Agronomy nwere akụkọ ihe mere eme ogologo na ọgaranya nke malitere na Neolithic Revolution. A na-ahụ ụfọdụ omume mbụ nke agronomy n'ime mmepeanya oge ochie, gụnyere Egypt Ochie, Mesopotemia, China na India. Ha mepụtara usoro dị iche iche maka njikwa ọmụmụ ala, ịgba mmiri na ntụgharị ihe ọkụkụ.

N'ime narị afọ nke 18 na nke 19, ọganihu na sayensị dugara na mmepe nke agronomy nke oge a. Onye Germany na-ahụ maka ọgwụ Justus von Liebig na John Bennett Lawes, onye ọchụnta ego Bekee, nyere aka na nghọta nke nri na-edozi ahụ na kemịkalụ ala. Ọrụ ha bụ maka ịmepụta fatịlaịza nke oge a na ọrụ ugbo.
