BARROS JUNIOR, Aurélio P. et al. Lettuce cultivation in low tunnels of agricultural textile. Hortic. Bras. [online]. 2004, vol.22, n.4, pp.801-803. ISSN 0102-0536.  http://dx.doi.org/10.1590/S0102-05362004000400028.

The yield of lettuce cultivated under low tunnels of agricultural textile was evaluated in Mossoró, Rio Grande do Norte State, Brazil. The experiment was carried out from March to April of 2004, in a randomized complete blocks design with three treatments and four replications. The treatments were: low tunnel (with 50 cm of height) of white agricultural textile with basic weight of 40 g/m2; low tunnel (with 50 cm of height) of white agricultural textile with basic weight of 13 g/m2 and control (treatment with no coverage). Evaluations of plant height and diameter, number of leaves per plant, shoot dry matter and yield were done. Cultivar Babá de Verão presented greater plant height, number of leaves per plant and yield. The low tunnel of agricultural textile with basic weight of 40 g/m2 presented superior results of plant height, diameter and yield.

Palavras-chave : Lactuca sativa L.; soil coverage; yield.
