Secondary Broccoli Production Depending On Sowing And Planting Dates

The investigation was carried out during the period of 2009-2011 at the Institute of Agriculture – Kyustendil, located in the Southwest Bulgaria. Four broccoli (Brassica oleracea var. italica Plenck) hybrids were grown by the technology of late field production with different sowing and planting dates. The aim of the research was to establish a relationship between planting time and secondary yield of broccoli. Some morphological characteristics and production traits of an additional yield of broccoli side shoots were studied. Different variants and hybrids formed from 395.0 to 1038.5 kg/da additional production during the years of the experiment. Fiesta F1 has the highest number of secondary flower heads per a plant (4.9), average for the period. The largest lateral flower heads formed hybrid Marathon F1 – 0.092 kg. Тhe secondary yield ranges from 18.6 to 33.1 % of total broccoli yield and can compensate the low yields obtained from primary head production
