Abstract
Fossil energy cost of the cultural inputs for production of dry beans (Phaseolus vulgaris L.), a cheap source of food protein, were highest for fertilization followed in declining order by crop establishment, machinery, irrigation, harvesting, weed control, insect control, transportation, and disease control. The average energy requirement was 20.6 GJ ha−1 and 10.4 MJ kg−1 of beans produced, and protein energy output/energy input equalled 0.38. Dry beans grown in California compared favorably in protein produced per hectare and fossil‐energy use efficiency with other crops widely grown in the USA.
