Impact de l’application d’un bio fertilisant à base de l’ortie ( Urtica dioica L. )sur la croissance de tomate (Solanum lycopersicum)

Abstract

The study aimed to develop an effective natural fertilizer that could compete with chemical fertilizers, which are considered harmful to humans and the environment. A natural fertilizer was produced from the manure (Urtica dioica L.) of stinging nettle after conducting the necessary research and theoretical study on the plant and its properties. The field experiment was then carried out by comparing the nettle fertilizer to a chemical fertilizer across three groups, each with three repetitions(Group 1 was irrigated with nettle manure, Group 2 was irrigated with chemical fertilizer, Group 3 served as the control and was irrigated with tap water). The analyses obtained after using the nettle fertilizer, compared to the chemical fertilizer, showed that the organic fertilizer produced positive morphological results on tomato plants. Early flowering and fruiting were observed compared to the group treated with chemical fertilizer. Good results were also recorded in total chlorophyll content, relative water content, and leaf area. What sets nettle fertilizer apart is that, in addition to being a plant growth stimulant, it is also 100% natural with no chemical additives, making it environmentally friendly.
