ABSTRACT:      The use of agro-industrial waste may represent an alternative to reduce the costs of purchasing commercial substrates by producers of passion fruit seedlings, and carnaúba palm bagana is an alternative for the Northeastern Brazilian region. In this context, the objective was to evaluate the production of yellow passion fruit seedlings in substrates based on carnaúba bagana in different proportions with soil. The experiment was conducted in the experimental area of the Agrometeorological Station of Fortaleza, Pici Campus, Federal University of Ceará, Brazil, in a completely randomized design, whose treatments consisted of substrates formulated from the combination of different proportions of carnaúba bagana (CB) and soil: Soil (100%) + CB (0%); Soil (75%) + CB (25%); Soil (50%) + CB (50%); Soil (25%) + CB (75%); and Soil (0%) + CB (100%). The presence of CB, regardless of its proportion in the substrate, leads to the best results in photosynthesis and Dickson quality index (DQI) in yellow passion fruit seedlings. The best morphological responses were obtained with CB proportions greater than 50%, which also led to greater accumulation of nutrients in the shoots.

RESUMO:       O  emprego  de  resíduos  agroindustriais  pode  representar  uma  alternativa  para  diminuir  os  custos  de  aquisição  de  substratos comerciais pelos produtores de mudas de maracujazeiro, sendo a bagana de carnaúba uma alternativa para a região do  Nordeste  brasileiro.  Nesse  contexto,  objetivou-se  avaliar  a  produção  de  mudas  de  maracujazeiro-amarelo  em  substratos  à  base  de  bagana  de  carnaúba  em  diferentes  proporções  com  o  solo.  O  experimento  foi  conduzido  na  área  experimental  da  Estação Agrometeorológica de Fortaleza, Campus do Pici, Universidade Federal do Ceará, Brasil, em delineamento inteiramente casualizado, cujo os tratamentos foram constituídos por substratos formulados a partir da combinação de diferentes proporções de  bagana  de  carnaúba  (BC)  e  solo:  Solo  (100%)  +  BC  (0%);  Solo  (75%)  +  BC  (25%);  Solo  (50%)  +  BC  (50%);  Solo  (25%)  +  BC  (75%);  e  Solo  (0%)  +  BC  (100%).  A  presença  de  BC,  independentemente  de  sua  proporção  no  substrato,  apresenta  os  melhores  resultados  na  fotossíntese  e  no  índice  de  qualidade  de  Dickson  (IQD)  em  mudas  de  maracujazeiro  amarelo.  As  melhores respostas morfológicas foram obtidas nas proporções maiores que 50% de BC, que levou também ao maior acúmulo de nutrientes na parte aérea.
