The increase in crop yield has its limits.
It's not the limit of crop genetics, but the limit of the external environment.
Wheat, cotton, sugarcane, vegetables, and other crops may have the potential for improvement.
But rice, after many rounds of breeding blessings, has already reached its potential for improvement.
Currently, Origin City's rice can yield high crops solely by relying on excellent crops.
However, pests, fertilizers, soil, and climate are all external factors that reduce yields and have nothing to do with crop varieties.
The closer you get to the limit, the weaker Gwivelle's casting effects become.
There are ways to break through the limit.
Developing pesticides, synthesizing fertilizers, scientific dense planting, and hybrid breeding can break through the current limits and continue to improve agricultural yields.
