The vegetables intercropping practice triumph in family farming depends on several production factors, including the crops involved, green manuring and plant density of component crops. Therefore, the aim of this work was to assess whether there is agro-economic viability in the radish-arugula intercropping, in different equitable amounts of M. aegyptia and C. procera biomass (20, 35, 50 and 65 t ha-1 on base dry) and in diverse arugula population densities (40, 60, 80 and 100% of that recommended density for single crop - RDSC), combined with 100% of the RDSC for radish in two cropping years. The characteristics, the commercial productivity of radish roots and the arugula green mass yield were evaluated and in the intercropped system, the agronomic indices: land equivalent ratio (LER), intercropping advantage (IA), actual yield loss (AYL), productive efficiency index (PEI), score of the canonical variable (Z), and the economic indicators: gross income (GI), net income (NI), rate of return (RR) and profit margin (PM). The greatest agro-economic advantages of the radish-arugula intercropping were achieved with an LER of 1.64, PEI of 0.86, Z of 1.54, GI of R$ 45,543.92 ha-1, NI of R$ 24,662,31 ha-1, RR of R$ 2.20 for each real invested, and PM of 56.37%, respectively, in the combination of 65 t ha-1 of M. aegyptia and C. procera biomass and arugula population density of 100% of the RDSC, corresponding to the density of 1 million plants per hectare.

“…Posteriormente foi realizado o processo de solarização, com plástico transparente 'Vulcabrilho Bril Fles' de 30 micras, durante 45 dias com o intuito de reduzir a população de fitopató-genos habitantes do solo, que viessem a prejudicar a produtividade das culturas (Oliveira et al, 2015).…”

R E S U M OO objetivo deste trabalho foi avaliar as propriedades microbiológicas e nutricionais do solo, no consórcio de beterraba e rúcula, em função de quatro quantidades de flor-de-seda (Calotropis procera) incorporadas ao solo e de arranjos espaciais. O delineamento experimental foi de blocos completos casualizados com cinco repetições, com os tratamentos arranjados em esquema fatorial 4x3. Os tratamentos consistiram em quatro quantidades de flor-de-seda incorporadas ao solo (10; 25; 40 e 55 t ha -1 de matéria seca) e em três arranjos espaciais (2:2, 3:3 e 4:4). As cultivares plantadas foram: beterraba 'Early Wonder', e rúcula 'Cultivada'. As características avaliadas no solo foram os teores de: N, P, K, pH, CTC, matéria orgânica, bactérias e fungos totais presentes no solo, antes do plantio e após a colheita das culturas. O melhor desempenho microbiológico e nutricional foi registrado na segunda época de colheita do solo na quantidade de 55 t ha -1 . Os arranjos espaciais entre as culturas da beterraba e rúcula não influenciaram as características nutricionais e microbiológicas do solo. O número total de fungos e bactérias do solo aumentou com as quantidades crescentes da flor-de-seda incorporadas ao solo.

The experimental design was in randomized complete blocks with five replications, with the treatments arranged in a 4x3 factorial scheme. The treatments consisted in combinations of four amounts of roostertree incorporated into the soil (10, 25, 40 and 55 t ha -¹ of dry matter) and three spatial arrangements (2:2, 3:3 and 4:4). The planted cultivars were of beet 'Early Wonder' and of rocket were 'Cultivada'. The characteristics evaluated in the soil were the contents of N, P, K, pH, CEC, organic matter, bacteria and fungi present in soil before sowing and after the crop harvest. The best microbiological and nutritional performance of the soil was registered in the second times and in the amount of 55 t ha -¹. The spatial arrangements do not influence the nutritional and microbiological characteristics of the soil. The total number of fungi and bacteria in the soil increased with increasing amounts of the roostertree incorporated into the soil.Keywords: Beta vulgaris, Calotropis procera, Eruca sativa, Intercropping system, organic fertilization. INTRODUÇÃOA utilização de espécies vegetais como adubos verdes, influencia a microbiota do solo relativamente à quantidade, diversidade e ao seu desenvolvimento. Acredita-se que quanto maior é a quantidade de material orgânico incorporado ao solo, maior será a biomassa microbiana. Esta sucessão de ciclos biológicos é um dos componentes que controla as funções chaves do solo, como a
