Factors Affecting Yield
- Soil fertility — compost-rich soil boosts yields 30–50%.
- Watering — consistent moisture is critical for fruiting crops.
- Sun exposure — most vegetables need 6–8 hours of direct sun.
- Pest pressure — yields can be cut in half by unmanaged pests.
- Variety choice — hybrid varieties typically out-yield heirlooms 2:1.
