Effect of weedy rice variants and weedy rice density on the growth and yield of two rice cultivars in the Philippines

Answer the question truthfully.  <|eot_id|><|start_header_id|>user<|end_header_id|> Here is the Description of a dataset. Description:'Weedy rice (Oryza sativa L.) is an emerging problem in direct-seeded rice (O. sativa L.) systems in the Philippines. Limited information is available on the effect of weedy rice variants and density on the growth and yield of cultivated rice. A study was conducted to determine the effect of two weedy rice variants (WR1 and WR2) grown at different densities on the growth and yield of two rice cultivars (Mestiso21, a hybrid, and Rc222, an inbred). Rice data (plant height, leaf number, tiller number, aboveground shoot biomass, panicle number, and grain yield) were obtained at crop maturity. Shoot biomass of rice cultivars was similar when grown without weedy rice. In competition with weedy rice, however, both rice cultivars produced higher shoot biomass when grown in competition with WR1 than with WR2. The grain yield of rice was similar b' .
