Excerpt from Effect of Storage, Bulb Size, Spacing, and Time of Planting on Production of Onion Seed The best temperature at which to store mother bulbs of a highly non bolting strain of Ebenezer was about 535 F. Plants from bulbs stored at this temperature bloomed and ripened their seed earlier, produced more seed stems and yielded more seed per acre than plants from mother bulbs stored at higher or lower temperatures. In a comparison of eight different Sizes of mother bulbs of the Yellow Globe Danvers variety ranging in weight from about 15 to 90 grams, there was found to be an increase in number of seed heads per plant, in seed yield per plant, and in seed yield per acre with each increase in Size of bulb. In spacing tests with the Yellow Globe Danvers variety, bulbs were set 3, 4, 6, 8, and 12 inches apart in a row. A significant increase in seed yield per plant was secured with each increase in spacing but a decrease in yield of seed per acre. When bulbs of Yellow Globe Danvers were planted at different dates throughout the winter there was a delay in time of seed maturity of the late-planted bulbs; and, accompanying this, a decrease in yield of seed.
