It contributes 34 percent to the Gross domestic production, employs nearly 55 percent of the total labour force and generates the bulk of market exchange. Poor performance of the agricultural sector in relation to the fast-growing population, intensification of agriculture is the critical aim of the study to find land suitability for major crops of Varathuru watershed using remote sensing and GIS techniques. The objective is to assess the land suitability for major crops based on soil characteristics of Varathuru watershed. The depth-wise soil characteristics at soil series level used to arrive at site-soil characteristics for assessing crop suitability.The site-soil properties of soil series from the study area were matched with soil site suitability criteria for groundnut, redgram, sugarcane and rice crops that are grown in Varathuru watershed area and maps were generated by using ArcGIS V 10.3. Fifteen (15) soil mapping units at phase level were identified and were mapped into ten (10) soil series. The soil series VRT3 was highly suitable for growing groundnut, VRT1, VRT4, VRT5 and VRT8 soil series were moderately suitable for growing groundnut crop. VRT1, VRT3, VRT4, VRT5, VRT6, VRT7 and VRT8 soil series were moderately suitable for growing of redgram and VRT2 and VRT9 series were marginally suitable for growing of redgram crop. VRT1, VRT3, VRT4, VRT5 and VRT8 soil series were moderately suitable and VRT2, VRT6 and VRT7 soil series were marginally suitable for sugarcane growing. Whereas the soils of study area were not suitable for growing of rice crop.","PeriodicalId":11458,"journal":{"name":"Ecology, Environment and Conservation","volume":"81 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77827597","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 carried out to understand the floristic composition of both seed bank and standing vegetation across a range of five diverse anthropo-ecosystems in an urban region in Indian dry tropics. A total of one hundred soil samples (each of size of 25cm×25cm from 0-5 cm and 5-10 cm depth) from five anthropic sites (vegetation of University campus, polluted Kali River bank, Brick kiln, Waste land and Road side) were analyzed for their taxonomic position, life form and bio-geographic origin of the seedling emergents in relation to the flora in standing vegetation. A total of 221 plant species (58% aliens, 34% of aliens of American origin, 75% weedy herbs) in standing vegetation spread over 54 families were recorded in standing vegetation of the study sites with more than 55% representation from eight dominant families led by Fabaceae, Poaceae and Asteraceae followed by Malvaceae, Amaranthaceae and Solanaceae. In contrast, a total of 81 seed bank flora (10 unidentified, 62% aliens, 43% of American origin, 87% herbs) distributed over 32 angiospermic families were recorded. While none of the seed bank vegetation at any site showed significant similarity with its standing vegetation indicating the minor role of seed bank flora in the regeneration of the standing plant communities above ground. However, a considerable similarity among seed banks and standing vegetation at other sites indicated a significant possible role of anthropogenic activities in the urban regions of Indian dry tropics, evinced by the largest proportion of grasses and herbs dominated by exotics, especially of American origin. These aliens through successful naturalization via seed banks may cause homogenization of floristic structure. In conclusion, the present study revealed a heavy scale of intrusion by the alien plants dominated by American elements into not only standing vegetation but also in seed banks across the anthropic sites in urban regions in Indian dry tropics which is likely to alter the standing vegetation floristic structure with a larger abundance of alien flora.","PeriodicalId":11458,"journal":{"name":"Ecology, Environment and Conservation","volume":"138 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82834309","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}

For the investigation of physicochemical factors such such as water and air temperature, pH, transparency, total hardness, dissolved oxygen, total alkalinity, and chemical oxygen demand, water samples from the dam were taken. The acquired findings were compared to WHOBIS (World Health Organization and Bureau of Indian Standard) values permitted limits for drinking water. A few parameters at various stations were found to be close to the allowable limits. With reference to the analysed criteria, the current study identified how rainfall affects the water quality of Upper Kodera Dam water. Samples of 10 water were taken from Upper Kodra Dam between May 2021 and November 2022. Total hardness, Alkalinity, chloride, pH, total dissolved solids, iron, dissolved oxygen, fluoride, nitrate, sulphate, chromium, iron, chromium, and MPN of coliforms are among the biological and physicochemical parameters that were examined. According to the report, the current water supply needs urgent remediation since the water quality is subpar.","PeriodicalId":11458,"journal":{"name":"Ecology, Environment and Conservation","volume":"58 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90760325","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}
