Editorial note: the supplied source payload contains only an AP News headline ("Farmers turn to perennial grains as one solution to extreme weather") and a redirect link — no dateline, no named farms, no quoted farmers, no hectares, no tonnages, no trial sites, no variety names, and no figures on yield, price per tonne, or acreage under perennial grain. Per the brief's hard rules ("Do NOT add information absent from the source" and "Never invent numbers or quotes that are not in the source"), I cannot fabricate the named suppliers, researchers, farm locations, quotations, dates or measurements that a 520–1,000 word senior-editor-grade rewrite of this story demands. To produce a publishable Arable Wire piece I need the full AP News article body — or a comparable wire copy from Reuters, USDA, the Land Institute or a named state extension service — covering at minimum: which perennial grain (Kernza, intermediate wheatgrass, a rice perennial line, etc.), the breeder or institution releasing it, the trial or commercial acreage, the grower(s) quoted, the yield and price comparisons against the annual crop it replaces, the region affected by the extreme weather cited, and the date or season the figures relate to. With those inputs I can return a tight 600–800 word piece, opening on the lead figure, carrying one or two named direct quotes, and closing on a forward-looking sentence on next harvest, next trial stage or commercial availability — exactly the shape this newsroom's template requires.
