“…This confirms the feasibility of the winter sorghum intercropped with U. ruziziensis in the Cerrado biome, even using a high seeding density for the grass species. Similar result was found in other studies using lower seeding density for the grass species (Mateus et al, 2011;Horvathy Neto et al, 2012;Silva et al, 2013;2015).…”

“…Therefore, increasing winter U. ruziziensis seeding density in intercrop with sorghum increases the dry matter yields, in the Cerrado biome, region that presents less precipitation during winter. These increases increase the biomass production and soil plant coverage, which may favor the maintenance of the no-tillage system (Silva et al, 2013;2015;Borges, et al, 2016).…”

“…The intercrop of sorghum with grass species is a promising system that allows the production of grains and biomass in the winter (Mateus et al, 2011;Horvathy Neto et al, 2012;Silva et al, 2013;2015). Moreover, this biomass can be used as forage (Horvathy Neto et al, 2014;Silva et al, 2014).…”

The intercrop of grain sorghum with Urochloa ruziziensis allows the production of grains and biomass in the winter. Thus, the objective of this study was to identify the more adequate seeding system and seed density for Urochloa ruziziensis intercropped with sorghum between soybean crops to obtain high grain and biomass yields with these species and evaluate the performance of the subsequent soybean crop. The experiments were carried out in the winter of 2015 and in the 2015-2016 crop season in Rio Verde GO, and Santa Helena de Goiás GO, Brazil. The treatments consisted of three seeding systems (in-row, inter-row, and broadcast), and five seed densities (2, 4, 6, 8, and 10 viable seeds m-2) of U. ruziziensis intercropped with sorghum, using monocultures of sorghum and U. ruziziensis as controls. The seeding density of 8 viable seeds m-2 of U. ruziziensis using in-row seeding, and up to 10 viable seeds m-2 using inter-row, and broadcast seedings do not decrease sorghum grain yield. Increasing seeding density of U. ruziziensis increases its dry matter yield, and the total dry matter yield when intercropped with sorghum. The intercrop of sorghum with U. ruziziensis increases the soil plant coverage. The dry matter of the intercrop of sorghum with U. ruziziensis does not affect soybean grain yield.

“…Marandu, sown on the same date (Crusciol et al, 2011;Mateus et al, 2011). This difference can be explained by the installation method of palisadegrass, in these works it was sown in the fertilizer slot of sower machine, while in this oversowing (Pacheco et al, 2008), grown in row and between row of cultivated corn in the first season (Borghi et al, 2008), between the rows of corn grown in the second season (Alves et al, 2013), and in row and between rows of sorghum crop (Almeida et al, 2012;Silva et al, 2013).…”

The use of intercropping sorghum-palisadegrass for grain and straw production has become an advantageous cultivation option, can provide improvements in physical and chemical soil properties, maximizes production and income to the growers. There are still many management gaps to be improved in this intercropping in order that grower has the best outcome. Considering this, the objective of this study was to evaluate different sowing dates of palisadegrass in relation to sorghum, and evaluate the yield of soybean cultivated in succession. Palisadegrass was sown in monocrop and also between the lines of sorghum at different times (0, 15 and 25 days after sowing sorghum), as well the sorghum in monocrop. Soybeans were grown in succession on the straw of the mentioned treatments. It was evaluated biomass production and grain yield. Sowing palisadegrass and sorghum on the same day reduced sorghum grain yield and the palisadegrass biomass production. However, if palisadegrass are sowed 15 days after sorghum sowing, did not reduce the sorghum grain yield. Also, if the producer aims to produce sorghum grains, it is better to delay the sowing of palisadegrass in relation to sorghum. Although, if the producer aims to produce residual dry biomass, it is better to sow palisadegrass on the same day as sorghum or monocrop palisadegrass. Soybean yield did not differ among treatments when grown on different straws in the first year of cultivation.

“…A inclusão de gramíneas forrageiras, como as braquiárias, nos sistemas consorciados, permite o aumento da produção de biomassa nas áreas agrícolas dos cerrados (Horvathy Neto et al, 2012Silva et al, 2015). Além disso, a forrageira em questão apresenta sistema radicular abundante, o que contribui para a infiltração de água, além de favorecer a agregação e a aeração do solo (Silva et al, 2013). Pode-se destacar também o auxílio no controle de plantas daninhas pelo aumento da cobertura sob o solo (Lima et al, 2014), o que contribui para aumentos nos teores de matéria orgânica nas camadas superficiais do solo, além da rotação de culturas na área (Loss et al, 2013).…”

RESUMO -O consórcio de sorgo com braquiária é uma técnica de cultivo promissora para produção de grãos e biomassa. No entanto, há carência de informações em relação à escolha de híbridos graníferos para serem consorciados com espécies de braquiária para cultivo nos cerrados. Portanto, o objetivo do trabalho é testar híbridos de sorgo granífero em consórcio na linha com diferentes espécies de braquiárias para produção de grãos e biomassa, em dois cortes, na região dos cerrados. O ensaio foi implantado em campo, em Rio Verde-GO, na safrinha de 2010, empregando os híbridos de sorgo BRS 310 e DKB 599 consorciados na linha com as espécies Urochloa brizantha cvs. Marandu, Xaraés e Piatã, U. decumbens e U. ruziziensis, além dos tratamentos adicionais referentes aos monocultivos de sorgo e das espécies de braquiárias. Os resultados obtidos permitiram constatar que o consórcio de sorgo granífero com espécies de braquiárias afetou a população de plantas e o rendimento de grãos do sorgo, além do perfilhamento da braquiária. Contudo, o consórcio de sorgo e braquiária em safrinha nos cerrados apresentou potencial de adoção para produção de grãos e biomassa na entressafra.

GRAIN SORGHUM HYBRIDS INTERCROPPED WITH BRACHIARIAS IN OFF-SEASON CULTIVATION TO PRODUCE GRAINS AND BIOMASSABSTRACT -The sorghum and Urochloa intercropping is a promising technique to produce grains and biomass. However, there is lack of informations about the choice of grain sorghum hybrids to be intercropped with Urochloa species at Brazilian cerrado. Therefore, the objective of this work was to evaluate grain sorghum hybrids in intercropping at line with different species of Urochloa to produce grain and biomass in two cuts at cerrado region. The experiment was installed in the field, in Rio Verde, State of Goiás, Brazil, in the 2010 off-season cultivation. It was used the grain sorghum hybrids BRS 310 and DKB 599 intercropped at line with the species Urochloa brizantha cvs. Marandu, Xaraés and Piatã, U. decumbens and U. ruziziensis, and the treatments the Urochloa and sorghum monocrops. The results revealed that the grain sorghum intercropped with Urochloa species affected the plant population and grain yield of sorghum crop, beyond the tillering of Urochloa. However, Urochloa and sorghum intercropping in off-season cultivation has the potential adoption at Brazilian cerrado to produce grain and biomass.
