A filed trial was conducted during the two successive seasons of 2007/2008 and 2008/2009 in the Experimental Farm at Demo (reclaimed soil with salinity at 7.84 and 8.01 dSm-1 in the two seasons, respectively), Faculty of Agriculture, Fayoum University to investigate the influence of farmyard manure soil application at the rates of 0, 10, 20 and 30m3 fed.- 1, ascorbic acid foliar application at the rates of 0,100, 200, 300 and 400mgl-1 and their combinations on the possibility of improving growth, yield of onion (Allium cepa L.) plants under the above mentioned conditions. In comparison with zero rate of farmyard manure, all other rates significantly increased vegetative growth characters (i. e. plant height, No. of leaves plant-1, leaves fresh weight plant-1, raw bulb fresh weight plant-1, total fresh weight plant-1, leaves dry weight plant-1, bulb dry weight plant-1 and total dry weight plant-1) total yield and some chemical constituents under study (i.e. total chlorophyll, total carotenoids, N, P and K of leaves and/or bulbs).
