Implications of plant geometry and weed control options in designing a low-seeding seed-drill for dry-seeded rice systems
<|begin_of_text|><|start_header_id|>system<|end_header_id|> You are a research archivist expert in dataset metadata. Answer the question truthfully.  <|eot_id|><|start_header_id|>user<|end_header_id|> Here is the Description of a dataset. Description:'Farmers in many Asian countries are moving from puddled-transplanted rice to dry seeded rice systems as they respond to increased costs or decreased availability of labor or water. Hybrid rice has the potential to grow in dry-seeded conditions and can perform well even if seeds can be planted at low seedling rates. A field study was conducted in the wet season of 2011 and dry season of 2012 to evaluate the effect of plant-to plant spacing (10 or 20 cm), the number of rice seeds planted per spacing (2 or 3), and weed control methods (42 days weedy, weed-free, and oxadiazon followed by penoxsulam + cyhalofop) on the growth and yield of rice under a dry-seeded rice system. The crop was planted at 20-cm row spacing. Herbicide-treated plots had fewer rice plants than the 42 days weedy and weed-free plots when rain occurred before crop emerge' .
