INTRODUCTION

Sample costs to produce oriental cucurbits - moqua / opo in the San Joaquin Valley are shown in this study. The study is intended as a guide only, and can be used to make production decisions, determine potential returns, prepare budgets and evaluate production loans. The practices described are based on production operations considered typical for this crop and region, but will not apply to every farm. Sample costs for labor, materials, equipment and custom services are based on current figures. “Your Costs” columns in Tables 1 and 2 are provided for entering your farm costs.

The hypothetical farm operations, production practices, overhead, and calculations are described under the assumptions. For additional information or an explanation of the calculations used in the study call the Department of Agricultural and Resource Economics, University of California, Davis, California, (530) 752-3589 or the local UC Cooperative Extension office.

ASSUMPTIONS

The assumptions refer to Tables 1 to 7 and pertain to sample costs to produce oriental cucurbits - moqua / opo in the San Joaquin Valley.  The cultural practices described represent production operations and materials considered typical for a small farm in the region.  Costs, materials, and practices in this study will not apply to all farms.  Timing of and types of establishment and cultural practices will vary among growers within the region and from season to season due to variables such as weather, soil, and insect and disease pressure. The use of trade names and cultural practices in this report does not constitute an endorsement or recommendation by the University of California nor is any criticism implied by omission of other similar products or cultural practices.

Farm.  This report is based on a 10 contiguous acre farm. The land is rented and planted to Asian vegetables.  In this study two acres are planted to cucurbits – moqua and/or opo – and the remaining acres to other Asian vegetables.  The grower and family do the majority of the labor for the operations, but a labor cost (opportunity cost) is shown for each operation.

Production Operating Costs

Land Preparation.  A custom operator plows the land one time, discs two times and lists the beds in January.  After listing, the bed peaks are flattened using the grower’s tractor and a nine-foot pipe (3 rows) towed behind the tractor.   Black plastic is then laid by hand (2 persons), or with a mulch machine, on alternate beds.

Plant.  The cucurbit seed – Moqua, Opo - is saved from the previous year and planted in the greenhouse sometime during December to January.  The plant trays hold 50 plants per tray and take about 20 minutes per tray to plant.  The germinated plants are planted in the field around March 15.  Opo and moqua are planted on alternate 36-inch beds with a six-foot in row spacing at 1,210 plants per acre. Holes for the plants are burned or punched in the plastic as the person plants.  Rows are usually 250 to 300 feet long.  Two people (16 man hours) plant one acre per day. 

Irrigation.  Irrigation includes the water costs and irrigation labor.  Lay-flat poly pipe is laid at the end of the rows and the water is run down the furrows. Irrigation begins in March two to three days after planting.  The field is irrigated every five days during March, April and May, every three days during June, July, August, and September and once a week during October.  Water at $2.50 per irrigation is assumed to be a typical cost. Water costs were provided from the growers pumping charges for the summer months.  Assuming the crop uses 30 acres-inches per season, this equates to a cost of $4.83 per acre-inch.  Irrigation labor is calculated as one-half hour per acre per irrigation. 

Fertilization.  The crop is fertilized at planting with 20-20-20 dissolved in water at three ounces of liquid fertilizer per plant or one 25-pound bag per two to three acres.  (10 pounds per acre in this study).  The fertilizer is placed in the planting hole at planting. Labor costs for applying the fertilizer are included in the planting labor.  One or two more fertilizations with UN32 at 5 gallons (55 lbs) per acre per application is typical – May and July.  Labor costs for UN32 fertilization are included in the irrigation costs.

Trellis System.  Six-foot stakes (reusable) are pounded in the ground at six-foot spacing; netting is attached to the stakes to form a trellis that the plants will grow up.  It takes two persons one day (8 hours) per acre to pound the stakes and an equal amount of time to install the net.  The trellis is removed at the end-of-the season.  See Field Cleanup.

Pollination.  Bees are required for pollination, but for the small acreage involved, the grower relies on wild/native bees for pollination.

Pest Management. The pesticides, rates, and application practices mentioned in this cost study are listed in the UC IPM Pest Management Guidelines – Cucurbits. Pesticides mentioned in this study are not recommendations, but those commonly used in the region. For information and pesticide use permits, contact the local county Agricultural Commissioner’s office. For information on other pesticides available, pest identification, monitoring, and management, visit the UC IPM website at www.ipm.ucdavis.edu.  Pest control costs can vary considerably each year depending upon local conditions and pest populations in any given year.  Adjuvants are recommended for many pesticides for effective control and are an added cost.  The adjuvants in this study are not included as a cost in all applications.

Weeds.  The furrows are hand sprayed using a backpack sprayer with Roundup in April or May and in August.  To mix and apply the herbicide takes about 1.5 hours per acre per application for a total of three hours.  The field is hand weeded in March and May  at 1.5 hours per weeding to remove the weeds not controlled by the spray and /or black plastic.

Insects.  Lannate, Dipel or some other insecticide is applied in May and August to control worms and/or aphids.  Spider mites are treated with oil or soap sprays in July.  The material is applied with a backpack sprayer and takes about two-hours per acre to apply.  Nematodes can be a problem, but are usually not treated.

Diseases.  None

Harvest.  The crop is harvested June 15 through October 30.  The moqua and opo vegetables are packed in 40-pound boxes.  The field is harvested twice a week for deliveries to the packinghouse and once per week for farmer’s market deliveries.  It is assumed that one person can pick 2.5 forty-pound boxes per hour.  The grower in this study delivers the product to the packinghouse using a pickup and trailer.

Yields.  Yields for moqua and opo are very similar.  The crop yields an average of 2.4 boxes per week per row or 69 boxes per acre per week per row.  The crop yield used in this study is 1,250 forty-pound boxes per acre; however yields can be as high as 2,320 forty-pound boxes. 

Returns.  The returns in this report are an average based on mid-month USDA Agricultural Marketing Service Wholesale Fruit and Vegetable Reports for the months of June through October.   The average return less 30% for various costs above grower returns over the five months is $8.75 per 40-pound box for moqua and opo.  A price of $6.00 per box is used in this study to show various prices over a range of yields.  At the above price and yield, the grower shows a loss.  It is typical for the grower and family to provide most of the labor; therefore, deducting grower labor costs assumed to equate to $6,000 will provide the grower with a net profit.

Field Cleanup.  In October after the last harvest, the plants are chopped by hand, and the stakes, netting, and mulch are removed.  One person can chop the plants and remove the mulch at the rate of three 250-foot rows per eight-hour day (approximately 80 hours per acre). 

Pickup/ATV.  Costs for a 1/2-ton pickup are included in the study.  The pickup and a trailer are used for hauling the harvested cucurbits to the packing shed and are included in that cost.  In addition, the grower drives another 250 miles per acre for farming purposes.

Labor. Labor rates of $12.42 per hour for machine operators and $9.32 for general labor includes payroll overhead of 38%. The basic hourly wages are $9.00 for machine operators and $6.75 for general labor.  The overhead includes the employers’ share of federal and California state payroll taxes, workers' compensation insurance for truck crops (code 0172), and a percentage for other possible benefits. Workers’ compensation costs will vary among growers, but for this study the cost is based upon the average industry final rate as of January 1, 2005 (California Department of Insurance). Labor for operations involving machinery are 20% higher than the operation time given in Table 1 to account for the extra labor involved in equipment set up, moving, maintenance, work breaks, and field repair.

Equipment Operating Costs.  Repair costs are based on purchase price, annual hours of use, total hours of life, and repair coefficients formulated by American Society of Agricultural Engineers (ASAE).  Fuel and lubrication costs are also determined by ASAE equations based on maximum Power Take Off (PTO) horsepower, and fuel type.  Prices for on-farm delivery of diesel and gasoline are $1.51 and $2.05 per gallon, respectively.  The cost includes a 2% local sales tax on diesel fuel and 8% sales tax on gasoline.  Gasoline also includes federal and state excise tax, which are refundable for on-farm use when filing your income tax.  The fuel, lube, and repair cost per acre for each operation in Table 1 is determined by multiplying the total hourly operating cost in Table 6 for each piece of equipment used for the selected operation by the hours per acre.  Tractor time is 10% higher than implement time for a given operation to account for setup, travel and down time.

Interest on Operating Capital.  Interest on operating capital is based on cash operating costs and is calculated monthly until harvest at a nominal rate of 7.65% per year.  A nominal interest rate is the typical market cost of borrowed funds.  The interest cost of post harvest operations is discounted back to the last harvest month using a negative interest charge.

Risk. Production risks should not be minimized. While this study makes every effort to model a production system based on typical, real world practices, it cannot fully represent financial, agronomic and market risks, which affect the profitability and economic viability.

Cash Overhead

Cash overhead consists of various cash expenses paid out during the year that are assigned to the whole farm and not to a particular operation.  These costs include property taxes, interest on operating capital, office expense, liability and property insurance, and investment repairs.

Property Taxes.  Counties charge a base property tax rate of 1% on the assessed value of the property.  In some counties special assessment districts exist and charge additional taxes on property including equipment, buildings, and improvements.  For this study, county taxes are calculated as 1% of the average value of the property.  Average value equals new cost plus salvage value divided by 2 on a per acre basis. 

Insurance.  Insurance for farm investments varies depending on the assets included and the amount of coverage.  Property insurance provides coverage for property loss and is charged at 0.69% of the average value of the assets over their useful life.  Liability insurance covers accidents on the farm and costs $429 for the entire farm.

Office Expense.  Office and business expenses are estimated at $10 per acre.  These expenses include office supplies, telephones, bookkeeping, accounting, and legal fees.  The cost is a general estimate and not based on any actual data.

Land Rent. The 10 acres are rented for cash at $300 per acre.  The rented land includes the irrigation system that is maintained by the landlord.  Land rents range from $250 to $350 per acre.

Investment Repairs.  Annual maintenance except for the greenhouse (20%) is calculated as two percent of the purchase price.

Non-cash Overhead

Non-cash overhead is calculated as the capital recovery cost for equipment and other farm investments. 

Capital Recovery Costs.  Capital recovery cost is the annual depreciation and interest costs for a capital investment.  It is the amount of money required each year to recover the difference between the purchase price and salvage value (unrecovered capital).  It is equivalent to the annual payment on a loan for the investment with the down payment equal to the discounted salvage value.  This is a more complex method of calculating ownership costs than straight-line depreciation and opportunity costs, but more accurately represents the annual costs of ownership because it takes the time value of money into account (Boehlje and Eidman).  The formula for the calculation of the annual capital recovery costs is ((Purchase Price – Salvage Value) x Capital Recovery Factor) + (Salvage Value x Interest Rate).

Salvage Value.  Salvage value is an estimate of the remaining value of an investment at the end of its useful life.  For farm machinery (tractors and implements) the remaining value is a percentage of the new cost of the investment (Boehlje and Eidman).  The percent remaining value is calculated from equations developed by the American Society of Agricultural Engineers (ASAE) based on equipment type and years of life.  The life in years is estimated by dividing the wear out life, as given by ASAE by the annual hours of use in this operation.  For other investments including irrigation systems, buildings, and miscellaneous equipment, the value at the end of its useful life is zero. The salvage value for land is the purchase price because land does not depreciate.  The purchase price and salvage value for equipment and investments are shown in the tables.

Capital Recovery Factor.  Capital recovery factor is the amortization factor or annual payment whose present value at compound interest is 1.  The amortization factor is a table value that corresponds to the interest rate used and the life of the machine. 

Interest Rate.  The interest rate of 6.01% used to calculate capital recovery cost is the USDA-ERS’s ten-year average of California’s agricultural sector long-run rate of return to production assets from current income.  It is used to reflect the long-term realized rate of return to these specialized resources that can only be used effectively in the agricultural sector. 

Tools.  This includes shop tools, hand tools, and miscellaneous field tools.  The tools are an estimated value and not taken from any specific data. 

Irrigation.  The grower purchases lay flat vinyl pipe to deliver the water to the furrows.

Greenhouse.  The grower builds a greenhouse with PVC pipe and plastic to start the plants and for some plant storage.  The greenhouse is 20 feet x 20 feet.  The plastic cover may need to be replaced in one or two years.  The replacement cost is accounted for under Cash Overhead – Investment Repairs.

Equipment.  Farm equipment is purchased new or used, but the study shows the current purchase price for new equipment.  The new purchase price is adjusted to 60% to indicate a mix of new and used equipment.  Annual ownership costs for equipment and other investments are shown in the Whole Farm Annual Equipment, Investment, and Business Overhead Costs table.  Equipment costs are composed of three parts: non-cash overhead, cash overhead, and operating costs.  Both of the overhead factors have been discussed in previous sections.  The operating costs consist of repairs, fuel, and lubrication and are discussed under operating costs.

Table Values.  Due to rounding, the totals may be slightly different from the sum of the components.
