In the years 1995-1997 a field experiment was conducted to assess the effect of different planting densities (50×20, 50×30, 50×40, 50×50 and 50×60 cm) on the yield of selected cultivars of broccoli (Sebastian, Cezar, Kermit F1 and Corvet F1).

It was found that the highest marketable yield and heads with the greatest weight and diameter were obtained in the case of cultivation of broccoli of cv. Kermit F1. The poorest yield was given by cv. Cezar. The study also revealed that the broccoli heads of cv. Kermit F1 and cv. Corvet F1 had more vitamin C and total sugars than those of cv. Sebastian and Cezar.

It was also found that yield of broccoli cultivars significantly increased with planting density row from 60 to 20 cm. However, with decreased planting density there was an increase in the weight and diameter of the main heads.
