Abstract
This investigation was conducted at the experimental station of the
Faculty of Agriculture, Cairo University, Giza, during the two successive
winter seasons of 2013/2014 and 2014/2015 to study the effect of three
planting dates, three F1 cultivars and their interactions on growth, yield and
quality of broccoli plants. The planting dates were as follows, 1st September,
1st October and 1st November with three F1 cultivars, viz. Marathon,
Heraklion and Centauro, respectively. Results showed that plant growth,
yield and quality of heads were greatly affected by the three cultivars in
planting dates. In this respect, second planting date 1st October gave the
highest values of most vegetative growth traits expressed as number of
leaves, leaf area and total fresh weight plant. As well as the highest values of
main head and total heads yield/plot and /fed. Plants gave the highest values
of most of vegetative growth characteristics, yield and quality of broccoli
followed by Marathon plus 1st November planting date recorded the lowest
values of growth, yield and its components. With respect to the interaction,
Centauro plus 1st October planting date was superior in total head yield and
physical characteristics of heads expressed as average head length, diameter
and weight. Therefore, it could be recommended for to obtain the highest
values of head yield and quality of broccoli we are advised to plant Centauro
and Marathon, respectively in planting date 1st October.
