Lately sweet sorghum (S) has attracted great interest as an alternative feedstock for biofuel production due to its high yielding potential and better adaptation to drought than maize (M). However, little is known about the response of newly developed sweet sorghum genotypes to water deficits, especially at the root level and its water uptake patterns. The(More)
Uncertainty in predictions of long-term yields of perennial grasses makes business plans untenable in the short run. Long-term data across varied environments, including marginal lands, will help in preventing uncertainty while providing farmers and entrepreneurs with sound information to estimate reliable and affordable strategies on what, where, and how(More)
High and stable biomass yields for long periods (15–20 years) are indispensable for the successful establishment of a well-developed bioenergy sector. However, the effects of management practices, particularly nitrogen fertilization, on productivity and soil organic carbon (SOC) are difficult to understand, especially when considering that continuous(More)
A major constrain for sweet sorghum (Sorghum bicolor L. Moench) establishment as a reliable biofuel feedstock is the fast biomass degradation immediately after harvest due the high content of soluble sugars and their rapid fermentation that considerably decrease the actual ethanol yield. Such a drawback does not allow storing of sorghum for a reasonable(More)
