[Forage potential of Venezuelan accessions of Centrosema pubescens]
1995
Faria M, J.
A trial was conducted on a sandy loam Alfisol in the Laberinto Zone of Zulia state, Venezuela. The trial held from August 1990 to September 1992, evaluated 10 Venezuelan accessions of Centrosema pubescens for adaptation, green dry matter (GDM), seed production, crude protein (CP), in vitro organic matter digestibility (IVOMD), growth, and pest tolerance. Centrosema pubescens CIAT 15160 had the total highest GDM production at 12.9 t/ha, followed by C. pubescens CIAT 5169 with 12.6, CIAT 5627 with 11.4 and CIAT 15133 with 11.3. Centrosema pubescens CIAT 5189, 5169, and 15160 had the highest annual pure seed production (468, 391, and 268 kg/ha, respectively). Crude protein in the dry season was 18.8 percent, whereas in the rainy season it was 21.3 percent. Inversely, IVMOD was higher during the dry season (57 percent) than in the rainy season (46.6 percent). These results indicate that C. pubescens CIAT 15160, 15133, 5627, and 5169 are the most promising accessions for the Laberinto Zone, Venezuela.
