–November, 2021 (Main cropping season) to study the association among traits and estimate the direct and indirect effects of various traits on grain yield of bread wheat genotypes. A total of 64 bread wheat genotypes were evaluated for 16 traits in 8×8 simple lattice design. Grain yields showed positive and highly significant at (p<0.01) genotypic and phenotypic correlation with plant height, number of seeds spike-1, head weight, yield head-1, biomass yield, hectoliter weight, test weight and harvest index. Genotypic correlation coefficients were greater for all significantly correlated with grain yield studied traits than the corresponding phenotypic correlation coefficients, indicating inherent association of the characters, therefore, selection for these characters could improve grain yield. Genotypic path analysis of the direct effects revealed that days to maturity, number of spikelets spike-1, head weight, yield head-1, biomass yield, hectoliter weight, test weight and harvest index exerted direct positive effect on grain yield. Phenotypic path analysis of the direct effects showed that days to maturity, plant height, number of tillers plant-1, number of seeds spike-1, head height, yield head-1, biomass yield, test weight and harvest index had direct positive effect on grain yield. Therefore, these traits should be considered for bread wheat breeding program for yield improvement.

Eucalypt is an industrial short rotation fast growing tree species (SRFGTs), having wide range regarding climatic and edaphic requirements in Indian subcontinent. Eucalyptus camaeldulensis, E. globulus, E. grandis, E. tereticornis and E. citriodora are the widely planted eucalyptus species for different purposes in the country. Oil extracted from E. globulus has medicinal value and used to inhibit the avian influenza virus H11N9, and has wide scope in cosmetics, perfume, food, beverages, phytotherapy and aromatherapy. Oil contain p-coumaric, gallic, gentisic, p-hydroxybenzoic, syringic and vanillic acids and catechol are the responsible for retarding seed germination growth and survival of Parthenium, Solanum lycopersicum, Lactuca sativa and Agrostis stolonifera. Burning of eucalypt leaves used as mosquito repellent and compound 1, 8 cineole of eucalypt oil damage and kills Pediculus humanus capitis and lice. Aqueous solutions extracted from different parts of eucalypt showed nematocidal properties. Maize, wheat, mustard, berseem, potato, lentil are agricultural crops widely grown under eucalypt based agroforestry systems. Wider spacing of eucalypt in block plantations or boundary plantation mostly adopted in the agroforestry systems. Eucalypt sequester carbon 6 – 43 Mg C ha-1 yr-1 under plantations and agroforestry systems. The species has potential to reclaim waterlogged sites and escalate soil health through improving soil physical, chemical and biological properties. In case of economic returns from eucalypt based agroforestry systems, it gives nearly 1.5 B:C ratio.

The study was conducted during April, 2021 to June, 2022 to study the isolation and identification of high effective strains of phosphate solubilizing bacteria and evaluation the ability to solubilize tricalcium phosphate in vitro. Microorganisms that live in soil are actively involved in the carbon, nitrogen, sulphur, and phosphorus cycles in nature, enabling them to maintain ecological balance. Phosphate-solubilizing microbes are used as agricultural biofertilizers and play an essential role in plant nutrition by enhancing phosphate uptake. Phosphate is one of the most important macronutrients necessary for the growth and development of plants. Numerous microorganisms present in the rhizosphere solubilize insoluble phosphorus, making it readily available to plants. Fourteen phosphate-solubilizing bacterial colonies were identified on Pikovskaya’s agar medium, containing insoluble tricalcium phosphate (TCP) from rhizospheric soil. Among them, eight colonies showing clear halo zones around the microbial growth were considered as phosphate-solubilizing. All isolates showing the highest phosphate solubilization index (PSI), ranging from 2.8 to 4.03, were selected for further qualitative and quantitative studies. Out of these eight potent isolates, two strains showed the maximum PSI: V7 (4.03) and V8 (3.85) in agar plates, along with a high production of soluble phosphate, measuring 448.03 and 441.43 mg l-1, and a greater reduction in pH in the broth culture. The morphological, biochemical, and molecular identification of V7 and V8 strains revealed them to belong the Acinetobacter and Paenibacillus genera, respectively, and were phylogenetically close to Acinetobacter baumannii and Paenibacillus lautus species.
