Nitrogen fertilization strategies for xaraes and tifton 85 grasses irrigated in the dry season

Abstract: -An experiment was carried out to assess rates and nitrogen fertilization strategies on the forage yield using irrigation to supply the water deficit during the dry season. The grasses Cynodon spp cv. tifton 85 and Brachiaria brizantha cv. Xaraés were cultivated with nitrogen (N) at levels of 200 and 400 kg/ha according to strategies: 1) half dose applied during the rainy season (RS) and half during the dry season (DS); 2) 1/3 during the RS and 2/3 during the DS; 3) 2/3 during the RS and 1/3 during the DS; 4) … Show more

“…In the seventh cycle, with no precipitation in the first 20 days and its concentration at the end, there was no production in the non-irrigated plots. NOGUEIRA et al, 2013;TEIXEIRA et al, 2013;QUEIROZ et al, 2012;OLIVEIRA et al, 2011;FONSECA et al, 2007). The non-irrigated productivity is compatible with the averages found from 55 to 83 kg ha -1 day -1 (FAGUNDES et al, 2012;AGUIAR et al, 2010).…”

“…In relation to the dry matter yield of Tifton 85, researches indicate values up to 55 kg ha -1 d -1 (DE MATOS et al, 2013, as well as values between 55 and 83 kg ha -1 d -1 (FAGUNDES et al, 2012;AGUIAR et al, 2010;MARSALIS et al, Productivity and nutritive value of Tifton 85 in summer, with and without irrigation under different nitrogen doses NOGUEIRA et al, 2013;TEIXEIRA et al, 2013;QUEIROZ et al, 2012;BOW & MUIR, 2010;FONSECA et al, 2007), and it can reach more than 165 kg ha -1 d -1 (AGUIAR et al, 2006 Thus, the aim of this study was to evaluate the productivity, botanical composition and bromatological composition of the Tifton 85 grass during the months of November to May, with different nitrogen doses in the absence and presence of irrigation.…”

“…Com o uso da irrigação as produtividades ultrapassam 96 kg ha -1 d -1 (Fonseca et al, 2007;Queiroz et al, 2012;Nogueira et al, 2013;Teixeira et al, 2013) podendo chegar a mais de 165 kg ha -1 d -1 (Aguiar et al, 2006). Além da irrigação a sobressemeadura de aveia vem sendo utilizada como medida prática e econômica que incrementa a produtividade e melhora a distribuição estacional das pastagens no período de entressafra (Furlan et al, 2005;Moreira et al, 2006b); no entanto, a sobressemeadura de aveia em capins do gênero Cynodon nem sempre incrementa, de maneira expressiva, a produtividade de matéria seca da forragem (Moreira et al, 2006a;Rocha et al, 2007).…”
