Evaluación de tres enraizantes en plántulas de lechuga (Lactuca sativa L.) mediante el método de raíz flotante en la parroquia Mulalillo del cantón Salcedo, provincia de Cotopaxi

Abstract

In the present work the effect of three rooting on lettuce seedlings (Lactuca sativa L.) cultivated under the floating root method was evaluated, the experiment was performed under cover (ceiling only), two applications were made for the second application to (Lambda cyhalothrin 0.5 cc / l; methyl thiophanate 1 g / l) were used for the control of pests and diseases, the study was carried out in Mulalillo, Salcedo , Cotopaxi Province, The objectives were: 1. To determine the best rooting for the development and water consumption of lettuce plants. 2. Determine the best dose and frequency of rooting for the development of lettuce plants. 3. Carry out an economic analysis of the treatments used. Three rooting were tested: E1 (Carboroot) in doses of 1 and 2 ml, E2 (Agrostemin) in doses of 1 and 2 g, E3 (Meristemroot) in doses of 1 and 2 ml, plus a standard fertilization as shown in Table 9 for each treatment, versus a control based on fertilization alone. The statistical design used was Completely Randomized Block Design (DBCA) with four replications, with a factorial arrangement between rooting and doses (3x2) +1. Lettuce responded significantly better to rooting E2D2, reaching the highest plant height and the highest fresh weight yield per plant. Key words: rooting, lettuce, floating root.
