Which King in his 50-year reign fought no fewer than 34 wars?

Sargon

"A Semitic prince from the northern city of Akkad was Sargon the Great. By force of arms he conquered all the Sumerian states, the entire Tigris-Euphrates basin, and brought into being an empire that stretched from the Taurus Mountains to the Persian Gulf. Sargon united both halves of Mesopotamia for the first time since 4000 B.C.
As with most early Sumerian kings, we know little about Sargon the Great. Cuneiform records indicate that in his 50-year reign he fought no fewer than 34 wars. One account suggests that his core military force numbered 5,400 men; if that account is accurate, then Sargon's standing army at full mobilization would have constituted the largest army of the time by far."
