Evaluación del lixiviado del humus de lombriz en la producción de la lechuga de hoja (Lactuca sativa L).
(2024-02) Álvarez Molina, María Inmaculada; Zurita Vásquez, José Hernán
This project was carried out on the property of Mr. José Luis Alvarez in Tena, province of Napo , with the purpose of evaluating the efficiency of worm humus leachate in the yield of the leaf lettuce crop (Lactuca sativa L) , applying the treatments of worm humus leachate in the crop with three doses , two application frequencies , three repetitions and a control . A completely randomized block experimental design was used with six treatments plus a control with three repetitions . In the results of the test of means in terms of plant weight, root length , number of leaves and coverage diameter , no significant statistical difference was found between the data obtained from the analysis of the Tukey test . The root volume was the only variable that obtained a response with a statistically significant difference , with the D2F2 treatment being the outstanding value with an average of 4.58ml , letting us know that the leachate from the worm humus applied at a dose of 350ml/L every 15 days , provides a benefit for root development , causing it to have greater root volume . It should be noted that the treatments that obtained a significant mathematical difference in the different variables analyzed were the following , in the case of plant weight as well as the number of leaves , the D3F2 treatment applying 450ml/L . In root length the D2F1 treatment with an application of 350ml /L and in root diameter the D1F2 treatment applying 250ml /L .
