Determinação do número de amostras e diagrama de amostragem para obtenção de dados biológicos em campos cultivados com mamoeiro.

Abstract

The correct sampling is prime for obtaining significant biological data for study of agricultural and forestalls ecosystems. The present study had as objective the evaluation of samples number and diagram pattern for collecting soil in order to monitor Meloidogyne sp. and Rotylenchulus sp. population density in papaya (Carica papaya) field. Twenty samples per area were indicated for both nematode genera, being recommended to collect the samples randomly, in parallel bars or in diamond diagrams for Meloidogyne sp. and in parallel lines or bars for Rotylenchulus sp.
