| description | The objective of this study was to evaluate the nutritional and productive performance of forage sorghum in an intercropping with soybean submitted to nitrogen doses. The experiment was in blocks with a complete randomized design, with four repetitions in a factorial arrangement (6x2+1), with six doses of nitrogen (0, 20, 40, 60, 80 e 100 kg de N ha-1), in two systems, being the intercropping of sorghum x soybean and one control with only sorghum with an application of 100 kg de N ha-1. The variables studied were sorghum dry and fresh matter productivity, crude protein of sorghum, fresh matter productivity for the intercropping and protein efficiency index. Higher doses of N applied as cover on the sorghum x soybean intercropping increased the quality and the productivity of the forage, when compared to the monoculture. The sorghum intercropping with two lines of soybean provides higher productivities of fresh matter, dry matter and crude protein. The intercropping with one and two lines of soybean provides a saving of 40% and 60%, respectively, of nitrogen on the production of crude protein when compared to monoculture. |

The objective of this study was to evaluate the nutritional and productive performance of forage sorghum in an intercropping with soybean submitted to nitrogen doses.

O objetivo deste trabalho foi avaliar o desempenho produtivo e nutricional de sorgo forrageiro consorciado com soja e submetido a doses de nitrogênio. O delineamento utilizado foi em blocos ao acaso com quatro repetições em esquema fatorial (6 x 2 + 1) sendo seis doses de nitrogênio (0, 20, 40, 60, 80 e 100 kg de N ha-1), dois sistemas de consórcio sorgo x soja e uma testemunha constituída de sorgo solteiro com aplicação de 100 kg de N ha-1. As variáveis avaliadas foram produtividade de matéria fresca e seca do sorgo, proteína bruta do sorgo, produtividade de matéria fresca e seca do consórcio, proteína bruta do consórcio e índice de eficiência de proteína bruta. Maiores doses de N aplicadas em cobertura no consórcio sorgo x soja, elevam a produtividade e qualidade nutricional da forragem em relação ao monocultivo. O consórcio de sorgo com duas linhas de soja proporciona maiores produtividades de matéria fresca, matéria seca e proteína bruta. O consórcio com uma e duas linhas de soja proporciona economia de 40% e 60% de nitrogênio na produção de proteína bruta em relação ao monocultivo de sorgo, respectivamente. 2016-11-04 2022-03-21T20:07:36Z 2022-03-21T20:07:36Z info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion https://comunicatascientiae.com.br/comunicata/article/view/991 10.14295/cs.v7i2.991 http://biblioteca-repositorio.clacso.edu.ar/handle/CLACSO/77754 por https://comunicatascientiae.com.br/comunicata/article/view/991/399 application/pdf Federal University of Piauí Comunicata Scientiae; Vol. 7 No. 2 (2016); 204-208 Comunicata Scientiae; v. 7 n. 2 (2016); 204-208 2177-5133 2176-9079 |
