Abstract: El presente estudio coloca a ocho distintos cultivares de lechuga, Lactuca sativa L. bajo condiciones de un manejo agronómico orgánico en un campo en el distrito de La Molina, provincia Lima, con el objetivo de evaluar su rendimiento, materia seca, peso fresco, diámetro de cabeza, altura de la planta y número de lechugas sanas cosechadas. Se emplea el diseño experimental de bloques completamente al azar (DBCA) en un campo experimental abierto de 47m x 12m dividido en cuatro bloques (repeticiones), cada bloque consta de ocho diferentes cultivares de lechuga (tratamientos), obteniendo un total de 32 parcelas experimentales, cada parcela está formada por tres líneas de lechugas sembradas bajo el sistema de distribución a tres bolillos, con una separación de 0.25 m entre plantas y la aplicación de riego por goteo. Los métodos estadísticos usados son ANOVA y Tukey con 0.05 de coeficiente de significancia. El experimento expone entre sus resultados diferencias significativas para las variables de rendimiento, materia seca, peso fresco, diámetro y número de lechugas sanas, no hubo diferencia significativa para altura de la planta. Se destaca un patrón de comportamiento similar entre los cultivares perteneciente a las lechugas de tipo hoja, y lo mismo para las lechugas de tipo iceberg. Las pérdidas de lechugas considerables por no llegar a un estándar de calidad se dan en los tratamientos correspondientes a los tipos de lechugas iceberg por el apiñamiento, poco espacio de aeración, alta humedad y altas temperaturas que traen consigo la presencia de hongos y bacterias. El control sanitario de plagas y enfermedades se hizo mediante prácticas culturales y aplicaciones de productos permitidos por el reglamento técnico peruano orgánico. Se recomienda un mayor distanciamiento entre plantas para los tipos de lechuga iceberg.
The present study places eight different lettuce cultivars, Lactuca sativa L., under organic agronomic management conditions in a field in the district of La Molina, Lima, with the objective of evaluating their yield, dry matter, fresh weight, diameter, heigth and number of healthy lettuce harvested. The experimental design of completely randomized blocks (DBCA) was used in an open experimental field of 47m x 12m divided into four blocks (replications), each block consists of eight different lettuce cultivars (treatments), obtaining a total of 32 experimental plots, each plot is formed by three lines of lettuce planted under the distribution system of three bolls, with a separation of 0.25 m between plants and the application of drip irrigation. The statistical methods used were ANOVA and Tukey with 0.05 coefficient of significance. The results of the experiment show significant differences for yield, dry matter, fresh weight, diameter and number of healthy lettuce plants; there was no significant difference for plant length. There was a similar pattern of behavior among the cultivars belonging to the leaf type lettuce, and the same for iceberg type lettuce. Considerable losses of lettuce due to not reaching a quality standard occur in the treatments corresponding to iceberg lettuce types due to crowding, little aeration space, high humidity and high temperatures, which bring with them the presence of fungi and bacteria. Sanitary control of pests and diseases was done through cultural practices and applications of products permitted by Peruvian organic technical regulations. A greater distance between plants is recommended for iceberg lettuce types.
