Effect of the addition of Enterolobium cyclocarpum pods and Gliricidia sepium forage to Brachiaria brizantha on dry matter degradation, volatile fatty acid concentration, and in vitro methane production.

The purpose of this study was to determine the in vitro fermentation and methane (CH) production in the grass Brachiaria brizantha (B) alone or when mixed with Gliricidia sepium forage (G) and/or Enterolobium cyclocarpum pods (E). Theses substrates were incubated in the following proportions: B100 (B100%), B85E15 (B85% + E15%), B85G15 (B85% + G15%), B85GE15 (B85% + G7.5% + E7.

Biological Nitrification Inhibition (BNI): Phenotyping of a Core Germplasm Collection of the Tropical Forage Grass Under Greenhouse Conditions.

Modern intensively managed pastures that receive large external nitrogen (N) inputs account for high N losses in form of nitrate (NO ) leaching and emissions of the potent greenhouse gas nitrous oxide (NO). The natural plant capacity to shape the soil N cycle through exudation of organic compounds can be exploited to favor N retention without affecting productivity. In this study, we estimated the relationship between biological nitrification inhibition (BNI), NO emissions and plant productivity for 119 germplasm accessions of Guineagrass (), an important tropical forage crop for livestock production.
