An Economic Comparison of High Tunnel and Open-Field Strawberry Production in Southeastern Virginia and A Joint Estimation of Acreage Planted to U.S. Major Crops
… costs, and fuel ethanol production on the joint acreages planted to eight U.S major crops (barley, corn, cotton, peanuts, rice, sorghum, soybeans, and wheat). We found a positive and statistically significant marginal effect of the expected peanuts' revenue on its acreage share. The expected corn …
