Influence of homeopathic medicines and preparations in the development of lettuce seedlings

Abstract

The aim of this research was to investigate the influence of different potencies of homeopathic medicines Arnica montana, Calcaria carbonica, Carbo vegetabilis, Silicea terra, Phosphorus, Pulsatilla nigricans and the homeopathic preparation of Acai waste in the development of lettuce cultivar 'Veronica'. The experiment was conducted in a greenhouse at the Agricultural Experiment Unit of the Federal University of Acre at Campus Rio Branco, and followed the method adapted from Rossi. The development variables studied were: number of leaves (NF), height (ALT), root system length (CR), shoot dry weight (MSPA), dry root weight (MSR), stem diameter (DC), Dickson Quality Index (IQD) and the number of plants grown in the field 15 days after the transplant. The experimental design was completely randomized with four repetitions. The cultivar of crisped-type lettuce 'Veronica' was chosen for the test. The treatments were composed of homeopathic medicines Arnica montana, Calcaria carbonica, Carbo vegetabilis, Silicea terra, Phosphorus, Pulsatilla nigricans and the homeopathic preparation of Acai waste, the powers 6CH, 12CH and 30CH, and two witnesses, alcohol 30 %, which is the vehicle preparation of homeopathy, and water. Seedlings were obtained by seeding in polystyrene trays with 128 cells and the substratum used of the Subras® Company. The comparison between the means was performed by Scott-Knott test at 5 %. In the development of analysis it was observed that in almost all parameters evaluated the medicine Carbo vegetabillis 6CH, followed by Calcarea carbonica 12CH, Silicea terra 12CH, Phosphorus 12CH, Pulsatilla nigricans 12CH and the preparation of Acai 12CH contributed to a better performance of the seedlings.
