“…No grain yield difference between monocropped maize and intercropped maize-Panicum spp. has been reported by Almeida et al [36], which agree with the present results and shows the viability of this kind of management in crop and livestock integration systems, as also described to other kind of tropical grasses [37].…”

Mycorrhizae are important components of agroecosystems and the diversification of crops stimulates the abundance of arbuscular mycorrhizal fungi and the participation of symbiosis in plant growth. This experiment examined mycorrhizal assessment, chemical and microbiological soil attributes in a maize-forage grasses intercropping compared to a maize-monocropping system. A complete randomized block design was used with crop systems installed under no-till management with three replicates, as follow: Maize (Zea mays L.); Panicum maximum Jacq. cv. Aruana; Urochloa humidicola (Rendle.) Schweickerdt.; Maize-P. maximum intercropping and Maize-U. humidicola intercropping. In 2015/2016 season, intercropping maize with Panicum maximum Jacq. cv. Aruana or Urochloa humidicola (Rendle.) Schweickerdt. promoted similar effects (Tukey test, p<0.05) to monocropped maize under no-till system on soil HIGHLIGHTS • Maize-forage grasses promoted effects similar to monocropped maize under no-till system. • Intercropping maize-tropical forage grasses represents an alternative for monocropped grains. Maize-forages intercropping presented high rates of mycorrhizal colonization. 2 Méndez, D.F.S..; et al.

Plant diversity is associated with resilient ecosystems. Loss of plant biodiversity triggered by anthropogenic and climatic factors jeopardizes environmental stability and sustainable forage production. The understanding of biodiversity mechanisms and functional traits of species can help to design forage production systems to buffer against perturbations. Resilience and productivity are linked to plant species characteristics and interactions that enable them to recover from adverse conditions and compensate for the loss of susceptible species. Benefits of diversified crops including enhanced carbon assimilation, nitrogen fixation, and turnover are transferred to soil microbes which in return contribute to resilience against drought and poor soil fertility. In the absence of disturbances, these mechanisms are credited for stability and climax ecosystems. Cultivated systems are more fragile because management interferes with many functions while maintaining few. Strategies that sustain an entire range of functions can increase production regardless of climatic and management factors. This has been demonstrated in binary mixtures of cool season grasses including meadow bromegrass (Bromus biebersteinii Roem. & Schult.), orchardgrass (Dactylis glomerata L.), smooth bromegrass (Bromus inermis Leyss.), and intermediate wheatgrass (Thinopyrum intermedium (Host) Barkworth & D.R. Dewey) with alfalfa (Medicago sativa L.). Suitable combinations of perennial species and cultivars bred for compatible traits can enhance resilience and productivity in a wide range of ecosystems.

“…In the Cerrado, intercropping between corn and forage crops is a technology that allows maintaining corn grain production and increasing straw production in order to enable no-tillage with soybean-corn succession (QUEIROZ et al, 2016;ALMEIDA et al, 2017). The use of no-tillage system (NTS) in areas with a deficiency of straw or soil cover leads to an increase in the infestation of herbicide-tolerant or resistant weeds and hence to a reduction of up to 50% in soybean yield when compared to sowing carried out on straw of Urochloa spp., which presents high yield and long persistence (LAMAS, 2008).…”

SUPPRESSION OF Urochloa brizantha AND U. ruziziensis BY GLYPHOSATE UNDERDOSES

Intercropping of Urochloa species with corn is an alternative to enable the no-tillage system, besides influencing weed community. Therefore, the investigation of underdoses of the herbicide glyphosate to manage grasses in intercropping systems, avoid grain yield losses, and make feasible intercropping in agricultural areas is important. This study aimed to evaluate glyphosate underdoses in the suppression of Urochloa brizantha cv. Marandu and Urochloa ruziziensis and weed control. Two tests were conducted under field conditions in a randomized block design with four replications and eight treatments consisting of increasing glyphosate doses (0, 54, 108, 270, 378, 540, 756, and 1.080 g a.e. ha−1). All treatments received a dose of 1.200 g a.i. ha−1 of atrazine. Evaluations of phytointoxication of brachiaria plants were carried out at 7, 14, 21, and 28 days after application. Moreover, total dry matter, leaf dry matter, stem dry matter, leaf to stem ratio, and canopy height of brachiaria plants and density and dry matter production of weed community were evaluated at 80 and 125 days after sowing. Glyphosate underdoses lower than 238 and 105 g a.e. ha−1 have potential to be investigated aiming at the management of U. brizantha cv. Marandu and U. ruziziensis, respectively.
