- chrisco255 6y agoCrop yield is how much food you harvest per unit of land. It's the definition of productivity for farming. The amount of arable soil is the chief constraint on production.
- realreality 6y ago> The research measured productivity by inputs – such as labor, fertilizer and equipment – and the output in food they produce When you highlight "yield", you're only counting the outputs, not all of the inputs that this study apparently models.
- gumby 6y agoProductivity is output divided by input. So in farming it can be yield divided by labor (labor productivity), yield divided by soil addenda (e.g. fertilizer), yield in dollars divided by all costs of production, etc. Sometimes factor productivity will have a specific name. For example capital efficiency is the productivity of capital (output divided by cap ex) which, due to the very nature of capex, is usually used to find a change due to investment. The productivity of energy use, typically measured on a whole economy basis, is called “energy intensity” (gdp/GW) though some industries are called “energy intensive”
