Abstract

BONILLA C, Carmen R; SANCHEZ O, Manuel S.  and  PERLAZA, Diego F. Evaluation of propagation methods, nitrogen fertilization and phenology in stevia in the Cauca Valley, Colombia. Acta Agron. [online]. 2007, vol.56, n.3, pp.131-134. ISSN 0120-2812.

This research was carried out at the Experimental Center of the National University of Colombia ( Palmira) in order to know more about the cropping system of Stevia rebaudiana Bertoni. The research consisted of an evaluation of rooting process and growth of cuttings from basal and apical position of the stem. The results were obtained from three root sustrates (coal ship-sand, coal ship-compost and sand-compost) and three different nitrogen sources (urea 46%N), compost 1.5% N and chicken manure 1% N). The results showed that the most productive sustrate was coal ship-sand 1:1 volume. The application of the nitrogen sources had no significant differences in accumulation of leaf dry matter. Phenological observation were as follows: emergence: 6 days after sowing (das), vegetative state: 17 das, flowering: 71 das, fructificatión: 115 das, senility: 169 das and shoot: 201 dís.

Keywords : sweet herb; propagation methods.
