Abstract

The purpose of this research was to investigate the effect of organic fertilizers on the morphological and physiological characteristics of peppermint plant (Mentha piperita L.). For this purpose, a research was carried out in 1402 in the research greenhouse of Yazd University in the form of a completely randomized design with 4 repetitions of execution and the effect of different amounts of chicken and pigeon manure with concentrations of (10, 20 and 30 grams in solution in 1.5 liters of water in a pot, containing 5 kg of soil) and control were investigated on peppermint plants. The comparison results of the average traits of the highest plant height (36 cm), the number of stolons (7), fresh and dry weight of aerial parts (25 and 6 grams), root weight (55 grams), root volume (52 ml) in the treatment of 30 grams of fertilizer Pigeon gave the highest number of leaves (300) and stolon length (70 cm) in the treatment of 30 grams of chicken manure, and the number of branches (53) and dry weight of roots (14 grams) in the treatments of 20 and 10 grams of chicken manure, respectively. Also, the highest amount of chlorophyll a (24 mg/g), total chlorophyll (30 mg/g) and carotenoid (11 mg/g) in the treatment of 20 grams of pigeon manure and the highest amount of chlorophyll b (8 mg/g) and proline (160 μg/g) and antioxidant (95 mg/g) were obtained in the treatment of 30 grams of pigeon manure and 10 grams of chicken manure, respectively.
