Abstract

SILVA, I.M. et al. Stem rooting of basil in different substrates and doses of ash. Rev. bras. plantas med. [online]. 2012, vol.14, n.spe, pp. 188-191. ISSN 1516-0572.  http://dx.doi.org/10.1590/S1516-05722012000500011.

The study aimed to evaluate the influence of ash doses on different substrates on the stem rooting of basil (Ocimum basilicum). The experiment was conducted in the area of core training and research at the Universidade Federal Rural da Amazônia, in Belém, used a completely randomized design, factorial scheme 2 x 5 consisting of the combinations of the factors substrate (carbonized rice husk and bark brown ground) and increase  ash (5 mL and 10 mL of rice husk ash 5 mL and 10 mL of husk ash and brown bark  no gray) with four repetitions. Each experimental unit consisted of 10 cuttings, a total of 400 cuttings.  Was evaluated the characteristics percentage of rooting, number and length of roots. There was no significant interaction between the factors evaluated (substrate and ash). Among the characteristics evaluated the carbonized rice showed only differences in root length and root number, while the levels of ash showed  only differences in rooting percentage. The study revealed that the dosages of ash had a positive effect on rooting of cuttings of basil, as well as the substrate prepared with rice hulls provided the best conditions for root development. Thus, the rice husk is an alternative, as well as presenting features suitable for rooting also has a low cost of acquisition, being within reach of many producers.
