DOUGLAS MARIN, Ch  and  GUEDEZ, Yajaira. Comparative growth of Urena sinuate L., Plantago major L. and Zingiber officinale L. plants. Rev Cubana Plant Med [online]. 2006, vol.11, n.2, pp. 0-0. ISSN 1028-4796.

The growth of Urena sinuta L. (cadillo de perro), Plantago major L. (Plantain), and Zingiber oficinale L. (Ginger) plants cultivated in open-air beds in Maracay, Venezuela, was compared. The curves of accumulation of total dry matter and of the foliage area growth showed significantly high values in Z. officinale from the 50th day of its sowing on. The yieldings in dry matter accounted for 4.87, 1.91, and 1.81 t/ha in Z. officinale , U. sinuata and P. major . The leave fraction in U. sinuata , and P. major were 0.47, and 0.82 t/ha, respectively; whereas that of rhizome of Z. officinale was 2.04 t/ha. These results showed that the cultivation in beds is a simple way to produce medicinal plants in home environments. There were no differences in the values of growth relative rate among species, but they were certainly observed in their component variables.
