Resumo: | This study aimed to compare three methods of estimating the optimum plot size to evaluate the fresh matter productivity of pearl millet (Pennisetum glaucum L.), slender leaf rattlebox (Crotalaria ochroleuca), and showy rattlebox (Crotalaria spectabilis). Twenty-seven uniformity trials were carried out with pearl millet, slender leaf rattlebox, and showy rattlebox cultivated alone and intercropped. Fresh matter productivity was evaluated in 972 basic experimental units (BEU) of 1 m × 1 m (36 BEU per trial). The optimum plot size was determined using the methods modified maximum curvature, linear response with plateau model, and quadratic response with plateau model. The optimum plot size differs between methods and decreases in the following order: quadratic response with plateau model (9.94 m2), linear response with plateau model (7.41 m2), and modified maximum curvature (3.49 m2). The optimum plot size to evaluate the fresh matter productivity of pearl millet, slender leaf rattlebox, and showy rattlebox cultivated alone or intercropped is 7.41 m2. This size could be used as a reference for future experiments. |

Foram conduzidos 27 ensaios de uniformidade com milheto, crotalária ochroleuca e crotalária spectabilis, em cultivo solteiro e em consórcio. Foi avaliada a produtividade de matéria fresca em 972 unidades experimentais básicas (UEB) de 1 m × 1 m (36 UEB por ensaio). Foi determinado o tamanho ótimo de parcela por meio dos métodos da curvatura máxima modificado, do modelo linear de resposta com platô e do modelo quadrático de resposta com platô. O tamanho ótimo de parcela difere entre os métodos e decresce na seguinte ordem: modelo quadrático de resposta com platô (9,94 m2), modelo linear de resposta com platô (7,41 m2) e curvatura máxima modificado (3,49 m2). O tamanho ótimo de parcela para avaliar a produtividade de matéria fresca de milheto, crotalária ochroleuca e crotalária spectabilis, em cultivo solteiro ou em consórcio é de 7,41 m2. Esse tamanho pode ser utilizado como referência para futuros experimentos.
