This study was designed to optimize the use of organic and chemical fertilizer combinations in the production of red pepper to reduce costs and avoid environmental pollution. Therefore, the effect of 12 different treatments of animal and chemical fertilizers was studied in a randomized complete block design on yield and active ingredient (Capsaicin) red pepper. Variance analysis of the data indicated significant differences at 1% level among the different treatments. Mean comparisons with Duncan's test at 1%, revealed that the maximum yields with averages of 7.6, 7.3 and 7.2 ton.ha-1 were obtained in the treatment numbers of 10 (Organic, nitrogen, phosphorus and potassium, respectively. 20 ton.ha-1, 60, 50 and 50 kg.ha-1), 12 (Organic, nitrogen, phosphorus and potassium, respectively, 40 ton.ha-1, 20, 16 and 16 kg.ha-1), and 8 (40 ton.ha-1 of organic fertilizer) respectively. Variance analysis of active ingredient percentage showed significant differences at the 5% level. Highest active ingredient with average 0.1747% was obtained in treatment of number 3 (nitrogen, phosphorus and potassium, respectively 150, 100 and 100 kg.ha-1). In general it can be concluded that yield could be increased by using a proper combination of organic and chemical fertilizers.
