Doses E Fontes De Nitrogênio Na Produção E Composição Bromatológica Do Capim-Xaraés

Abstract: This study evaluated the effect of nitrogen sources and doses on dry matter yield and bromatological composition of xaraés grass throughout the year. The experiment was carried out at the Agronomy Faculty of Rio Verde University from October 2008 to January 2010. The experiment consisted of a randomized complete block design in a 2 x 4 factorial arrangement with measures repeated in time, and four replications. We tested two nitrogen sources (ammonium sulfate and urea) and four nitrogen levels (0, 200, 400 and… Show more

“…The best results of leaf dry matter production of the native capim-açú are in agreement with those found by Costa et al (2013), reinforcing the idea that native species have relatively lower N demand (Shivega & Aldrich-Wolfe, 2017) compared to exotic species (Oliveira et al, 2016).…”

“…Antelope grass is considered an invasive species (López Rosas et al, 2015), that may lead to future environmental problems. Pasture grasses usually are very responsive to N availability in the soil (Paiva et al, 2012;Costa et al, 2013;Gazola et al, 2019), and this response can be more evident under suitable K supply (Prajapati & Modi, 2012;Sanchês et al, 2013;Morais et al, 2016). In addition, antelope grass plant characteristics (Clayton et al, 2006) are very different from those of capimaçú (Machado et al, 2013), which may lead to differences in plant growth responses to N and K fertilization.…”

“…Currently, the diet formulation for ruminants has taken into account the amount of sulfur amino acids (mainly methionine) in diet ingredients and when necessary are added synthetically (Fagundes et al, 2018). Costa et al (2013) working with Xaraes palisadegrass also verified high efficacy for the use of ammonium sulfate, but recommend the execution of works that consider economic analysis. The effect of fertilization with 200 kg N ha -1 as ammonium sulfate split in three times in the annual ryegrass pasture for 202 days (sowing on April 14 and last evaluation on November 8, 1994) was investigated by Soares, Restle, Roso, Lupatini, and Alves Filho (2001), who reported that the average daily accumulation rate was 36.1 kg dry matter, reaching a cumulative dry matter production of 6,618 kg, whose values are close to those obtained in the present study with treatment 250.…”

“…The increase in dry matter production of Xaraé s grass in the winter season under nitrogen doses was a reflection of the last nitrogen application to occur in late March, thus demonstrating the importance of carrying out fertilization at the end of the rainy season, to minimize the effect of seasonality of forage production (Costa et al, 2013). Behavior also observed by Mello et al (2008) who noted an increase in dry matter production in the low precipitation period with the application of 20% nitrogen in the dry period of the year.…”

“…The application of nitrogen to haul at the end of the rainy season can assist ranchers in the production of quality forage in the months of low rainfall, where pasture tends to reduce the accumulation of green and dry biomass. The seasonality reduction of dry matter production according to Costa et al (2013) and Freire et al (2012) can be performed with the application of nitrogen in late summer and/or early autumn.…”
