This work aimed to study the phenology and accumulation of dry matter of Murdannia nudiflora along its life cycle to determine its growth potential. Seeds were sown in 5.0 x 3.0 x 0.2 m in substrates from lowland soil from irrigated - rice cultivated areas. Treatments consisted of 11 different plant harvesting times (10, 20, 30, 40, 50, 60, 70, 80, 90, 100 and110 days after emergence) with 6 plants being harvested per time and divided into the following components: Pseudostem, roots and leaves followed by dry matter determination. Pseudo stem development increased linearly throughout the cycle. The highest total dry matter accumulation in the roots and leaves occurred between 20 and 80 DAE, presenting quadratic adjustment. After 80 DAE, 59%, 31.7% and 9.3% dry matter accumulation was observed in the stolons, leaves and roots, respectively, compared to the parent-plant. Daughter-plant formation was found to occur after 40 DAE, with dry matter production reaching an average of 84.8% of the total plant dry matter, after peak production (80 DAE). Dry matter accumulation in the parent-plant was similar to that in the daughter-plants, with the latter's tending to remain constant after peak production.
