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.

“…Among other benefits, the practice of green manuring can contribute to meeting the nutritional needs of the crop. In addition, it preserves, restores and increases the amount of organic matter and the soil nutrient contents (BATISTA et al, 2016), favouring the sustainable use of physical, chemical and biological factors.…”

The introduction of new crops in northeastern Brazil, associated with the use of the green manure, can become an alternative for family farmers. Thus, the objective of this work was to determine the effect of green manuring with M. aegyptia L. on the agro-economic efficiency of radish production. The experimental design was a randomised complete block with four treatments and five replicates; the treatments were composed of four doses of M. aegyptia (20, 35, 50 and 65 t ha-1 on a dry basis) incorporated into the soil in three cropping periods. In radish plants, we evaluated plant height, fresh and dry mass of shoots, total and commercial productivity of roots, productivity of scrap roots, dry mass of roots and root diameter. The economic indicators gross income, net income, rate of return and profit margin were used to evaluate the agro-economic efficiency of the system. The maximum agronomic efficiency was reached with a commercial root productivity of 7.86 t ha-1 and the addition of 49.29 t ha-1 of green manure. The maximum economic efficiency was obtained with a net income of 11,955.46 R$ ha-1 when a green manure dose of 46.00 t ha-1 was added. The use of M. aegyptia as green manure is economically viable in the production of radish in the semi-arid region of Northeast Brazil.

“…No entanto, a eficiência do consórcio de cultivos depende da densidade e do tipo de cada espécie vegetal que compõe o sistema para se complementarem mutuamente (DE VASCONCELOS BATISTA et al, 2016). Os autores observaram que a eficiência técnica da cenoura e da rúcula no Nordeste brasileiro depende da manipulação das densidades populacionais.…”

Uma forma de reduzir incertezas da produção e obter economia de escopo é por meio do emprego da diversificação de atividades, que pode ser entendida por diferentes conceitos e abordagens. O presente trabalho tem como objetivo apresentar arcabouço teórico e empírico da diversificação agropecuária no Brasil, utilizando abordagens socioeconômica e agronômica. Além disso, apresenta-se as possíveis formas de diversificação agropecuária, ressaltando sua importância ambiental e econômica. Para isso, apresenta-se a evolução da produção agropecuária municipal a partir de dois índices: Shannon e Simpson, no período1987-2017. Os resultados revelam tendência à especialização de culturas, especialmente na região Centro-Oeste. No entanto, a produção agropecuária municipal ainda se encontra na categoria “diversificada” nesse período. Os estabelecimentos acima de 1000 hectares têm uma relação negativa com a diversificação agropecuária, contrária aos estabelecimentos entre 0 a 50 hectares da região Sul e Centro-Oeste.
