This research focused the agriculture sector in almost all districts of Punjab, Pakistan. Land Productivity of four major crops: wheat, rice, cotton and sugarcane was evaluated to rank these districts on the basis of mechanized agriculture. Principal component analysis helped to construct technological components reflecting the contribution of various agricultural inputs. Higher land productivity in both wheat and cotton outputs proved significantly influenced through technological inputs.
