Efeito da solarização do solo associada à incorporação de materiais orgânicos dentro de sacos plásticos na incidência de patógenos radiculares e na produção de mudas de mamoeiro.

Abstract

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.
