Three carbon methabolism pathway in photosynthesis is the main aspect to determine the best adaptation of grasses to provide high quantity of biomass in one year in temperate climates. Winter grasses are typical in forage management since the earlier stages of agricultural development in the planet. From forages to grain cereals, whole plant cuttings have been present in the rural sectors of most European and Northamerican countries.

 

The biomass obtained in bales is easy to harvest and handle and can be used for pulp or energy in several transformation to energy available. Today triticale, rye and many other annual winter grasses can produce more than 14 oven dried tonnes per hectare to produce electricity in real power plants like those 25MW power plants  existing and operating with straw in many countries therefore providing green energy to the grid and replacing fossil energy; possible savings up to 90% when replacing natural gas electricity have been registered in EU. Harvest optimum moment is often considered before grain maturity using physiological scales. When producing biomas for biogas digesters, many management techniques have to change for an optimization. Moisture contents might allow logistic systems using biomass with higher levels of moisture compared to systems to produce bales (lower moisture levels than 15%). Yields can be higher producing many cuttings per year obtaining more than 40 oven dried tonnes per year under certain conditions.
