Formulação e avaliação de substratos para a produção de plantas aromáticas envasadas em modo de produção biológica
| Resumo: | The main objective of this study was to develop a substrate for the production of aromatic plants in organic production from peat, coir and chicken manure. Coir was intended to replace in whole or in part peat, and chicken manure was the main function to provide nutrients for crop growth. In the first trial, it was found that the conductivity increased linearly with increasing amount of manure in mixtures based on peat or coir. In the second trial it was found that percentages of manure greater than 5% led to damage in vegetatively propagated plants. The seminally propagated plants were affected by all modalities containing manure. It was also found that modalities with coir originated worse results than modalities with peat. In the third trial, the mixtures included 5% of manure and different proportions of peat and coir. It was found that the substrates with 31.6% of coir, 63.3% of peat and 5% of chicken manure had the best results in the cultivation of plants. It was carried out a germination test with Lepidium sativum, which concluded that no substrate showed phytotoxicity |
