収率 is a more general term for yield in chemical or industrial processes, while 歩留まり is specifically used in manufacturing and business for the ratio of good output to input.
Compound of 歩 (bu, 'walk' or 'rate') and 留まり (domari, from 留まる 'to stay' or 'to be fixed'), literally 'rate that stays'. The exact historical derivation is uncertain, but the term has been used in business and manufacturing since at least the early 20th century.
