It seems like you're discussing aspects of colonial history, particularly regarding New Jersey and the agricultural practices of the Middle Colonies.
In the context of early American colonies, the term you might be referring to when you mention "Response area" may actually be "proprietary colony." New Jersey was indeed a proprietary colony, established in the 17th century when it was granted to individuals in return for a yearly payment (or rent) to the British crown. The proprietary system allowed individuals to manage their own lands and govern the colonies.
The Middle Colonies, which included New Jersey, New York, Pennsylvania, and Delaware, were known for their fertile soil and favorable climate, which allowed them to become significant agricultural producers. The crops you mentioned, such as wheat, barley, and rye, were indeed staples grown in this region. These crops were often referred to as "breadbasket crops" because they were central to the diet of colonists and could be sold in markets, contributing to the economy.
