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

Grass 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

GCB 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 ...

Morphogenetic and structural characteristics of guinea grass pastures submitted to three frequencies and two defoliation severities. [PDF]

, 2011
It was evaluated the morphogenic and structural characteristics of guinea grass under rotational at three grazing intervals and two defoliation intensities. Grazing intervals corresponded to the time needed by the forage canopy to reach 90, 95 or 100% of

Isolation of diploid and tetraploid Sexual plants in guineagrass (Panicum maximum Jacq.)

Japanese Journal of Breeding, 1979
Sexually leproduclng plants (sexual plants) of guineagrass were screened by progeny tests for progressing cross breeding in this apomictic species. Two hundreds and thirty four plants of 86 guineagrass accessions were self-pollinated by bagging and/or open-pollinated.
