Phytosociological attributes of weeds in lowland paddy at Talata Mafara, Sudan Savannah, Nigeria
Abstract
Study was conducted to assess the phytosociological studies of weed species in paddy at research farm of the irrigation research station, Institute for Agricultural Research (I.A.R), Ahmadu Bello University, Zaria located at Bakolori irrigation scheme Talata Mafara, (Zamfara) State, in the Sudan Savannah ecological zone of Nigeria during 2012 and 2013 wet seasons, A total of 19 and 26 weed species were identified during the 2012 and 2013 wet seasons respectively. The results obtained indicated that Echinochloa colona, Cyperus difformis, Digitaria horizontallis, were the most densely populated in 2012 while Digitaria horizontallis, Echinochloa colona and Cyperus iria were the most densely populated weeds in 2013. The most important weeds in the 2012 were E. colona followed by D. horizontallis and C. difformis while in 2013 the importance value index (IVI) revealed that the most important weeds within the community were D. horizontallis, E. colona and C. iria. The most important weeds that were associated with the rice crop in the study area are of grass and sedge family.
