- Abstract
The organic fertilization provides nutrients for the plants, improves the soil physical structure, increases the water retention, reduces the erosion losses and favors the biological control. Ocimum selloi is a native medicinal plant of south and southeast of Brazil where is used popularly as antidiarrhetic, antispasmodic and anti-inflammatory. This research aimed to verify the effect of different doses of two organic fertilizers souces in O. selloi growth, essential oil yield and chemical composition. The experiments were carried out in Lavras, MG, with pots in polyethylene greenhouse with two manuring treatments: Test A - Cattle manure: 1) Soil without manuring (control); 2) Soil + 3kg m-2 cattle manure; 3) Soil + 6kg m-2 cattle manure; 4) Soil + 9kg m-2 cattle manure; 5) Soil + 12kg m-2 cattle manure; Test B - Chicken manure: 1) Soil without manuring (control); 2) Soil + 1.5kg m-2 chicken manure; 3) Soil + 3 kg m-2 chicken manure; 4) Soil + 4.5kg m-2 chicken manure and 5) Soil + 6kg m-2 chicken manure. The influence of cattle and chicken manuring doses was verified on plant height, stem diameter, dry biomass weight, TLA, SLA, LWR, chlorophylls content, leaf thickness, essential oil yield and composition.
