The western Assam geographically blessed with such a river named Tipkai. Tipkai River is a Himalayan tributary of the Brahmaputra River in the Indian state of Assam which raises in the Bhutan hills flows through the Kokrajhar (BTR) and through Dhubri district of Assam and joins the Brahmaputra River at Chatakurachar of Dhubri district. The present study deals with the extensive Ichthyological fields survey conducted over a period of oneyear from January 2021 to December 2022 based on the data collected from six locations of the river from the Mahamaya (Bagribari) to Chatakurachar. The survey revealed the occurrence of great range of diversity of fishes representing 106 species distributed under 10 orders and 31 families. Among the recorded fish species 4 species are Vulnerable (VU), 2 species are Near Threatened (NT), 3 species are Endangered (EN),86 species are least concern (LC) while 3 species are Not Evaluated (NE), 2 species are Data Deficient (DD) with 65 genus, 10 order and 30 families. The highest order Cypriniformes with 49 species, Siluriformes 27 species Perciformes 17 species. The site Khoraghat represents the lowest fish diversity among the six sites during the study period might be due to sand mining and other anthropogenic reasons which needs further analysis of water quality. Thus, this beautiful river, a small tributary from Bhutan serves the land cover and maintains its beautiful biodiversity and also the lifeline for mankind.","PeriodicalId":36141,"journal":{"name":"Environment and Ecology Research","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136246720","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}

Rhizobacteria was isolated using selective medium Yeast Extract Mannitol Agar medium (Y.E.M.A.). All 21 strains were characterized based on colony morphology and biochemical characterization and identified up to species level by 16S rDNA sequencing analysis. Different genera of the bacteria are present in the root nodules of Vigna trilobata. Short random sequence primers amplify genomic D.N.A. in a process called random amplified polymorphic D.N.A. (R.A.P.D.), which were employed to assess genetic variation across isolated bacterial strains. Banding patterns were obtained via R.A.P.D. analysis of genomic D.N.A. from the isolates using five random primers, including OPA-4, OPA-9, OPA-11, OPA-12, and OPA-15. The R.A.P.D. profiles of twenty-one rhizobacterial isolates were compared separately to determine their differences by the occurrence of polymorphic D.N.A. fragments. PCR amplified of the D.N.A. isolated from twenty-one bacterial isolates yielded seventy amplified products, of which sixty-eight were polymorphic, and two were monomorphic. The investigation found that R.A.P.D. could differentiate between the strains very precisely. Characterizing and creating novel Rhizobium species can be aided by using molecular markers to investigate genetic diversity.","PeriodicalId":36141,"journal":{"name":"Environment and Ecology Research","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135640509","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 present study was conducted to examine the effect of different nitrogen fertigation levels on cauliflower crop through drip irrigation. The nitrogen fertilizer (urea) was applied in 35 equal doses with irrigation water applied at alternate day through drip irrigation system. Soil moisture in the soil profile of different treatments was recorded at fortnight interval. The observed moisture content tended to decrease with increase in radial distance from the drip lateral at all soil depths. The soil moisture tended to decrease with increase in soil depth at all radial distances, throughout the soil profile, during whole crop period, in all the treatments. The cauliflower yield with N-fertigation of 90 kg ha-1 (75% of Recommended dose of N), 120 kg ha-1 (100% RDN) and 150 kg ha-1 (125% RDN) was found to be 221 q ha-1, 231 q ha-1 and 234 q ha-1 respectively. The water use efficiency (WUE) was calculated to be 80.7 kg m-3, 84.2 kg m-3 and 85.4 kg m-3 under 75% RDN, 100% RDN and 125 % RDN respectively. The nitrogen use efficiency (NUE) was found to be 245.6 kg kg-1, 192.2 kg kg-1 and 156 kg kg-1 under 75% RDN, 100% RDN and 125% RDN respectively. The increased N-fertigation level did not improve the cauliflower yield and WUE much but reduced the NUE to a great extent.","PeriodicalId":36141,"journal":{"name":"Environment and Ecology Research","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135735482","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 experiment was conducted in seed testing laboratory, Department of Seed Science and Technology, Bidhan Chandra Krishi Viswavidyalaya, Mohanpur, Nadia, West Bengal, India during 2020-2021 following Complete Randomized Block Design with three replications in order to standardize the appropriate concentration and duration while soaking the seeds within PEG-6000 solution for screening a range of duration concentrations viz, 10 g liter-1 for 6 hrs, 10 g liter-1 for 8 hrs, 10 g liter-1 for 10 hrs, 15 g liter-1 for 6 hrs , 15 g liter-1 for 8 hrs, 15 g liter-1 for 10 hrs, 20 g liter-1 for 6 hrs, 20 g liter-1 for 8 hrs, 20 g liter-1 for 10 hrs, 25 g liter-1 for 6 hrs, 25 g liter-1 for 8 hrs, 25 g liter-1 for 10 hrs. Untreated dry seeds were considered as control. It was found that all the priming treatments showed significance difference in overall including the control. The best performer or the better result was shown by T8 which is 20 gm/ liter solution with the soaking duration of 8 hrs. It was highest performer in germination percentage (93.77), root length (6.57 cm), shoot length (16.57 cm), seedling fresh weight (1.66 g), seedling dry weight (0.14 g), seedling vigour index I (2137.07), time to 50% germination (2.33 days) and germination index (77.82). This study showed that seed priming with osmotic solution could improve some seedling parameters in chickpea. In seed priming, its simplicity such as no requirements for extensive equipment and chemicals could be used method for overcoming problems related to a poor germination and further seedling establishment and helps in sustaining agriculture with a cost effective approach and with the help of seed priming treatments which are non-toxic and from eco-friendly sources.","PeriodicalId":36141,"journal":{"name":"Environment and Ecology Research","volume":"386 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135640517","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}
