In spite of increased efforts to integrate nutrition and agriculture there are relatively few methods developed to effectively do so in the design and analysis of agricultural interventions. In order to develop and test a method to link agricultural production and nutritional benefits, fall gardens were planted by researchers and low‐income households in five locations in the New River Valley, Virginia. Edible portion yield per square meter was calculated as a basic nutrition/agricultural yield measure. In order to use a more discriminating measure, crop nutrient yield equivalents (CNYE) for limiting nutrients (vitamins A and C, iron, and calcium) were calculated. The CNYE indicates the number of days that 100% of the USRDA would be supplied. Summing the CNYE scores across nutrients provided a ranking of the overall nutritional completeness (ONC) of the crops. The ONC ranking thus supplies a measure of yield and nutritional efficiency that can be adapted for different nutrition requirements and gardening conditions.
