“By 1964, the new semi-dwarf wheat varieties developed in Mexico were grown on most of the country’s wheat lands. Mexico, which had previously imported half of its wheat, became self-sufficient and even began exporting wheat. These new varieties required intensive use of chemical fertilizers and controlled irrigation to achieve their high yields.”

Cevap
The correct answer states that Green Revolution technologies relied heavily on industrial inputs, such as chemical fertilizers and irrigation, to maximize crop yields.
