Perennial Staple Crops: Yields, Distribution, and Nutrition in the Global Food System

Frontiers in Sustainable Food Systems, 2020
Staple crops, which have large amounts of carbohydrates, proteins, and/or fats, provide the bulk of calories in people's diets. Perennial plants, which can be productive for many years without the need for replanting, can produce staple foods and ...

Can the Wild Perennial, Rhizomatous Rice Species Oryza longistaminata be a Candidate for De Novo Domestication?

Rice, 2023
As climate change intensifies, the development of resilient rice that can tolerate abiotic stresses is urgently needed. In nature, many wild plants have evolved a variety of mechanisms to protect themselves from environmental stresses.

Influence of adjacent crop type on occurrence of California ground squirrels on levees in the Sacramento Valley, California

Wildlife Society Bulletin, 2014
In the Sacramento Valley in California, USA, burrowing activities of California ground squirrels (Otospermophilus beecheyi) on levees pose a threat to human safety and property by potentially compromising levee integrity during a flood event.

The Effects of Different Crop Rotations on the Quality of Saline Soils in the Yinbei Plain

Agronomy
Rice cultivation has the ability to ameliorate saline soils, but this monoculture pattern can lead to negative plant–soil feedback. In a previous study, we investigated the effects of long-term rice cultivation on saline soil chemistry, salt ions, root ...

Adoption of inland valley farming and rice production practices: Evidence from smallholder farmers in Côte d’Ivoire and Ghana

Agricultural and Resource Economics Review
Inland valley wetlands in West African countries are considered to hold immense potential for rice-based production systems. Policies to increase rice production in inland valleys have until now not lived up to expectations.

Evaluating nitrogen response and nitrogen-use-efficiency in perennial rice

European Journal of Agronomy
Problem or Context Transplanting of rice is under pressure due to labour shortage, especially where rice is double cropped. This has renewed interest in ratooning, with perennial rice providing additional opportunities. Objective or Research Question This paper examines the response of perennial rice PR25 to N management over regrowth cycles ...
