Resumo: | The effects of soil management systems and crop rotation on sorghum yield characteristics agronomic were evaluated during the period 2003/04 to 2010/11 at EmbrapaTrigo, Passo Fundo, RS, Brazil. Four soil management systems: 1) no tillage, 2) minimum tillage, conventional tillage using a disk plow and a disk harrow, and 4) conventional using a moldboard and a disk harrow; and three crop rotation system I (wheat/soybean), system II (wheat/soybean and common vetch/sorghum), and system III (wheat/soybean, white oats/soybean and common vetch/sorghum) were compared. An experimental design of blocks at random, with split-plots and three replications, was used. The main plot was formed by the soil management systems, while the split-plot constituted of the crop rotation systems. Minimum tillage and no-tillage presented higher yield of sorghum, while conventional tillage using a moldboard plow remained in intermediate position and tillage using disk plow the lowest yield of sorghum. The yield of sorghum grown after common vetch in system II was higher than yield obtained for sorghum after common vetch in system I. No significant differences were observed in sorghum characteristics agronomic as a result of soil management and crop rotation systems. |

Four soil management systems: 1) no tillage, 2) minimum tillage, conventional tillage using a disk plow and a disk harrow, and 4) conventional using a moldboard and a disk harrow; and three crop rotation system I (wheat/soybean), system II (wheat/soybean and common vetch/sorghum), and system III (wheat/soybean, white oats/soybean and common vetch/sorghum) were compared.

O objetivo deste trabalho foi avaliar o efeito dos tipos de manejo de solo e de sistemas de rotação de culturas sobre o rendimento de grãos e as características agronômicas de sorgo, no período de 2003/04 a 2010/11, em Latossolo Vermelho Distrófico típico, na Embrapa Trigo, em Passo Fundo, RS. Foram comparados quatro tipos de manejo de solo: 1) plantio direto, 2) cultivo mínimo, 3) preparo convencional de solo com arado de discos e grade de discos e 4) preparo convencional de solo com arado de aivecas e grade de discos; e três sistemas de rotação de cultu- ras: sistema I (trigo/soja), sistema II (trigo/soja e ervilhaca/sorgo) e sistema III (trigo/soja, aveia branca/soja e ervilhaca/ sorgo). O delineamento experimental foi em blocos completos ao acaso, com parcelas subdivididas, e três repetições. A parcela foi constituída pelos tipos de manejo de solo, e as subparcelas, pelos sistemas de rotação de culturas. O cultivo mínimo e o sistema plantio direto apresentaram rendimento de grãos de sorgo mais elevado. O preparo con- vencional com arado de aivecas enquadrou-se em posição intermediária, enquanto o preparo convencional com arado de discos mostrou o menor rendimento de grãos de sorgo. O sorgo cultivado após ervilhaca no sistema II mostrou maior rendimento de grãos do que o sorgo cultivado após ervilhaca no sistema I. Não há diferença significativa nas características agronômicas de sorgo decorrentes do tipo de manejo de solo e dos sistemas de rotação de culturas.
