ZARATE, Néstor Antonio Heredia et al. Yield of 'Chinês' taro in monocrop system and intercropped with chicory. Ciênc. agrotec. [online]. 2007, vol.31, n.5, pp. 1558-1562. ISSN 1981-1829. http://dx.doi.org/10.1590/S1413-70542007000500043.
The present work had the aim of evaluating the yield and gross income of 'Chinês' taro that was carried out in monocrop and intercropped system with 'Escarola Lisa' chicory in environment conditions in Dourados-MS. Treatments were arranged in a randomized experimental block design with five replications. Chicory harvest was done at 97 days after sowing and taro harvest at 203 days. Intercropping was evaluated by Land Equivalent Ratio (LER) and its validation was done determining gross income. Plants of taro and chicory were significantly influenced by means of cultivation, except to height of chicory plants that were similar. Monocrop system induced the highest yields of taro (9.90; 3.96; 10.42 and 9.03 t ha-1 of leaves, corms, commercial and non-commercial cormels, respectively) and greatest diameter (19.22 cm) and number (50.69 thousand ha-1) of commercial heads of chicory. LER for taro/chicory intercrop was 0.92 and, because of that, it was considered as non-effective.
