Do you know which veggies provide the best yield per square foot of growing space?
In urban gardening, space is naturally limited. So what to grow that will produce the greatest yield in the least amount of space is important to know.
Whether you’re urban gardening for yourself and family, or as an urban, suburban or rural farming business, it’s important to have an idea of what’s reasonable to expect in produce from your gardening and farming efforts.
There’s an old 1978 chart circulating—in fact most stats we’ve found online are using this old data. However those numbers have since been updated and tweaked between 2009 and 2012. An update was really needed since seeds and gardening methods are able to produce more today than when that research was conducted, and there are more urban gardeners today as well.
So here’s some more updated information. If you have even newer data, please let us know and we can adjust and tweak this to be as current as possible.
Yield Expectations for Mixed Stand, Small-Scale Agriculture
Excerpted from Rutgers Urban Fringe Report1)https://njaes.rutgers.edu/pubs/urbanfringe/pdfs/urbanfringe-v07n01.pdf
For anyone considering small scale farming for a living, whether supplemental at first or full time, it’s important to set realistic expectations based on averages available.
As a General Guideline, 1/2 lb per square foot is an average yield for Mixed crop, Small-Scale Agriculture.
Now to decipher profitability is another thing. You’d of course have to calculate estimated costs against the wholesale or Farmer’s Market price you could get per pound on the crops you’d like to grow to sell.
Let’s go a little deeper into crop yields and price comparisons next.
Small Scale Farming and Profitability
For example, a short foray into calculations reveals a yield of .4 lb per square foot for broccoli and 1.8 lbs per square foot for tomatoes.
As of this writing, the retail price from our local Harris Teeter grocer for organic vine ripened tomatoes for is $2.99/lb. Surprisingly it’s the same for broccoli.
Retail Price Per Square Foot
- Tomatoes @ 1.8 lbs per SF x $2.99 = $5.38
- Broccoli @ .4 lbs per SF x $2.99 = $1.20
So… tomatoes have the potential to earn approximately 77% more than the broccoli. Now remember, this is retail.
Without even knowing the wholesale and costs for growing, it’s easy to see that tomatoes are more profitable than broccoli. So, if you have limited space or can only produce one crop to start, it would more likely be tomatoes than broccoli.
In the book The Market Gardener there’s a very handy chart that outlines the typical annual sales profitability and rank by crop the author produced on his farm. Indeed there as well, tomatoes were ranked as number one in sales and high in profitability.
Conversely, broccoli was ranked as nine in sales and low in profitability. Mesculin mix greens were ranked number 2 in sales and high in profitability.
So this should give you an idea to get your mental juices flowing in calculating what’s possible for you.
If you’ll be selling at the Farmer’s Market, you’ll want to frequent your local one(s) and observe everything while keeping notes on prices.
Next, are you familiar with high tunnel farming?
High Tunnel Farming
Excerpted from UntiedtsWeGrowForYou.com
High Tunnel technology has been in use for many years. Tracing back to an apparent origin in Spain and France, people in these countries were making use of simple, low-cost metal framing and lightweight polyethylene covering material to form tunnel like structures over their crops. These structures protected their crops from the natural elements and extended their growing seasons.
The Untiedts family farm in Waverly, Minnesota, has been using high tunnel growing methods for 30 years… back before it was popular. High tunnels are about more than tall hoop houses, they also create their own microclimate system that incorporates pollinators such as bumble bees.2)http://www.untiedtswegrowforyou.com/high-tunnel-farming
