What is the primary characteristic of the harvest index?

Amount of biomass produced

Proportion of economic yield

The primary characteristic of the harvest index is the proportion of economic yield, which refers to the portion of the total biomass that is considered economically valuable, such as grain, fruit, or other marketable products. In agronomy, the harvest index is calculated by dividing the economic yield by the total biomass produced by a crop. This measurement is crucial because it provides insights into the efficiency of a crop in converting biomass into products that can be sold or used for human consumption, allowing farmers and agronomists to evaluate and compare the productivity and profitability of different crop varieties or farming practices. A higher harvest index indicates that more of the plant's biomass is contributing to the economic yield, which is a key goal in crop production.
