NOVELTY - Increasing harvest time flexibility for sugar extraction from sorghum plants, involves extracting sugar from photoperiod sensitive sweet sorghum plants harvested prior to initiation of floral development.    USE - For increasing harvest time flexibility for sugar extraction from sorghum plants, and for making biofuel (claimed).    ADVANTAGE - The sweet sorghum plants has increased photoperiod sensitivity. In addition, the photoperiod sensitive sweet sorghum plants can exhibit commercially acceptable levels of sugar accumulation even when flowering is delayed or does not occur. The photoperiod sensitive sorghum plant has their reproductive maturation (e.g. initiation of floral development) triggered by day length as opposed to planting time. The method provides flexibility to milling operators (e.g. sugar extraction facilities). The photoperiod sensitive sweet sorghum plants can be harvested without cutting the head. Having the ability to harvest photoperiod sensitive sweet sorghum plants without cutting the head can help reduce stalk loss and ergot infection. In addition, harvesting photoperiod sensitive sweet sorghum plants for sugar extraction at a point prior to floral development can help to reduce lodging.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following:    (1) obtaining sorghum plants for sugar extraction, involving (a) planting seeds to grow photoperiod sensitive sweet sorghum plants in a field, and (b) harvesting the photoperiod sensitive sweet sorghum plants for sugar extraction prior to initiation of floral development, where the photoperiod sensitive sorghum plants have an average BRIX value that is greater than 10 percent at harvest time;    (2) expanding a sorghum milling window of a sugar mill, involving providing the mill with photoperiod sensitive sweet sorghum plants harvested for sugar extraction before initiation of floral development;    (3) operating a sugar mill, involving receiving multiple different deliveries of harvested sorghum plants for sugar extraction, where the multiple different deliveries are more than two days apart, where the sorghum plants of at least one of the multiple different deliveries comprise photoperiod sensitive sweet sorghum plants harvested prior to initiation of floral development;    (4) making a biofuel, involving planting seeds in at least one field to obtain at least 10 acres of photoperiod sensitive sweet sorghum plants, harvesting sorghum biomass from the photoperiod sensitive sweet sorghum plants prior to initiation of floral development to obtain harvested sorghum biomass, extracting sorghum stem juice from the harvested sorghum biomass to obtain extracted stem juice comprising sugar, using the sugar of the extracted stem juice in a fermentation reaction to produce a fermentation product comprising a biofuel, and isolating the biofuel from the fermentation product to obtain a composition comprising the biofuel; and    (5) transporting a biofuel, comprising offloading a bio fuel from a floating vessel to a terrestrial facility, involving planting seeds in at least one field to obtain at least 10 acres of photoperiod sensitive sweet sorghum plants, harvesting sorghum biomass from the photoperiod sensitive sweet sorghum plants prior to initiation of floral development to obtain harvested sorghum biomass, extracting sorghum stem juice from the harvested sorghum biomass to obtain extracted stem juice comprising sugar, using the sugar of the extracted stem juice in a fermentation reaction to produce a fermentation product comprising a biofuel; and isolating the biofuel from the fermentation product to obtain a composition comprising the biofuel.
