A:PS

The experiment was carried out at FSRD siteKadamshaharGodagariRajshahi during 2009-10 and 2010-11 to find out the number of seed stalk and optimum boron dose for seed production of summer onion in High Barind Tract (AEZ 26). The treatments comprised three levels of seed stalk (04and 6) and three rates ofboron application (01and 2 kg/ha). Itrevealed that the seed stalks and boron either in single or combínation had significant effect on the yield and yield contributing characters of onion seed. The combinatìon comprising 4 stalks with 2 kg B/ha and 6 stalks with 1 kg B/ha were found to be the best choice for achieving higher seed yield of onìon. The highest seeded fruitlumbel (4.06 and 4.55) and seed yie1d (669 and 7日 kg/ha) were recorded from 6 stalks/plant ferti1ized with 1 kg boron/ha which was statistically identical to 6 stalks/plant fertìlized wìth 2 kg boronlha and 4 stalks/plant with 2 kg/ha boron ìn the High Barind Tract.
