Abstract
O objetivo deste trabalho foi estimar a forma e o tamanho de parcela ótimos para ensaios com a cultura do morangueiro (Fragaria x ananassa) em cultivo hidropônico e em solo. Foram conduzidos dois, experimentos, um em cultivo convencional no solo, em túneis baixos, e outro em cultivo hidropônico. Em cada experimento, avaliaram-se os efeitos do tamanho e do formato das parcelas sobre a precisão experimental. Cada planta foi considerada uma unidade básica, e o número de unidades básicas por parcela variou de 1 (48 parcelas) a 24 (duas parcelas). Foram ajustadas funções para a determinação do coeficiente de variação entre as parcelas e para a determinação da variância por unidade básica entre as parcelas. O cultivo no solo apresentou maior variabilidade experimental que o cultivo hidropônico. O aumento no número de plantas por parcela causou redução acentuada na variabilidade experimental, especialmente quando se usou o formato de parcela retangular. O tamanho ótimo estimado das parcelas é de dez plantas, no cultivo com solo, e de seis plantas, no cultivo hidropônico.
The objective of this work was to estimate the optimal size and shape of plots to be used in experiments of strawberry (Fragaria x ananassa) cultivation in soil or using hydroponics. Two experiments were conducted, one in soil in low tunnels, and another in a hydroponic system. In each experiment, the effects of plot sizes and shapes on experimental accuracy were evaluated. Each plant was considered an experimental basic unit, and the number of plants per plot varied from 1 (48 plots) to 24 (two plots). Functions were adjusted to determine the coefficient of variation among plots and the variance per basic unit between plots. Plants grown in soil had higher experimental variability than the plants grown in hydroponics. Increasing the number of plants per plot caused strong reduction in the experimental variability, especially when a rectangular plot shape was used. The optimal estimated plot size was ten plants in soil and six plants in the hydroponic system.
