No-tillage (NT) agriculture represents a great advance in soil conservation in tropical and subtropical zones, occupying more than 32 million ha in Brazil in 2017. No-tillage systems can promote earthworm populations, which can improve soil physical and chemical properties, thus enhancing the benefits of NT for soil conservation and ecosystem services. Furthermore, earthworms can be used as indicators of the quality of NT systems. Here, we summarize the studies that evaluated earthworm populations in NT systems between 1986 and 2016 in Brazil, highlighting important gaps in knowledge. The studies were highly skewed geographically, with most data from southern and south-eastern Brazil, and had very little information from the two states with the greatest NT area (Mato Grosso and Rio Grande do Sul) which together represent 43% of Brazilʼs NT area. Abundance values ranged from 0 to 660 ind. m−2 , with a mean of 91 ± 129 ind. m−2 (±SD), and at least 33 species were identified in NT systems. However, 73% of sites were considered to have poor and moderate soil quality based on their earthworm populations, raising concern regarding soil quality levels in Brazilian NT systems. Climate, soil and management conditions are important drivers of earthworm populations in Brazilian NT systems and future earthworm surveys in NT systems should provide ample data on these attributes, as well as on earthworm species, in order to improve their use as soil quality bioindicators. |

Brazil is the world?s largest sweet orange producer, but production in the state of Acre is small and does not meet the local demand, despite having climatic conditions that are adequate for its cultivation. The objective of this study was to evaluate the behavior of the ?Pera? orange using different rootstocks under the edaphoclimatic conditions of Rio Branco, Acre, Brazil. We grafted the scion of the ?Pera? orange onto nine citrus rootstocks: ?Cleopatra? mandarin, TSKFL x CTTR ? 013, LVK x LCR ? 038, TSKC x CTQT 1439 ? 004, LVK x LVA ? 009, ?Indio?citrandarin, ?Santa Cruz Rangpur? lime, TSKFL x CTC - 25 ? 002, and TSKC x CTSW ? 038. The experiment was organized in a random block design with three replicates and two plants per parcel. The following characteristics were evaluated: compatibility between scion and rootstocks, tolerance to drought, production and fruit quality. There was an effect of the rootstocks on the behavior of the ?Pera? variety. The ?Santa Cruz Rangpur? lime, ?Indio? citrandarin, and the hybrid LVK x LCR - 038 rootstocks presented the best performance of the ?Pera? orange. Therefore, they constitute an alternative to the ?Rangpur? lime and may be incorporated into the current ?Pera? orange production system of the region.
O Brasil é o maior produtor mundial de laranja-doce, mas no Estado do Acre a produção é pequena e não atende à demanda local, apesar de possuir condições climáticas adequadas ao seu cultivo. O objetivo do trabalho foi avaliar o comportamento de laranjeira ?Pera? sobre diferentes porta-enxertos nas condições edafoclimáticas de Rio Branco, Acre. A copa de laranjeira ?Pera? foi enxertada em nove porta-enxertos de citros: ?Cleópatra?, TSKFL x CTTR ? 013, LVK x LCR ? 038, TSKC x CTQT 1439 ? 004, LVK x LVA ? 009, Citrandarin ?Indio?, ?Santa Cruz Rangpur? lime, TSKFL x CTC - 25 ? 002 e TSKC x CTSW ? 038. Empregou-se um delineamento em blocos ao acaso com três repetições e duas plantas na parcela. Foram avaliadas características vegetativas, compatibilidade entre copa e porta-enxertos, tolerância à seca, produção e qualidade dos frutos. Houve efeito dos porta-enxertos sobre o comportamento da variedade copa. Os porta-enxertos limoeiro ?Cravo Santa Cruz?, citrandarin ?Indio? e o híbrido LVK x LCR ? 038 refletiram em melhor desempenho da laranjeira ?Pera?. Sendo assim, constituem como alternativas ao limoeiro ?Cravo? e podem ser incorporados ao atual sistema de produção de laranjeira da região.
