How to say "rain-fed (unirrigated farming)" in Arabic

As exact as cognates get, technical sense included: Hebrew בעל and Arabic baʿl are the very same word, 'lord, husband, owner' — and in farming, both languages use it for the identical specialized meaning: unirrigated, rain-fed land, as if the sky itself were its only master. חקלאות בעל and زراعة بعلية describe the same practice.
