In order to investigate the effect of different chemical, organic and biological fertilizers on some qualitative and quantitative features of Rosa damascene Mill, a research was conducted in the form of randomized complete blocks design, in three replications in Alborz, Isfahan and Yazd provinces. The investigated treatments were as follows: 1- control (no fertilizer), 2- 174 kg of urea fertilizer, 174 kg of triple superphosphate, 100 kg of potassium sulfate (recommendation based on soil test), 3- (130 kg of urea fertilizer, 130 kg of triple superphosphate, 75 kg of potassium sulfate (75% recommendation based on soil test) + 10 tons per hectare of rotted cow manure (fertilization in the first year of implementation, early April), 10-4 tons per hectare of rotted cow manure (fertilization in the first year of implementation, early April), 5- (130 kg of urea fertilizer, 130 kg of triple super phosphate fertilizer, 75 kg of potassium sulfate) (75% recommendation based on soil test) + annual consumption of 40 liters per hectare of humic acid (fertilization at the beginning of the growing season and before flowering) 6- (130 kg of urea fertilizer, 130 kg of triple superphosphate fertilizer, 75 kg of potassium sulfate) (75 percent of the recommendation based on the soil test) + four liters per hectare of flavite fertilizer diluted with irrigation water is used in the root environment. 10-7 tons per hectare of rotted cow manure (fertilization in the first year of implementation, early April) + four liters per hectare of flavite fertilizer diluted with irrigation water is used in the root environment, 8- four liters per hectare of flavite fertilizer diluted with Irrigation water is used in the root environment + 10 tons per hectare of rotten cow manure (fertilization in the first year of implementation, early April) + annual consumption of 40 liters per hectare of humic acid (fertilization at the beginning of the growing season and before flowering) and 9-4 A liter per hectare of flavite fertilizer diluted with irrigation water is used in the root environment.
Fertilizers of high consumption elements as well as organic fertilizers were used in the form of chalk fertilizer and biofertilizers were used together with irrigation water. In each treatment, 10 mohammadi plants were considered, and tape irrigation system was used for irrigation. Every year, with the beginning of flowering, flowers were sampled almost every other day for a month. Characteristics such as the number of flowers, flower weight, dry and wet weight of bolls and wet and dry weight of petals were investigated. The data related to the quantitative and qualitative traits of this plant under different treatment conditions (chemical, organic, biological) were recorded and analyzed using SAS statistical software. Based on the results, all the treatments, including the use of animal manure, humic acid, NPK and flavite chemical fertilizers, as well as the combined use of these fertilizers, caused a significant improvement in the traits measured in the plant compared to the control. According to the results of two years of testing, in Alborz province T5 fertilizer treatment (simultaneous use of NPK fertilizers and humic acid fertilizer), in Isfahan province T3 fertilizer treatment (simultaneous use of NPK fertilizers and animal manure), in Yazd province T2 fertilizer treatment (concurrent use NPK fertilizers) has had the best results
