A growth state estimation method comprising:

• acquiring a first image including a plant captured at a first time point and a second image including the plant captured at a second time point after the first time point;
• specifying a same specific part of the plant from each of the first image and the second image;
• and
• estimating a growth state of the plant by comparing a state of the same specific part included in each of the first image and the second image.

• when executed by the computer,
• acquiring a first image including a plant captured at a first time point and a second image including the plant captured at a second time point after the first time point;
• specifying a same specific part of the plant from each of the first image and the second image;
• and
• estimating a growth state of the plant by comparing a state of the same specific part included in each of the first image and the second image.
