Abstract

There is a large number of broccoli hybrid cultivars with different morphological traits and the length of the vegetation. Depending on the cultivation purpose of broccoli (top or lateral inflorescences) and use (fresh-market consumption of for processing), producers use different cultivars and plant densities. The aim of this research was to determine the effect of plant density, i.e. different spacing between rows, on the morphological characteristics and yield of broccoli hybrid cultivars in the spring-summer growing period.
Two plant densities: 60 x 50 cm (3.3 plants/m2) and 70 x 50 cm (2.8 b/m2) were tested. During the harvest period, basic morphometric values were determined: mass, diameter and yield of top inflorescence, length and diameter of stem. ‘Captain’ had the highest top inflorescence mass, diameter and yield (335 g, 12.5 cm and 10.3 t/ha) and the longest stem (7.6 cm). It also achieved the highest yield (10.8 t/ha) at the higher density (60 x 50 cm) due to the large number of plants per m2, while at 70 x 50 cm higher values of weight and morphometric traits were recorded.
