Item Evaluación del rendimiento de lechuga (Lactuca sativa L. var. Coolguard) con la aplicación de dos extractos de algas en el cantón Cevallos(2023-09) Cueva Gómez, Kerly Nicol; Dobronski Arcos, Jorge EnriqueThe present study was carried out in the properties of the experimental farm Docente Querochaca of the Cevallos canton, Tungurahua province, with the purpose of evaluating the yield of lettuce (Lactuca sativa L. var. Coolguard), using artisanal extract of freshwater algae from Spirogyra species, applied with three doses compared to a commercial algae extract Nodosum®. An experimental design with randomized blocks was carried out with seven treatments in three repetitions. The data obtained were analyzed using ADEVA and the Tukey test at 5%, observing the following results: For the variables cabbage diameter, plant height, cabbage mass, root length, cabbage color and crop yield, showing the following results, the most outstanding being T1 for the yield variable with an average of 24.80 t/ha and for plant height the best treatment was (T2) with an average height of 19.78 cm, composed of the product 1 (artisanal seaweed) with the dose (2.5 ml), as well as the treatment that stood out was T1 composed of product 1 (artisanal seaweed) with dose 1 (1.5 ml) in the cabbage diameter variable with an average of 139.58 mm in diameter, that is to say that these two treatments had better agronomic characteristics, for which we can say that these variables were better adapted to the area where the research work was carried out, while the composite T3 treatments by (P1D3); T4 (P2D1); T5 (P2D2); T6 (P2D1) and Control presented lower values than T1 (P1D1) and T2 (P1D2)
