Abstract:
Weeds are benefiting from climate change and will continue to do so because they are more diverse and have more flexibility. Climate change will alter the weed population, and invasiveness threats could rise. Current management techniques' effectiveness could be impacted. For almost 60% of the world's population, rice (Oryza sativa L.) is a major food crop. There are a number of biotic and abiotic elements that have an impact on rice production. Weeds are the primary biotic factor in yield loss, and temperature, soil moisture, and Co₂ are the primary abiotic factors. The study recommends that research on weed species, focusing on those weeds that benefited at high temperatures, soil moisture stress situations, and high Co₂ concentrations, is necessary.
