APLICAÇÃO DE BIOINOCULANTES DE SOLO COMPOSTADO PARA PROMOÇÃO DO CRESCIMENTO DE RÚCULA (Eruca sativa), CENOURA (Daucus carota sativus) e RABANETE (Raphanus sativus)

Abstract

O objetivo do estudo foi avaliar a capacidade da inoculação com consórcio microbiano de promover o crescimento de rúcula, cenoura e rabanete. As sementes das hortaliças foram semeadas diretamente no canteiro e banhadas com inoculante microbiano ou com água destilada (controle). Amostras inoculadas tiveram um aumento no comprimento da raiz e da parte aérea, na largura e no número de folhas e na massa total fresca. Os resultados demostraram que o uso de inoculantes melhora o crescimento de rúcula, cenoura e rabanete, sendo uma alternativa sustentável na produção de hortaliças.

Agroecological Transformation: Implementation of an Agroforestry System in a Construction Debris Area Focusing on Vegetables Development through Microbial Treatments

“…The increase in the arugula shoot dry weight in 2.98 and 1.94 times in the first and second experiment of the present study corroborates with it. On the other hand, while Mira et al (2021) [13] related an increase in carrots biomass, the present results do not show that. Although the authors made just one application of the MC, it can be worthy to do another application in the middle of the growing period, since carrots takes a longer time to be harvested than arugula and lettuce.…”

“…The first trial with the microbial consortium used in this study was carried out by Mira et al (2021) [13]. The authors isolated the microbial consortium from compost and applied in arugula, carrots, and radish.…”

“…The experiment was conducted in a completely randomized blocks with five treatments: (C) Control; (CT) 0.5 L/ m 2 of vermicompost tea diluted in the proportion 1:15; (Ap) 0.5 L/ m 2 of Artrhospira platensis cultivated in CT; (MC) 0.5 L/ m 2 of microbial consortium obtained from compost (1.2 x 10 9 cells/mL) [13]; (Bk) 1.0 kg/ m 2 of Bokashi. Each block consisted of two rows of garden bed with 16 m 2 , each plot has 2 m of length spaced by 1 m length from each other, a space of 0.5 m of length in the ends of the garden beds was considered (Figure 1a).…”

“…Mira et al (2021) [13] isolated a microbial consortium from compost and inoculated in arugula, carrots, and radish obtaining great results on these three cultures. This microbial consortium differs from the conventional inoculants since it is inoculated a microbial community and not an isolated strain, it has potential to become a commercial inoculant, but more tests should be done.…”

“…We tested the efficacy of the microbial consortium presented by Mira et al (2021) [13] and the cyanobacteria Arthrospira platensis comparing with the application of the vermicompost tea and bokashi in arugula, lettuce, beetroot, and carrot in an agroforestry system implemented in an area that was used for construction debris deposit. Based on the literature and our previous pilot trials, we hypothesized that both the microbial consortium and A. platensis could show good results in vegetables development being potential for new inoculant development for horticulture.…”
