ABSTRACT:The pasture irrigation has expanded, mostly in small areas in order to boost the production system, along with the use of soil improvement techniques and high-productivity grasses. Thus, this study, carried out on a small dairy farm property, aimed to evaluate the productivity, botanical composition and nutritive value of Tifton 85 with different nitrogen (N) doses, in the presence and absence of irrigation. The experimental design was a randomized block in a split-plot design with four replications, plots Non-irrigated and Irrigated. The subplots consisted of nitrogen doses: 25 kg ha -1 cycle -1 of N, 50 kg ha -1 cycle -1 of N, 75 kg ha -1 cycle -1 of N and 100 kg ha -1 cycle -1 of N. The irrigation increased the productivity in an average of 3,626.5 kg ha -1 cycle -1 , with higher leaf stem ratio of 1.3, increasing the crude protein content of the pasture. The productivity responded quadratically to nitrogen fertilization with increases up to 84 kg N ha -1 cycle -1 with slight linear decrease of dead matter. There were linear increments of crude protein and digestibility "in vitro" of dry matter in function of applied nitrogen.

“…Os dados experimentais foram submetidos à análise de variância (p ≤ 0,05) e quando significativas as médias foram comparadas pelo Teste de Tukey (p ≤ 0,05) com a utilização do programa estátistico Assistat 7.6 beta (Silva & Azevedo, 2009 (Fonseca et al, 2007;Nogueira et al, 2013;Teixeira et al, 2013) porém há uma amplitude de resultados em condição de sobressemeadura.

“…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).…”

O trabalho foi conduzido no período de abril a novembro de 2012, em uma propriedade de produção leiteira, no município de Mariluz, Região Noroeste do Paraná, com o objetivo de avaliar a produtividade, a composição botânica e o valor nutritivo do capim Tifton 85 sobressemeado com aveia, na presença e ausência de irrigação. O delineamento experimental foi de blocos casualizados em parcelas sub-subdivididas, com 4 repetições. As parcelas foram sem e com irrigação. As subparcelas foram constituídas de sobressemeaduras de aveia: FMS 2, IAPAR 61, IPR 126 e um tratamento com o Tifton 85 exclusivo. Os ciclos de coleta compuseram as sub-subparcelas. A irrigação incrementou a produtividade da pastagem com média de 2760,4 kg ha-1 ciclo-1, com a maior relação folha/colmo de 2,8, aumentando a digestibilidade da matéria seca. Os valores de proteína bruta foram maiores no irrigado e na média do irrigado e não irrigado, diminuíram ao longo dos ciclos de coleta de 18,6 para 13,6%. As maiores produtividades foram obtidas por meio das sobressemeaduras das aveias FMS 2 e IPR 126. O Tifton 85 exclusivo apresentou o maior valor de fibra em detergente neutro e o menor valor de digestibilidade.

ABSTRACT:The use of irrigation and fertilization with swine wastewater (SW) can be an excellent alternative to increase the production and pasture quality. The work was carried out from October 2013 to September 2014 in Dourados -MS, and aimed to evaluate the production and nutritional quality of Tifton 85 grass (Cynodon spp.) under different rates of SW, in the presence and absence of irrigation. The experiment design was randomized blocks in a split plot scheme, with irrigation and without irrigation in the plots, and four rates of SS in the subplots: 75, 150, 225 and 300 m 3 ha -1 cut -1 , with four replications. There was a significant effect of irrigation and SS rates on Total dry matter, reaching 41.4 Mg ha -1 y -1 with the highest dose tested and associated with the use of irrigation. Irrigation also provided higher levels of crude protein, increasing with linear adjustment to SS rates, reaching 17.9 % in the annual average.The neutral detergent fiber and the acid detergent fiber presented lower irrigation results and decreased linearly at the rates of SS, reaching 65.40 and 32.55% in the annual average, respectively. It was observed an inverse behavior of the "in vitro" digestibility of dry matter, which was higher under irrigation, reaching 69.5% in the annual average and presenting linear growth for the SS rates.KEYWORDS: organic fertilization, botanical composition, dry matter production, forage quality, sprinkler irrigation.
