Comparative study of weed flora diversity in organic vs. conventional farming systems

Abstract

This study investigates the differences in weed flora diversity between organic and conventional farming systems. Utilizing a comparative approach, the research was conducted on adjacent plots in a temperate agricultural zone over a two-year period. Data collection involved systematic sampling to identify and quantify weed species. Biodiversity indices such as species richness, evenness, and Shannon-Weiner diversity were calculated. The results indicated significantly higher weed diversity and richness in organic farms compared to conventional ones, likely due to the absence of synthetic herbicides in organic practices. These findings suggest that organic farming could contribute to sustaining weed diversity, which is crucial for ecological stability and agricultural resilience. This study underscores the potential environmental benefits of organic farming practices and provides insights that could inform sustainable agriculture policies.
