Resumen:
This study aimed to evaluate soil solarization effect combined with organic material incorporation in plastic
bags in the soilborne plant pathogens incidence and papaya seedlings production. Two experiments were
conducted in different seasons (dry season and rainy season). The design was completely randomized in
factorial arrangement of 4x2x2, with five replications, consisting of organic matter incorporation (no organic
matter, castor, cassava and neem tree), solarization (with and without) and treatment period (15 and 30
days), respectively. It was found that the addition of castor associated with soil solarization, in the dry
season, higher values in the neck diameter, leaves number, plant height and shoot dry matter weight.
However, in the rainy season, the amount of cassava and neem tree, associated with soil solarization, higher
values in the neck diameter, leaves number, plant height and shoot dry matter weight. It was also found that
the best period for material incorporation (15 or 30 days), combined with soil solarization, varies according to
type of material used.
