Use of different substrates in the production of organic seedlings of yellow passion fruit (Passiflora edulis)

Abstract

The objective of this study was to evaluate the use of two different substrates in the production
of yellow passion fruit (Passiflora edulis). The experiment was conducted in the experimental
area of Embrapa Agrobiology (Terraço) using the Natus Solos commercial substrate and substrate
prepared with subsoil, sand and manure from a corral, tanned in a ratio of 3: 1: 1. In the
production of the seedlings were used bags of black polyethylene with capacity of 500 g filled
with the substrates. The analyzed variables were: total size, number of internodes, internodes
size, number of leaves, number of tendrils. The data were evaluated by the Sisvar software.
Passion fruit seeds were extracted from fruits purchased in the popular market and sown in
a tray, presenting germination from the fifth day after sowing. At 10 DAE the seedlings were
transplanted to the polyethylene bags. After 45 days of transplantation, 20 random plants were
chosen from each treatment and the measurement was given. The analysis of variance (F Test
(p = 0.05) found that the prepared substrate induced superior performance in the development
of the seedlings compared to the commercial substrate.
