“…The greatest CP contents were observed in the first cycle of E2 in the bristle oat + millet pasture (17.2%) (P<0.01), which was not significantly different from treatments E1 bristle oat + millet (16.2%) and E1 sorghum-sudangrass (16.2%), respectively. The greatest crude protein (CP) contents observed in the first evaluation were due to the bristle oat in the pastures, as also reported by Moreira et al (2006a).…”

“…The total carbohydrate content (TC , Table 3) increased in all production cycles, ranging from 55.3 to 88.0%, as a result of the botanical composition of each plant during evaluation (Moreira et al, 2006a). Higher values of TC were observed in the fifth growth period as a result of the increase in the stem fraction, and also in the cell wall content (Moreira et al, 2006b) and the decrease in the CP content (Table 1).…”

-An experiment was conducted during the 2001-2002 winter-spring-summer to determine the nitrogen and carbohydrate fractions in Tifton-85 pastures exclusively or overseeded with oats, millet and sorghum-sudangrass hybrids. The treatments were Tifton-85 overseeded with millet + bristle oat; sorghum-sudangrass + bristle oat, on 06/19/2002 and 07/02/2002, respectively; and Tifton-85 (Control). The experiment was conducted in a randomized block design with three replications. Nitrogen and carbohydrate fractions were affected by the nitrogen and total carbohydrate contents observed in the pasture overseeded at different seeding times, and by the different growth periods. The highest nitrogen fractions (A + B1) were observed in the early growth periods. Overseeding affected the forage nitrogen and carbohydrate fraction contents positively. The high solubility of both carbohydrate and protein from millet + bristle oat and bristle oat + sorghum-sudangrass mixtures indicates the quality of these forages and their potential use as an important supplement in forage systems based on tropical pastures.

“…Existem poucos trabalhos avaliando a altura ideal de rebaixamento da espécie tropical sobre a produtividade da espécie sobressemeada. Moreira et al (2006) utilizaram rebaixamento para 5 cm de altura e Rodrigues et al (2006) entre 10 e 20 cm em espécies do genêro Cynodon, porém, a influência da altura de rebaixamento sobre as plantas sobressemeadas não são mencionadas. Bertolote (2009) trabalhando com sobressemeadura de aveia em Capim Tanzânia rebaixado a 10 ou 30 cm, observou maior produção de Capim Tanzânia e produção de forragem total quando rebaixou a Tanzânia a 10 cm.…”

ResumoO objetivo do trabalho foi avaliar a sobressemeadura de diferentes cultivares de aveia em pastagem de estrela-africana (Cynodon nlemfuensis vr. Nlemfuensis) manejada com diferentes resíduos de forragem. Os cultivares de aveia utilizados foram aveia preta comum (Avena strigosa), aveia branca comum (Avena sativa), aveia preta cultivar IAPAR-61 (Avena strigosa cv IAPAR-61), aveia branca cultivar IAPAR-126 (Avena sativa cv IAPAR-126). A pesquisa foi realizada na Universidade Tecnológica Federal do Paraná, Câmpus Dois Vizinhos, no período de 15/05/2009 e 26/10/2009. O delineamento experimental utilizado foi o bloco ao acaso, em um esquema fatorial 4 x 3 (quatro cultivares de aveia e três resíduos de estrela africana). Foram avaliados: massa de forragem, porcentagem dos componentes estruturais da forragem, produção total, produção total de aveia e colmo, produção de estrela africana e qualidade das forragens. Não houve interação entre cultivar e resíduo de forragem para nenhuma das variáveis estudadas. A pastagem sobressemeada com a aveia branca cv. IAPAR-126 apresentou maior produção de forragem total (aveia + estrela africana) (4.427,1 contra 2.384,0 kg de MS/ha) e de aveia (2.453,0 contra 1.588,7 kg MS/ha) em comparação à aveia preta comum. A aveia preta comum apresentou maior percentual de colmo (13,6 %) em relação a aveia branca cv. IAPAR-126 (5,4 %). A aveia branca comum apresentou maior teor de FDA no resíduo (estrela africana + aveia) em comparação a aveia branca IAPAR-126 (41,9 contra 36,3%). Já a aveia branca comum apresentou menor teor de FDN (49,0%) em relação à aveia branca IAPAR 126 (54,9%) e a aveia preta comum (57,0%). Em relação à proteína bruta, a aveia preta comum apresentou maior teor (15,6%) em relação as demais.

The oat cultivars used were black oat (Avena strigosa), common oat (Avena sativa), oat IAPAR-61 (Avena strigosa IAPAR cv-61), oat IAPAR-126 (Avena sativa IAPAR cv-126).

The overseeding of cool‐season species into dormant warm‐season species and tree inclusion in open pastures are potential options for improving forage quality and for extending the grazing period, thus contributing to sustainable livelihoods. However, warm‐season species respond differently to cool‐season overseeding. To our knowledge, there are no reports concerning the use of the overseeding method in limpograss [Hemarthria altissima (Poir.) Stapf & Hubb.] pastures, particularly in silvopastoral systems. A field experiment was conducted to evaluate the suitability of oat (Avena sativa L.) overseeding into a limpograss pasture in two systems located in a subtropical region, silvopastoral vs. open pasture, for three consecutive years. The presence of trees had a significant impact on dry matter yield and animal gain per hectare (Gha) during periods of drought. A maximum Gha of 363 kg live weight (LW) ha−1 was observed on limpograss pasture, over 139 days of grazing, after oat overseeding. In contrast, the maximum Gha on oat pasture was only 174 kg LW ha−1. However, it was still possible to obtain up to 112 grazing days in an area that would be fallow in winter. The maximum annual profit obtained was $ 673.0 ha−1 in the second year, with no differences between systems. To increase economic profits, farmers may search for strategies that add value to silvopastoral products.This article is protected by copyright. All rights reserved
