In a Nutshell
• Three farmers provided enterprise
budgets for cucumber production in
2016.
• Cucumbers were grown in a heated
greenhouse (Ann Franzenburg), an unheated
high tunnel (Emma Johnson),
and an open field (Jan Libbey).
• Franzenburg, Johnson, and Libbey also
provided enterprise budgets for year
one of this study in 2015.
Key Findings
• Labor was the largest expense for
Johnson and Libbey, accounting for
74% and 94% of their total expenses,
respectively. Labor was only 40% of
Franzenburg’s costs.
• Labor breakdown by task differed at
each farm. The largest tasks on each
farm, measured in hours, were: pruning
and trellising at Franzenburg, field
maintenance at Johnson, and harvesting
and packing at Libbey.
• Production in the greenhouse at Franzenburg’s
provided highest yield (lb
fruit/ft2) and number of fruit per ft2.
• Among the three farms, outdoor production
at Libbey’s had the highest net
income per pound.

Three farmers provided enterprise
budgets for cucumber production.
• Cucumbers were grown in a heated
greenhouse (Ann Franzenburg), an unheated
high tunnel (Emma Johnson),
and an open field (Jan Libbey).
Key Findings
• Labor was the largest expense for all
farms, ranging from 56% of enterprise
expenses to 93%.
• Trellising and pruning were the biggest
labor task for Ann, while harvesting
and packing was the largest portion of
labor for Emma and Jan.
• Production in the heated greenhouse
at Ann’s provided highest yield (lb
fruit/ft2) and number of fruit per ft2,
and also the highest net income per ft2
and per fruit.
• Among the three farms, outdoor
production at Jan’s had the highest net
income per pound.

We compare the energy use of winter
high tunnel production to the product
revenue during the first season of
operation.
• Greenhouses and high tunnels allow
farmers to extend the growing season.
• Greenhouses and high tunnels can
increase revenue per square foot.
• Managed properly, the increased
revenue can offset the expense of
additional infrastructure.
• In the first winter of production, Lee’s
Greens was able to keep their revenue
above their energy costs.
• Propane was the bulk of the energy
expenditure.
