How to Use the Vegetable Yield Calculator
- Enter the number of plants you are growing.
- Select the vegetable type from the dropdown.
- Input the expected yield per plant (or use defaults).
- Review total harvest weight, revenue estimate, and yield per square foot.
The Formula
Variable Definitions
- Plants: Total number of mature plants in the garden
- Yield per Plant: Average harvest weight per plant over the season (lbs)
- Loss%: Percentage lost to pests, disease, or damage (typically 5–20%)
- Revenue: Total value at the entered price per pound
Estimating Tomato Harvest from 20 Plants
Calculate expected yield and revenue for 20 indeterminate tomato plants.
- Step 1: Enter 20 plants, select Tomatoes, default yield 10 lbs per plant.
- Step 2: Set harvest loss to 10% for pest/damage losses.
- Step 3: Total yield = 20 × 10 × 0.90 = 180 lbs.
- Step 4: At $2.00/lb: Revenue = 180 × $2.00 = $360.
- Step 5: If planted in 100 sq ft: yield = 1.8 lbs/sq ft.
Frequently Asked Questions
How much does one tomato plant produce?
An indeterminate tomato plant produces 10–15 lbs per season. Determinate varieties produce 5–10 lbs. Yield depends on variety, growing conditions, and care. Proper staking, pruning, and watering maximize production.
What is the average yield per acre for common vegetables?
Tomatoes: 20,000–40,000 lbs/acre. Bell peppers: 15,000–25,000 lbs/acre. Lettuce: 15,000–25,000 lbs/acre. Carrots: 20,000–30,000 lbs/acre. Cucumbers: 15,000–25,000 lbs/acre. These vary significantly by region and management.
How do I increase vegetable yield per plant?
Use quality soil with compost, water consistently, fertilize appropriately, prune indeterminate varieties, use succession planting, and choose high-yield cultivars. Proper spacing, mulching, and pest management also significantly impact yield.
What is a good yield per square foot?
For intensive gardening: tomatoes 2–4 lbs/sq ft, peppers 1–2 lbs/sq ft, lettuce 0.5–1 lb/sq ft, beans 0.5–1 lb/sq ft. Square foot gardening with proper spacing and soil fertility achieves higher yields per square foot than row gardening.
How do I calculate garden revenue for selling produce?
Use local farmers market prices. Multiply total yield in pounds by price per pound. For community Supported Agriculture (CSA), estimate value of each crop variety and sum for total share value. Track actual sales for accurate revenue.
When is the best time to harvest for maximum yield?
Harvest at peak ripeness for maximum weight and flavor. For beans, pick every 2–3 days to encourage continued production. For tomatoes, pick when fully colored but firm. For root vegetables, harvest at mature size before second frosts.
Does succession planting increase total yield?
Yes, significantly. Plant new batches of quick crops (lettuce, radishes, beans) every 2–3 weeks throughout the growing season. This extends harvest and can double or triple total yield compared to a single planting.
How accurate are yield estimates?
Yield estimates are approximations based on average conditions. Actual yields vary by 20–50% depending on weather, soil, pests, and care. Use estimates for planning and purchasing, but expect real-world variation.
