“…For this reason, eight basic unit plot sizes estimated by the modified maximum curvature is the one to be used for experiments on forage cactus pear (Guimarães et al, 2019). Paludo et al (2015) further explained that the modified maximum curvature method, despite its algebraic precision at determining the optimum plot size, estimates smaller plot sizes than other estimating methods, but with a better R 2 . Additionally, this method allows estimating intermediate plot sizes in comparison with pre-established basic unit plot sizes (Facco et al, 2018).…”

The optimum plot size for ‘Gigante’ cactus pear can be estimated by several methods; thus, ultimately aiming for efficiency, simple use and high precision, the objective of this study was to compare methods for estimating plot sizes: modified maximum curvature method, Hatheway’s convenient plot size method, linear and quadratic response plateau models, and comparison of variances method for evaluating phenotypic characteristics in experiments with ‘Gigante’ cactus pear. Plot sizes were estimated by conducting a uniformity trial. Estimated optimum plot sizes varied with the method and vegetative characteristic. The quadratic response plateau regression estimated the largest plot sizes, whereas Hatheway’s method estimated the smallest plot sizes. Comparison of variances method estimated intermediate plot sizes in comparison with the other methods for most measured characteristics. Plots sizes estimated by modified maximum curvature method are more consistent with results reported by studies on ‘Gigante’ cactus pear. 10 basic unit plot sizes estimated by the linear response plateau model can be used with high precision and practical feasibility for growing cactus pear, thereby improving the use of resources.

“…Diferentes resultados fueron obtenidos en estudios de tamaño de parcela en los diversos cultivos ya sean anuales o perennes. Por ejemplo: en ensayos con frijol (Smiderle et al, 2014) utilizo 60 plantas; en experimentos in vitro, 12 plantas, (Morais et al, 2014); en estudios con mucuna, 16 plantas, equivalentes a 8m² de área útil (Cagnelutti Filho et al, 2014); en experimentos con girasol, seis plantas, (Sousa et al, 2015); en ensayos con mamón, ocho plantas, (Paludo et al, 2015). Tal diferencia de tamaños ocurre en razón de los distintos cultivos estudiados, asi como las diversas características consideradas en los análisis y en los diferentes métodos de estimación utilizados.…”

Con el objetivo de determinar el tamaño adecuado de parcela en experimento con lechuga variedad veneranda conducido en el sistema hidropónico NFT fue montado un experimento en la ciudad de San Lorenzo – PY, en coordenadas coordenadas geográficas 25°19′59″S y 57°31′59″O. El experimento se desarrolló entre los meses de agosto a octubre del 2020, y fue conducido en un ensayo de uniformidad cuya población estuvo compuesta por 100 plantas de lechuga, variedad veneranda. La primera etapa del cultivo se realizó en la mesa de maternidad, para las siguientes etapas del cultivo se montaron caños con medidas específicas para cada etapa (intermedia, 10 caños de 50mm, y final, 10 caños de 75mm de diámetro). Cada caño, en cada etapa, alojo 10 plantas. La conductividad eléctrica vario según el estadio de desarrollo de la planta, etapa inicial 0,8 micro Siemens/cm (µS/cm), etapa intermedia 1,3(µS/cm) y etapa final 1.8µS/cm. La variable analizada fue: el peso individual de las lechugas; posteriormente, vía modelo lineal segmentado con respuesta plato se determinó que el tamaño adecuado de parcela en experimento con lechuga variedad Veneranda en sistema cerrado NFT es 0,52m² de área o siete plantas. En base a lo expuesto se recomienda, en parcelas experimentales con lechuga var. Veneranda, utilizar siete plantas en cada unidad experimental básica y realizar nuevas estimaciónes en caso de utilizar diferente variedad o sistema de producción.

Optimal plot size estimation in field experiment with purple passion fruit

The species P. edulis Sims f. edulis, native to Brazil, known as purple passion fruit, has purple fruits and lower acidity. With the growing demand for passion fruits, there is greater need for research on their cultivation to reduce production costs and improve fruit quality. The adequate determination of the size and number of plots has been a fundamental limitation in studies with several crops, as it is difficult to obtain constant data on plants per plot in most experiments, making it impossible to use usual methodologies for data analysis. As a result, testing can be performed with less labor and implementation costs, making plot size optimization a step of interest. Thus, this work aims to determine the ideal size of experimental plots with purple passion fruit in the field using three methods. The variables analyzed were fruit length, fruit diameter, peel thickness, juice yield, soluble solids content, citric acid, number of fruits, and average fruit weight. The use of optimal plot size of six basic units for fruit-related variables, five for pulp-related variables, and seven basic units for production variables, is recommended.
