Southern highbush blueberries (Vaccinium corymbosum × V. darrowii hybrids) are a rapidly emerging crop with a bright future in Georgia; however, blueberries, like other fruit crops, are subject to price and yield fluctuation. These volatilities depend on several factors, including the cultivar produced and sold (i.e., fresh or frozen), locality, aggregate productivity, targeted market, and timing. As a result, profit margin is hard to determine. The objective of this study was to estimate total costs of cultivating southern highbush blueberries in soil under Georgia conditions and determine profitability, if any. Although there are several methods of profit determination, the risk-rated method was adopted for this study. The first-year establishment and maintenance cost of growing southern highbush blueberry in soil in Georgia using high organic matter (greater than 3%) spodic-type or allied sand soil series with supplemental pine bark incorporated was estimated at $9585.55/acre. The second-year establishment and maintenance cost of growing, harvesting, and marketing was $3691.99/acre less return from receipts of $2375.00/acre equal to $1316.99/acre. The third-year establishment and maintenance cost was $7068.20/acre. The total returns for the same year were $9500.00/acre. Subtracting the cost of $7068.20 from $9500.00 gives a net return of $2431.80/acre. The fourth-year cost, which was considered to be the first year of actual full production, was estimated at $13,547.35/acre. The compounded and recaptured establishment annual costs were $2176.43/acre. The risk-rated expected returns over total costs 66% of the time were $5452.65/acre. The chances of making profit were 92% and the base-budgeted net revenue was $6456.00/acre. Total budgeted cost was $3.38/lb. The estimated annual total fixed machinery cost was $290.41/acre. Total annual cost of solid set irrigation was $657.81/acre.

Rabbiteye blueberry (Vaccinium ashei) is the most important type of blueberry grown in Georgia. This species is classified as a highbush blueberry type, but is distinctively different from highbush blueberry (V. corymbosum) in its ability to withstand high temperatures and low-organic–matter soils. However, rabbiteye blueberries, like other fruit crops, are subject to price and yield fluctuation. These volatilities depend on several factors, including the cultivar produced and sold, locality, aggregate productivity, targeted market, and timing. As a result, profit margin is hard to determine. The objective of this study was to estimate economic returns using risk-rated budget analysis for rabbiteye blueberry under Georgia conditions. The first-year establishment and maintenance cost of growing rabbiteye blueberry in Georgia was estimated at $5022.04/acre. Total harvesting and marketing cost in the second year was $719.44/acre. In the third year, total variable and fixed cost was $3487.50/acre. In the full production year (fourth year), the cost was estimated at $4671.17/acre. The compounded and recaptured establishment annual cost was $2736.11/acre. The risk-rated expected returns over total costs 63% of the time were $679.00/acre. The chances of making a profit were 77% and the base budgeted net revenue was $369.00/acre. The total budgeted cost was $0.94/lb. The estimated annual total fixed machinery cost was $698.00/acre. The total annual cost of drip irrigation was $161.15/acre.

Two peach cultivars (Flordaking & Junegold) were planted in wheel-spoke design under a center pivot irrigation system. Main plots were sprays (Blast, Cheek, & Piggy-back) and cultivars. Sub-plots were training systems (Inside, Outside, & Standard). Sub-sub-plots were tree areas. Four rows were planted with two Inside rows and two Outside rows. Middle two rows of the standard plots were harvested. Intra-row spacing increased the further they were from the center. All trees harvested in 1990, standard plots were harvested every year, and Inside/Outside were harvested in alternate years. Most sources of variation in the model failed to be homogeneous among the 3 years. Since the number of trees harvested each year varied, all mean comparisons were done using the unequal N - unequal variance t-test.
