農作
The mechanization of farming is advancing.
農作 refers to agricultural production or crops in general, while 耕作 specifically denotes the act of tilling and working land; the two are easily confused because of the shared 作 and similar sound.
Compound of 農 (agriculture) and 作 (make, produce). The exact historical derivation is uncertain, but the kanji combination directly conveys the meaning of agricultural production.
