On a calendar time basis, relative biomass growth curve became steeper at higher latitudes, indicating a shorter growing season, a narrower harvesting window, and a greater biomass yield penalty for early season harvest.
As the demand for bioenergy and bioproducts continues to rise, shrub willow will be a significant source of woody biomass, because of its fast growth, ease of cultivation, flexible harvesting window, and suitable biomass characteristics for conversion.
Keep a careful eye on grain development and bird activity, as the harvesting window can be short between the ripening of the grain and the appearance of large bird flocks.
Since harvest windows differ across species, gasification fermentation technology would enable the use of specialized harvest and collection machinery throughout many months and reduce the fixed costs of harvest machinery per unit of feedstock.
Thus, to be prepared for any of these possibilities, we undertook to determine the optimal tissue harvest windows for all of the species and reproductive tissues that we might be able to obtain.
Based on the assumptions used in this study for Oklahoma conditions, a switchgrass system with a nine-month harvest window can deliver baled biomass at a lower cost than a forage sorghum system with a five-month harvest window.
The result is an inexpensive, strong, stable, view quality-preserving solar energy-harvesting window that has no close competition.
Forage sorghum has a narrower harvest window, requires more time for field drying prior to safe baling and, as a consequence, requires significantly more harvest machines.
Fruit were harvested in the optimum harvest window based on the ethylene and starch tests, and stored in a cold room at 2 °C in a normal atmosphere for 4 months.
Whilst still theoretically within the commercial harvest window, it is unlikely that growers would wait this long to harvest a crop, as the demand for rocket is so high.
