- W3158351341 abstract "Weeds present a major challenge to crop production and need tobe controlled. Several methods of weed control exist but theyhave proved to be less than successful especially in the tropics;therefore new ways of using these methods are still beingsought. The use of allelopathy, a form of biological weedcontrol, has been proposed. A systematic screening of 6sunflower varieties, a crop known to have allelopathic activitieswas done at the Field Station of the University of Zambia in the2008/09 and 2009/10 rain-fed growing seasons using a RCBDwith 2 maize varieties as the control. Weed diversity wasobserved, while weed density, weed biomass and crop yieldwere measured and subjected to analysis of variance. Resultsshowed that although there was a wide diversity of weedspresent, 15 were most prevalent. Sunflower varieties,generally, had lower weed density and weed biomass than thecontrol maize varieties. But varietal differences among thesunflower varieties were discerned. The yield reduction washigher in maize grown in a weedy environment than for thesunflowers although here again varietal differences wereevident among the sunflowers. It was concluded that the use ofsunflower varieties Milika, Record and PAN7352 as analternative crop can help to reduce weeds in the field." @default.
