Resumo

The objective of this work was to evaluate the effect of different concentrations of Spirulina platensis on the pro­duction of papaya (Carica papaya L.) seedlings in a protected environment. A completely randomized design (CRD) with five treatments and four replications was used, with five plants in the experimental unit (n=20). The treatments consisted of different concentrations of Spirufert®, class "A" simple organic fertilizer, brand Tamanduá. Concentrations of 0, 1, 2, 3 and 4% were used, diluted in drinking water. Growth characteristics, biomass accu­mulation and physiological aspects of the seedlings were evaluated using analysis of variance and, in the cases of significant effect, regression analysis was performed. The use of Spirulina platensis (Spirufert®) in low concentrations (1%) provided an improvement in the productive performance of the papaya seedlings and influenced the variable water use efficiency (A/E) in papaya seedlings.
