| Resumo: |
The intercropping practice is a viable technological option for the production of vegetables and the success of the association between crops will be greater the greater the complementarity between them. The present work was conducted from June to November 2006, at Universidade Federal Rural do Semi-Árido, Rio Grande do Norte State, Brazil, to evaluate the productive performance of two lettuce and two rocket cultivars in two cultures in strip-intercropping systems. The experimental design was randomized complete blocks, with five replications and treatments arranged in a 2 x 2 + 2 factorial. The treatments consisted of the combination of two lettuce cultivars (Babá de Verão and Tainá) and two of rocket (Cultivada and Folha Larga) intercropped with carrot 'Brasília' plus two additional treatments (two lettuce cultivars or two rocket cultivars grown in sole crop). In each block a plot with carrot in sole crop was grown. The evaluated traits in lettuce were plant height and diameter, number of leaves per plant, productivity and shoot dry matter mass. In rocket were evaluated plant height, number of leaves per plant, green mass yield and shoot dry matter mass; and in carrot: plant height, total and marketable productivity, besides root classes, in long and medium roots, short roots and scrap roots. The Tainá lettuce cultivar had the best yield performance both in sole crop and intercropping system. The Cultivada and Folha Larga rocket cultivars had similar yield performance in both cropping systems. Both lettuce and rocket crops had better productive performance in the second culture. The mean production of carrot marketable roots in intercropping systems was 68.3%, being 48.6% for long and medium roots and 19.7% for short roots, while in the sole crop the mean production of marketable carrot roots was of 75.0%, being 51.7% for long and medium roots and 23.3% for short roots.
