The answer should be manufacturing. During the creation of the federal government, one of the key questions to arise was the centralisation and extent of power. This debate was well highlighted in the differing views of Thomas Jefferson, who believed federal government should support an agrarian (farming) economy and give more power to the states, while Alexander Hamilton stood for a federal government supporting industry and banking, as well as being the superior power.
Currently, the strongest branch of America's government is the Executive branch.
While the branches were once co-equal, the Presidency has taken on a life of its own with the ability to wage war without Congressional approval and to dictate the terms to Congress without much push back.
A shortage of crops/food would have killed off the soldiers mostly, devastating the southern states. I hope this helped!
