TRATAMENTO HOMEOPÁTICO PARA MITIGAÇÃO DO ESTRESSE HÍDRICO NA GERMINAÇÃO DE AVEIA PRETA (Avena strigosa Sherb)

The use of chemosynthetic inputs in agriculture has caused risks to human, animal and environmental health. Therefore, it is necessary to rethink the model of agriculture practiced today with the intensive use of inputs with high environmental impact. Homeopathy has a promising potential for use in agriculture and livestock. This study aimed to select the homeopathic treatment and further evaluate its use in mitigating water stress in seeds of two black oat cultivars (Avena strigosa Schreb). The homeopatic treatment Calcarea carbonica was selected by homeopathic repertorization and used in the 7CH potency. The seeds were subjected to two tests: germination under four different levels of water stress, 0 MPa, -0.2 MPa, -0.4MPa and -0.8MPa and, electrical conductivity, with and without Calcarea carbonica application. The tests were evaluated for germination rate and electrical conductivity results. The best water stress mitigation results were obtained for the germination test at the levels of osmotic stress  pressure of -0.2 and -0.4 MPa for the cultivar IAPAR CABOCLA.
