Nazareno Strampelli (May 29, 1866 in Castelraimondo, Italy – January 23, 1942) was an Italian agronomist and plant breeder. He was the forerunner of what became known as the Green Revolution of the late 1960s. Strampelli's work allowed Italy to become almost self-sufficient in bread wheat production, relative to Italy's contemporaneous population and consumption patterns, increasing area-based agricultural intensity from an average yield of 1.0 t/ha at the beginning of the 19th century to about 1.5 t/ha in the 1930s, through the hybridization of wheat into high-yield varietals.
