manure and their integration on chemical soil properties and grain corn (Zea mays L.) yield, an experiment was conducted at the Agricultural Research farm of the Lorestan Weather Department, 30 Kms to the Northeast of Khorramabad, during 2003-2004. The experimental treatments included TO: control (lack of consuming integrated fertilizer and poultry manure); Tl: conventional (200, 100, 100 kg/ha of nitrogen, phosphorus, and potassium, respectively); T2: integration 1 (80% T1+ 4 ton/ha of poultry manure); T3: integration 2 (60% T1+ 8 ton/ha of poultry manure); T4: integration 3 (40% T1+ 12 ton/ha of poultry manure); T5: integration 4 (20% T1+ 16 ton/ha of poultry manure); T6: organic (20 ton/ha of poultry manure). The results suggested that fertilizer treatments have significant effects on the electrical conductivity, pH, organic matter, total nitrogen, available phosphorus and potassium of soil, and the number of ear seeds, 1000 seeds weight, corn grain and biological yield. The highest and lowest organic matter, total nitrogen, available phosphorus and potassium of soil were obtained by T6 and TO, respectively. The T5 treatment had the highest grain yield, with a significant difference from those of the TO, Tl, T3 and T6 treatments. Statistically, the difference between Tl (conventional nutrition system) and T6 (organic nutrition system) was not significant as well. Integrated poultry manure and chemical fertilizer effectiveness on corn yield components proved to be greater than that of each one on its own. As a result, the corn yield of integrated nutrition system is preferable to that of the chemical and organic ones.
