OLIVEIRA, Eliane Q. de et al. Yield and agroeconomic values through intercropping of coriander and lettuce cultivars. Hortic. Bras. [online]. 2005, vol.23, n.2, pp. 285-289. ISSN 0102-0536. http://dx.doi.org/10.1590/S0102-05362005000200024.
The experiment was carried from October to December 2003, in the field, to evaluate the production and agrieconomic performance of coriander cultivars intercropped with lettuce cultivars. The experimental design was of randomized complete blocks in a 5 x 2 factorial scheme, with three replications. The treatments consisted of the combination of five coriander cultivars (Verdão, Superia, Português, Asteca and Santo) with two lettuce cultivars (Tainá and Babá de Verão). Evaluations of plant height, number of stalks/plant, shoot dry matter, number of marketable bunches/m2 and estimated yield of green mass were made from the coriander crop. Plant height and diameter, number of leaves/plant, leaf dry matter and estimate yield were obtained from the lettuce crop. Agrieconomic indicators were used to measure the efficiency of intercropping systems. There was a significant interaction between coriander and lettuce cultivars on plant height, number of marketable bunches/m2 and green mass estimated yield, with coriander cv. Português presenting the best performance in yield, in combination with both lettuce cultivars. The lettuce cultivars presented different yield performance, with lettuce cv. Babá de Verão being the most productive. Agrieconomic efficiencies were observed in all intercropping systems, but the highest efficiencies were registered in the combination of 'Tainá'/'Asteca' and 'Babá de Verão'/ 'Português'.
