- Productivity of Tifton 85 grass irrigated and overseeded with winter forages Éder Pereira Gomes Max Emerson Rickli Ulysses Cecato Camila Viana Vieira Farhate Rafael Henrique de Tonissi e Buschinelli de Goes Elir de Oliveira Agrociencias rye Oats leaf stem ratio morphological composition 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 produc tivity and morpho logical compositio n of the Tifton 85 grass overseeded with winter forage in irrigated system. The experiment was a randomized block design with four replicates and repeated me asures 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 overseed ing. The overseeding of IPR 126 oats achieved the hi ghest cumulative productivity, 4102 kg DM ha -1 , with leaf/stem ratio higher than that of exclusive Tifton 85 exclusive, 1.77 and 1.08, respectively. However, overseeding of winter forages did not increase th e overall productivity of the pasture. 2015 artículo científico 1806-2636 https://www.redalyc.org/articulo.oa?id=303138476004 en http://www.redalyc.org/revista.oa?id=3031 Acta Scientiarum.
