ZANETTI, Marcelo; CAZETTA, Jairo Osvaldo; MATTOS JUNIOR, Dirceu de  and  CARVALHO, Sérgio Alves de. The use of byproducts of vegetal charcoal on growth of 'Rangpur' lime rootstock under screen house. Rev. Bras. Frutic. [online]. 2003, vol.25, n.3, pp.508-512. ISSN 0100-2945.

The effect of finely grounded charcoal and pyroligneous acid (PA) in mixture with a commercial growing media and PA sprayed on leaves on growth of Rangpur lime (Citrus limonia Osbeck) seedlings under screen house was studied. Treatments consisted in a combination of 3 levels of charcoal (0, 100 and 200 cm3 dm-3) mixture on the commercial growing media, 2 rates of PA mixtured (0 and 20 cm3 dm-3) to a growing media (240 cm3 per dm3 of growing media), and 3 rates of PA (0, 5 and 10 cm3 dm-3) sprayed on the leaves, with 4 replications. The experiment was carried out in a randomized complete block design, and analyzed as a factorial 3 x 2 x 3. Growth of seedlings was evaluated at 150 and 180 days after planting. The presence of charcoal at 100 cm3 dm-3 in the media did not influence on growth of seedlings. However, the mixture with 200 cm3 dm-3 of charcoal reduced production of total dry mass and high of the plants. The addition of PA (solution 20 cm3 dm-3) to the media reduced plant growth, and sprayed (solutions 5 and 10 cm3 dm-3) on the leaves reduced seedlings diameter.
