“…Once exposed to radiation, seeds are easier to lose water to the atmosphere, which negatively affects the establishment of seedlings. Still, B. ruziziensis had the highest tillering capacity, both in intercrop and monocrop, similar to that observed in other studies (HORVATHY NETO et al, 2012;SILVA et al, 2014).…”

The grain sorghum intercropped with Brachiaria provides the production of grains and dry mass in the off-season; however, there is a lack of information related to the implantation of these species. The objective of this study was to identify the best association of sorghum and Brachiaria in the production of grain and dry matter in the Brazilian Cerrado region. The experiment was conducted in Rio Verde, State of Goiás, in the experimental design of randomized blocks, in a 2×3×4+5 factorial scheme, with four replications. Two sorghum hybrids (BRS 330 and DKB 551) associated to three Brachiaria species (Brachiaria brizantha cultivar Marandu, Brachiaria decumbens and Brachiaria ruziziensis) were evaluated in four systems of Brachiaria implantation (row, interrow, row + interrow of sorghum and spread). Additional treatments referred to the two sorghum monocrops and the three Brachiaria species. The sorghum and Brachiaria consortium resulted in a reduction in grain yield, but the Brachiaria implantation systems in the row, interrow and spread were the most promising. The sorghum hybrid DKB 551 was the most sensitive to the competition with Brachiaria, although there were no grain yield differences in the intercropping. The Brachiaria intercropped in the interrow and in the row + interrow, mainly with B. ruziziensis, were the most promising for the production of dry mass and total crude protein. The cultivation of Brachiaria intercropped with sorghum provided a greater contribution of dry mass in the off-season, an important fact for the no-tillage system in the agricultural production systems of the Brazilian Cerrado.

“…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).…”

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.

The intercropping of annual crops with perennial grasses is a production system that is frequently adopted in the Midwest region of Brazil due to its economic viability resulting from the use of the same area for agriculture and livestock. Most agriculture-livestock integration studies have evaluated the use of forage of the genus Urochloa in intercropped systems with corn, sorghum and sunflower. Consequently, there is a lack of information regarding pearl millet cultivation when grown simultaneously with tropical forages. Thus, the objective of this study was to evaluate the agronomic characteristics of pearl millet Pennisetum glaucum (L.) R. Br as well as the production and nutritional characteristics of Paiaguas palisadegrass (Urochloa brizantha cv. Paiaguas) under different forage systems and sowing periods in the offseason. The experiment was conducted at the Federal Institute of Goiás, Rio Verde campus. The experimental design was a randomized complete block with a 5 × 2 factorial arrangement and three replications. There were two sowing periods (February and March) and five forage systems: monocropped pearl millet; monocropped Paiaguas palisadegrass; pearl millet intercropped in rows with Paiaguas palisadegrass; pearl millet intercropped between rows of Paiaguas palisadegrass and pearl millet oversown and intercropped with Paiaguas palisadegrass. The results indicated that the Paiaguas palisadegrass did not affect the pearl millet grain yield, indicating that the intercropping of pearl millet and Paiaguas palisadegrass in the offseason is a promising cultivation technique for the production of grains during the offseason in Southeastern Goiás. However, the second sowing period provided better grain yields and a higher number of sacks per hectare. With respect to forage yield, the Paiaguas palisadegrass sown in oversown pearl millet was impaired by the intercropping and produced low forage yield. With respect to forage quality, the intercropped sowing system did not affect the nutritional characteristics of the Paiaguas palisadegrass.
