Use of ethephon (Ethrel) in onions grown for sets (cultivar Wolska) sown
in rates of 200, 150, 100, and 50 kg seeds per ha gave a high marketable
yield even at the lowest rate. The most favourable effect has been
obtained while treating onions with 1 dm3
Ethrel per ha 42 days after emergence. Higher doses of this chemical - 1.5
and 2 dm3/ha used both 42 and 56 days
after emergence decreased the marketable yield of onion sets, however, its
share in the total yield was increased.
