How do weeds reduce vegetable crop yields?

In the context of vegetable farming, weeds reduce crop yields primarily by competing with vegetable plants for essential resources, specifically water, light, and nutrients.12

Beyond direct competition, weeds negatively impact vegetable production in several other ways:

• Disease and Pest Harboring: Weeds often serve as hosts for plant disease organisms and insect pests that can subsequently attack and damage crop plants.31
• Increased Costs: The presence of weeds necessitates additional labor and resources for weed control, which increases overall production costs.3

To mitigate these issues, farmers employ various management strategies, including mechanical cultivation, manual weeding, and the application of herbicides.31
