The weed control practices included in the study were i) Pendimethalin 30 EC 1.0 kg a.i./ha – 3 days after sowing, ii) Imazethapyr 10 SL 100 g a.i./ha – 20 days after sowing, iii) Quizalofop-p-ethyl 5 EC 50 g a.i./ha – 20 days after sowing, iv) Chlorimuron ethyl 25 WP 6 g a.i./ha – 20 days after sowing, v) Hand weeding (20 & 40 DAS) and vi) un-weeded control. The experiment was designed as RCBD with four replications. Growth models – Richards, Logistic, Cubic polynomial and Quadratic polynomial simulated the course of dry matter production/plant by >97per cent under all weed management practices, indicating that weed competition did not alter the pattern of crop growth, but affected the total production substantially.","PeriodicalId":385906,"journal":{"name":"Indian Journal of Botany","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128089750","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}

India would find this to be an excellent alternative to conventional remediation methods as it is a sustainable and inexpensive process. The huge retention of industrial waste in soil resulted in soil pollution which is more hazardous due to the long-term persistence of contaminants. A major source of hazardous waste products in Bhopal city is the industrial region. Near residential areas, industries produce pollution that can be very harmful to human health. The objective of this research was to determine which heavy metal accumulators are capable of absorption and translocation of heavy metals. In the Govindpura sampling sites, Cr and Ni concentrations were higher, while Cd concentrations were lower. Phytoremediation was conducted by comparing the heavy metal accumulation of Datura inoxia, Calotropis procera, Ricinus commmunis, and Polygonum in vitro cultures.","PeriodicalId":385906,"journal":{"name":"Indian Journal of Botany","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128810743","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}
