Cultivo de lavanda (Lavandula angustifolia) em diferentes substratos

Abstract

Lavender (Lavandula angustifolia) belongs to the family Lamiaceae and originates in the Mediterranean from where it began to expand to Spain and Portugal. In the last decades, it has gained prominence in the areas of gardening, decoration, aromatherapy and even cooking. However, there is little information on the ideal type of substrate for its cultivation, so the objective of the present study was to evaluate different substrates in the cultivation of lavender in pots in a protected environment. The experiment was conducted in a greenhouse where different formulations of substrates were used. In the treatment 1: 100% Mecplant, treatment 2: 80% Mecplant + 5% earthworm humus + 10% carbonized rice husk + 5% tanned bovine manure, treatment 3: 80% Mecplant + 10% earthworm humus + 5% % carbonized rice husk + 5% tanned bovine manure, and in the treatment 4: 80% Mecplant + 5% earthworm humus + 5% charcoal rice husk + 10% tanned bovine manure in pots with a capacity of 500 ml. The evaluated variables were plant height, number of leaves, and number of branches. The different substrates did not interfere in the development of lavender.
