Understanding the dimensions of guinea grass for its invasiveness, adaptability and persistence

Guinea grass (Panicum maximum) an important forage and pasture crop poses a threat to biodiversity and conservation as it is found to invade and persist in different soil, land types, agroclimatic conditions, soil moisture availability, etc. Though this crop is economically important in the livestock sector, the extreme tolerance for stress, competitive ability, resistance to chemicals, ratooning ability, robustness, morphological adaptation, ecotypes, reproductive nature, etc has led this crop as a pantropical crop. Due to its strong invasiveness and persistence, the economic and ecological impact it causes in the agricultural sector is serious. As the invasiveness and persistence of the guinea grass population have been observed throughout the year at the livestock farm complex, TANUVAS, this paper has been reviewed to understand the strategies that guinea grass possesses for its invasion, adaptation, and persistence.
