What happened to the farming industry to make its production rise or fall in the post-WWII era?

Production has risen.

Explanation:

With the development of military technologies before and during World War II, it impacted agricultural production. Namely, the development of technology continued after the war, but investments were made to develop technology for economic benefit. By 1940, the government had invested about 30 million in the development of agricultural technologies. By 1946, laws were passed that expanded the studies of the agricultural department. The same law mandates food quality research. During that period, the government invested a lot in defense and space programs, but significant progress was made in agricultural production, which led to a significant increase in food production.
