Summary
Field experiments were conducted during the two successive seasons of 2005/2006 and 2006/2007 at the experimental agriculture station at Nobaria region Behara Governorate. The aim of these experiments were to study the influence of two nitrogen fertilization rates i.e. low (90 units/fed.) and high (120 units/fed.) as soil dressing as well as the foliar spraying of some organic acid (Gibberlic, Citric and Naphythyacetic acids) as promotion substances on the plant growth, yield and its physical and chemical properties of onion bulbs. The important obtained results are as following: Nitrogen fertilization of onion plant enhanced plant growth characters as expressed by plant length, fresh\n and dry weight of whole plant and its different organs, if added at higher rate (120 units/fed.). The total\n bulbs yield as ton/fed. as well as its physical properties followed the same pattern of changes. However, the application of higher nitrogen dose gained 0.672-1.228 tons more than lower dose. Generally, the nutritional values of onion tissues recorded higher constituents when nitrogen applied at higher rate. Foliar spraying of organic acids gained an enhancement in onion plant growth characters if compared with the checked plants. Moreover, using gebrrillic acid (50 ppm) and/or Naphythyacetic acids (500 ppm) as foliar application 3 times at fortnightly intervals gave the best plant growth measurements. Also, onion bulbs yield and its physical and nutritional values followed the same pattern.\n The interaction within the two rates of nitrogen fertilizer and foliar spraying of 3 organic acids as promoter substances had no statistical significant effect on the plant growth, bulbs yield as well as the quality of onion yield.
