Purslane weeds growth control can be conducted preventively since germination stage. This study aims to determine the duration and immersion depth of purslane weeds to find information about the seeds’ viability at different germination temperatures. The research observed two factors, namely the durations of immersion at 2, 4, 6, And 8 weeks, and the depths of immersion at 0, 5, 10, and 15 cm. The experiment method and germination test used randomized factorial design with three repetitions and were continued with least significance difference (LSD) test. The results of the research showed that the interaction between the duration and the immersion depth of purslane weeds significantly affected the germination percentage, germination rates, and germination synchronization at the temperatures of 30C and 40C. The longer and the deeper the seeds immersed, the lower the viability of the purslane weeds seeds was. The growth control of purslane weeds can be conducted by reducing the seeds germination.
