- Abstract
SUMMARY Two varieties of tulip, Golden Harvest and Elmus, of selected bulb weight ranges, were grown in sand culture with different levels of nitrogen, phosphorus and potassium in factorial combination, and at different levels of magnesium. The effects of nitrogen were dominant, but the levels giving optimal bulb yields differed for the two varieties. Potassium and magnesium had smaller, but significant, effects and there were significant interactions between nitrogen and potassium. The weight distribution for all daughter bulbs produced from a single planting bulb was discontinuous in certain ranges. Nitrogen had an outstanding influence on the pattern of bulb multiplication, which also reflected a nitrogen/potassium interaction. Responses in weight distribution, as in total bulb production, showed both varietal and seasonal differences.
