Effects of Seeding Rates On Sorghum Quality As a Bionergy Feedstock.

Manipulation of agronomic management practices can affect changes in biomass composition of sorghum, and in turn affect its value as a biofuel feedstock.  Forage and sweet sorghum varieties were seeded at increasing rates from 90,000 to 200,000 seeds per hectare and managed under multiple-cut and single-cut systems.  Biomass yields were measured and energy components estimated with near infrared reflectance spectrometry (NIR).  A summary of biomass yield and quality data collected over a two-year period from multiple locations across Texas are presented.
