Perennial Grain and Oilseed Crops

Annual Review of Plant Biology, 2016
Historically, agroecosystems have been designed to produce food. Modern societies now demand more from food systems—not only food, fuel, and fiber, but also a variety of ecosystem services. And although today's farming practices are producing unprecedented yields, they are also contributing to ecosystem problems such as soil erosion, greenhouse gas ...

Annual vs. perennial grain production

Agriculture, Ecosystems and Environment, 2012
Abstract Annual grain crops are planted on about 70% of the world's cropland and provide 80% of the world's food. Currently annual grains dominate grain production. Perennial grains offer many important opportunities to produce grains in a more environmentally, economically, and energetically sound manner.

Progress in breeding perennial grains

Crop & Pasture Science, 2010
Annual cereal, legume and oilseed crops remain staples of the global food supply. Because most annual crops have less extensive, shorter-lived root systems than do perennial species, with a correspondingly lower capacity to manage nutrients and water, annual cropping systems tend to suffer higher levels of soil erosion and generate greater water ...

Perennial Grains – An Ecology of New Crops

Interdisciplinary Science Reviews, 1986
AbstractAbout 90% of human food in the world comes from only 15 crops. New crops are needed to improve agricultural ecology because of the risks of relying on so few crops. Increased cultivation of perennial grains, adapted to the temperate region, would reduce fuel inputs for tillage and would help control the world's most serious environmental ...

Grain Yields of Perennial Grain Crops in Pure and Mixed Stands

Journal of Agronomy and Crop Science, 2002
AbstractPerennial grain crops were examined in pure stands and in various mixtures for their grain yield potential in, and suitability for, low‐input systems on marginal land. The investigation was based on field experiments conducted at two sites characterized by marginal environmental conditions in south‐west Germany in 1999 and 2000. The experiments

Potential of perennial cereal rye for perennial grain production in Manitoba

Canadian Journal of Plant Science, 2019
Perennial cereal rye (Secale cereale L. × Secale montanum Guss.) has been utilized for forage production and this study investigated its perennial grain production potential in Manitoba. Two seeding years at Carman, MB, showed poor winter survival and high ergot occurrence. Therefore, this species is not recommended for grain production in Manitoba.

Progress in developing perennial wheats for grain and grazing

Crop & Pasture Science, 2014
Dual-purpose cereals have been important for increasing the flexibility and profitability of mixed farming enterprises in southern Australia, providing winter feed when pasture dry matter production is low, and then recovering to produce grain. A perennial dual-purpose cereal could confer additional economic and environmental benefits.

Perennial grain development: Past efforts and potential for the future

Critical Reviews in Plant Sciences, 1990
Abstract The development of perennial grains has the potential to provide environmentally sound, economically viable alternatives for use on erodible land where annual crop production is not sustainable. The concept of perennial grain production is not new. Historically, seeds of perennial grasses have been used as grain by various human cultures.

Nitrogen Management in a Perennial Grain-Legume Intercropped System

2022
Nitrogen pollution from intensified agricultural production is a major driver of ecosystem degradation, contributing to aquatic eutrophication and global greenhouse gas emissions. Incorporating nitrogen-fixing leguminous intercrops into agricultural systems is an increasingly popular management strategy to mitigate those negative impacts.

Nipa (Distichlis palmeri): A perennial grain crop for saltwater irrigation

Journal of Arid Environments, 2012
Abstract The perennial saltgrass nipa (Distichlis palmeri, Poaceae) is endemic to northern Gulf of California tidal marshes flooded with hypersaline (38–42 g L−1) seawater. Nipa was a wild harvest staple of the Cocopah people of the Rio Colorado delta.
