Systems Level Regulation of Rhythmic Growth Rate and Biomass Accumulation in Grasses

Description: Several breakthroughs have been recently made in our understanding of plant growth and biomass accumulation. It was found that plant growth is rhythmically controlled throughout the day by the circadian clock through a complex interplay of light and phytohormone signaling pathways. While plants such as the C4 energy crop sorghum (Sorghum bicolor (L.) Moench) and possibly the C3 grass (Brachypodium distachyon) also exhibit daily rhythms in growth rate, the molecular details of its regulation rem… more

EFFECT OF MECHANICAL CONDITIONING ON THIN-LAYER DRYING OF ENERGY SORGHUM (Sorghum bicolor (L.) Moench)

Description: Cellulosic energy varieties of Sorghum bicolor (L.) Moench show promise as a bioenergy feedstock, however, high moisture content at the time of harvest results in unacceptable levels of degradation when stored in aerobic conditions. To safely store sorghum biomass for extended periods in baled format, the material must be dried to inhibit microbial growth. One possible solution is allowing the material to dry under natural in-field conditions. This study examines the differences in thin-layer d… more

Optimization of Preprocessing and Densification of Sorghum Stover at Full-scale Operation

Description: Transportation costs can be a prohibitive step in bringing biomass to a preprocessing location or biofuel refinery. One alternative to transporting biomass in baled or loose format to a preprocessing location, is to utilize a mobile preprocessing system that can be relocated to various locations where biomass is stored, preprocess and densify the biomass, then ship it to the refinery as needed. The Idaho National Laboratory has a full scale 'Process Demonstration Unit' PDU which includes a stag… more

Review of Sorghum Production Practices: Applications for Bioenergy

Description: Sorghum has great potential as an annual energy crop. While primarily grown for its grain, sorghum can also be grown for animal feed and sugar. Sorghum is morphologically diverse, with grain sorghum being of relatively short stature and grown for grain, while forage and sweet sorghums are tall and grown primarily for their biomass. Under water-limited conditions sorghum is reliably more productive than corn. While a relatively minor crop in the United States (about 2% of planted cropland), sorg… more

Global crop yield losses from recent warming

Description: Global yields of the world-s six most widely grown crops--wheat, rice, maize, soybeans, barley, sorghum--have increased since 1961. Year-to-year variations in growing season minimum temperature, maximum temperature, and precipitation explain 30% or more of the variations in yield. Since 1991, climate trends have significantly decreased yield trends in all crops but rice, leading to foregone production since 1981 of about 12 million tons per year of wheat or maize, representing an annual economi… more

Evaluation of herbacceous biomass crops in the northern Great Plains. Final report

Description: Herbaceous lignocellulose crops are a potential renewable feedstock for biochemical conversion systems second in size to wood products. Several herbaceous crops are utilized as forage crops in the northern Great Plains, but forage quality considerations usually dictates a early harvest. Biomass cropping does not have this constraint; therefore, little information was available on herbaceous crops utilized as energy crops prior to this project. Our primary objectives were to evaluate the biomass… more

Selection of herbaceous energy crops for the western corn belt

Description: The ultimate economic feasibility of biomass depends on its cost of production and on the cost of competing fuels. The purpose of this research project is to evaluate the production costs of several combinations of species and management systems for producing herbaceous biomass for energy use in Iowa. Herbaceous biomass production systems have costs similar to other crop production systems, such as corn, soybean, and forages. Thus, the factors influencing the costs of producing dedicated biomas… more

Selection of herbaceous energy crops for the western corn belt. Final report Part 1: Agronomic aspects, March 1, 1988--November 30, 1993

Description: The relative high cost of energy derived from biomass is a major deterrent to greater use of biomass for energy production One of the most important methods of lowering the cost of dedicated biomass production is to increase the yield per unit of land area so that fixed costs can be applied to more tons of forage. For this study, the authors selected grass and legume crops with potential for high biomass yields and those that offer protection from soil erosion. The research reported here was co… more
