Resumo

Resíduos agrícolas podem ser transformados em fertilizantes orgânicos através da inoculação de microrganismos eficientes, que influenciam o crescimento das plantas, resistência a doenças e pragas, e estimulam as atividades fisiológicas. O objetivo principal deste estudo foi desenvolver um biofertilizante a partir de resíduos agrícolas utilizando fermentação anaeróbica, inoculado com Paenibacillus polymyxa e Trichoderma sp., para o cultivo de três cultivares de rabanete (Raphanus sativus L): Scarlet Champion, Crimson Giant e Reggae. O experimento seguiu um delineamento de blocos totalmente casualizados (DBCA) com 12 tratamentos e cinco repetições, totalizando 60 unidades experimentais. A mistura de inoculação consistia em 10% de biofertilizante, 89,65% de água de irrigação e 0,35% de P. polymyxa ou Trichoderma sp. A fertilização foi aplicada no solo aos 7, 12 e 17 dias após o plantio. As três cultivares de rabanete apresentaram maiores taxas de sobrevivência, altura das plantas, diâmetro dos bulbos, peso da folhagem e peso dos bulbos quando tratadas com o biofertilizante enriquecido com P. polymyxa, o que influenciou suas características morfológicas. Essa abordagem permite aos agricultores reduzir o uso de fertilizantes químicos, diminuir custos econômicos e desenvolver novos produtos biotecnológicos ambientalmente amigáveis. O biofertilizante enriquecido com P. polymyxa aprimorou significativamente a morfologia das plantas em todas as três cultivares de rabanete. O Crimson Giant alcançou uma taxa de sobrevivência de 100% durante a fertilização, com altura de planta de 26,49 cm aos 32 dias, diâmetro do bulbo de 4,78 cm, peso da folhagem de 0,81 kg e peso do bulbo de 46,00 g.
