Medicinal plants and their products have gained a special value and position in recent years due to factors such as high economic value and low cost of their production. This research was conducted in a complete randomized block design with 8 treatments (Golder 5 and 10%, Kalpura 5 and 10%, Dermene 5 and 10%, Golder 5% + Kalpore 5% + Dermene 5% and custom of the region (control). It was performed in Kahnuj, Kerman province. The results showed that the maximum fresh and dry weight of the plant was observed in the control treatment (1150 and 200 grams). The highest yield and marketable yield per hectare (53.8 and 44.7 tons), firmness (4.40 kg/cm2), chlorophyll a, b and total and leaf carotenoids (25.3, 95. 4, 30.2 and 4.36 mg) as well as chlorophyll a and chlorophyll of the whole fruit (0.208 and 0.210 mg) were related to Golder 5 + Calpore 5 + Dermene 5 treatment.
