Systems for Returning Conservation Reserve Progam Land to Wheat (Triticum aestivum) Production

摘要

Experiments were conducted near Duke and Forgan, OK, on land enrolle din the Conser- vation Reserve program (CRP) that had been seeded to Old World bluestem (OWB) to evaluate tilalge systems for returning CRP grassland to winter wheat production. Glyphosate controlled OWB 72/100 or less in no-till (NT) wheat. Disk tillage (DT) and moldboard plow tilage (MPT) for wheat seedbed preparation controlled OWB 87 and 99/100, respectively, at Forgan and 96 and 100/100, re- spectively, at Duke.
