Resumo
O presente trabalho teve como objetivo avaliar a influência dos diversos ritmos da Lua (sinódico, sideral, anomalístico, tropical e draconiano) sobre o rendimento, a qualidade e a conservação pós-colheita de cenoura, quando semeada em diferentes datas, sob as mesmas condições de manejo, em uma propriedade familiar com manejo biodinâmico no município de Botucatu-SP. O delineamento experimental utilizado foi o de blocos ao acaso com 31 tratamentos em 2005, e 14 tratamentos em 2006. A diferença entre tratamentos foi a data de semeadura, que variou de 5 de maio a 4 de junho em 2005, e de 25 de abril a 25 de maio em 2006, sempre entre 13 e 15hs. A colheita foi feita 82 dias depois de cada semeadura, equivalente a três ciclos da lua sideral, e no ponto que o consumidor de produtos orgânicos e biodinâmicos valoriza, segundo experiência do produtor. Para retirar o efeito da tendência dos dados na avaliação dos tratamentos, foi utilizada a metodologia de avaliação estatística do cálculo do Índice Estacional (IE). Foram avaliadas as seguintes características: massa fresca de raízes e folhas, massa seca, diâmetro, comprimento, teor de nitrogênio, fósforo e boro das raízes e perecibilidade das raízes com 30, 60 e 90 dias póscolheita. Nos dois períodos avaliados, a massa seca de raízes foi a única que, no contraste entre médias, apresentou diferença significativa nos ritmos sinódico tradicional e sinódico caboclo. No ritmo sinódico tradicional, a fase nova foi superior às fases crescente e cheia. No sinódico caboclo, a fase cheia foi inferior às demais. No contraste entre médias, o ritmo sinódico foi o que mais apresentou resultados significativos, e em menor proporção, os ritmos anomalístico, draconiano e sideral; O ritmo tropical (ascendente X descendente) e teor de nitrogênio não apresentaram resultados significativos...
The purpose of this work was to evaluate the influence of moon rhythms (synodic, sidereal, anomalistic, tropical and draconic) on yield, quality and postharvest storage of Daucus carota L. roots under biodynamic management sowed in different dates. The experiment was carried out over a two period on a biodynamic farm, in Botucatu, São Paulo State, Brazil. Rhythms were tested observing the effects of seeding at different planting dates. The experiment was performed with four randomized blocks and 31 treatments (different dates) in 2005 and fourteen treatments in 2006. The harvest occurred 82 days after the sowing, when carrot roots show the most desirable aspect for the organic and biodynamic consumers. The magnitudes of effects associated with planting at a specific lunar position were measured by the deviations from the trend curve. The following characteristics were evaluated: fresh mass of roots and leaves, dry mass, diameter, length, nitrogen, phosphorus and boron content of the roots and perishability of the roots at 30, 60 and 90 days post-harvest. Dry mass was the only one that in the contrast between averages showed significant results in the two periods of the experiment. Result was that the synodic new phase was superior to the first quarter, and full phases and in the caboclo synodic rhythm, the full phase was inferior to the other. It was clear that the synodic caboclo rhythm had the most significant influence followed by the traditional synodic one. The draconic, sideral and anomalistic had less influence and the tropical rhythm had no influence at all considering studied aspects. Nitrogen and tropical rhythm did not present any lunar influence. The two evaluated periods are still not conclusive related... (Complete abstract click electronic access below)
