EFFECT OF DIFFERENT SOWING DATES ON TIMING OF BRUSSELS SPROUTS

The effect of three sowing times (1-beginning of April, 2-middle of April and 3-beginning of May) and three harvesting times (from the middle of October in one month intervals) on yield and quality of Brussels sprouts cultivars of various earliness was investigated in field conditions.
Earliest sowing as compared to the latest one increased the processing yield of mid-late cultivars up to 80 percent.
A four or eight weeks delay in harvest time of mid-late cultivars did not increase the number of overgrown sprouts (with diameter above 30 mm), what in consequence would lead to decrease of processing yield.
This positive effect of early sowing was not observed in yield of early cultivars, where delay in harvest time led to decrease of processing yield due to a greater number of overgrown sprouts.
The results show that in conditions of Poland mid-late cultivars may produce high processing yield when sown for transplants in the beginning of April.
