RESUMO Em estudos experimentais, alcançar uma configuração ideal de parcela é de importância significativa. Objetivou-se estabelecer tamanhos de parcelas experimentais adequados para a avaliação de características agronômicas de mudas do clone LB1 de café conilon cultivadas em tubetes. Tanto as características não destrutivas quanto as destrutivas foram avaliadas a partir de mudas obtidas em viveiro, sendo cada muda alocada em unidades experimentais básicas. Utilizou-se delineamento de blocos inteiramente casualizados e vários cenários foram gerados com base em combinações de tratamentos (3, 4, 5, 6, 7, 8, 9, 10, 15, 20, 25, 30, 35 e 40), repetições (3, 4, 5, 6 e 7) e níveis de precisão experimental (10, 20, 30 e 40 %).

ABSTRACT In experimental studies, achieving an optimal plot configuration holds significant importance. This study aimed to establish suitable experimental plot sizes for evaluating agronomic traits of clone LB1 conilon coffee seedlings grown in tubes. Both non-destructive and destructive traits were evaluated using seedlings obtained from a nursery, with each seedling allocated to basic experimental units. A completely randomized block design was used and various scenarios were generated based on combinations of treatments (3, 4, 5, 6, 7, 8, 9, 10, 15, 20, 25, 30, 35 and 40), replicates (3, 4, 5, 6 and 7) and levels of experimental precision (10, 20, 30 and 40 %). Convenient plot size recommendations were obtained for clone LB1 conilon coffee seedlings grown in tubes. studies importance LB tubes nondestructive non nursery units 3, 3 (3 4 5 7 8 9 10 15 20 25 40, , 40) (10 %. % . %) ( 1 2 (1

ABSTRACT Apple cultivation in the tropical conditions in northern Espírito Santo state is recent and, to increase the cropped area, basic field experimentation research is still necessary. Thus, the objective of this work was to determine the optimal plot size (OPS) for experiments with apple plants that are not very demanding in cold conditions of the cultivars Eva, Julieta, and Princesa, based on the evaluation data of three characteristics, in northern Espirito Santo state. After three years and three months, the stem diameter, production in the number of fruits per plant, and mass production per plant were evaluated. To determine the OPS, two methods were used, the maximum curvature modified in its original form, and the maximum curvature modified with bootstrap simulation, both according to Meier and Lessman. The two methods presented similar results for each characteristic, however the productive characteristics presented higher OPS compared to the vegetative characteristic of stem diameter. When setting up field experiments with apple plants of the Eva, Julieta, and Princesa varieties in conditions in the north of the state of Espírito Santo, it is recommended to plan with six plants in each experimental plot. area necessary Thus (OPS Eva Julieta months diameter evaluated used form simulation Lessman
