Resumo: | The adaptation of Urochloa brizantha to Brazilian ecosystems and the use of artificial shading in low light production studies are important tools to obtain productive responses and to know the behavior of plants when used in integration with arboreal components. The experiment was conducted at the FMVZ - UNESP in Botucatu city, São Paulo state, Brazil. The study aimed to evaluate the yield of U. brizantha (syn Brachiaria brizantha) cv. Xaraés (Xaraés palisade grass) under three light intensities and four cuts. The experimental design was a randomized block with three treatments (natural luminosity, 30% light reduction, and 60% light reduction), three replicates and four cuts. The following morphological components were determined: leaf area index (LAI), forage accumulation rate (FAR), total forage mass (TFM), stem yield (SY), leaf yield (LY), and dead material yield (DMY). Light intensity influenced grass productivity, and the best performance was reached under 60% shading, which had higher values of TFM, LY, SY, LAI, and FAR if compared to natural luminosity. Thus, a reduction of 60% in light intensity showed to be the most productive and the best alternative under those conditions. |

O experimento foi conduzido na FMVZ – UNESP Botucatu, com objetivo de avaliar a produtividade da cultivar de Urochloa brizantha (syn Brachiaria brizantha) cv. Xaraés submetida a três intensidades luminosas e quatro cortes. O delineamento experimental foi em blocos ao acaso, sendo os tratamentos: luminosidade natural, redução de 30% e 60% de luz, com três repetições e quatro cortes. Foi realizada a separação morfológica, índice de área foliar e a taxa de acúmulo, também foi calculada a produção de massa seca total, colmo e folhas, além da produção de material morto. A produtividade foi influenciada pelos níveis de intensidade de luz, sendo o melhor desempenho obtido no tratamento com 60% de sombreamento, que apresentou maior produção de massa seca total, de folha e colmo, índice de área foliar e maior taxa de acúmulo em comparação ao pleno sol. O tratamento com 60% de redução de luminosidade foi o mais produtivo, sendo o melhor tratamento nestas condições.UEL2019-08-29info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionDesempenho agronômico sob influência de luzapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/3483010.5433/1679-0359.2019v40n6p2749Semina: Ciências Agrárias; Vol. 40 No. 6 (2019); 2749-2758Semina: Ciências Agrárias; v. 40 n. 6 (2019); 2749-27581679-03591676-546Xreponame:Semina.
