Journal Title: Indian Journal of Biology - Year 2018, Vol 5, Issue 2
Abstract
A survey was conducted at fifty different rice fields in coastal areas of Lucknow region to identify most common and prevalent weeds associated with rice. Fields surveyed were done according to the quantitative survey method by using 0.5m× 0.5m size quadrate with twenty samples from each field. Total thirty weed species were collected which related to fifteen families and twenty six generas from the rice field in the Lucknow region. The weed survey of this region was made during August to November 2013. Maximum number of species (eight) belongs to family Euphorbiaceae, followed by Family Asteraceae (three species), Amaranthaceae and Cyperaceae (three each species). Three species were found to be Poaceae, two Solanaceae and Molluginaceae. One species were found to be remaining families. In floristic survey, two weeds were found to be climber, six were prostrate and remaiing was erect. Thirteen weeds were found to be common, eleven were occasional and six were rare in kharif season rice fields.
