The greenhouse, nursery, and sod (GNS) sector in the United States accounted for $10 billion in gross sales or 5% of gross farm receipts, in 1998. Despite its significant economic contributions, the sector receives little attention from policymakers. Part of the problem lies in the absence of empirical economic analysis that addresses the impact of the sector on the U.S. economy. The absence of such analysis places the sector at a disadvantage when agricultural policies are designed to address agricultural imbalances, such as farm income problems, and hinders the ability of the sector to lobby for policies favorable to GNS producers. This study provides estimates of the economic impacts of the GNS sector on the U.S. economy and quantifies the linkages between the GNS sector and other economic sectors. The results show that the sector contributed over $26 billion and $17 billion in output and value added economic activity, respectively, and over 438,000 jobs.

Yield in most crops can be increased with closer in-row spacing; however, the costs vs. benefits need to be assessed. A partial economic analysis was conducted at various plant spacings and harvest times to determine the best cultural management strategy. The effect of plant spacings (15.2, 22.9, 30.5, and 38.1 cm) and two dates of harvest (≈110 or 130 days after planting) were studied on `Beauregard' sweetpotato in one planting in 1991 and two planting locations in 1992. Weights were obtained for the U.S. Number 1, canner, jumbo, and cull grades. The 30.5-cm spacing interval was used as the standard comparison for economic analysis. Yields of sweetpotatoes increased as in-row spacing decreased. Based on economic analysis, the 38.1-cm spacing was always inferior to the 30.5-cm spacing. The preferred in-row spacing of `Beauregard' sweetpotato is 22.9 if a late harvest is anticipated, while the 15.2-cm spacing would be best if harvesting at ≈110 days after transplanting. As long as moisture is not limiting and planting is before mid-June, sweetpotato growers should place `Beauregard' plants at an in-row spacing of 15.2 or 22.9 cm, depending on projected date of harvest, to obtain the best yields with the highest marginal return on investment.

Several common methods of post harvest handling and pre-cooling for fresh market bunched greens (turnips, smooth and curly mustard, and collards) were evaluated. Six treatments were evaluated where greens were rehydrated and precooled using different combinations of hydrocooling, slush ice, and shoveled ice with three rehydration methods (hydrocooling, water drench, and water floating). Product temperatures were monitored and overall quality ratings were made after seven days in cold storage. Product quality after seven days was best with hydrocooling and insignificant differences in quality were recorded whether in-box ice was shoveled or slush ice. Turnips were most sensitive to degradation if precooled inadequately. Collards were the least sensitive. Economic analysis was completed using labor and ice cost differentials of selected packing and cooling methods to calculate product volume levels required to amortize relatively high costs of the hydrocooler, slush icer, and ice machine. Extremely large volume is required to fully amortize equipment acquisition costs based on labor cost savings alone. Greater cost savings per box, when comparing the cost of purchased ice to homemade ice, resulted in much lower volume requirements for full amortization. The results indicate that a producer with limited capital would benefit the most economically from acquiring an ice machine. The greatest quality benefit is gained from precooling with the hydrocooler.
