PROBLEM TO BE SOLVED: To properly manage a load capacity of a harvested material transported by a transport vehicle as crop yield information when the harvested material being harvested by a harvester is transferred to the transport vehicle and transported.SOLUTION: A crop yield management system is configured so as to freely transfer a harvested material being harvested by a harvester 1 to a transport vehicle 50 while the harvester 1 for harvesting crops and the transport vehicle 50 are traveling side-by-side. The crop yield management system includes an association unit for performing association processing to associate the crop yield information detected in a crop yield detection unit in a side-by-side travel state as a load capacity of the harvested material transported by the transport vehicle 50 being in a side-by-side travel state, when a determination is made that the harvester 1 and the transport vehicle 50 are in the state of side-by-side travel, based on the harvester position information being acquired in a harvester position information acquisition unit and the vehicle position information being acquired in a vehicle position information acquisition unit.SELECTED DRAWING: Figure 2【課題】収穫機にて収穫された収穫物を運搬車両に移し変えて運搬する場合に、その運搬車両にて運搬される収穫物の積載量を収穫量情報として適切に管理すること。【解決手段】作物を収穫する収穫機１と運搬車両５０とが併走状態にて収穫機１にて収穫された収穫物を運搬車両５０に移し変え自在に構成され、収穫機位置情報取得部にて取得される収穫機位置情報と車両位置情報取得部にて取得される車両位置情報とに基づいて、収穫機１と運搬車両５０とが併走状態であると判定すると、併走状態において収穫量検知部にて検知される収穫量情報を、併走状態である運搬車両５０にて運搬される収穫物の積載量として関連付ける関連付け処理を行う関連付け部が備えられている。【選択図】図２
