Postwar Productivity & the Green Revolution
High-yield genetics, fertilizers, irrigation, combines, poultry integration, no-till beginnings, global research networks, and massive productivity gains.
Scope
After World War II, agriculture entered an era of unprecedented productivity growth. The Green Revolution—led by Norman Borlaug and international research networks—developed high-yield wheat and rice varieties that dramatically increased global food production. Chemical fertilizers and pesticides became standard inputs. Combine harvesters, center-pivot irrigation, and integrated poultry operations transformed farm structure. No-till farming emerged as both a labor-saving technique and a soil-conservation strategy.
