PROBLEM TO BE SOLVED: To adjust a fertilization amount on the basis of an angle of a fertilization boom in a field.SOLUTION: A work vehicle comprises: a travel vehicle body 2； a position information acquisition device for acquiring position information of the travel vehicle body； a growth state detector for detecting a growth state of a raised object； a controller for associating the acquired position information and data on the detected growth state of the raised object and storing the same； and a fertilizer 100 provided on the travel vehicle body, in which right and left fertilization booms of the fertilizer are rotatably moved between a position in a storage state along a side of the travel vehicle body and a position in a fertilization work state where the boom is protruded to a lateral direction of the travel vehicle body, and movement angles (folding angle) of the left fertilization boom 110L and right fertilization boom 110R are configured so that the fertilization booms can be independently rotated at the angles and when the movement angle is varied, a dispersion amount control according to the movement angle can be performed.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2020,JPO&INPIT【課題】圃場における施肥ブームの角度に基づき、施肥量を調整すること。【解決手段】走行車体２と、走行車体の位置情報を取得する位置情報取得装置と、育成物の生育状況を検知する生育状況検知装置と、取得された位置情報と、検知された育成物の生育状況に関するデータとを対応づけて記憶させる制御装置と、走行車体に設けられた施肥装置１００とを備え、施肥装置の左右の施肥ブームは走行車体の側方に沿った収納状態の位置と走行車体の左右方向に突き出した施肥作業状態の位置との間を回動自在に移動し、左側の施肥ブーム１１０Ｌと右側の施肥ブーム１１０Ｒの移動角度（折り畳み角度）は、それぞれ独立して回動可能であり、移動角度を変更した場合は、移動角度に応じた散布量制御を可能とする。【選択図】図１
