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.
