I am curious about this old photo like all photos I come across.  What I assume about this photo……

• The gentleman is a farmer.
• He is either water or fertilizing the plant.
• Another option, the plants have a bug or slug; the farmer is applying a pesticide.
• The area looks dry.
• I like the fence around the garden which would aid in keeping bunnies away.

Other than that, I have no other ideas on what the farmer is doing. If he is watering each plant, the task would be time consuming.  The garden appears to be a large one.
