Efeito da altura e intervalo de corte do capim-elefante-anao. I. Producao e qualidade da forragem. Repositório Alice
ACUNHA, J.B.V.; COELHO, P.W..
O experimento foi conduzido em area pertencente a EMBRAPA-Centro de Pesquisa Agropecuaria de Clima Temperado (CPACT), Pelotas, RS , no periodo de novembro de 1992 a abril de 1993, com o objetivo de estudar o efeito da altura e do intervalo de corte sobre a producao e qualidade do capim-elefante-anao cv. Mott. Utilizou-se o delineamento completamente casualizado, com parcelas divididas em tres repeticoes. As parcelas corresponderam as alturas de corte (5,1 e 15 cm acima do nivel do solo), e as subparcelas, aos intervalos de corte (28,56,84,112 e 140 dias). A analise dos resultados obtidos permitiu concluir que o intervalo de corte de 56 dias e o mais indicado para utilizacao animal, independentemente da altura de corte, na qual nao foi detectada...

The forage mass, sward structure, the ingestive and grazing behavior and forage intake by goats grazing on Tanzania-grass at 22 and 37 days of regrowth were evaluated. A completely randomized experimental design was used, with eight replications for evaluating the pasture and bite depth, and six replications for evaluating intake, feeding and grazing behavior. The forage canopy height ranged from 64.1 to 92.7 cm. Higher forage mass was observed at 37 days, and the best leaf/stem ratio, at 22 regrowth days. The bite depth did not differ between regrowth ages. The biting rate for the 22 regrowth days (23.07 bites min.-1) was higher than at 37 days (19.06 bites min.-1). The grazing time was longer at the regrowth age of 22 days (5.58h) than at 37 days...

Forage mass and agronomic traits of Elephant grass genotypes under free-growth and conventional cutting systems. Repositório Alice
GIMENES, F. M. de A.; BERNDT, A.; MATEUS, G. P.; LEDO, F. J. da S.; DEMARCHI, J. J. A. de A.; GIACOMINI, A. A.; GERDES, L.; BATISTA, K..
Abstract Few grass genotypes with high yield potential are used as fodder in Brazil, making it necessary to develop new cultivars. In this study, we compared tiller density, forage mass, and agronomic traits across 12 Elephant grass (Pennisetum purpureum Schum.) genotypes under free-growth and conventional cutting systems at the Agência Paulista de Técnologia dos Agronegócios (APTA), Andradina, São Paulo, Brazil. The experimental design of the two trials was three replicates of a randomized complete block, each experimental unit consisting of 37.5-m2 plots with five rows spaced 1.5 m apart. We estimated tiller density 30, 60, and 150 days after planting (DAP), and 90 days after cut (DAC), and harvested the grass 150 DAP and 90 DAC for determination of...

Nutritional Value of Marandú Palisade Grass According to Increasing Coexistence Periods with Weeds Planta Daninha
BELLÉ,J.R.; MARCHI,S.R.; MARTINS,D.; SOUSA,A.C.; PINHEIRO,G.H.R..
ABSTRACT: This research aimed at evaluating the effect of increasing coexistence periods with weeds on the nutritional components of the forage grass Brachiaria brizantha cv. Marandú under pasture renewal conditions. The experiment was arranged in randomized blocks with four replications, and treatments were represented by eight coexistence periods, namely: 0, 15, 30, 45, 60, 75, 90 and 120 days after seedling emergence. A phytosociologic evaluation was performed on the weed community at the end of the coexistence periods; later, weeds were eliminated by an herbicide formulated with aminopyralid+2,4-D (40+320 g L-1) at 2.5 L ha-1, applied in post-emergence. The fodder plants were evaluated at the end of the experimental period as for leaf-stem ratio,...

Productivity of Tifton 85 grass irrigated and overseeded with winter forages Animal Sciences
Gomes, Éder Pereira; Rickli, Max Emerson; Cecato, Ulysses; Farhate, Camila Viana Vieira; Goes, Rafael Henrique de Tonissi e B. de; Oliveira, Elir de.
Intercropping with cool season species has been used as an alternative to increase productivity off-season (fall/winter) of irrigated pastures. This study was conducted from May to October 2009 in Icaraíma, Paraná State, to evaluate the productivity and morphological composition of the Tifton 85 grass overseeded with winter forage in irrigated system. The experiment was a randomized block design with four replicates and repeated measures over time. The experimental plots consisted of five treatments, three as oats overseeding using the genotypes IAPAR 61, IPR 126, and FMS2 on Tifton 85 pasture and one as overseeding of oats combined with rye (IPR 126 + IPR 89) also on Tifton 85 grass and, finally, a control with only Tifton 85 without overseeding. The...

Pereira,Rosana Cristina; Ribeiro,Karina Guimarães; Andrade,Rodrigo Duarte de; Silva,Janaina de Lima; Silva,Enilson de Barros; Fonseca,Dilermando Miranda da; Cecon,Paulo Roberto; Pereira,Odilon Gomes.
The objective of this study was to assess the effect of applying N and K2O at different times after harvest on the structure and production characteristics of Marandu and Xaraés cultivars of Brachiaria brizantha. Two greenhouse 4 × 2 factorial experiments using a randomized block design with eight treatments and four replicates were carried out. In experiment 1, the plants in pots were fertilized weekly with 50 mg/dm³ of N and K2O until a week before a uniformity cut, for a total of four applications. After cutting, plants were fertilized with 50 mg/dm³ of N and K2O at 0, 3, 6, and 9 days. Cultivars were evaluated after 44 days of regrowth. In experiment 2, a single 50 mg/dm³ dose of N and K2O was applied a week before the uniformity cut, and 100 mg/dm³ of...
