Aims: The objective of this work was to evaluate the effects of the application of organic fertilizer in different concentrations under the initial development of lettuce plants.

Study Design: The experimental design was completely randomized with four replications of 5 plants for each treatment.

Place and Duration of Study: The present work was carried out in the premises of the Escola Família Agrícola de Ladeirinhas 'A' - EFAL, located in the Municipality of Japoatã in the State of Sergipe, Brazil. Between September 2022 - December 2022.

Methodology: Daily applications of organic fertilizer were performed in lettuce plants of Cv. Repolhuda, with a volume of 200 ml per plant, in the morning and afternoon, except for days with precipitation. To evaluate the effect of organic fertilizer, different concentrations 0% (control) were used. 5%, 10% and 20%. The following variables, fresh mass, number of leaves, plant height and root system length were analyzed.

Results: The results obtained with the application of organic fertilizer, showed that the plants that were fertilizer showed better initial development of lettuce Repolhuda, when compared with plants that did not receive the application of fertilizer for most of the variables analyzed in this study, and the concentration of 20% presented the best result.

Conclusion: The results obtained with the application of organic fertilizer, showed that the plants that were fertilized showed better initial development of lettuce.

Keywords: Agriculture, organic fertilizer, plant growth, plant nutrition, soil fertility, sustainability
