Abstract
Considering the global population growth and increasing demand for agricultural products, the use of organic fertilizers as a suitable alternative to chemical fertilizers is of particular importance. This study was conducted with the aim of evaluating the effect of applying compost and liquid fertilizer obtained from common moto fish(Encrasicholina punctifer) on some traits of Shahab hot pepper plant (Capsicum annuum L) in the greenhouse conditions of Hormozgan University. In this research, after collecting the sampels , compost and liquid fish fertilizer were prepared and experimental treatments were carried out in the form of a completely randomized block design in the form of pot culture with three repetitions, including agricultural soil without liquid fertilizer, agricultural soil + liquid fish fertilizer with a ratio of 1:10, agricultural soil. + liquid fish fertilizer with a ratio of 1:20, 50% compost without liquid fish fertilizer, 50% compost + liquid fish fertilizer with a ratio of 1:10 and 50% compost + liquid fish fertilizer with a ratio of 1:20.After 64 days, the plants are completely removed from the pot and some morphological traits (plant height, stem and root diameter and length, fresh and dry weight of aerial and dry organs) and physiological (chlorophyll, carotenoid, antioxidant, phenol , flavonoid and peroxidase enzyme activity) was measured.The results of analysis of variance showed that the use of manufactured fertilizers has a significant effect on plant traits.So that the highest values of traits were observed in treatments containing compost and liquid fish fertilizer with a ratio of 1:10.
