Características agronômicas e viabilidade do tifton-85 (Cynodon spp) irrigado num sistema de produção de leite

Abstract: O experimento foi conduzido no CTCO/FESR da EPAMIG para avaliar a economicidade da irrigação da pastagem de Tifton-85 e características agronômicas do relvado. Foram utilizadas duas áreas de 3,54 ha (com e sem irrigação), divididas em oito piquetes de 4.430 m² manejados em sistema de lotação rotacionada. Estas áreas foram adubadas com 200 kg de N/ha, parcelados durante o verão. A comparação foi feita com base no teste de hipótese em amostras pariadas. A irrigação promoveu aumento na produção de folhas verdes, … Show more

“…The comparison of productions obtained in this study with those of others is not valid by the method of forage removal through grazing, but leaf blade dry forage mass reached high annual availability, of 25,872 kg/ha in xaraes grass, against 21,098 kg/ha in tifton 85 grass, at the 11 evaluations. Average per harvest similar to this experiment was obtained by Balieiro Neto et al (2007) with tifton 85 grass irrigated under grazing with rotational stocking, who obtained average 2,249 kg/ha green leaf dry forage mass (blade + leaf sheath) at pre-grazing in eight assessments during the seasons of summer/fall/winter. Aguiar et al (2006), on tifton 85 pasture irrigated under grazing, obtained average pre and post-grazing forage masses of 7,948 and 3,386 kg/ha, respectively.…”

“…Despite their contrasting morphological characteristics, both species were included in this study for meeting two premises: Xaraes grass had been recently launched by EMBRAPA, in 2003 (Valle et al, 2004) and stood out in an assay under irrigation (Alencar et al, 2009a) involving tropical grasses; tifton 85 grass was tested in several experiments under irrigation (Marcelino et al, 2003;Aguiar et al, 2006;Balieiro Neto et al, 2007) and could serve as a reference species due to the greater number of studies.…”

“…Nas regiões Centro-Sul, onde há queda significativa da produção de forragem durante o inverno (Balieiro Neto et al, 2007), a irrigação, apesar de não ser capaz de alterar a situação, pode ser utilizada para diminuir a estacionalidade (Benedetti et al, 2000;Rassini, 2004).…”

“…O uso da irrigação em pastagens Tifton 85 por produtores baseia-se na experiência empírica, devido à falta de bases científi cas (BALIEIRO NETO et al, 2007). Entretanto, informações, como as exigências nutricionais para estabelecimento e manutenção em áreas com irrigação, são ainda pouco conhecidas (ALENCAR et al, 2010).…”
