Calculation of the ideal plot size for experiments using eucalyptus

Abstract

An adequate experimental planning depends on several factors, such as homogeneity of the area and experimental unity, number of repetition and plot size. The adoption of an ideal plot size reduces the experimental error and, consequently, maximizes the information obtained in an experiment. Thus, the aim of the present study was to calculate the optimal plot size of eucalyptus culture in a greenhouse, in order to optimize labor and costs in the cultivation process of this economically important culture. To calculate the optimal plot size, several simulations were performed using the modified maximum curvature method. Throughout the experimental period, clonal seedlings of the Eurograndis hybrid were used and evaluated for height (H), stem diameter at the base (DB), chlorophyll content in old leaves (Chlor V) and new leaves (Chlor N) at 30, 60, 90 and 120 days after seedling transplantation. After 120 days, the seedlings were collected to determine the dry mass of the aerial part (DMAP) and the root system (DMRS). Results indicated that the optimal recommended plot size for eucalyptus, in a greenhouse, were 6 plants per plot.

Determinação do tamanho ótimo de parcelas em experimentos com mudas de mamoeiro THB

“…A fim de obter o tamanho ótimo de parcela de experimentos pode encontrar descritos na literatura algumas metodologias, e dentre estas destaca-se pelo seu uso frequente, atualmente, a de máxima curvatura modificado, segundo Meier & Lessman (1971). Dentre os usos recentes da metodologia segundo Meier & Lessman (1971), citam-Brazilian Journal of Development, Curitiba, v.8, n.12, p. 79346-79356, dec., 2022 se o de Faria et al (2020), usado para determinar o tamanho ótimo de parcela de experimentos com maracujazeiro e por Lopes et al (2020) para experimentos com mudas de eucalipto em casa de vegetação.…”
