plow, cultivate
畊 centers on working the land: plowing fields and cultivating soil to grow crops.
畊 combines 田 (field) with 井 (well), suggesting the agricultural connection between fields and irrigation. It is a variant form of 耕, where 耒 (plow) is replaced by 田.
A field 田 beside a well 井: picture a farmer plowing the field, drawing water from the well to cultivate the crops.
For キョウ, imagine a farmer in Kyoto (京都, きょうと) plowing a field: Kyoto -> キョウ, and the well-watered field is being cultivated.
