In order to study the effect of different chemical and organic fertilizers on the morphological characteristics of physalis an experiment as split plot based on randomized compelet blok design was done in the greenhouse. The main plot includes organic fertilizer at four levels (control, farmyard manure, vermicompost and the combination of farmyard manure and vermicompost) and sub plot included different chemical fertilizers at six levels (control, NPK chemical fertilizer, potash chelate 28%, iron nano chelate 15%, superahyomic and biomass biofertilizer). The results showed that in the culture medium of farmyard manure + vermicompost and with the application of nano-biological biofertilizer, the highest fruit yield per plant (2.29 kg/plant), vitamin C (8.53 mg/g fresh weight), phenol (39.90 mg GA/DW) and total flavonoids (6.89 mg QA/DW), antioxidant properties and soluble solids (16.5 Brix) are obtained in the fruit. The highest and lowest concentrations of nitrogen, phosphorus and potassium of shoots were observed in the treatment of vermicompost + farmyard manure, respectively, along with nano-fertilizer, biofertilizer and control treatments. Considering the favorable effect of vermicompost in the culture medium and biological fertilizers in comparison with the control treatment and chemical fertilizer treatment, it can be considered in the cultivation and feeding programs of physalis in addition to maintaining and improving traits related to growth and yield a healthy product can be offered without chemical fertilizer residues.
