Evaluación de tres distancias de plantación de lechuga (Lactuca sativa L.) con aplicación de riego por goteo

Abstract

The present study on the determination of the production of lettuce (Lactuca sativa L. ) with different planting distances through the application of drip irrigation, was carried out in the parish Juan Benigno Vela located in the South West of Ambato canton, province of Tungurahua, its geographical coordinates 01° 19' 41.97" South latitude and 78° 43' 04.24" W longitude, with the purpose of determining the adequate spacing to obtain a better yield in production, the distances used were 0,30, 0,40 and 0,50 m between rows and 0,3 m between plants. A randomized block experimental design with three treatments and five replications was used. To obtain the results of the cabbage weight and diameter variables, the data were analyzed using the Tukey test at 5%. The data of the variables obtained were fundamental elements for obtaining the statistical analysis, with which it was possible to conclude that the treatment that obtained the best results is H2 with a planting distance of 0.3m*0.4m, reaching a weight of 747.07 g and a yield of 49.939 kg/ha, As for treatments H1 and H3, the results were inferior to those of treatment H2, in terms of water volume, treatment H2 provided 1.56 mm/day during the crop cycle, while treatment H1 provided 2.12 mm/day and treatment H3 1.18 mm/day, thus inferring that treatment H2 provided the necessary volume of water until the commercial maturity stage. Finally, with regard to the benefit-cost ratio, the treatment that gives us the highest profit in relation to ha is the H2 treatment with $2.06 profit, while the H3 treatment obtained $1.59 and the H1 treatment resulted in $1.49 profit, being these two treatments profitable, but with lower profit
