In order to study the effects of biofertilizers of nitroxin (0, 2, 4 L.h^-1) and biosulphur (0, 2, 4 kg.h-¹) Containing “plant growth promotor Bacteria” on quantity and quality of medicinal plant of winter cherry (Physalis alkekengi L.) an experiment in a factorial experiment based on randomized complete block design with nine treatments (Nitroxin 2 and 4 L.h^-1, Biosulphur 2 and 4 kg.h-¹, Nitroxin 2 L.h^-1 + Biosulphur 2 kg.h-¹, Nitroxin 2 L.h^-1 + Biosulphur 4 kg.h-¹, Nitroxin 4 L.h^-1 + Biosulphur 2 kg.h-¹, , Nitroxin 4 L.h^-1 + Biosulphur 4 kg.h-¹ and No Biofertilizer) and three replications was conducted in agricultural faculty of Zanjan University in 2016. Results of this experiment showed that biofertilizers of Nitroxin and biosulfur had significant effect on growth indices, yield and quality of winter cherry but weight of Calyx not affected by experimental treatments. The maximum Plant height  (53 cm), stem diameter (6.1 mm), internod distance (7.33 mm), leaf area (422.3 cm²), number of branches (58), Aerial part fresh weight (371.3 g), Aerial part dry weight (78 g) were obtained in integrated treatment of four liters nitroxin with four kilograms of biosulfur. The maximum fruit weight (1.96 g), fruit diameter (1.96 mm), total yield  (6.82 t.h^-1), Chlorophyll a (4.01 mg.g^-1 leaf fresh weight), leaf nitrogen content (3.02 percent), leaf sulfur content (0.20 percent) were obtained in integrated treatment of four liters nitroxin with four kilograms of biosulfur. Also, the most total phenol (14.07 mg/g fruit DW), carotenoids (12.16 mg/g fruit FW), anthocyanins (17.7 mg mg/g fruit DW), and physaline (1.56 percent) obtained in treatment of four liters nitroxin per hectare. Most of the chlorophyll b (2.76 mg/g leaf fresh weight) in integrated treatment of two kilograms per hectare of biosulfur with four liters per hectare of nitroxin. Overall, based on results it seem that biofertilizers of Nitroxin and biosulfur application can increase the economic performance, quality and quantity characteristics of winter cherry compared to control.
