Abstract

The planting density is a factor that affect the development, commercial inflorescence diameter and the yield of the processing broccoli. It has conducted in Cartaxo an experimental field, under normal growing conditions, to evaluate the effect of plant density in the spring broccoli, variety “Parthenon”.   Three planting densities were evaluated: D1-2,67 plants/m2 (0,50mx0,40m); D2-3,3 plants/m2 (0,40mx0,40m); D3-4,44 plants/m2 (0,30 x 0,40 m). The experimental field was installed in tottaly random plots with 4 replicates per treatment. The yield and the average diameter of heads per plant were estimated at the end of crop cycle.

The estimated average yield was higher in D1 and D2. The treatments affected the diameter and the average weight of inflorescences, being higher in D1 and D2. The planting density can be used to control the average size of the spring processing broccoli.
