Abstract
Rosa damascena Mill is one of the most important essential and aromatic plants of the rose family, which has a high economic and nutritional value. Iran is one of the most important countries producing this plant in the world. Considering the value and importance of this plant, a research aimed at investigating the effect of zinc fertilizers and humic acid on the physiological and biochemical characteristics of rose (Rosa damascena Mill.) in 1401 on three-year-old rose plants grown in Zabul University in a factorial manner It was implemented in the form of a randomized complete block design with 3 replications. In this research, the first factor includes two types of zinc-containing fertilizers, including zinc sulfate with concentrations of 1, 2, and 4 grams per liter and zinc chelate with concentrations of 1, 2, and 4 grams per liter, and the second factor includes humic acid with amounts of 2 , 4 and 6 grams per liter and in the form of irrigation fertilizer. The investigated traits in this research included plant height, amount of photosynthetic pigments, carbohydrate, phenol, flavonoid, number of flowers and flower yield. According to the results obtained from this research, the combined application of zinc sulfate, zinc chelate and humic acid treatments was significant on all investigated traits except the weight of fully opened petals at the level of 1% and 5%. According to the results, the use of fertilizer treatments caused a 75.55% increase in the number of flowers, a 38.37% increase in the carbohydrate content of the plant, and a 213.66% increase in the total chlorophyll content of the daisy plant. Therefore, by replacing harmful chemical fertilizers with these organic materials, an effective and important step can be taken in order to reduce environmental pollution.
