Vegetable Crop Yields, Plants per Person, and Crop Spacing

Sharing is caring!

Vegetable crop yields and the number of vegetable plants to grow for each person in your household will help you estimate the space needed for a home vegetable garden.

Crop yield estimates and consumption predictions are primarily based on experience. Keeping a food log and garden record can help you hone your vegetable garden needs and make for more thoughtful planning.

Vegetable crop yields will vary according to garden conditions and the variety planted. Weather and growing conditions can change from year to year, and these changes can affect yield.

Estimating vegetable crop yields

Estimating a crop yield before harvest can aid in planning the use of your garden space. Estimating how much each person in your household consumes will also help you determine how much to plant. Knowing how much space each plant requires and when it will reach harvest will help you determine how much space to set aside for each crop and when.

Crop yield estimates and consumption predictions are primarily based on experience. Your vegetable needs may change from year-to-year.

Keeping a food log will help you determine how much to grow for your household. Record how often you eat lettuce, for example, and you will soon determine how much to grow. Do you eat tomatoes fresh or do you process and freeze them for winter use–or both? A food log is a simple way to learn about your eating habits and preferences.

Estimating yield method

To estimate crop yields in your garden, follow these steps:

  1. Select a 10-foot section of a row to measure your harvest. If you plant wide rows or intensive beds, measure plantings and harvest by the square foot.
  2. Note the number of plants growing in the measured section. Be sure to note the cultivar or variety of plants you are growing. Differing cultivars can vary in yield.
  3. Harvest the crop from the measured section.
  4. Weigh the sample harvest for total yield; you can also count the yield bean-by-bean or tomato-by-tomato.
  5. Record the results so that you can plan and compare the results to future harvests.

Yields will vary according to garden conditions and the variety planted. Weather and growing conditions can change from year to year; these changes can affect yield.

Choosing crops to plant

Here are important considerations in choosing crops for planting in the home garden:

  1. Grow what you will eat or what you can store or give away. Overplanting requires time, energy, and natural resources.
  2. Grow what you can’t buy. Grow crops that are hard to come by at the farmers’ market or grocery store. Choose varieties recommended by friends and neighbors.
  3. Grow crops that are expensive to buy at the farmers’ market or grocery store but easily grown at home.
  4. Grow what tastes best home-grown. Peas and sweet corn taste much better fresh from the garden.

Crop-by-crop yield estimator

Here are crop yield estimates, plants-per-person suggestions, and crop spacing requirements to help you estimate your garden space requirements and growing requirements. A note regarding crop spacing: There are two ways to plant vegetables: (1) traditional rows–single plant rows with space between each row for walking or for moving a tractor through the field; (2) narrow bed, wide rows where plants are space across a narrow bed 24 to 26 inches wide in wide rows where plants are spaced equidistant from one another. The advantage of wide-row planting: you will grow two to three times more than you would grow in a traditional row.

The following illustration shows how plants are set equidistant in wide rows.

Here lettuce is planted in a narrow bed (36 inches across) and wide row–.each plant is equidistant from the next–6 inches apart in all directions.

How to value vegetable crop quality

How do you put a value on your vegetable garden and the crops you grow? It depends upon what you want in return for the time you spend and the space your garden requires.

Fresh vegetables. If you want a steady supply of fresh vegetables for the table, make small successive planting over several weeks or a month or two so that your crops will come to harvest in small quantities and can be taken fresh to the table at harvest.

Here are ways to value your vegetable harvest:

  • Flavor. If you are gardening for flavor, grow crops that you can pick at their peak and serve immediately. These are crops that do not store well, and that will lose flavor in even a few days: tomatoes, sweet corn, and peas.
  • Storing. If you are growing to keep vegetables on hand over several weeks or months, choose vegetables that will not lose flavor or texture when kept in the refrigerator or pantry: cabbage, potatoes, and dry onions.
  • Freezing, canning, or drying. If you plan to preserve your crops for long-term use, you will need larger quantities of a crop and all of the crops should come to harvest at the same time.

High-value home-grown vegetables

Here’s my list of crops that will give you very good value for your time, effort, and space.

  • Tomatoes: Grow two plants for each person in the family.
  • Bush beans: Grow 5 feet of row for each person.
  • Beets: Grow 2 feet of row for each person, but sow several times in succession.
  • Carrots: Grow 2 feet of row for each person; make several sowing.
  • Lettuce: Grow 3 feet of row for each person; make three sowings.
  • New Zealand spinach: Grow 2 feet of row for each person.
  • Radishes: Grow 1 foot of row for each person; make 3 or 4 succession sowings.
  • Swiss chard: Grow 3 feet of row for each person.

Agronomists at Washington State University Extension compared the relative quality, productivity, and monetary value of commonly homegrown vegetables. They made three comparisons: 1) the quality of garden-grown crops to store-bought crops; 2) the crop yield to the square feet required to grow the crop; 3) the money saved by growing your own compared to the cost at the grocery store. A “High” rating is the best value.
