Perennial Grains – An Ecology of New Crops
Interdisciplinary Science Reviews, 1986AbstractAbout 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, 2002AbstractPerennial 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, 2019Perennial 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, 2014Dual-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, 1990Abstract 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
2022Nitrogen 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, 2012Abstract 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.

Perennial grains: From moonshot to farmers' fields
Recent advancements in breeding perennial rice and the perennial grain Kernza® illustrate progress in converting an agroecology moonshot into a deeply rooted reality. In this chapter we highlight research efforts underway to advance the scientific and sociocultural development of new perennial grain crops and cropping systems.Timothy E. Crews +8 more
