Evaluación de dos sistemas de producción aeropónico e hidropónico en lechuga (Lactuca sativa l.) var. Crispa bajo cubierta, ubicado en el cantón Francisco de Orellana.

Abstract

The present investigation aims to evaluate two aeroponic and hydroponic producción systems in lettuce (Lactuca sativa L.) var. crispa under cover, the total area of the trial was 24 m2, a randomized complete block design was used with two treatments and three replications with 5% DMS test. The following parameters were evaluated: plant height, leaf width, leaf length, number of leaves, root length, plant weight at 15 days, 30 days and at harvest (40 days), the yield per net plot and per hectare, and the benefit-cost ratio were calculated. It was determined that treatment T1 (hydroponic system) got the greatest plant height at 15, 30 days and at harvest with 23.50 cm; 31.08 cm and 34.55 cm respectively. The largest leaf width was obtained by T1 at 15 days, 30 days and at harvest with 5.57 cm; 7.44 cm and 7.84 cm respectively. The longest leaf length was obtained by T1 at 15 days, 30 days and at harvest (40 days) with 10.68 cm; 13.71 cm and 14.44 cm respectively. The highest number of leaves reached by T1 at 15 days, 30 days and at harvest with 10.37, 16.47 and 18.7 leaves respectively, the highest root length reached by T2 (aeroponic system) at 15 days, 30 days and at harvest with 9.88 cm, 10.37 cm and 10.91 cm respectively. T1 got the highest plant weight at harvest with 32.31 g, the highest yield with 4094.53 kg/ha, and the highest benefit-cost ratio of 3.80 dollars, which corresponds to 280.12% profitability. The treatment T1 by means of the evaluations carried out overcame in almost all the variables to the treatment T2 (aeroponic system), it was determined that it is the best treatment for the production of lettuce (Lactuca sativa L.) var. Crispa in Francisco de Orellana canton.
