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
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
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 ...

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

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).
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.

Sward structure and nutritive value of tanzania guineagrass subjected to rotational stocking managements [PDF]
The objective of this work was to evaluate the sward structure and nutritive value of Panicum maximum Jacq. cv. Tanzânia subjected to rotational stocking managements characterised by a common pre-grazing condition of 95% canopy light interception (LI) and two post-grazing residues, 25 and 50 cm.
