Soil Nitrogen Dynamics and Transformation Under No-Tillage Perennial Rice Farming Systems

Agriculture
Annual rice growing lands are mainly threatened by soil loss. High-yielding perennial rice cultivars with great socioeconomic values are developed to stabilize fragile rice farms.

Abiotic and biotic context dependency of perennial crop yield.

PLoS ONE, 2020
Perennial crops in agricultural systems can increase sustainability and the magnitude of ecosystem services, but yield may depend upon biotic context, including soil mutualists, pathogens and cropping diversity.

Adapting perennial grain and oilseed crops for climate resiliency

Crop Science, 2023
AbstractClimate change is threatening the status quo of agricultural production globally. Perennial cropping systems could be a useful strategy to adapt agriculture to a changing climate. Current and future perennial row crop systems have many and varied applications and these systems can respond differently than annuals to agricultural challenges ...

Evaluation of fall‐seeded cover crops for grassland nesting waterfowl in eastern South Dakota

Wildlife Society Bulletin, EarlyView., 2023
Cover crops are experiencing a revival among Midwestern farmers, and we assessed their attractiveness and safety for nesting ducks in South Dakota. Nest success was markedly lower in cover crops than in perennial cover during both years of our study, including 2019 which was a best‐case scenario for cover crops, with extremely wet conditions delaying ...

Increased Food and Ecosystem Security via Perennial Grains

Science, 2010
Perennial grains hold promise, especially for marginal landscapes or with limited resources where annual versions struggle.

Review and analysis of technologies for harvesting perennial grain crops

IOP Conference Series: Earth and Environmental Science, 2021
Abstract In agriculture, according to the data of the statistical collection, the production of grain crops occupies a large part. At the moment, much attention is paid to the study of perennial crops such as Thinopyrum intermedium and Trititrigia cziczinii Tsvelev.

Brachypodium sylvaticum, a model for perennial grasses: transformation and inbred line development. [PDF]

PLoS ONE, 2013
Perennial species offer significant advantages as crops including reduced soil erosion, lower energy inputs after the first year, deeper root systems that access more soil moisture, and decreased fertilizer inputs due to the remobilization of nutrients ...

Rhizodeposition Drives One Third of Belowground Carbon Input in Agroecosystems

Advanced Science, EarlyView.
This study quantifies photosynthesized C allocation in the plant–soil system across six crop types: barley, wheat, maize, rice, legumes and grasses. It reports C partitioning into shoot respiration, shoot‐C, root‐C, net rhizodeposition and root‐derived CO2, providing standardized percentage averages and GPP‐derived absolute values as a robust baseline ...

Integrating Perennial Groundcover in Corn and Soybean Acres: Impacts on U.S. Agriculture

Applied Economic Perspectives and Policy, EarlyView.
ABSTRACT Sustainable agricultural practices such as cover cropping can improve soil health, water quality, and carbon sequestration, yet U.S. adoption remains limited due to economic and operational barriers. We evaluate market and economic impacts of integrating perennial groundcover into U.S.

QTL for seed shattering and threshability in intermediate wheatgrass align closely with well‐studied orthologs from wheat, barley, and rice

The Plant Genome, 2021
Perennial grain crops have the potential to improve agricultural sustainability but few existing species produce sufficient grain yield to be economically viable. The outcrossing, allohexaploid, and perennial forage species intermediate wheatgrass (IWG) [
