Solarização e incorporação de materiais orgânicos vegetais para tratamento de substrato para produção de mudas de mamoeiro (Carica papaia L.).

Abstract

Aiming to check the effect of solarization and incorporation of organic plant matter on substrate plant for the production of papaya seedlings , apart from the occurrence of damping off an experiment was installed in the área of laboratories, the CCTA-UATAUFCG. Pombal-PB. The substrato was composed of a land área cultivated with passionfruit. whose plants had symptoms consistent with diseases caused by fungus in soir. In this soir. manure was added in proportion 3:1 and incorporated or otherwise of organic plant material (castor oil. cassava and neem-trem)l solarized or not, for a period of 15 to 30 days. The experimental design was applied with a completely randomized factorial 4x2x2 and 5 replicates totaling 16 combinations and 80 experimental units. It was evaluated the growth parameters such as: plant height, stem diameter. number of leaves and total dry weight. The analysis of variance revealed significant numbers for the parameters of leaves and stem diameter. The average test showed no difference for treatments not solarized, but among those who received the solarized organic matter plant, were higher than those not given Among the treatments that have not received vegetable organic matter. not the number of solarized had leaves and stem diameter greater than solarized. The time of treatment for a period of 30 days. provided the plants with larger diameters. During the conduct of the work lust only a change solarized showed symptom of damping off.
