Effects of nitrogen fertilizer rate on dry matter yield, nutritive values and nitrate nitrogen of Guineagrass (Panicum maximum Jacq.) extremely late cultivar “Umaku” as a summer annual grass in a warm temperate zone

open access: yesGrassland Science, Volume 72, Issue 2, Page 151-160, April 2026.
Abstract Cultivation as a summer annual grass in temperate regions of new extremely late‐maturing guineagrass cultivar “Umaku” without heading with fertilizer application entails risks of toxic nitrate nitrogen (nitrate‐N) concentration in the grass.

Genetic Diversity and Structure of Ruzigrass Germplasm Collected in Africa and Brazil

open access: yesCrop Science, Volume 55, Issue 6, Page 2736-2745, November-December 2015., 2015
ABSTRACT Ruzigrass [Urochloa ruziziensis (R. Germain & Evrard) Crins, syn. Brachiaria ruziziensis Germain & Evrard] is a tropical forage native to Africa, first introduced in Brazil in the 1960s. Ruzigrass is diploid, presents sexual reproduction, and is a model species for the generation of genomic resources in the Brachiaria genus. Brachiaria species

Degrees of sexuality in sexual plants of guineagrass by the simplified embryo sac analysis.

open access: yesJapanese Journal of Breeding, 1983
Degrees of sexuality in lowly and highly sexual plants of guineagratss which were isolated by progeny tests in the previous paper of the authors, were investigated by using the simplified embryo sac analysis, and compared with degrees of sexuality by frequency of off-type plants in progenies.

Plant Growth‐Promoting Rhizobacteria Impacting Forage Mass of Urochloa ruziziensis and Megathyrsus maximus: A Reliable New Strategy for Tropical Pastures

open access: yesGrass and Forage Science, Volume 81, Issue 1, January-March 2026.
ABSTRACT Brazil is known for its extensive livestock production in pastures, supporting the world's second‐largest herd of cattle and being the leading beef exporter. However, livestock farming in Brazil has frequently been associated with soil degradation and greenhouse gas (GHG) emissions.

Soil Phosphorus Transformations Following Forest Clearing for Pasture in the Brazilian Amazon

open access: yesSoil Science Society of America Journal, Volume 64, Issue 5, Page 1792-1804, September 2000., 2000
Phosphorus limits grass production in pastures planted on most cleared moist tropical forest, but little is known about soil P dynamics in these ecosystems. We describe changes to total P and different soil P fractions that occurred after the conversion of forest to pasture in the Brazilian Amazon State of Rond o ˆ nia.

Yield and Stability of Three Tropical Forage Grasses Cultivated as Pure or Mixed Stands

open access: yesGrass and Forage Science, Volume 80, Issue 2, April-June 2025.
ABSTRACT Multispecific pastures are considered more sustainable to animal production than monocultures. However, studies on mixtures of tropical grasses are underexplored. We aimed to assess whether a mixture of three contrasting growth strategies of perennial tropical forage grasses could outperform their respective monocultures in terms of forage ...

Nitrogen acquisition and retention pathways in sustainable perennial bioenergy grass cropping systems

open access: yesGCB Bioenergy, Volume 16, Issue 6, June 2024.
Perennial tall grasses sustain high biomass yield with minimal synthetic nitrogen (N) fertilizer, potentially by leveraging biological N fixation and nitrification inhibition. Enhancing these traits through research and breeding can further reduce their reliance on N fertilizer and thereby support more resilient and environmentally sustainable ...

A Simple and Efficient Culture of Leaflets for Plant Regeneration in Guineagrass (Panicum maximum).

open access: yesPlant Biotechnology, 2002
A simple and efficient culture for plant regeneration was established from the leaflet tissue of Panicum maximum. The vegetative leaflets were excised from terminal tillers arising at the end of stolons and cultured for callus formation on Murashige and Skoog (MS) medium supplemented with 2, 4-dichlorophenoxyacetic acid.
