“…and C. M. Evard) Crins (Congo grass), a perennial tropical forage grass, in intercropping systems has been demonstrated to be feasible for farmers. Different intercropping arrangements can be used with no yield reduction in maize ( Zea mays L.) (da Silva et al., 2018; Kichel et al., 2018), sorghum ( Sorghum bicolor L.) (Buffara et al., 2018), sunflower ( Helianthus annuus L.) (Kimecz et al., 2018), castor ( Ricinus communis L.) (Cordeiro et al., 2019), and soybean Glycine max (L.) Merril (Erasmo et al., 2017). It is important to note that these grass intercrops often occur after grain crop emergence (Erasmo et al., 2017).…”

Intercropping perennial forage grasses into cereal crops is an alternative to recover degraded pastures. However, the intercrop of forage grasses, such as Urochloa ruziziensis (R. Germ. and C. M. Evard) Crins (Congo grass), can lead to losses in cereal yield. Therefore, it is necessary to develop management strategies that allow forage grass establishment without major losses in cereal yield in intercropping. The objective was to study the agronomic and economic impacts of intercropping U. ruziziensis into a Clearfield upland rice (Oryza sativa L.) cultivar in the state of Goiás, Brazil, in two growing seasons. Treatments included forage grass seeds sowing method (broadcast or incorporation to the soil) and sowing times (at rice sowing, 20 days after emergence [DAE], and 45 DAE of rice). Also, imazapyr + imazapic herbicide was applied to restrict the competitive effect on rice yield. Monocropping control plots were also evaluated. Grain yield was measured on rice. Forage grass dry matter yield was measured at 30, 60, and 90 days after harvesting (DAH) of rice. Crude protein content was analyzed at 90 DAH. Profitability was calculated for each cropping system relative to rice monocropping. Intercropping of rice and U. ruziziensis sowed at 45 DAE provided the highest grain yield relative to other assessed intercropping treatments as well as rice monocropping. Concurrent sowing of rice and incorporated U. ruziziensis seeding provided the greatest economic return. This reformed cropping system improved land and pasture output, which can reduce the pressure to convert more land to agricultural use.

“…Tropical forage species, mainly those from the Urochloa genus have been shown relative success to supply biomass for NTS in agricultural lands (Freitas et al, 2013;Santos et al, 2015;Da Silva et al, 2018). In this cropping system, the introduction of forage species can be made under intercropping with crops like maize (Kichel et al, 2018;Da Silva et al, 2018), sorghum (Buffara et al, 2018), sunflower (Kimecz et al, 2018) and soybean (Erasmo et al, 2017), either in a rotation cropping system or under monocropping aiming the straw production.…”

As espécies de forrageiras, em especial as do genêro Urochola tem sido uma importante alternativa para utilização no Sistema de Plantio Direto (SPD) devido a boa produção de biomassa e alta relação C/N. Essas características favorecem a persistência da palhada na área, principalmente em regiões como o Cerrado, onde as condições climáticas aceleram a decomposição da palhada. Contudo, para o bom desenvolvimento da cultura subsequente, deve-se realizar a dessecação dessas forrageiras de maneira eficiente, com a utilização de herbicidas. Deste modo, objetivou-se nesse trabalho a investigação da cinética de morte das forrageiras Urochola brizantha cv.Piatã, a U. brizantha cv. BRS Paiaguás, U. spp cv. Ipyporã e U. ruziziensis submetidas a diferentes doses do herbicida glifosato. Os tratamentos consistiram na combinação de quatro espécies forrageiras (Urochloa brizantha cv. BRS Paiaguás, U. ruziziensis, U. brizantha cv. Piatã e U. spp. cv. Ipyporã) submetidas à aplicação de quatro doses do herbicida glifosato (250; 500; 1000 e 2000 g de equivalente ácido de glifosato ha-1). Foram realizadas avaliações visuais do efeito fitotóxico aos 7, 14, 21 e 28 dias após a aplicação (DAA) do herbicida. Os resultados demonstram que as espécies possuem sensibilidade diferente ao herbicida glifosato, sendo que as U. brizantha cv. BRS Paiaguás e U. ruziziensis as mais susceptíveis ao herbicida. A cinética de morte das forrageiras é afetada pela dose aplicada do herbicida.

“…Cultivating brachiaria (Urochloa ruziziensis) in intercropping systems allows biomass production to successor crops and is beneficial mainly in low soil fertility (Cordeiro et al, 2019;Oligini et al, 2019). The initial development of the forage is slower, allowing the establishment of an annual crop of economic interest without reducing yield potential (Kimecz et al, 2018).…”

The maize and Urochloa ruziziensis intercropping have potential use for agricultural production systems, allowing the production of grains and biomass. The study aims to evaluate the yield and economic viability of corn and U. ruziziensis intercropping modalities in the northwestern region of Paraná. The experiment was conducted in Maringá-PR in a completely randomized design with five treatments (single corn; single U. ruziziensis; U. ruziziensis between the corn rows; corn with U. ruziziensis in the same row; corn rows interspersed with U. ruziziensis rows) and four replicates. Initial development, grain yield of corn, and the production of biomass of corn and U. ruziziensis were evaluated. The data were submitted to analysis of variance. The means were compared by the Tukey test at 5% probability. In the initial development of corn plants, there was no significant difference due to intercropping. U. ruziziensis in the intercropped system had a reduction in biomass production. Intercropping with corn rows interspersed with U. ruziziensis rows had grain yield higher than other intercropping modalities and similar to single corn cultivation
