Abstract
Weedy rice is a complete group of species that belongs to the genus Oryza, and which behaves as a weed. It is an annual grass that is relatively similar with cultivated rice. The life cycle, morphological characteristics and yield components of weedy rice from Dingle, Iloilo were studied. Likewise, the effects of light and different salt concentrations on its germination were investigated. Results showed that weedy rice, compared with cultivated rice, persisted to grow taller, and to produce less leaves and tillers. It exhibited moderate grain shattering, had varying awn characteristics, and had a shorter life cycle by 35 days. The mean number of panicles per plant, percent filled grains and 100 grain weight of weedy rice were lower than cultivated rice. Germination of weedy rice was not significantly affected by light but significantly influenced by salt concentrations.
