High dilution preparations for organic production system of broccoli

Abstract

The aim of this study was to evaluate the influence of high dilution preparations on seedlings growth and production of broccoli under organic system. Three experiments were conducted in a greenhouse with completely randomized design. Two others experiments were conducted under field conditions, and the experimental design was randomized in blocks. Both designs were done with four replications and nine treatments. The treatments consisted of high dilution preparations of Arnica montana, Silicea terra, Carbo vegetabilis and Sulphur at 6CH or 30CH, water was used as control. In greenhouse, plant height, root length and stem diameter of seedlings were evaluated, along with the fresh and dry mass of shoot and root. In field, fresh and dry mass of inflorescences, plant heigh and stem diameter were evaluated. Silicea terra at 30CH increased the stem diameter, root length and dry mass of shoot and root in the broccoli seedlings. Sulphur at 6CH increased the fresh and dry mass of broccoli inflorescences. Silicea terra at 6CH, Carbo vegetabilis, and Sulphur at 30CH increased the plant height in field experiments. This suggests that high dilution preparations can be utilized to increase the biomass production and others desirable characteristics of broccoli crop under organic system.

Systemic Agro-Homeopathy: A New Approach to Agriculture

“…In this context, agro-homeopathy could be an integrative approach to improve organic agriculture since homeopathic treatments, due to their ultrahigh dilutions, have few or no ecological side effects. In recent years there has been a growing interest of the scientific community in such methods, and many scientific studies have been performed to evaluate the effect of homeopathic treatments on plants [1][2][3][4][5][6][7][8][9][10]. Different plant model systems have been set up both in basic research (in vitro germination and growth models with healthy, impaired, and phytopathological models) [1][2][3][4][5] and in application research (field trials) [2].…”

“…Different plant model systems have been set up both in basic research (in vitro germination and growth models with healthy, impaired, and phytopathological models) [1][2][3][4][5] and in application research (field trials) [2]. Experimental research on healthy and stressed plants has shown the potential of homeopathic treatments to influence plants by enhancing growth parameters, increasing germination rate and defensive substances, and strengthening plants against pathogen and pest attacks [6][7][8][9][10].…”

“…se ao controle de pragas, como pulgões (WYSS et al, 2010), fungos (TREBBI et al, 2016), incremento no teor de óleo essencial em menta (Mentha arvensis) (BONATO et al, 2009), acréscimo na massa fresca de brócolis (PULIDO et al, 2017) (v v -1 ). Para a aplicação nas plantas, o Phosphorus foi diluído em água destilada na proporção de 0,5 mL L -1 .…”

“…not exclusive to these systems (Brasil, 2014). Pulido et al (2017) demonstrated an increase in broccoli (Brassica oleraceae L. var. itálica) biomass through the use of Sulfur 6CH, Silicia terra 6CH, Carbo vegetalis 30CH and Sulfur 30CH.…”
