Summary
Foram conduzidos dois experimentos no Sistema Integrado de
Produção Agroecológica, em Seropédica, (RJ), durante dois anos consecutivos. O objetivo foi avaliar o desempenho do consórcio entre as culturas de repolho e rabanete com pré-cultivo de crotalária, sob manejo orgânico. Usou-se delineamento experimental de blocos ao acaso com sete repetições, em parcelas subdivididas, representando um fatorial 2 x 3, sendo o primeiro fator o pré-cultivo, com Crotalaria juncea e pousio (vegetação espontânea); e o segundo fator o sistema de cultivo (consórcio entre repolho e rabanete e os respectivos monocultivos). Não houve diferença significativa no tocante à produtividade do repolho ou rabanete, entre C. juncea e pousio, independentemente do tipo de manejo (monocultivos ou consórcio). O desenvolvimento do repolho não foi influenciado pela presença do rabanete, no consórcio entre essas espécies sob cultivo orgânico. O rabanete sob consórcio apresentou redução no diâmetro médio, massa
média e produtividade de raízes, sem, contudo,desqualificar o padrão comercial das raízes colhidas. Considerando a média dos dois anos experimentais, o IEA atingiu 1,59, o que indicou a viabilidade do consórcio, otimizando práticas culturais, incluindo adubação,capina e irrigação.
Summary translation
Field experiments were carried out during two consecutive years in the Integrated Agroecological Production System, in Rio de Janeiro State, Brazil, to evaluate the performance of cabbage–radish intercropping under organic management on the basis of agronomic traits and Area Equivalency Index (AEI). The contribution of green
manure pre-planting to the system also was evaluated. A randomized complete blocks design with seven replicates in a 2x3 split-plot factorial scheme was used. Treatments in the main plots consisted of Crotalaria juncea pre-planting or fallow. Cabbage or radish single crops and the respective intercropping were distributed in the subplots. No significant differences were detected between C. juncea
and fallow as related to cabbage or radish yields in any of the systems used (single crops and intercropping). Intercropping had no effect on cabbage yield, but significantly reduced radish root yield. However, commercial standard of the harvested radish roots was
not affected. An average AEI of 1,59 for the two experimental years was attained, thus indicating the viability of the cabbage-radish intercropping. The system makes possible to afford additional income for a given area cultivated with cabbage, at its conventional singlecrop
spacing, by including radish as a secondary crop. Intercropping also was advantageous by allowing optimization of cultural practices such as fertilization, weeding, and irrigation.
