Formação de mudas de alface provenientes de sementes peletizadas com altas diluições

Abstract

ResumoA peletização de sementes vem sendo caracterizada como uma importante forma de maximização nos custos de produção de mudas pelo fato de reduzir o trabalho e mão de obra de distribuição manual de sementes, reduzindo ainda a prática do desbaste de plantas excedentes. No entanto, o interesse comercial pelo encapsulamento de semente avançou após a semeadura mecanizada, prática de plantio direto e, principalmente, pela possibilidade de inserção de nutrientes, reguladores de crescimento e aplicação de agrotóxicos como forma de constituir melhorias na sanidade das plantas. Nesse sentido, objetivou-se avaliar a produção de mudas de alface (Lactuca sativa L. c.v. Grand Rapids) oriundas de sementes peletizadas com preparados homeopáticos submetidas à cobertura de homeopatia de Phosphorus 30CH. Os resultados apontam que a utilização de homeopatia de Sulphur 6CH e Nux vomica 6CH são capazes de propiciar mudas sadias e vigorosas quando comparadas com a testemunha.Palavras-chave: agroecologia; homeopatia; Lactuca sativa L. AbstractThe seed pelleting has been characterized as an important way of maximizing the seedlings production costs because of lower labor and manpower manual seed distribution, while reducing the practice of surplus plants thinning. However, the commercial interest in seed encapsulation advanced after mechanized seeding, tillage practice and especially the possibility of inclusion of nutrients, growth regulators and pesticides application as a way to provide improvements in the health of plants. In this sense, the objective was to evaluate the production of lettuce seedlings (Lactuca sativa L. cv. Grand Rapids) arising from pelleted seeds with homeopathic

Physiological quality of pelleted Cubiu (Solanum sessiliflorum Dunal) seeds

“…In the last decades, this technique has been widely used in forest seeds, vegetables, leguminous and forage grasses (SIKHAO et al, 2015). It can also serve as a carrier for the incorporation of nutrients, inoculants, growth regulators and other agrochemicals (QUEIROZ et al, 2015).…”

Chamomile Cultivation Submitted to Ultra-diluted Phosphorus Solutions

“…Dilutions of Carbo vegetabilis (6CH), Silicea land (30CH) and Sulphur (30CH) promoted increase in the fresh and dry mass of broccoli inflorescences (Pulido et al, 2017), as did Phosphorus 30CH applied to seeds of lettuce (Lactuca sativa L.) (Queiroz et al, 2015). Some homeopathic medicines are used in the control of phytopathogenic microorganisms (Trebbi et al, 2016;Shah-Rossi et al, 2009), such as Berberis vulgaris in the control of rust, powdery mildew and downy mildew (Bonato, 2014), and Propolis (6CH, 12CH and 30CH) to minimize the severity of early blight in tomato (Toledo et al, 2015).…”
