Abstract

ALVAREZ-HERRERA, Javier Giovanni; CHACON PARDO, Edinson  and  LUSARDO RODRIGUEZ, Santos. EFFECT OF TWO SUBSTRATES AND DIFFERENT IRRIGATION LEVELS IN THE PROPAGATION OF ROSEMARY (Rosmarinus officinalis L.). rev.udcaactual.divulg.cient. [online]. 2008, vol.11, n.1, pp.103-111. ISSN 0123-4226.

SUMMARY Little information on irrigation and substrates in nurseries for rosemary propagation under greenhouse conditions, that allows the producer to obtain the total productive capacity of the plant, is available. Under stress conditions the rosemary plant limits the production of dry and fresh biomass. The present work was carriet out with the objective to evaluate the effect of two substrates and different irrigation levels in the propagation of this aromatic plant. An completely random experimental design with ten treatments, product of the combination of five irrigation levels (multiplying coefficients of evapotranspiration 0.6, 0.8, 1, 12, and 1.4) and two substrates, black soil (BS) and the mixture of BS and burned rice husk (BRH), proportion 1:1, were applied, each treatment with four replica for a total of 40 experimental units (UE). The best coefficient (irrigation levels) for the propagation of cuttings was found to be number one. The best substrate for the propagation of rosemary was the mixture of black soil with rice husk in a proportion in volume of 1:1. The substrate BRH showed a higher efficiency in water use than the black soil obtained from moor. A higher water availability generated greater branch length. Higher production of fresh and dry biomass was obtained with the application of the coefficient of irrigation number 1 and the substrate BRH.

Keywords : Greenhouse; aromatic plants; rice husk; efficiency; evaporation.
