Assam is endowed with dynamic rivers and lakes which in turn facilitates a rich diversity of fish species. 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.

A field experiment was carried out to study the effect of plant growth regulators on growth and yield of sweet pepper (cv Indra) in Rayagada district of Southern Odisha during September-January of 2019-20 and 2020-21. The experiment was laid out in Randomized Block Design with three replications and seven treatments. From the present study it was revealed that the maximum plant height (43.3 cm) was obtained with IAA (100 ppm) whereas maximum fruiting branches (8.20), maximum fruit weight (106.80 g) was obtained with 2,4-D (10 ppm). Maximum polar diameter (6.6 cm), shoulder diameter (5.2 cm) and single fruit weight (82.3 g) was obtained with BA (5 ppm). Maximum fruit yield (13.8 t/ha) was recorded with BA (5 ppm). Early fruit fetches higher market price than late harvested fruit and gives higher return to farmer which was obtained by application of BA (5 ppm) i.e., 28.1 days for first flowering and 60.2 days for first harvesting.

The present study characterizes twenty-one rhizobacterial strains isolated from root nodules of Vigna trilobata cultivars collected from various Andhra Pradesh, India districts. 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.

Proper management of nitrogenous fertilizers is of paramount importance for economical crop production and sustainable soil-water-atmosphere ecosystem. 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.
合理施用氮肥对作物经济生产和土壤-水-大气生态系统的可持续发展至关重要。本试验研究了不同施氮水平对滴灌菜花作物生长的影响。采用滴灌系统，每次施用35等量氮肥(尿素)，隔日施用灌溉水。每隔两周记录不同处理土壤剖面的土壤水分。在所有土壤深度上，随径向距离的增加，观测到的含水率有减小的趋势。在所有径向距离上，在整个土壤剖面上，在所有处理中，土壤水分都随土壤深度的增加而减少。结果表明，施氮90 kg ha-1(75%推荐施氮量)、120 kg ha-1 (100% RDN)和150 kg ha-1 (125% RDN)的菜花产量分别为221、231和234 q ha-1。75% RDN、100% RDN和125% RDN条件下的水分利用效率分别为80.7 kg m-3、84.2 kg m-3和85.4 kg m-3。75% RDN、100% RDN和125% RDN条件下，氮素利用效率分别为245.6 kg kg-1、192.2 kg kg-1和156 kg kg-1。提高氮肥水平对花椰菜产量和水分利用效率没有显著提高，但在很大程度上降低了水分利用效率。

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}
Guava varieties for different morpho-physiological traits were evaluated at Guava Demonstration Center, Bhuna (Fatehabad) and in Postgraduate Laboratory of the Department of Horticulture, CCS Haryana Agricultural University, Hisar during the year 2018-19 for both the season i.e., rainy and winter. Quantitative and qualitative characters of fifteen guava varieties with distinct variation was observed. Among these characters flowering and fruit were critical observed and a wide variation in flowering parameters has been recorded. The time of flower initiation period varied from 20th April to 1st May. The duration of flowering of different guava varieties during rainy season showed variations from 27 to 35 days. Pant Parbhat, Banarsi Surkha showed ovate shape of fruit, while, Barf Khana had globose type of fruit shape. KG Guava had maximum fruit length of 10.05 cm and diameter (width) of 8.16 cm during rainy season. Highest fruit weight of 362.0 g and 412.3 g was noticed in KG Guava during both the season i.e., rainy and winter.
