In order to evaluate the effect of integrated plant nutrient management, an experiment was conducted with different fertilizer treatments in a randomized complete block design with six treatments in five replicates (each replicate contains a date palm tree) in Abadan during 2010-13. Treatments were mineral fertilizer, 50% of mineral fertilizer + organic fertilizer, 25% of mineral fertilizer + organic fertilizer + organic sulfur, 25% of mineral fertilizer + organic fertilizer + powdery sulfur, 25% of mineral fertilizer + organic fertilizer+ organic sulfur+ mulch, 25 mineral fertilizer + organic fertilizer + powdery sulfur + mulch. The results showed that different fertilizer treatments had significant effect on the yield (P<0.01) and bunch weight (P<0.05) but there is no significant effect on fruit set, percentage of fruit falling, number, length and width of the spathe. Quantitative characteristics of fruits including fresh and dry weight, volume, length and diameter of fruit, weight, length and diameter of seed and pulp to seed ratio also qualitative characteristics of fruit include reducing sugar, total sugar, pH, titratable acidity, Brix, moisture, phosphorus and potassium had no significant effect.
