In order to study the effects of poultry manure and its incorporation systems with soil on grain nutrients cocentration of maize, a field experiment was conducted at the Ecological Research Center of Zagroos, 30 km from northeastern of Khorramabad for two consecutive years ( 2004 and 2005). Treatments were arranged in a split plots layout based on randomized complete block design with four replications. Two incorporation method of broiler litter incorporation with soil by furrower and disk+furrower as the main plot, and different amounts of broiler litter including zero, 10, 20, 30 Mg ha-1 as subplot were considered. The results suggested that the iron concentration of grain was much greater in the furrower treatment relative to the disk+furrower treatment. Averaged across years, maximum macronutrients and micronutrients concentration of grian were obtained by applying 30 Mg ha-1 broiler litter. However, no significant differences were found between 30 Mg ha-1 with 20 Mg ha-1 broiler litter for the nitrogen, phosphorus, manganese and cooper. The phosphorus, potassium, iron, and manganese concentration in grain for the second year was significantly greater than the first year. Thus, the incorporation of 20 Mg ha-1 broiler litter with furrower might be appropriate for increase of grain quality of maize under conditions similar to this experiment.
