harv_idx

Harvest index target specified at harvest

This variable will force the ratio of yield to total above-ground biomass to the specified value. If biomass is cut and removed (e.g., in hay cuttings), harv_idx must be used to specify the amount of biomass cut. For grain harvest, the harvest index in the plant growth database (plants.plt) is used instead of harv_idx, which assumes that only the seed is being harvested.
