How to say "productive" in Japanese

• 豊饒ほうじょうCommon
  na-adjective, nounCovers 'productive' only in the fertile, fruitful sense: land or soil that yields abundantly. It does not describe a person's or an organization's output; that is a different sense of the English word.
• 生産的せいさんてき
  na-adjectiveThis is the word for 'productive' in its everyday sense: work, activity, or discussion that yields useful results. Use it when you want to say that a person, an effort, or a period was productive.
• プロダクティブ
  na-adjectiveA katakana borrowing of the English word, and only a marginal way to say it; you will seldom need this one, as 生産的 is the usual choice for this sense.
• 肥沃ひよく
  na-adjective, nounReally means fertile or rich, and 'productive' only in that soil sense: fertile, rich land. It never describes people or their work, so for a productive worker this is not the word.
  肥沃ひよくな土壌どじょうは豊ゆたかな作物さくもつを産さんする。↗

  Rich soil yields good crops.
• 多作たさく
  no-adjective, na-adjectiveCovers 'productive' for creative output: a prolific writer or artist who turns out many works. It describes a person's output, not fertile land or a productive day at work.

Use 生産的 for productive work or activity, 多作 for prolific writers and artists, 豊饒 and 肥沃 for fertile, fruitful land, and treat 「プロダクティブ」 as a marginal loanword.
