New version 2.51 introduced that allow for a flexible harvest and biomass removal during development of plant. Two new switch in the Plant Growth models.
Harvest Day and Harvest Range. The Harvest Day switch first and default option (Fixed Single) correspond to the previous model with only one harvest DayNo that is specified the Harvest Plant Table. New options are: Fixed Multiple Days, Estimated GSI, and Estimated LAI. The fixed Multiple Days allow the user to specify both the different years and the different days of the years that are for harvest operations. The values are to be specified in tables (Harvest Within Years and Harvest During Years) that may include any number of operations. Depending on the value assigned to the Harvest Range Switch the operations may be assigned to specific plants or all defined plants. An index that corresponds to the plant to harvest will be seen in the Tables if only one plant is to be harvest at a time.
The option Estimated GSI means that the harvest is made with the plant has reached the Growth Stage Index of 4. The option Estimated LAI means that the user can specify a LAI value that will trigger the harvest operation. The Harvest LAI value is to be specified in the Harvest Plant Table.
Note that a new auxiliary variable SimPlantYearAge allows displaying the Plant age in year units and is complementary to the SimPlantAge that is specified in days.
