I: | New cultivars produced by plant breeding are first evaluated in research fields and their performance is recorded under ideal fertiliser application, irrigation, and other crop management practices. |
II: | After evaluation in research fields, the new cultivars are tested in farmers’ fields for at least three growing seasons at several locations in the country. |

I: | SCP is commonly grown on agricultural waste products, and as such inherits the ecological footprint and water footprint of industrial agriculture. |
II: | Microorganisms usually have a much higher protein content of 30–70% in the dry mass than vegetables or grains. |
