“…Thus, the selection of a cover crop to provide the amount of mulch biomass needed to maintain an integrated system should account for the climatic conditions of the region. In the Brazilian Cerrado (savannah), the winters are characterized by drought events and low humidity, while the summers have high temperatures and rainfall, which hinder the longevity of mulch biomass on the soil, as high temperature and humidity accelerate the decomposition rate the plant materials (Castro et al ., 2017).…”

Brachiaria and Panicum maximum in an integrated crop–livestock system and a second-crop maize system in succession with soybean

Owing to its contribution to the maintenance of carbon stocks, soil nitrogen and nutrient cycling for subsequent crops, the integrated systems become increasingly important for agricultural conservation. Thus, the objective of this study was to evaluate the biomass production of and total nutrient in Brachiaria spp. and Panicum maximum forage grasses used as mulch and soybean yields in an integrated crop–livestock system and second-crop maize succession system. The treatments consisted of the following cropping systems: Xaraes palisadegrass intercropped with soybean, Congo grass intercropped with soybean, Mombaça guinea grass intercropped with soybean, Tamani guinea grass intercropped with soybean and a soybean/maize succession system. The forage grasses were established during the soybean R6–R7 stage. Compared with Congo grass, Xaraes palisadegrass, Mombaça guinea grass and Tamani guinea grass produced more biomass and equivalent amounts of fertilizer returned to the soil and resulted in greater nutrient cycling, indicating the benefits of these grasses for use as mulch in integrated production systems. Maize had a greater C/N ratio, but the forage grasses also exhibited high potential by protecting the soil until the end of the soybean development cycle. The use of an integrated crop–livestock system combined with a forage cropping system provided greater soil nutrient cycling than the maize cropping system did, which resulted in increased soybean yields, thus contributing to the sustainability of agricultural systems.

“…Biomassa seca avaliada aos 118 dias após a semeadura A biomassa seca total obtida neste estudo para os tratamentos com monocultivo de CR foi inferior e a de MI superior (Tabela 1) ao alcançado por outros autores comoCastro et al (2017) que encontraram em seu trabalho para o MI e CR em monocultivo uma biomassa seca de, respectivamente 8.000 kg ha -1 e 2.300 kg ha -1 em diferente época de cultivo e aos 90 dias após plantio na região central de MG. No consórcio entre MI + CR na proporção de 50% de cada espécie, a biomassa seca total obtida no referido trabalho foi de 5.900 kg ha -1 , também inferior à obtida no presente trabalho.Os resultados obtidos para porcentagem de cobertura do solo nas diferentes épocas de avaliação estão representados na Figura 2 e Tabela 2. Não foi verificada interação significativa para porcentagem de cobertura do solo e épocas de avaliação (valor p= 0,47).…”

O objetivo neste trabalho foi avaliar a cobertura do solo proporcionada pela crotalária e milheto consorciados em diferentes proporções, bem como seus efeitos na qualidade física do solo. A instalação do experimento obedeceu ao delineamento em blocos casualizados. Os tratamentos foram constituídos de crotalária (Crotalaria spectabilis ) (CR) e milheto (Pennisetum glaucum L. ) (MI) consorciados em diferentes proporções de semeadura, totalizando seis tratamentos: 100% CR (crotalária solteira); 80% CR + 20% MI; 60% CR + 40% MI; 40% CR + 60% MI; 20% CR + 80% MI; 100% MI (milheto solteiro), com quatro repetições. As variáveis avaliadas foram a biomassa seca aos 118 dias após a semeadura, a porcentagem de cobertura do solo e umidade do solo aos 30, 60, 90 e 120 dias após o manejo das plantas, a resistência a penetração até 40 cm e densidade do solo na camada de 0-10. Aos 118 dias após a semeadura, a crotalária, o milheto e seus consórcios produziram quantidade de biomassa seca suficiente para promover a cobertura do solo de em média 77% até os 120 dias após o manejo das plantas, contudo não foram capazes de promover diferenças nos atributos físicos do solo.

Biomass production and soil coverage by the crotalary and millette consortium and its influence on physical properties AbstractThe aim of this work was to evaluate the soil cover provided by crotalaria and millet intercropped in different proportions, as well as their effects on the physical quality of the soil. The installation of the experiment followed the randomized block design. The treatments consisted of crotalary (Crotalaria spectabilis) (CR) and millet (Pennisetum glaucum L.) (MI) intercropped in different sowing proportions, totaling 6 treatments: 100% CR (single crotalary); 80% CR + 20% MI; 60% CR + 40% MI; 40% CR + 60% MI; 20% CR + 80% MI; 100% MI (single millet), with 4 repetitions. The variables evaluated were dry biomass at 118 days after sowing, the percentage of soil cover and soil moisture at 30, 60, 90 and 120 days after plant management, the resistance to penetration up to 40 cm and soil density in the 0-10 layer. At 118 days after sowing the crotalary, the millet and their intercropping produced enough dry biomass to promote an average 77% soil cover until 120 days after plant management, however, they were unable to promote differences in the physical attributes of the soil.
