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.
“We included detailed costs for specialized hand labor of certain cultural and harvest operations.”
“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 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. Other tables show the monthly cash costs, the costs and returns per acre, hourly equipment costs, and the whole farm annual equipment, investment and business overhead costs.
