MONDINO, M. C; BALABAN, D; CAVALIERI, O  e  GARCIA, S. M. Efecto de la cobertura de suelo con acolchados plásticos sobre el comportamiento del cultivo de alcaucil (Cynara cardunculus var. scolymus L.). FAVE. Secc. Cienc. agrar. [online]. 2017, vol.16, n.2, pp.61-67. ISSN 1666-7719.

The effect of black and bilayer polyethylenes on the behavior of the crop in Rosario area was evaluated. Madrigal hybrid was used and the evaluated variables were: Number of buds per plant, Weight first buds, Average weight Secondary buds, Total yield and per plant, Diameter first buds and average of secondary and Days to harvest. There were no significant differences between treatments. None of the coverages showed an advance in production. The use of plastic coverages in times of high temperatures in the evaluated area, is recommended to use not with the objective of obtaining production in advance but to facilitate the control of weeds and since the coverage with black plastic generates disadvantages, in the case of being necessary because of high presence of weeds, it would be advisable to use bilayer polyethylene.
