COMPOSIÇÃO BROMATOLÓGICA DO CONSÓRCIO DE MILHO, CAPIM E GUANDU NA RECUPERAÇÃO DE PASTAGEM DEGRADADA

Abstract

The work aimed to evaluate the spatial variability of the bromatological composition of corn silages intercropped with tamani grass (Panicum maximum cv. BRS Tamani) and pigeon pea. ‘Super N’ (Cajanus cajan) cultivated at diferente sowing times, aiming at the recovery of degraded pastura areas. The experimente was carried out at the Teaching, Research and Extension Unit (UEPE) Boa Esperança, in the city of Iporá – Goiás. The experimental design used was completely randomized, with treatments consisting of three sowing times (9 and 30 November and 19 December and 19 December 2017); twelve areas (paddocks) evaluate, and two replications, totaling 24 plots. Hybrid corn cv. ‘AG 1051’ (Zea mays), tamani grass and pigeon pea. ‘Super N’ in the same operation, wih the aid of a seeder with a third seed box, in three diferente seasons (9 and 30 November and 19 December 2017). The levels of calcium (Ca), phosphorus (P), crude protein (PB), crude fiber (FB), ether extract (EE), mineral matter (MM), total digestible nutrients (NDT), acid detergent fiber were determined (FDA), neutral detergent fiber (NDF). The consortium of corn, tamani grass and pigeon seeded in mid-December provided a better nutritional quality silage, with lower NDF, FDA content and higher PB and NDT content. Based on the information that there is spatial variability, with more or less productive areas, the individualized look of each productive area is required.
