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 ...

High rhizospheric ammonium levels in Sorghum halepense (johnsongrass) suggests nitrification inhibition potential

Agricultural &Environmental Letters, Volume 9, Issue 2, December 2024.
Sorghum halepense (johnsongrass) has the ability to retain high rhizospheric ammonium. This suggests potential nitrification inhibition capability of johnsongrass. Under resource competition on the roadsides, johnsongrass might have undergone adaptive evolution to retain more ammonium than in croplands, which are fertilized periodically with nutrients,
