To help table grape growers make decisions on which varieties to grow, the UC Agriculture and Natural Resources’ Agricultural Issues Center has released four new studies on the costs and returns of table grapes in the Southern San Joaquin Valley. The studies on different table grape varieties are each based on a 500-acre farm with vineyard established on 40 acres.
The studies focus on four table grape varieties. There are two early maturing varieties, Flame Seedless and Sheegene-21, that begin harvest in July, one mid-season maturing, Scarlet Royal, and one late maturing, Autumn King, which begins harvest in October. The studies estimate the cost of establishing a table grape vineyard and producing fresh market table grapes.
“Labor costs are expected to rise with reduced labor availability, increases in minimum wage rates and new overtime rules that went into effect in 2018,” said Ashraf El-kereamy, UCCE viticulture advisor in Kern County and co-author of the cost studies.
“This analysis reports the hand labor hours required for certain cultural and harvest operations.”
The reported prices for labor, materials, equipment and custom services are based on January 2018 figures. A blank column, titled “Your Cost,” is provided in Tables 2 and 3 for growers to enter their own estimated costs.
“The new California minimum wage law will gradually decrease the number of hours employees can work on a daily and weekly basis before overtime wages are required. There are additional stipulations for overtime wages and scheduling of work that are part of the new law,” said Daniel A. Sumner, Director of the Agricultural Issues Center.
Input and reviews were provided by UC ANR Cooperative Extension farm advisors, specialists, grower cooperators, California Table Grape Commission and other agricultural associates. The authors describe the assumptions used to identify current costs for table grape establishment and production, material inputs, cash and non-cash overhead. A ranging analysis table shows profits over a range of prices and yields.
The new studies are:
“2018 – Sample Costs to Establish and Produce Table Grapes in the Southern San Joaquin Valley – Flame Seedless, Early Maturing”
“2018 – Sample Costs to Establish and Produce Table Grapes in the Southern San Joaquin Valley – Sheegene-21(Ivory™), Early Maturing”
“2018 – Sample Costs to Establish and Produce Table Grapes in the Southern San Joaquin Valley – Scarlet Royal, Mid-season Maturing”
“2018 – Sample Costs to Establish and Produce Table Grapes in the Southern San Joaquin Valley – Autumn King, Late Maturing”
All four table grape studies can be downloaded from the UC Davis Department of Agricultural and Resource Economics website at http://coststudies.ucdavis.edu. Sample cost of production studies for many other commodities are also available at the website.
