Abstract
En el presente trabajo de investigación, se evaluó la influencia de recircular la solución nutritiva en un sistema hidropónico NFT en el rendimiento y calidad de la lechuga (Lactuca sativa L.) variedad Tropicana. El experimento se desarrolló bajo un diseño completo al azar con seis tratamientos y cinco repeticiones en las instalaciones del centro de producción Eco-Verduras, ubicada en el Anexo Vista Alegre, distrito de Imperial, provincia de Cañete y departamento de Lima durante los meses de febrero - abril del 2021. Las recirculaciones evaluadas fueron 0, 1, 2, 3, 4 y 5 frecuencias diarias, por un tiempo de 15 minutos. El sistema de recirculación fue accionado mediante una electrobomba de encendido manual, a las 7:00, 11:00, 13:00, 15:00 y 18:00 horas. Los mejores resultados de rendimiento y calidad se constataron con cuatro (T5) y cinco (T6) recirculaciones de la solución nutritiva, con un rendimiento total de 72.10 t.ha-1 y 73.84 t.ha 1 respectivamente, a comparación del testigo absoluto 16.9 t ha-1 (T1); similar efecto se constató con el peso de planta, 434.29 g/planta (T5) y 444.89 g/planta (T6). Respecto a la calidad se observó efecto significativo, constatando mejores resultados con cuatro y cinco recirculaciones de la solución, lo cual logró mayor área foliar 7575.83 cm2 /planta (T6) y 7346.71 cm2 /planta (T5) a comparación del testigo absoluto 2365.32 cm2 /planta (T1); para masa fresca de hoja se obtuvo 433.30 g/planta (T6) y 422.82 g/planta (T5) a comparación del testigo absoluto 92.32 g/planta (T1) y en número de hojas con 40 und/planta (T6) y 38 und/planta (T5) a comparación del testigo absoluto 22.4 und/planta (T1). En la presente investigación es conveniente optar por frecuencias de cuatro (T5) recirculaciones de la solución nutritiva.
In the present research work, the influence of recirculating the nutrient solution in an NFT hydroponic system on the yield and quality of lettuce (Lactuca sativa L.) variety Tropicana was evaluated. The experiment was developed under a complete randomized design with six treatments and five repetitions in the facilities of the Eco-Verduras production center, located in the Vista Alegre Annex, district of Imperial, province of Cañete and department of Lima during the months of February. - April 2021. The recirculations evaluated were 0, 1, 2, 3, 4 and 5 daily frequencies, for a time of 15 minutes. The recirculation system was activated by a manual ignition electric pump, at 7:00, 11:00, 13:00, 15:00 and 18:00. The best yield and quality results were found with four (T5) and five (T6) recirculations of the nutrient solution, with a total yield of 72.10 t.ha-1 and 73.84 t.ha-1 respectively, compared to the absolute control 16.9 t ha-1 (T1); A similar effect was observed with plant weight, 434.29 g/plant (T5) and 444.89 g/plant (T6). Regarding quality, a significant effect was observed, verifying better results with four and five recirculations of the solution, which achieved a greater leaf area 7575.83 cm2 /plant (T6) and 7346.71 cm2 /plant (T5) compared to the absolute control 2365.32 cm2 / plant (T1); For fresh leaf mass, 433.30 g/plant (T6) and 422.82 g/plant (T5) were obtained compared to the absolute control, 92.32 g/plant (T1) and in number of leaves with 40 units/plant (T6) and 38 units. /plant (T5) compared to the absolute control 22.4 units/plant (T1). In the present investigation it is convenient to opt for frequencies of four (T5) recirculations of the nutrient solution.
