Triticum compactum or incomplete specimen. As a general rule, if a naked wheat, wheat with round grains and irregularly broken rachis forming internodes, is uncovered in a European site, excluding all sites on the Italian or Balkan peninsulas, it should be considered a hexaploid club wheat (either "T. aestivum" or "T. compactum" ). If such wheat has short internodes it should be identified as "T. compactum". "Triticum compactum" generally flowers during the months of June and July with its seeds ripening in August and September. "Triticum compactum" is an annual plant growing to heights of approximately 0.6 meters in the summer and
Crop residue annual global amount of collectable rice straw (not total produced straw) for biofuel production was estimated about 249 million tonnes, that could approximately produce 355.78 kilotonnes of hydrogen and 11.32 million tonnes of lignin by the proposed organosolv technology and it was found that China contributes to about 32% of global potential capacity to produce biohydrogen from rice straw. Nutrients in most crop residue are not immediately available for crop use. Their release (called mineralization) occurs over a period of years. The biological processes involved in soil nutrient cycles are complex. As a rough guide, cereal straw releases about 10
