Resumo
Avaliou-se a produtividade das culturas de rabanete e alface, e a qualidade de seus produtos, em função da época de estabelecimento do consórcio, na UNESP em Jaboticabal, de março a maio de 1999. Os tratamentos foram constituídos por consórcios estabelecidos aos 0; 7 e 14 dias após o transplantio (DAT) da alface e monocultivos implantados nestas mesmas épocas. As cultivares de rabanete (Raphanus sativus L.) e alface (Lactuca sativa L.) utilizadas foram, respectivamente, Crimson Gigante e Carolina. Maior altura das plantas de rabanete foi observada quando consorciada com alface. As plantas de rabanete em monocultivo apresentaram acúmulo de massa seca da parte aérea (MSPA) 29,4% menor do que em consorciação, independente da época de semeadura. Para massa seca de raízes tuberosas, maior acúmulo foi obtido na presença de alface, independentemente da época de instalação do consórcio. Quanto a MSPA de alface, maior acúmulo ocorreu em consórcio, quando a semeadura do rabanete foi realizada até 7 DAT. Além de menor acúmulo de MSPA, quando a semeadura do rabanete foi realizada aos 14 DAT, a alface apresentou perda na qualidade comercial. O maior valor da razão de área equivalente (1,6) no sistema de consórcio, foi obtido quando o rabanete foi semeado aos 7 dias após o transplantio da alface.
The yield and quality of radish and lettuce were evaluated, taking into account the time of establishment of the intercropping. The experiment was carried out in the UNESP, Jaboticabal (Brazil). The treatments were made up of intercropping established at 0; 7, and 14 days after transplanting (DAT) of the lettuce and monocultures established in these same dates. The radish (Raphanus sativus L.) and lettuce (Lactuca sativa L.) cultivars were Crimson Gigante and Carolina, respectively. Taller radish plants were observed when intercropped with lettuce. Regardless of the sowing dates, radish plants in monoculture accumulated 29.4% less dry matter of the aerial part (DMAP) than in intercropping system. For dry matter of tuber roots, higher accumulation was obtained when intercropped with lettuce, regardless of the time of installation of the intercropping. Larger accumulation of lettuce DMAP was measured in intercropping system, when sowing of the radish was accomplished up to 7 DAT. Besides smaller accumulation of DMAP, when the sowing date of the radish was accomplished 14 DAT, there was a reduction in lettuce quality. The largest value in relation to the equivalent area (1.6) in the intercropping system was obtained for the radish sowed 7 days after the lettuce.
