Abstract
In Uganda as in other parts of Africa, the state of weeds in particular farming system is determined by the number of weeds present in the soil. Weeds act as secondary host for harmful insects and illnesses and hinder harvesting operations; by studying the weed flora present in cassava gardens farmers can identify the most problematic weed species and develop effective strategies to control them Information on weeds of cassava in Nagongera is limited. The objective of this study was to establish the status of weed flora in selected cassava growing gardens and determine the population of both broad-leaved weed species and grass weed species. This study was conducted in April 2024 in Nagongera gardens in the faculty of science and Education, Nagongera sub county Tororo district Eastern Uganda. Weed densities were estimated from twelve quadrant samples taken systematically along diagonal transects, in 5 fields. Grass weed species were the most frequent averaging 55.01% of the entire weed species. four weed species predominated i.e. Camelina benghalensis, black jack, spear grass and couch grass. Data showing the relative frequencies of weeds was be analyzed using GenStat 14 Edition statistical package. Significant means were separated using least significant difference (Fisher’s LSD) at 5% probability level. This should form the basis for selection of feasible and safest options for control of cassava weeds. Different management weed practices should be applied in order to control different weeds existing in cassava fields. Weed management is often accomplished by mechanical techniques, such as pulling, submerging, or other similar methods. Uprooting should be done before the seeds of this plant begins to spread, and additional methods of management should include herbicide spraying.
