The studies focus primarily on production costs in the counties of Yolo, Solano, Sacramento and San Joaquin. The two separate studies list estimated production costs for growing transplanted processing tomatoes under furrow irrigation and under sub-surface drip irrigation on 60-inch beds.
The major differences between the two companion studies are inputs related to irrigation and tillage and from yield outcome.
Each analysis is based upon a hypothetical farm operation using practices common to the region. Input and reviews were provided by growers, pest control advisers and other agricultural associates. Assumptions used to identify current costs for individual crops, material inputs, cash and non-cash overhead are described. 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.
These two studies –“Sample Costs to Produce Processing Tomatoes, Sub-Surface Drip Irrigated (SDI) in the Sacramento Valley & Northern Delta - 2014” and “Sample Costs to Produce Processing Tomatoes, Furrow Irrigated in the Sacramento Valley & Northern Delta - 2014” – and other sample cost of production studies for many commodities are available and can be downloaded from the Agriculture and Resource Economics Department website, http://coststudies.ucdavis.edu.
