Answer

Brief Explanations:

Planting varieties from the 1700s is not efficient as modern - bred varieties are more productive. Planting the same crop year - after - year can deplete soil nutrients. Improving agricultural technology can enhance efficiency. Reliable irrigation infrastructure helps in consistent growth. New herbicides can control weeds and thus increase efficiency.

Answer:

improving the available agricultural technology, improving the infrastructure to deliver reliable irrigation, introducing new herbicides (chemicals) to prevent growth
