Research draft, second pass

A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description

Let an agent explain maize as a crop and plant, describe varieties and uses, support cultivation and food questions, and present biotechnology debates with attribution.

A cereal grass domesticated in Mesoamerica and now one of the most widely grown crops in the world, cultivated for grain, sweet corn, fodder, flour, oil, syrup and industrial products such as ethanol, in landraces and varieties from Andean and Bolivian maize to pod corn and genetically modified lines such as Bt maize; maize is central to food security, agriculture and culture in many regions and is regulated for seed, biotechnology and trade.

What it is for: A major cereal crop.

It can be explain the plant and crop; describe varieties and uses; support cultivation questions; present biotechnology debates.
