Torres González, Alba MarinaMorton, C.M.[Molecular and morphological phylogenetic analysis of Brachiaria and Urochloa (Poaceae)]Molecular and morphological phylogenetic analysis of Brachiaria and Urochloa (Poaceae)

Brachiaria species are widely sown on the infertile and Al-toxic soils of neotropical savannas. Breeding programs seek to combine edaphic adaptation with other traits in interspecific hybrids. Edaphic adaptation is difficult to assess because it is only manifest in pasture persistence across seve...


Wenzl, PeterArango Vélez, AdrianaChavez, Alba L.Buitrago González, M.E.Patino, GMMiles, John W.Rao, Idupulapati M.[A greenhouse method to screen brachiariagrass genotypes for aluminum resistance and root vigor]A greenhouse method to screen brachiariagrass genotypes for aluminum resistance and root vigor

Aluminum‐resistant Brachiaria decumbens Stapf cv. Basilisk (signalgrass) and closely related, but less resistant Brachiaria ruziziensis Germain & Evrard cv. Common (ruzigrass) both accumulated high concentrations of aluminum (Al) in roots. Approximately two thirds of the total Al was complexed by...

Using a simulation model as an analysis tool, the economic impact of spittlebugs in pastures of Colombia was quantified in terms of animal production. Three levels of abundance (10, 25, 50 adults/m2 ) and farm area affected (25, 50, 100%) were evaluated using data obtained in Brazil for Notozulia...


Holmann, Federico J.Peck, DC[Economic damage caused by spittlebugs (Homoptera: Cercopidae) in Colombia: A first approximation of impact on animal production in Brachiaria decumbens pastures]Economic damage caused by spittlebugs (Homoptera: Cercopidae) in Colombia: A first approximation of impact on animal production in Brachiaria decumbens pastures

This paper describes a Tropical Pasture Simulator. This is a simple mechanistic model representing the growth of vegetative tropical pastures under rotational or continuous grazing with responses to N fertiliser, temperature and irradiance that can be used as a tool to study management options fo...


Herrero, Mario T.Fawcett, R.H.Silveira, V.Busqué, J.Bernués, A.Dent, J.B.[Modelling the growth and utilisation of kikuyu grass (Pennisetum clandestinum) under grazing. 1. Model definition and parameterisation]Modelling the growth and utilisation of kikuyu grass (Pennisetum clandestinum) under grazing. 1. Model definition and parameterisation

The objective of this study was to predict the in vitro gas production and the estimated metabolisable energy (ME), crude protein (CP) and neutral detergent fibre (NDF) concentrations of kikuyu grass (Pennisetum clandestinum) by near infrared reflectance spectroscopy (NIRS). A total of 288 sample...

In a field study in Kenya, 55 plots in a Pennisetum purpureum sward were cut in rotation to give a 55-d regrowth cycle. After cutting, each plot was weeded and given 6.3 kg N + 4.5 kg P/ha. The daily DM production varied from 25 (dry season) to 178 kg DM/ha (rainy season). The mean DM yield after...

A grazing trial was carried out in the Eastern Plains of Colombia to compare legume selection by transiently grazed oesophageal-fistulated steers and non-fistulated steers permanently grazing pastures. The 6 pasture types investigated were Arachis pintoi-Brachiaria humidicola mixtures which diffe...
