Abstract: In order to determine the effect of farmyard manure (FYM), sulphur (S), humic acid (H) fertilization and their interactions on growth, chemical composition, yield and quality of onion plants cv.Italian Red, two experiments were conducting during 2013/2014 and 2014/2015 successive winter seasons at the Experimental Station of Agriculture College, Mansoura Univ., Egypt.The main obtained results could be summarized as follows: FYM addition at the rate of 20m 3 gave higher values than 10m 3 addition in all studied characteristics except crude fiber %, NO 3 -N (ppm) and bulb moisture% in both seasons.Sulphur fertilizer at 200kg/fed.caused superiority in the same studied parameters except crude fiber% , NO 3 -N ppm and bulb Moisture % in both seasons.Humic acid fertilizer at the rate of 15 kg /fed.achieved highest values comparing to other treatments in all estimated parameters in both seasons except crude fiber%, bulb moisture% in both seasons and NO 3 -N (ppm) in the second season.The interaction among 20m 3 FYM, 200kg/fed.sulpher and 15 Kg/fed.humic acid gave significant increases in dry weight (g/plant), plant height (cm), chlorophyll a+b (mg/g Fw), crude protein %, total carbohydrates%, TSS% , sulpher volatile oil% and total yield (t/fed.), but NO 3 -N (ppm) accumulation was decreased in both seasons.
