ABSTRACT:
The objective of this study was to determine the optimum plot size by sampling the total area and the fractions' areas in order to evaluate the mass and diameter of broccoli heads. In the field, 27 rows of hybrid BRO 68(r) were demarcated. Each plant was considered as an experimental basic unit (UEB). For analysis purposes, each row was regarded as being one blank test on 100 UEB. For the results of 27 rows yielded values: minimum, maximum, average, standard deviation, CV, confidence interval, the sample size (number of rows) to estimate Xo and to estimate the mean. The optimum plot size to evaluate the mass and diameter of broccoli heads equals five basic experimental units (plants).
Key words:
Brassica oleracea var. italica; spatial variation; sampling; experimental design.
