- Abstract
Murdannia nudiflora, also known as trapoerabinha has been reported in recent years, as an important weed in soybean crops under no-tillage in Brasil, due to its highly competitive with crops, poor control and rapid infestation. The present work was to study germination of seeds under light conditions (and without) and temperature (20, 25 and 30 ℃), and the emergence in straw (with and without) and sowing depth (0, 0, 1.0, 2.0, 3.0, 4.0 and 8.0 cm). The experimental design was completely randomized for all experiments. The species studied presents photoblastism preferred, with higher germination under light. Depths greater than 1.0 cm and the presence of mulch on the soil surface affect the emergence of seedlings of this species.
