AGRONOMIC EVALUATION OF FORAGES SORGHUM (Sorghum vulgare) AND MILLO GENOTYPES FOR FEEDING BOVINE IN THE SINÚ VALLEY
Journal Title: Revista MVZ Cordoba - Year 2007, Vol 12, Issue 2
Abstract
Objective. To evaluate seven millo and five sorghum genotypes to determine forage yield and to use it in feeding bovine in Sinú valley, Colombia. Materials and methods. Sorghum (Sorghum vulgare) and millo seeds were hybrid materials and commercial type varieties. A design of complete blocks at random was used with four repetitions for millo and three for sorghum. Results. Regarding vigor the genotypes that better behavior presented were the round Cuba and white long panicle for millo and LC 603, P-8239 and DR-1125 for sorghum. The millos that showed bigger senescence was the high cuarentano, the cane and the white long panicle; in sorghum those of more senescence were P-8239, LC 603 and 74 CO. Biggest production of green forage and dry matter were presented by millo, Batea Cuba, Round Cuba and white long panicle genotypes, for sorghum were Blanco Creole and DR-1125. The biggest yield grain was of batea Cuba and cane genotypes in millo, and in sorghum were DR-1125 and LC 603. As materials of good behavior inside all those evaluated were selected the Batea Cuba, Round Cuba, and white long panicle in millo and Blanco Creole and DR-1125 in sorghum. Conclusions. The millo genotypes that better behavior presented were in its order for yield (ton/ha): batea Cuba, round Cuba and white long panicle (ton/ha), being obtained a bigger capacity of animal load. The genotypes of better behavior of sorghum were Blanco Creole and DR-1125.
