A field experiment conducted during the winter season of 2012-13 at Tirhut College of Agriculture Farm of RAU, Pusa (Samastipur) to examine the effect of manual, herbicidal and integrated treatments on the weed dynamics, yield and economics of lentil. The experiment was constituted integrated weed management methods as well as chemical and conventional. Weed control treatments significantly influenced various growth parameters, yield attributes and yield of lentil. Hand weeding recorded maximum growth and yield which was significantly superior over remaining treatments. The prominent weeds were Anagallis arvensis, Cannabis sativa, Cyperus rotundus, Cynodon dactylon, Chenopodium album and Parthenium hysterophorus, and these weeds together constituted 63.4 per cent of the total weed population in research field. All the weed control treatments reduced the weed population and dry matter of weeds significantly over weedy check. The pre-emergence herbicides were proved more effective than post-emergence and pre-plant incorporated herbicides. Returns were significantly higher under hand weeding, however, the B:C ratio was highest under pendimethalin + imazethapyr 1.00 kg/ha as PE.
Handbook of Cannabis and Related Pathologies: Biology, Pharmacology, Diagnosis, and Treatment is the first book to take an interdisciplinary approach to the understanding of cannabis use and misuse. Recent worldwide trends toward decriminalizing marijuana for medical use have increased legal use of the drug and recreational use remains high, making cannabis one of the most commonly used drugs.Cannabis has a wide range of adverse neurological effects, and use and abuse can lead to physical, social, and psychopathological issues that are multifarious and complex. Effective understanding and treatment requires knowledge of the drug's effects from across scientific disciplines.This book provides an overview of the biological and pharmacological components of the cannabis plant, outlines its neurological, social, and psychopathological effects, assists in the diagnosis and screening for use and dependency, and aids researchers in developing effective treatments for cannabis-related issues and disorders.Fully illustrated, with contributions from internationally recognized experts, it is the go-to resource for neuroscientists, pharmacologists, pathologists, public-health workers, and any other researcher who needs an in-depth and cross-disciplinary understanding of cannabis and its effects.Comprehensive chapters include an abstract, key facts, mini dictionary of terms, and summary pointsPresents illustrations with at least six figures, tables, and diagrams per chapterProvides a one-stop-shopping synopsis of everything to do with cannabis and its related pathology, from chemicals and cells, individuals and communities, and diagnosis and treatmentOffers an integrated and informed synopsis of the complex issues surrounding cannabis as a substance, its use, and its misuse
