In order to investigation the effects of different fertilizing levels on qualitative and quantitative yield of sweet corn, an experiment was conducted as randomized complete block design with three replications in 2012 at Marvdasht, Fars province, Iran. Experimental treatments were including different fertilizer sources 1) 200 kg ha-1 pure nitrogen, 2) 300 kg ha-1 pure nitrogen, 3) 8 ton ha-1 poultry manure, 4) 24 ton ha-1 solid waste compost, 5) 150 kg pure nitrogen + 2 ton poultry manure per, 6) 100 kg pure nitrogen + 4 ton poultry manure, 7) 150 kg pure nitrogen + 6 ton solid waste compost, 8) 100 kg pure nitrogen + 12 ton solid waste compost and 9) control (non-fertilizer). The results indicated that the effects of different fertilizing levels were significant on grain canned yield, fresh forage, biological, plant height, length and diameter ear as well as nitrogen, phosphorus and potassium content of grain. The heights grain canned yield (931 grm-2), fresh forage (2376 grm-2) and biological (4554 grm-2) was obtained from 100 kg pure nitrogen + 4 ton poultry manure treatment. Also maximum nitrogen content (2.27 percent) and phosphorus (0.42 percent) was observed at 300 kg ha-1 pure nitrogen and 8 ton ha-1 poultry manure treatment, respectively. The use of organic fertilizer as integrated with chemical fertilizer can be suitable method for decreasing application of chemical fertilizer to increasing the quantity yield and improvement the quality of sweet corn.
