Amaranthus viridis, a weed found in upland rice farming poses a threat, to crop plants because it competes for vital resources like water, minerals, and nutrients. This competition leads to decreases in crop yield. To tackle this issue a designed study was conducted to examine the characteristics of Amaranthus viridis in three different locations with distinct environments. The results showed a meaningful connection between traits such as dry weight, fresh weight, plant height, leaf area, leaf width, leaf length and root length. Interestingly the width of the plant leaves was found impact on its height. Additionally, location two was identified as an environment for the vigorous growth and development of Amaranthus viridis plants. To effectively minimize losses, in crop yield caused by this weed it is strongly recommended to remove or control Amaranthus viridis populations. This study underscores the importance of population management strategies.
