  1. Abstract,bioRxiv, 2019 Herbaceous perennial species are receiving increased attention for their potential to provide both edible products and ecosystem services in agricultural systems. Many legumes (Fabaceae Lindl.) are of special interest due to nitrogen fixation carried out by bacteria in...
  2. Farmers and environmentalists alike seek a crop that is economically and environmentally sound. A new crop ‘perennial wheat’ may have that potential. Perennial wheat is a crop that has been under development for almost 70 years, across the globe. It is currently being trialed on farmers’ organic...
  3. Abstract, Frontiers in Plant Science, 2020 Perennial grains could simultaneously provide food for humans and a host of ecosystem services, including reduced erosion, minimized nitrate leaching, and increased carbon capture. Yet most of the world’s food and feed is supplied by annual grains....
  4. Abstract, PlosONE, 2020 The use of perennial crop species in agricultural systems may increase ecosystem services and sustainability. Because soil microbial communities play a major role in many processes on which ecosystem services and sustainability depend, characterization of soil community...
  5. Abstract, Springer Link, 2020 Perennial grain crops are gaining increased attention from researchers as one possible solution to agriculture’s many sustainability challenges. In the Sub-Saharan African context, perennial varieties of crops such as sorghum, rice, and pigeon pea have potential to...
  6. Perennial plants do not have to be reseeded or replanted every year, so they do not require annual plowing or herbicide applications to establish. Annual wheat on the left, and Kernza on the right. Perennial crops are robust; they protect soil from erosion and improve soil structure. They...

  8. The Land Institute is a 501(c)(3) non-profit organization based in Salina, Kansas, that was founded in 1976. The Land Institute’s work, led by ateam of plant breeders and ecologistsinmultiple partnerships worldwide, is focused on developing perennial grains, pulses and oilseed bearing plants to...
  9. Pigeon pea (Cajanus cajan) is a tropical legume native to South Asia. Its high protein content and adaptability to arid environments have made it an important food crop across sub-Saharan Africa. Pigeon pea is a genetically diverse crop with several varieties that differ in time to maturity and...
  10. Kernzagrain is harvested from intermediate wheatgrass (Thinopyrum intermedium). This (cousin) of annual wheat has been grown throughout the USA to provide fodder for livestock. Now intermediate wheatgrass is being domesticated as a grain for human food. Intermediate wheatgrass can be grown as a “...
  11. European Journal of Agronomy122:126186, January 2021, DOI:10.1016/j.eja.2020.126186 Perennial grain has been proposed to provide an effective means of ensuring both food and ecological security. The newly released cultivar of perennial rice 23 (PR23) represents a new rice production system that...
